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
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.
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.
Powersavings were introduced back in the 90 at the end of the last century and there is no reason anymore to not make use of it, even when overclocking. These days SpeedStep or PowerNow technology could cause several stability problems but today we are facing software and hardware which has improved significantly. Go Offset! Time to make a change, time to make a cut here and use it. Only when using offset mode the processor can apply its power saving steps ontop of it. Maybe in the future they will be able to scale.
It’s nothing of a big deal
Just go into your BIOS and switch from fixed value to offset mode. You just have to do the math. Get the base voltage of your CPU and add that extra voltage you already applied in your fixed voltage and add the difference as offset voltage.
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.
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.
CPU i7-5930K in GHz:
Corsair LPX DDR4 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)
2800 @ 1.5 V or 1.35 V (XMP didn’t work and Memory was very unstable at higher frequencies – or let’s say, with prime95 it was)
4,1 @ 1,23 V (release BIOS to BIOS 0801)
2800 @ 1.35 V (release BIOS + BIOS 0701, XMP started to work with 0701)
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). [Video quick link].
CPU – i7-5930K
DRAM – Corsair LPX 2800 DDR4
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.
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)
2800 @ 1.2 V (BIOS 0701 + 0801, XMP values started to work with 0801, 0701 was still unstable)
127,5 (BIOS 0801)
4,25 @ 1,25 V (BIOS 0801) – current
3000 @ 1.35 V (BIOS 0801) – current
125 (BIOS 0801) – current
4,375 @ 1,265 V (BIOS 0801)
3000 @ 1.35 V (BIOS 0801)
125 (BIOS 0801)
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 >>
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.
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.
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.
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).
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.
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?
Three weeks later and with an Intel i7-5930K at 4.375GHz 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.
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.
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.
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.
