Samsung SM951 NVMe on Asus x99 Deluxe – Baseclock <> CPU strap magic

“I did buy a new little toy, the Samsung SM951 NVMe 512 GB M.2 SSD Drive.”

 

I tested the Samsung SM951 NVMe M.2 on Windows 7 and Windows 10 by using the M.2 slot on the motherboard and by using the M.2 addon card which comes shipped together with the Asus x99 Deluxe.

System:

  • Asus x99 Deluxe BIOS 1901 @ ~ 125.5 MHz Baseclock (while 125 MHz CPU strap)*
  • i7-5930K @ ~ 4.4 GHz, 125 MHz Strap, 1.31 Vcore, 1.24 Vcache, 1.24 Vsysagent
  • NV GTX 770
  • 16 GB Corsair DDR4 @ ~ 3 Ghz, 1.35 Vmem
  • 2x  SSD OCZ Vertex 2 (Sata2) (Raid0)
  • 2x  Seagate HDD  3 TB/HDD (Raid1)
  • PSU Corsair AX1200i (why the heck an AX1200i?)
  • Corsair Obsidian 450 D

 

*The ‘Baseclock’ and the ‘CPU strap’ will become more important over time in this SSD benchmark drama-post. I couldn’t think of the Baseclocks offset to the CPU strap affecting the benchmarks. At first i thought its overclocking on this motherboard in general, which affects the benchmarks.
Theres is an old problem known to Windows 8 respecting system timers and clocks leading to incorrect benchmarks. Seems that Windows 10 and 7 are affected too.

IMAG1047“No matter which OS or which PCIe slot i use, the SSD seems to be throttled or bottlenecked.”

 

 

 

“As soon as the Baseclock is higher than my CPU strap. The benchmarks do no longer represent the correct values!”

“Baseclock frequency below CPU strap frequency may result in the same behaviour”

“You can say that any offset between the CPU strap and Baseclock may result in “bogus” or shifted benchmarks”

 

 


The trip to find the cause for the benchmark results:

 

 

“A bad driver can also act as a bottleneck.”

 

First ATTO run on Windows 7 – smells like bottleneck.

The SM951 M.2 2280 MZVPV512 NVMe SSD is using the Asus x99 Deluxe onboard M.2  slot.

Some people may not be able to see the device on OS side (Win 7 !). And those people may make their way through the internet and find a “Hotfix” by Microsoft (Windows6.1-KB2990941-v3-x64). I did  install the Hotfix. It may work for you but you may not get 100% out of your device.

Because of the “bad” results i got, i did install Windows 10. I did hope that i can get the drivers off the SSD when installing a fully UEFI compatible OS. But …

“There is a throttle …”

 

 

There is a throttle

Keep in mind that the SM951 NVMe model indeed is able to throttle itself to prevent overheating. What if this throttle mechanic is not working properly? Keep that in mind. It is possible …

… but it’s not  threating us here. 🙂

 

 

“Expectation”

 

First ATTO run on Windows 10 – smells like bottleneck.

…even with Windows 10 i still do seem to be using the NVMe drivers provided by Windows (or worse the previously installed Hotfix).

The SM951 M.2 2280 MZVPV512 NVMe SSD is using the Asus x99 Deluxe onboard M.2  slot. Comparing with other tests on the internet you expect read speeds > 2.2 GB/s.

Second ATTO run on Windows 10 – smells like bottleneck.

The SM951 M.2 2280 MZVPV512 NVMe SSD is using the Asus x99 Deluxe onboard M.2  slot. This time i did set x4 mode manually and did disable a couple unneccessary stuff in the BIOS to make sure nothing weird is going on there. With no reward. Same results.

“Alternative”

 

 

Third ATTO run on Windows 10 – smells like bottleneck.

This time i did use the Hyperkit Card shipped with the Asus x99 Deluxe. Same results.

The drivers Windows 10

Just for the records. Unfortunately i did not make screenshots of the Windows 7 drivers. The MS drivers were mentioned already in the past when it led to problems with NVMe like this. But they do pretty well now. They improved it

BUT

“It’s not the drivers fault”

 

But it turned out, that it is not the driver who is causing these “bad” results.

Silence.

 

“The drama …”

 

 

The relief – no bottleneck

It was the fact that the System was overclocked. As soon as i lowered the Baseclock back to 100 MHz. The results became better. The Baseclock was previously set to 125.5 Mhz. I then had read results > 2.2 GB/s and write results > 1.7 GB/s with SM951 SSD used as non-system drive. Unfortunately i did not make a screenshot of it. (What i did not think of here is, that the CPU strap also was set back to 100 MHz – the same frequency the Baseclock is running at)

Last ATTO run on Windows 10 @ 100 MHz Baseclock (system drive!)

However i then did configure the Samsung SM951 NVMe SSD as system drive. The performance results would be a bit better when it is not used as system drive.

SM951 M.2 2280 MZVPV512 NVMe SSD, Baseclock @ 100 MHz, system drive !, connected using onboard M.2 slot

 

(I noticed the following before i finally discovered that the baseclock<>CPU strap offset is causing the shifted benchmarks, but i then ignored it because of the Anti Virust software which came out as a potential cause when configured to be super sensitive)

What’s left to say?

If you multiply the old results with (Baseclock of 125.5  MHz) with 1.255 you get results matching pretty well with the results of Baseclock of 100 MHz.

For example the 8 MB result of the first run:

1398442 Write     x     1.255 = 1755044,71
1717986 Read     x     1.255 = 2156072,43

 

  • Was the higher Baseclock really throttling or bottlenecking  the SSD?

 

  • Or is it just the benchmark not being aware of a higher Baseclock  and mucking up the results? Possible that the realtime clock is affected by Baseclock?

 

  • Will i ever be able to overclock and enjoy the Samsung SM951 NVMe performance at the same time?

 

Apart from ATTO i sure did run other benchmarks on the overclocked system and they sure came up with not the same results because they dont “measure” all the same way but they all left you thinking of either a bottleneck or throttle. I unfortunately made no screenshots of the runs before but i will present some with stock clock speeds and Samsung SM951 as system drive.

As system drive and some disturbing stuff going on the whole time in the background the results are OK.  But to answer the questions of “How did the Baseclock affect the benchmarks?”  or “Will i ever be able to overclock and enjoy the Samsung SM951 NVMe performance at the same time?” we would’ve to pick another route.

 



As soon as the Baseclock is higher than my CPU strap. The benchmarks do no longer represent the correct values!

No matter if the ‘useplatformclock’ is enabled or not. The benchmark results do look like the SSD was throttled or bottlenecked as soon as the ‘Baseclock’ is higher than the ‘CPU strap’. I thought i revealed my Anti Virus software to be the root of al evil but it was not.

The realtimeclock RTC

Just for the records:
The value for useplatformclock was initially set to Yes on Win 10
The default value on Win 7 may be unset or No

This fact was one thing that concerned me that i was right following the Baseclock- / hwclock- / timer-way

 

bcdedit_useplatformclock_yes_windows_10_cmd_shell
‘bcdedit’ output while not a single parameter was handed over

I did play with this setting with overclocked and non overclocked system. But it took some days to finally notice that it has something to do with the ‘Baseclock’ and ‘CPU strap’. I did step away from this setting, when i thought it had something to do with the Anti Virus software. However this setting does not help to solve the problem on systems with not equal Baseclocks and CPU straps.

 

“Finally i could narrow down the cause but i couldn’t solve it yet.”

 

 



 

 

What i thought and wrote, when it seemed to be the Anti Virus software compromising the benchmark results. I trapped myself when i quick-overclocked the system again (by leaving Baseclock and CPU strap the same) to test different situations:

OK folks.. scratch all that

i tend to play now with “useplatformclock” (bcdedit) and overclock the system again. But guess what. Neither overclocking nor playing with useplatformclock variable did make any difference to the benchmarks.

 
But i think i revealed who was in charge for the performance trouble in the beginning …

 

… it was …

… my freaking Anti Virus software!

 

I did compare the useplatformclock setting of a Windows 7 system to my Windows 10 system to make sure that this could be a true reason for the mucked up results and it turned out to really be a root for the mess. You now need to know that i went from Windows 7 to Windows 10, just because of this performance mess, by upgrading Windows 7 to Windows 10. There was a chance that some important settings wern’t migrated or merged correctly. Upgrading does leave room for a lot of mistakes at this level. Later on i made a complete fresh install of Windows 10 and this time i installed it directly on the SM951 NVMe SSD, but as i already mentioned, the results didnt change anymore no matter what i touched.

  • Because the Baseclock and CPU strap are equal during this period i never had any shifted benchmark results again

I was freaking out because i really need to know the cause for the performance drama at the beginning to wipe out any missconfigurations and make sure every component is running fine and smooth and then when i was almost giving up i took the Anti Virus software into account.

It’s not that i never was thinking about it but i did underestimate it and i also wasn’t aware anymore of the configuration of my Anti Virus software.

  • Apart from the Baseclock and CPU strap there was only one more thing that could form a bridge  between all these odd things.

As tired as i might be the Anti Virus software was the only thing that could “transport” or “connect” the performance mess from one OS to another – if you are changing the OS by upgrading it. The complete fresh install i mentioned earlier wasn’t affected by the Anti Virus software, because i didn’t install it, but the old Windows 7 and the upgraded Windows 10 installations both had the same Anti Virus installation running.

  • But they also had a Baseclock CPU strap offset

So i went ahead and installed the Anti Virus software. With said software running in the background i still did get normal results. Again that did hit me hard. I thought i got it. But in the same moment, i realized that i didn’t change it’s configuration.

With the configuration window infront of me the settings, i usually made, came into my mind and i set them according previous installations of this Anti Virus software. And guess what. I finally could reproduce the ‘BAD RESULTS’. With its settings set back to defaults, everything is fine. No performance issues.

I know what some people will say. 🙂 All i can respond is, that i am aware of Anti * ware digging into things and some other things. My problem in this case relies more in the experience i had with this Anti Virus software. I’m using it for years now and never had any issues like denied or failed or interrupted installations due to scanning attempts or  or any kind of interruption that would ask for my attention or a closer look. It always had been the perfect Anti Virus software for me. “Install it and forget it”. Now it got its revenge for all the years not paying attention, not treating it like a tamagotchi and not taking care of it.

I promise i will treat you better now, dear Anti Virus.

But i can say now that i was right not believing my Anti Virus software to be the one compromising the results.

Another BIOS release for x99 Deluxe

Asus just did release another BIOS for the Asus x99 Deluxe. We are now at Version 1601 1702.

With BIOS 1502/1601 .. the problem width Audio somehow disappeared for now or maybe the emitting component in my circuits. However i wasn’t happy with the digital to analog converter since it requires additional power supply and using usb power insead of power supply was a bad choice since the emitted frequencies i had earlier were injected in that converter too.

 

 

Asus x99 Deluxe BIOS Ver. 1305

slight base Vcore increase

So many BIOS Versions have been released by ASUS for the x99 Delux series. What you might experience with 1203 and 1305 is a slight increase of “base voltage” on the Vcore.

When i keep using my old offset values (0.24 V) for the Vcore i do get 1.3 V on that i7-5930K. Pre 1204/1305 i did get 1.28 V.  Thats an increase of 0.2 V just by updating the BIOS.

 

CPU seems to respond better to what you throw at it

What i did also notice is that the CPU does respond, let’s say, more accurately to the frequencies and voltage you put through. It feels more straight.

In the past i could clock the CPU to 4.6 GHz @ 1.3 V and were able to boot and use Windows. That’s no longer possible. I would have to add quite a lot more voltage ontop of it to get it going at these settings.

What did the board achive so far with 1305?

Currently (02. feb. 2015) i am at

 

CPU freq. RAM freq. Uncore freq. CPU Vcore RAM Vcore Uncore
4350 Mhz 3070 MHz 3584 MHz 1.32 V 1.35 V 1.2 V

 

I just started to play with it and will slightly decrease the Vcore. I am still using offset values. Go Offset!

Old sad story – prime95

After all the trouble and questions we had regarding prime95 and Hasswell-E. I decided to run prime95 tests with the Kraken x60 at “silent” and at “custom” mode.  I noticed that Core 0 is behaving quite unimpressed – because the Worker 0 in prime95 stopped stressing the Core for unknown reason. Kraken x60 is a ready-to-use watercooling solution for noobs and lazy people. However as you can see in the bottom box in Kraken Cam, the temperature peaked at almost 90 °C (86 °C) with “silent” configuration.

 

kraken_cam_kraken_x60_asus_x99_1305
BUT: this was NOT a prime95 HEAT test. Keep that in mind. Just ordinary stress test.

 

So i started the prime95 test again due to unknown abstinence of Core 0 and the temperature peaked at 78 – 81  °C.  Fans are NOT at 65%, Kraken CAM is fooling us here.

 

 

LED of your Kraken Heatsink lit up 24/7?

If you want your LED flavoured Kraken/Watercooling Heatsink to not glow when the system is powered off, change the ErP Setting in the BIOS to “S4 + S5”.

I still use Kraken x60 standard Fans. I do want to change those since weeks, or months but never completed this task yet. Maybe you can recommend some.

 

Asus Deluxe BIOS 1004 x99 – Problems solved?

Update 06. November 2014:

One good thing i have to mention is, that i had no problems yet to wake the system from standby-mode nor did i have any problems that occured with BIOS 0904. BUT I went to do the shopping and put my system or tried to put my system into standby-mode, but it never did. This is a strange behaviour.

 

I was talking with a guy “Wei Liu” about these issues and he told me that increasing VTT voltage may help here. He just heard of it or read it somewhere. So i decided to increase voltages. What i didn’t mention yet is, that with BIOS 1004 i tested only with stock-settings the first days. Now when i will run the system oc’ed i’m going to apply the tips. Results coming soon.

 


 

Asus Deluxe BIOS 1004 released in the end of October

I’m currently testing the Asus Deluxe BIOS 1004 they obviously released already in october. I didn’t notice that. However the first 3 tests were successful. Which means the standbymode, that i mentioned in a previous post with BIOS 0904 (and earlier), did work properly with 1004 (… to their Downloadpage)  so far. But the last test is pending. The standby-problem tend to occur, when the system is cold, what indeed is currently not the fact. Even a 10 minuten power-break doesn’t simulate a cold system correctly. I have to wait, then when i wake up the next time to proceed with it.

Asus Deluxe BIOS 1004 - Problems solved?
Asus x99 Deluxe

 

Few words about the previous BIOS 0904

By time passing by, i experienced some other problems with the previous BIOS 0904. Once it happend that the system forgot about the Boot-Settings. Another strange situation came up, when the system started on its own after a clean shutdown.

I will try observ this too for sure on the new BIOS 1004. Or lets say, you can’t ignore these mal-behaviours since your perception can’t elude these.

Nothing solved at this moment. Status is open.

Asus x99 Deluxe standby mode not working properly

Update Jan. 2016

Update 06.11.2014: When using Corsair Power Supplies:

Go to http://www.corsair.com/en/rm-series-rm1000-80-plus-gold-certified-power-supply and click “Haswell compatibility” under the FAQ & Support Tab.

Quote “According to Intel’s presentation at IDF, the new Haswell processors enter a sleep state called C7 that can drop processor power usage as low as 0.05A. Even if the sleeping CPU is the only load on the +12V rail, most power supplies can handle a load this low. The potential problem comes up when there is still a substantial load on the power supply’s non-primary rails (the +3.3V and +5V). If the load on these non-primary rails are above a certain threshold (which varies by PSU), the +12V can go out of spec (voltages greater than +12.6V). If the +12V is out of spec when the motherboard comes out of the sleep state, the PSU’s protection may prevent the PSU from running and will cause the power supply to “latch off”. This will require the user to cycle the power on their power supply using the power switch on the back of the unit.”

Also check out their forums (http://forum.corsair.com/v3/showthread.php?t=118456). Possible that you need a new PSU but at first you could try to disable C7 state (if possible) in your BIOS settings and see if it helps.

 


 

You may know or not that i bought a new system this year. However the Asus x99 Deluxe standby mode seems to confuse some of the components of this system or its the mainboard itself messing around with it.

 

Infinite loop

When i put my system into standby or suspend mode i can’t really wake it from there. When i try to wake it: the hardware responds, fans are starting to spin, harddrives etc, but the system is not really recovering from the standby mode, instead the system goes to Q-CODE bF and sits there until it starts to reboot automatically. Even a 4-sec-press-hold the power button doesn’t help to cold boot the system. The system sure goes down, but it does keep the system to do the bF loop. It keeps infinite (re)booting.

 

Q-CODE: [bF]

 

The first thing i did was CMOS reset but it is NOT necessary!

Instead: turn off your power supply wait a few seconds and turn it on again. Then the system should boot normally.

I already did play with some BIOS settings and there was something strange happening when i enabled ASPM Support in “Advanced->Onboard Device Config->ASPM Support” ….

 

Asus x99 Deluxe standby mode messed up?
Asus x99 Deluxe standby mode messed up?

When i enabled ASPM Support, i was able to put the system in suspend/standby mode and wake it with either keyboard or power button, right on the first attempt. This made me think i found a solution. It did work 3 times in a row. I then wanted to know if i can reprocude this by undoing the changes to see the bF code again and redoing the changes to see a working standby mode, and failed. Disabling and reenabling ASPM Support didn’t come up with a working suspend/standby mode.

 

 Asus Technical Support

I already wrote to Asus Technical Support and the first “conclusion” was, that i may have defect hardware with the aim at power supply.

 

Do you have same or similar problems? Different Q-CODE? Let me know!!

 

Update: Well sometimes its working and sometimes not. And when i try to record it with a camera, take a guess, its working…. to be continued

 

Asus x99 Deluxe, i7-5930K overclock – don’t use prime95 on Haswell-E and 2011-v3

Update: 12. March 2015

This post becomes old, however, even when it may have been stupid to call prime95 a bad choice to test overclocks it somehow may have saved peoples wallet. In the beginning when x99 was thrown onto the market, things were very new and everyone had to get closer to the new design step by step, carefully. As you have to admit, there were many articles about mainboards that were catching fire, go up in smoke, or break in any other possible way. Things are getting more stable and people are making their  way through the jungle of architechture. Today i still would recommend people to be careful with prime95 but i would no longer discourage people from using it.

Update: 06. October 2014

Well i can not completely revise this.. when i started to think that prime95 doesn’t go well with Haswell-E i did run future tests with other tools like cinebench, sisoftware sandra, aida64 and had no problems even with lower voltages (1.28 V). Rendering videos, playing games and whatever you do with your computer also did work quite well. Today i tested with OCCT and it goes the same direction (1.35 V stable).  With prime95 i ended at 1.37 V or even 1.39 V . So prime95 still does require lot more voltage to run stable than for example OCCT does, so im not sure yet where this journey is gonna end. I can not recommend using prime95.

 

Hellow peeps. The long journey comes to an end now. [Due to Update on 06. October i have to  over-think this] I finally or accidently came to the “conclusion” that prime95 isn’t the right choice to test the Haswell-E processor series, like the i7-5930K to run any sort of stresstests.

In the end of the day this processor, the i7-5930K will be running at 4.5 Ghz  with everything else overclocked at reasonable temperatures and stable. Well, not prime95-stable but Aida64-Cinebench-and-SiSoftware-Sandra-stable. Prime is just no longer an option or relevant for 2011 and x99.

 

So this is going to be a big round-up confusing

The truth is, that i stumbled over a forum thread, while i was searching for wprime95, saying that prime95 doesn’t go well with Haswell-E. So, while it’s still saturday night/sunday in the very morning and i was about to leave the system for today as it is, i decided to repeat some steps on the Asus x99 Deluxe, i did in the past weeks. In the beginning of the OC-adventure, i started with prime95 only and later took SiSoftware Sandra into the boat.

 

Quick Overview of the System (or have a quick look at previous posts):

  • Asus X99 Deluxe (white/black) Motherboard
  • Intel i7-5930K  at 3.5 GHz (will use MX-4 paste)
  • Corsair Vengeance LPX DDR4, 16 GB, 2800MHz  4-Modules-Memory-Kit
  • Corsair RM1000 Power Supply
  • Kraken X60 Watercooling
  • 4x Corsair 140mm Fans (purple/violet)
  • Corsair Obsidian 450D Case

 

 

Replacing prime95

Now prime95 has been replaced by Aida64 and Cinebench, while SiSoftware Sandra stays in the club. Benchmarks and graphs are always nice, but i intentionally use the software to make sure components are working fine together in harmony.

It’s already a month now since x99 and friends have been thrown on the market. A lot of you guys were sure smarter than i am/was and already knew that prime95 is a bad idea – when it comes to Haswell-E. While the hole world already OC’ed their CPUs with success i will just stick to some pictures. After i decided to no longer use prime95, i  revoked / undid most of the changes i made there, to start from zero.

4,5 @ 1,37 – 1,39 V prime95 stable, requires extreme² cooling 128,7 (BIOS 0904)

Some values were tested on different BIOS versions, some were stable some were not, some or many of them don’t even show up here. The table doesn’t show all  combinations. In all cases you can say, that the newer setting also did run at least 1 BIOS version behind. For example 4.5 GHz was also tested on 0801 with Vcore from 1.27 to 1.390  and a lot of changes in voltages for other parts like Input Voltage or Agent Voltage or Cache Voltage or Changes in the DIGI Tab. But i do not recommend this especially because this happend in the prime95 period. In a previous post i said that XMP with BIOS 0701 was unstable. Thats not correct. This was also affected by prime95.

To the edge 4.6 GHz but prime95

As i mentioned already in a previous post, i could easily clock that Haswell-E jewel to 4.6 GHz. Problem had been, that it just didn’t pass the prime95 tests and that i found myself increasing and increasing over and over again the Vcore. At this moment i was noticing something weird with prime95 the first time, but i didn’t know about that bad relationship between prime95 and Haswell before, so i kept using it. What in the end led to a super hot CPU and with a crying Kraken X60 with stock fans. I made a short clip to demonstrate the Kraken stock fans at 1000% load (yes, that extra zero was intended).

On 30. Sept. 2014 (2 days after publishing this post) - got a bluescreen 0x3B occasionally  during SiSoftware Sandra Multicore Efficiency Test (this test did already run a few times with no error or bluescreen); will increase Vcore slightly from 1.276 to 1.29. This update doesn't show up in the BIOS screenshots below!!!

 

Now starting from zero with default settings and new crew

So starting from zero with some basic settings (CPU, DRAM, Cache and Baseclock will be set), and some of them are the result of the past few weeks. Initially will reset all voltage values and any performance related values to “Auto”  again and boot the system.

Not that surprising but defaults deliver

And find myself happy with it. Now where the Vcore is back to normal and due to the absence of prime95 the temperatures during stress tests are lovely ( the funny thing here is, they never were bad, just prime95 made appear everything worse ). And more important the Kraken X60 stock fans do not  have to go crazy anymore. Win-Win situation for me and the computer parts. Maybe i can get back to my Corsairs purple fans? When i run prime95 now with these settings, the system instantly goes down, but on the other hand i can normally use it. Can run any (non-prime95)benchmark, can render videos etc, can play any game … etc. somethign weird is burrowed in prime95.

SiSoftware Sandra Lite i7-5930K benchmark

Overclock with no bluescreen is no serious overclock

Now, 2 weeks after purchasing this new RIG i went a step forward and decided to consult SiSoftware Sandra Lite to get some more details and i7-5930K benchmark. After playing with it in the first 1-2 hours i got the 5th bluescreen during the overclocking evolution period, which may hopefully end today. I received my 5th bluescreen during SiSoftware Sandra tests/Benchmarks. You may have a look at the Hardware / Computer section for upcoming posts and updates.

 

Quick Overview of the System (or have a quick look at previous posts):

  • Asus X99 Deluxe (white/black) Motherboard
  • Intel i7-5930K  at 3.5 GHz (will use MX-4 paste)
  • Corsair Vengeance LPX DDR4, 16 GB, 2800MHz  4-Modules-Memory-Kit
  • Corsair RM1000 Power Supply
  • Kraken X60 Watercooling
  • 4x Corsair 140mm Fans (purple/violet)
  • Corsair Obsidian 450D Case

 

History settings

History settings (i will skip experiments that weren’t tested in longterm view, for example playing with Vcore for the CPU or when i switched back to basic settings when trying to figure things out/ bluescreens) from oldest -> to newest Setting(s):

 

CPU i7-5930K (including Turbo)in GHz: Corsair LPX DDR4 RAM in MHz: Asus x99 Deluxe Baseclock in MHz:
3,7 @ base values, unknown voltage (release BIOS 0505) 2166 @ base values, unknown voltage (release BIOS 0505) 100 @ base (BIOS 0505)

4,425 + 4,5 @ 1,276 V (BIOS 0904) 3088 @ 1.35 V 128,7 (BIOS 0904)

These current settings values (antepenultimate row) are valid until 26. September 2014 – for further information please read this post (most recent at this moment) or  this one. The penultimate row in the table are values tested after publishing this post. Final or most recent settings you can find in the most recent link above. Some values were tested on different BIOS versions, some were stable some were not. The table doesn’t show all these combinations. In all cases you can say, that the newer setting also did run at BIOS version 1 behind. For example 4.5 GHz was also tested on 0801.

 

The i7-5930K benchmark

Update 28. September 2014: Unfortunately i didn't write down the PW for SiSoftware Ranker. The links now point to the new account.

With a baseclock slightly decreased from 127.5 to 125 MHz and RAM voltage, now again, at 1.35 V – but this time with 3000 MHz clockspeed – i hope to get closer to a smooth running System. Check it out directly: SiSoftware Sandra Ranking Page of tatoismus.net >>

This one has a better overview: Another Ranking Page of SiSoftware

After these little changes were made, all tests did pass with no further problems. The screenshots show the rank from 15. Sept. to 16. Sept 2014. Ranked #123. (Just 8 hours later im ranked #326 🙂 they’re all cheating)

Cooling the i7-5930K

Additionally i installed a 120mm fan in the rear of the case just to get the warm air a little bit faster out. When i was facing 90 °C and more in the past at full load with the 127.5 baseclock setup, i now still reach 90 °C and more but it takes a tiny bit longer to get there 😉

Just to make sure: temperature was never the issue, i was always monitoring temps when i did any sort/kind of benchmarks. During benchmarks the CPU cores sure get to their limits but never on a timeperiod long enough cause any heatdamage or impact results or cause bluescreens. Well, i talk about SiSoftware Sandra. — Armed with prime95, things become different.

 

Sorry Sandra

Few words about Sandra SiSoftware. I hate it. Or lets say it was frustrating me in the beginning. Its okay for a wide range of tests, but i will never use it again i think, untill my computer produces another bluescreen.

I can haz user account?

You have to run it as admin. I mean you have to login as admin. “Run as Admin” isn’t enough. And then you can/are able connect to “Local Computer”. Don’t ask how you can upload results to their Ranking-Website using a specific username. I managed it but it hurts explaining it. In the end it is simple but i expect things do work different. You don’t register or create an account in a way you would expect. You simple put a name and email address and password in the fields and fires return key until a picked account name is being accepted. Not talking about the bad named and bad placed module “Top Results”. Who expects that you enter your account information in here? And why locate it in Benchmarks? And you should really not use their FAQ or you will find yourself smashing your head on the desk.

 

ram3000

 

Recognize my RAM correctly pls

By the way: SiSoftware Sandra doesn’t know that my RAM is running at 3000 MHz. It always says for whatever reason “2133 MHz”. You have to look at DRAM Frequency and multiply it by 2 “DDR = Double Data Rate”. Seems that Sandra is only reading some vendor model strings and thats it.

 

bahuett

Another challenge for Corsairs DDR4, i7-5930K and Kraken x60 – new BIOS 0801 for Asus x99 Deluxe

Almost a week now since i purchased all the good new parts for my new computer. A few days now playing with overclocking (OC) parameters. Yesterday my computer froze two times and i had to start figuring things out again. You may know from my previous post, that i had to run the DDR4 RAM Corsair Vengeance LPX 2800 MHz at 1.35 V because i was experiencing issues and that the CPU i7-5930K was clocked at 4.1 GHz which was fine so far. The root cause for the system hangs is unknown yet. Could’ve been either CPU or RAM. The baseclock hadn’t been touched since today in the morning.

 

Sorry guys, i’m not going to show you lots of graphs of games and benchmarks.
But i can offer a link to SiSoftware Sandra results.
Little update 26. September: 4.5 GHz achieved. Video clip soon. Scroll down for more information.

 

Well, the first things i tend to do was adjusting DRAM voltage and set CPU back to its basic settings. That worked so far with little throwbacks – if i remember correctly – but even than that i decided to check Asus webpage for new BIOSes for the Asus x99 Deluxe and there it is.

X99-DELUXE BIOS 0801 

 

Seen, downloaded, installed.

And suddenly the XMP profiles did work pretty well with my DDR4 RAM. But there was a downside. The baseclock got raised to 127.5 MHz and the CPU received a slight voltage bonus and runs at 1.250 V now. (In the following picture the CPU runs at 4.2 GHz which was not the fact today in the morning).

 

CPU-Z: i7-5930K at 4.2 GHz and 1.25 V and 127.5 baseclock
CPU-Z: i7-5930K at 4.2 GHz and 1.25 V and 127.5 baseclock

 

That’s what was happening last night till today morning. I also made the first steps towards temperature enhancements. But failed. I set the CPU voltage to 1.110 V and hoped it would be enough to run the CPU smoothly and be able too cool it down. Negative Houston. Not stable enough for prime95. The overclock-process continues. When i came home from work today in the night (now) i proceeded the work on this. I configured the XMP profile and made no changes to the CPU voltage but i added 1 step to the ratio, means 4.2 GHz for the CPU.

Remember i donated a watercooling system to my computer. The Kraken X60. The Corsair fans i installed in place of the Kraken fans are not made to handle so much heat – it seems. The temperature hits the 92 ° C  mark. Not good at all.

 

i7-5930K at 4.2 GHz and 90 ° C
i7-5930K at 4.2 GHz and 90 ° C

 

There is at this moment no way i can enhance the cooling yet if i want to stick to my purple fans. Two fans are covering the radiator and if i would go quadro-fan i had to buy a new case or install the radiator in the fron which in turn would mean good-bye 3.5″ inch harddrives.

I started prime95 right before i started to write this post and it did accompany the hole time. The result now is, that the CPU and RAM seem to work stable but the temperature is really an issue here. I have to point out that the problem with the temperature occurs with the increase of the baseclock. I had no problems yesterday when the baseclock was at 100 MHz.

Now i could:

  • buy another case and install 4 fans on that radiator and leave it installed in the top
  • install 4 fans on that radiator an move it to the front of the case and lose 3.5 inch harddrives
  • remove the purple fans and try the Kraken fans or any other fans which cool better and have to chose between decibels and efficiency and leave it in the top of the case without losing harddrives
  • compare the cooling system to other cooling systems and buy a new one or directly start with a custom water cooling system
  • or  put the baseclock back to 100 and see if i can get it stable without XMP
  • or reset to basic factory default settings … what? who did say that?

 

 

SiSoftware Sandra Benchmarks with Intel i7-5930K

 

Three weeks later and with an Intel i7-5930K at 4.375 GHz i still am juggling with temperatures. Even when running the Kraken X60 at full speeds, the temperature hits 91 °C during the prime95 stress test. I didn’t change anything yet but my first attempt, my first step will  be to install the Kraken fans in place of the Corsairs. Will update this post today once again.

 

cpu-z i7 5930k at 4.375 GHz
CPU-Z: i7-5930k at 4.375 GHz

 

Ok today (26. September 2014) i installed the Kraken fans

which come with the Kraken x60. The results are much better. The fans tho, are noisy as fuck but i can get things straight now. I also managed to weak the i7-5930K at 4.5 GHz with a vcore of 1.390 V. The temperature almost instantly raised to 95°C when running heat-tests with prime95. With the fans at fulls-peed this is really the limit. Just when graphics card would kick in, or something else that generates more heat in the sytem, i’m pretty much fucked. So when you were looking for a review of Kraken X60 and i7-5930K i can tell you that you might achieve those 4.5 GHz with that Kraken X60 water-cooling-set but you will not be happy with it. I will try some other fans in the near future. I spent a lot of time at work to compare fans, their pressure and throughput etc.

 

4.5 GHz achieved

temperatures > 90 °C (with prime95 heat-test  and Kraken fans at 100%). Regarding prime95 and current settings (after publishing this post) please read this post, important!

 

I made a short clip of the system when running at 4.5 GHz to capture the noise too. It was a very important step and lucky me, the right one to get my temperature problems solved and detect what the problem relies on.

Well, since i reached the limit of my current built i will go back to 4.375 GHz where temperatures and water-cooling run smoother. When running a heat-test the temperature does not hit the 90 °C mark and fans are not going crazy.

 

 

5930k_4.375ghz1.29
CPU-Z: i7-5930k at 4.375 GHz [1.290 V]

As soon as the Vcore, preselected by the mainboard, does not lead to a stable system, you are in that performance spectrum of the CPU, where you 1. start to lose Performance/Watt 2. and have to add some extra Volts on the preselected value to make it stable.

It turned out that when i want to run my system at these 4.375 GHz, i add 0.01 – 0.02 extra Volts to it (preselect value 1.27 sometimes 1.28) and will end up with a Vcore of 1.29 . Obviously i did not get the first price in the silicon valley lottery but it could be worse and with only 0.01 extra Volts i’m very close to the stable region of that die. However, the preselected Vcore value at 4.5 GHz was 1.310 Volts. I had to add 0.07 Volts to make it run stable. Hot, but stable. That does also mean that for 1 extra ratio / multiplier i have to add almost three times as much Volts to the preselect value as i have to when running at 4.375 GHz.

 

 

 

I definetly will get some other fans but for now they do their job pretty well. To be continued.
