Hey,
I’m a new owner of the following build:
Fractal R4 Pearl
Asus Maximus VI Hero
Intel 4770k with Corsair H100i
G.Skill TridentX 16GB 2400mhz CL10
2x XFX 280x DD
Samsung 840EVO 120GB
Corsair RM1000W
I have tested to system to be stable under stock values with XMP turned on. I tested this via Aida64 Stability Test which Is kind of stressful and runs all parts at full power, for a few hours. I also ran Prime95 Blend and Small FFTs for a few hours and Unigine bench for around 6 hours. Now, I always overclock my system and this one is no exception.
I looked through various sources that had guides for Haswell and particularly 4770k overclocking. I was able to reach 4.4ghz and 4.5ghz with ease and boot up to windows. I achieved these with 1.25vcore. I ran Aida64 and Prime95 Small FFTs for an hour for both of these without issues.
However when I try to use anything GPU related, the computer crashes. It can be as small thing as starting up GPU-z to check on temps. The system ALWAYS crashes with atikmpag.sys and error code 0x00000116. I tried upping the vcore as high as 1.35, but the same thing still happened. I also tried to up the PCH voltage, Cache voltage and CPU Input Voltage, of course by small amounts and checking the amounts on guides. I also tried the CPU Level UP which is available in the Hero Bios. I'm kind of stumped here on how to get my overclock stable on 4.4 - 4.5ghz. I can provide minidumps if they help to solve the issue.
Also I only had time to briefly test the AiTuner, but when I overclocked the computer to 4.4ghz through it, I was able to run GPU-z without a crash. When I go to bios and set the exactly same settings there as in AiTuner, the computer crashes when running GPU-Z.
My overclock settings have been as follows: BCLK 100, Multiplier 44-45, CPU Cache speed on Auto (3900Mhz), Vcore 1.25 - 1.35 (Also tried adaptive with 0.05). All the other options basically untouched, with maybe small adaptive on cache, agent and pch.
Thanks for your help guys!
