Yours could be the same, flashing bios is quick and painless these days. Gigabytes website should have step by step instructions and the latest bios for your board.
1.25v QPI and 1.65v DRAM won't do the trick. Video driver started to crash and finally operating system went down (freeze without BSOD).

I'm pissed off, but I'll work without C3/C6 power options. No chance with this motherboard.

Just because I want to retain stability at Turbo PerfLevel+1T CR memory settings I will return to 1.62v DRAM (1.6 is GB default) and 1.21 QPI.

I'll overclock this CPU a bit to compensate

I noticed with 1156 the i7's need more qpi/vtt voltage then the i3's. It might have something to do with the difference in architecture. The 32nm i3 has a better imc than the 45nm i7.

As far as qpi/vtt voltage with the i7, I noticed if you have 2 gpus it will need an substantial increase in qpi/vtt voltage with any overclock. The i3 on the other hand can overclock like crazy with barely any qpi/vtt voltage bump. Not 100% sure why this is.

When I had my two 1156 rigs I only used prime95 for stability testing. And generally speaking, while stress testing, a bsod would usually mean qpi/vtt bump is needed. While a worker thread stopping or any other p95 error usually indicated vcore bump was needed. Funny, because with sandy bridge it is the exact oposite. Sandy bridge: bsod (124,or 101) means vcore bump is needed, and errors in p95 means unstable memory timings/memory overclock, or vccio (qpi) bump is needed.

Just when you get used to something Intel flips it around and upside down.

edit: op btw, gigabyte p55 board have known issues with intel turbo feature. I had the hardest time getting turbo to work properly on my p55-usb3. Ended up getting an evga p55-sli-ftw, and it gave me no problems what so ever.

try running linx, or prime95. If you get no errors or bsod, then you have a software/driver/os problem and a clean install of windows may be necessary.

THank you for your response.

In my case, as long as I stay away from C3/C6 Enabled, the system is flawless. So I'm with 22X/24X TurboBoost only (up to 27X with C6 enabled).

I don't think it's related to QPI/VTT for *stock* memory and CPU frequencies.

Later I will put an old PCIe NVIDIA 7300GT and see if the video card is failing with the C3/C6 power state, because the amdkmdap ATI driver fails frequently after some usage.

It's strange that I can play e.g: 1 or 1 1/2 h of Fallout 3 or intense 3DMark11 benchmarking and after that the video card starts to fail until a complete freeze arrives.

May be it's temp related? I've monitored up to 75ºC in Fallout 3 and 87ºC in Furmark.

However, the strange thing is that it worked 100% the the i3 and works 100% with the i7 WITHOUT C3/c6 enabled.

Also, I don't think the CPU is failing, because reaches all it's power states OK with C3/C6, but I will test with the other old card and tell the results.

If it works, maybe it's some related to C3/C6 states and PCIe controller???

Again, thanks for help!

After you clear cmos what do the voltages default to? Vtt, vcore, dram and so on and so forth. Also detailed system specs. This is like throwing darts blindfolded right now.

Reset cmos load optimal defaults and then post the voltages is sets you too. From the looks thats 1.5v ram.... Also what gpu and such.

I'm currently testing a 3.66GHz Turbo-Off overclock to overcome the lack of 27X turbomultiplier (I run single / double-thread old apps, I dont want to lose the benefits of C3-C6 states off).

2 hours of Prime95 no problems. Needs more testing, but goes well.

66ºC max CPU temp.

Anyway, back to your question:


With CMOS Reset, all is set to AUTO as follows:

VCore: 1.235V [Auto]
VDDR: 1.600V [Auto]
QPI: 1.1V [Auto]

My current settings.

VCore: 1.25 (this is "Normal" setting in GB)
Dynamic DVID: +/- 0
QPI: 1.21V
VDDR: 1.63V

GPU is ATI XFX 5770, stock clocks.

**EDIT**: Crashed video again with 0x116 BSOD C3/C6 disabled but under 3.66GHz CPU clock. Low VCore/QPI??

Your ram is 1.5v ram. Just saying. I would give up on doing prime. Download and make a memtest86 boot cd and run it. Im going with your ram is bad.... That or you may need to manually set your timings, some ram is picky about that. Either way you have a bad piece of hardware somewhere. If it passes memtest then its either cpu or gpu, gotta narrow it down....
