i7-2600k and Gigabyte Z77X-UD5H Overclocking issue

post #1 of 15
Thread Starter 
Hey guys,

I'm a new member and recently joined overclock.net because I am seeking some advice/assistance with the problem I'm having Overclocking my i7 2600K with my gigabyte Z77X-UD5H Motherboard. Now before I start I hope I am not posting this in the wrong sub forum so I apologize ahead of time.

My system spec:
  • CPU: i7-2600K
  • Memory: 2x 4GB Corsair Vengeance 4GB DDR3 1600Mhz Ram 9-9-9-24 = 8GB
  • GPU: 2x EVGA GTX 780 In SLI which is 2x8 PCI Bus speed with sandy bridge.
  • Motherboard : Gigabyte Z77X-UD5H (Rev 1.0) F14 BIOS and F15q Beta BIOS.
  • PSU: Corsair AX760i


So recently I started to overclock my CPU above the default Intel Turbo which automatically pushs the clock to something around 3.8Ghz with x38 multiplier, at first I just wanted to achieve anything as little as a 4.3Ghz overclock so I don't have to increase the vcore so much, so I simply increased the multiplier and left the vcore to around 1.250, changed the vcore Load Line Calibration to like High/Extreme so I don't get Voltage dropping during Max Load test and using Prime95 for about 4/5 hours everything worked fine with out any issues what so ever. However the problem lies when I turn my computer off for a while or from the PSU power button, the next time I turn it back on the BIOS fails to post. So the PC turns on for about 6/7 seconds then shuts down and repeats this a few times until it finely posts enters BIOS with an error message "Boot failure possibly due to some BIOS settings being incorrect"

Now I have tried so much to find out what could be causing this, I disabled X.M.P profiles for my RAM and lowered the speed to 1333Mhz, Manually set the RAM timings, increased the DRAM voltage to a tiny bit, changed BCLK speed manually to around 100.05 or 100.10, increased & decrease the vcore basically no matter what I tried to do I have this issue and its very random. Like some times I can turn my PC off and turn it back on and it will post normally but some times it just fails to post and it shuts it self down a few times and finely boots to BIOS with the above error message.

Otherwise right now is running with everything on auto and turbo and it works fine with out any issues what so ever like it has been normally. I just can't figure out what the problem could be I even tried to use the latest BETA BIOS the F15q which only made minor changes and that didn't resolve my problem, funny thing is everything is stable and fine in windows its just this random BIOS error/post problem which prevents me from overclocking.

I was even considering to sell my components and go for a Haswell 4770K and a new motherboard at some point but I thought I might ask around a bit perhaps some one else had the same issue and found a solution.

P.S I forgot to mention that i also have all the power saving feature disabled in the BIOS when I was attempting to overclock.

Thanks in advanced!

I think your power supply may be insufficient, I wouldn't be comfortable with less than a 1000w power supply if I was going to overclock your. Setup.

Yeah I understand what your saying however I have managed to overclock and run Prime95 with out any issues, the problem here is when motherboard fails to post and during that time the system is not at Max load anyway. A 1000W PSU is overkill for my needs in my opinion because I know my system would never come close to using that much power.

I agree that my Corsair AX760i Might be cutting a bit close but I have ran stress test for GPU + CPU at the same time and had no problem at all, so I really doubt the specific issue I am having is PSU related.

That is ludicrous. I had a 780 sli 3770k rig fully watercooled overclock to the max with a 860w.

OP there are guides on here for your cpu just take a look around.

i was having that issue with the latest beta BIOS'es
Flash back to the latest certified one
Do not use BETA's!!
I would start up my pc and it would restart from 3-15 times until it booted.
Hope it helps

Thanks mate I will have a look, but while I got your attention could you kindly confirm something for me, If I were to buy a 4770k and a New motherboard like the gigabyte Z87X-UD4H or even the UD5H (the new Socket 1150 ones) My PSU would be sufficient enough right? Because I just used http://www.extreme.outervision.com/PSUEngine and with everything at 100% Max load with 4770K overclocked to 4.3Ghz it reports about 718W. Considering that hardware generally isn't at 100% maxload all the time I think my PSU should be more then enough.

I ask this because I purchased this PSU not too long ago and it wasn't cheap, so I really rather not buy another one for no reason.

Sorry for double post, can i ask what BIOS version you currently use? I am using F14 at the moment, because this motherboard has dual BIOS so one of them is F15q and one is F14.
