CPU overclock causes GPU to crash 0x116

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 when my cpu is overclocked, 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!
 
Well I have no experience OCing any Haswell, but perhaps there's the "PCI-E lock" option that you might have forgotten to enable? that if you've raised the BCLK of course.

Other than that it's possible that your OC is really not stable, you can get 0 errors from many stress test utilities for 24+ hours straight, still those tests don't get to cover all of what the CPU has to handle, see if with a lower OC you get to work it stable.
 
Far as I seen by the posts by others whom OC, you basically found the 'ceiling' and you should go back in increments of .1 till you can reliably keep the GPU from crashing the system. Otherwise I would look at running Slim Drivers just to make sure I have the latest drivers on everything. Personally it sounds like the demands from the GPUs when interacting with the OC CPU pushes it that .01percent over that 'stable' threshhold you originally established.

I've only raised the multiplier so Bclk is noy an issue and that also seems strange to me. I thought 4.2 could be easily reached and i might have the qorat luck if that is my ceiling. I might try even lower but that kind of beats the purpose when the boost clock is already at 3.9ghz. :(
