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” ….

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

 

When Overclocking: Use offset voltage over fixed voltage

Today i decided to get back to powersavings and changed my fixed cpu core voltage to an offset value. The reason is pretty simple: I want the voltage to reflect the current core speed or in other words, to supply the CPU with only the amount of voltage it actually needs. On the one hand to give the CPU a break when possible, when no performance is needed and maybe extend its life time and on the other hand to save energy. It’s there, you can use it! Don’t fear it!

I won’t say: Go Green! – Go Offset voltage!

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.

 

Offset Tweaking Example
My base voltage is 1.040
My target / overclocking voltage is 1.280
So i provide an offset voltage of 0.24

Kraken X60 Software – Kraken CAM vs Kraken Controls

Well, i’m using Kraken X60 water cooling system in my current 2011-v3 RIG with all that shiny stuff launched in september 2014, but initially i did use the “Kraken Controls” Software to configure and adjust my water cooling system.

When i installed the hardware and Kraken Controls these days, they had another software available to manage your cooling system. It’s called “CAM” or “Kraken CAM” and was at version 1.1.2, if i remember correctly.

 

Kraken LED when system powered off

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”.

 

Kraken CAM version 1.1.2 to 1.1.7

However the Kraken CAM version that was available didn’t work well with my new Intel i7-5930K and the Asus x99 Deluxe motherboard. The CPU temperature  couldn’t be read by the  software, like it can’t be read by Kraken Controls (see picture above: no CPU temperature) and the overall look and feel did remind me too much of Windows 8.x. So i sticked to Kraken Controls only and kept using it. Now, a month later, i gave it another try. The version of Kraken CAM is currently 1.1.7 and the CPU temperature is now being read by the software (picture below).

CPU temperature display not the only improvement?

The Kraken CAM software takes way more time to start than the Kraken Controls, which is a downside, but this will not be the point here. What i noticed first was, that it seeeeems to make my water cooling system run a lot smoother or lets say fluent :).  The fans do not spin up that much like they did before at almost equal temperatures results. Yes, there will be a difference in the fan curves between Controls and CAM, but the point are the temperatures. That can only mean, that the pump is being used more efficiently.

 

Chose Kraken CAM

No matter what they did here, i  write this post to just recommend you using the Kraken CAM software instead of Kraken Controls! I also doubt that they will put further development on the Kraken Controls software.

GTX 770 and World of Tanks performance issues gone in 9.3?

In a previous post i was talking a bit of my problem with my EVGA GTX 770 and World of Tanks.

Today, after a couple of weeks of abstinence, when playing World of Tanks, which is now at version 9.3,  i do notice an enhancement with GTX 770 and World of Tanks but i can’t really tell why. Few days ago, NVIDIA released a new Driver Package especially for the new GTX 9 series. In World of Tanks 9.2 i could not notice any enhancements with this new driver. Today with World of Tanks 9.3 i noticed a great frame per second increase. Now you could say, the improvements have been made in  World of Tanks 9.3.

 

Hardware – no improvement after upgrading

I bought the EVGA GTX 770 like 2 or 3 months ago. These days i still had my i7-920 running at 2.66 GHz and some of the old DDR3 RAM at unreasonable frequency. Unfortunately i could not overclock these parts because of the OEM motherboard and BIOS they were mounted on. The idea of upgrading or purchasing a better board for this old components (sad but true, after 6 years these are OLD) was discarded. So i even took the hardware into account when dealing with the “World of Tanks” problem. On september 2nd i did a hardware overall refresh and could then tell: “Nope, its not a hardware problem”. The new i7-5930K and an Asus 2011-v3 board now rock the house. Just search for the CPU and you’ll find some more posts of it, even the overclocking journey.

 

Load – GTX 770 was not running at its full potential

Unlike in previous versions and drivers, my GPU now does hit the 100% load mark, which was not the case in the past and which was the actual problem. The GPU couldn’t perform to its limits, leaving the game running at 30-50 frame per second (FPS). EVGA has its own overclocking and monitoring tools like Precision X and OC Scanner, google for it or visit their website. To let you guys know what i mean here a screenshot: In the top left corner you can now see almost 80 (78) FPS at high resolution 1920 x 1080 and highest settings and 100% render level, which was between 30 and 50 before 9.3.

 

GTX 770 and World of Tanks 9.3 current framerate
GTX 770 and World of Tanks 9.3 current framerate 80 FPS (+- 10)

 

Framerate increased, what an improvement! But?

However i still do notice that the graphics cards load is bouncing sometimes. You could say this hapens because the area where the camera is pointing to requires less performance to get rendered. That would be true if the FPS is stable and take a guess – it’s not.

 

Who needs more than 30 or even 60 FPS at all?

80 FPS is a good rate i can live with for now. The main purpose of these is to make video capturing more comfortable and less eye bleeding when you watch the results. Recording today easily results in a 20-30 FPS drop, if you have no extra performance. If you run 2 graphics cards and limits the FPS to 60 you would’ve had an incredible amount of performance left for recording and other stuff. Now when i limit the FPS to 60, i have only the performance left that encloses or fills the gap between 60 FPS and 80 FPS.

 

GTX 770 and World of Tanks, save to get a 770 now?

Well, after spending thousands of €uros for new hardware and doing upgrades and updates i’m looking forward for future updates. Thank you Wargaming, it was about time.

The GTX 770 is not the best card on the market but its still a good one. With a bit of tweaking you can get her close to a GTX 780 or even a GTX 770 TI at their base settings and clocks.

If you plan to buy a GTX 770, i would say that its save now, when it comes to World of Tanks performance, but i can’t recommend it. The new line of NVIDIAs GTX 9 series made a big step forward in terms of power consumption AND performance. The GTX 770 will perform fine and sexy but you should be aware of that she delivers a higher electricity bill.
