Sometimes all cores are at 77C for a while and sometimes 82C, apparently they even hit 86C once. Anyone got an idea why these temperatures fluctuate like that?

your temperatures will fluctuate based on what round of stress testing you are doing, in 15 minute intervals if you are using stock settings. P95 starts with the largest fft for the first test (0-15 minutes) and moves to the smallest right after (15-30 minutes). From my observation, the second test (8k fft) produces the most heat. It is not always the one that will produce a BSOD or rounding error, but it is most certainly the hottest.

Ah I see, that is indeed the period in which temperatures change. Thank you.

Is there some way to disable the onboard video on the z77e4?

Want to troubleshoot my 550 TI but every time it fails the PC continues to post using the onboard card.

I dont know of a way to completely disable it in BIOS, only to set the PCIE as primary, which it appears you have already done.

Go to advanced/northbridge and look for igpu/multi monitor support and disable. Should turn off the onboard video and use your 550 ti.

Also make sure that PCI/PEG and not PEG/PCI is the default setting.

Apologies I may have confused my AsRock and Asus boards all together. What you need to do for the Asrock is go to Advanced\North Bridge Configuration and make sure to select PCI Express as the default choice for Primary Graphics adaptor.

You should also disable IGPU Multi Monitor, Render Standby and Deep Render Standby.Those 3 should all be below where the Primary Graphic Adaptor option is.

HERE is a screenshot of what it looks like (It's for the Extreme 6 but it should be the same)

Having trouble OCing my i7-2600k on an ASRock z77 Extreme4-m past 4 GHz. I figured I would get to 4.4 GHz easy with 1.4 VCore max.

I ran it at 4.2, 4.3, and 4.4 GHz with CPU LLC @50%, VCore @ 1.4, and they all failed. All other voltage settings are on Auto.

I followed all the instructions. Disabled SS, PLL overvoltage, Maxed power limits, Disabled Power Saving, and the bottom 3 C-States.

The funny part is that I noticed that my CPU would throttle while @4.4 GHz OC while prime was running prior to it crashing. I would noticed temps would drop and the chip would go back to 3.4GHz. This was all at 72 celcius. I didn't think it would throttle this early. Or maybe the MoBo is throttling the chip.

Any help would be immensely appreciated.

Passed the final test and over with 4,5GHz, Vcore offset +0,010V and Turbo offset +0,012V. Hottest core with the final test still in the background is max. 73 degrees.

I tried 4,6GHz but I got a BSOD about bad ram, ran the mem. diagnostic tool and it came back clean. Tried increasing the voltages but windows explorer crashed.

Any clues on why it started ~randomly crashing at 4,6? My temps could be 7-10 degrees more taken into consideration that I get enough speed from those degrees.
