Hi guys,

I'm having a strange issue where my machine keeps crashing but only while playing GTA5.

Yesterday it crashed twice, first time after 10 minutes, second within 5 minutes. Both times in event viewer it logged the WHEA-Logger event 18:

A fatal hardware error has occurred.

Reported by component: Processor Core
Error Source: Machine Check Exception
Error Type: Cache Hierarchy Error
Processor APIC ID: 0

The details view of this entry contains further information.

I done some research and thought it may be due to my overclock so bumped my volts up to 1.2125V from 1.2V I then bench using realbench and ungine and both passed successfully. I also turned off ECO mode on my PSU.

I've come to play again today and I was playing for about an hour and then the screen went black and the fans on my 7850 stopped spinning but the computer stayed on and CPU fans were spinning.

Power cycled my machine and it came up with overclock failed press F1. I've now dropped my OC to 4Ghz but looked in event viewer and this time there is no WHEA event?

Any ideas?
 
So it's just crashed again after another hour of gaming on GTA this time it just went to a grey/black screen with horizontal lines but all fans continued to spin and machine looking fine through window.

Power cycled again and received the overclock failed message but again no WHEA event logged. This time I've reset to optimised default therefore no overclock but can't understand why this has just started happening?

also noticed it's put this in event logs as a warning:

kernel-pnp event ID 219

The driver \Driver\WUDFRd failed to load for the device ACPI\PNP0A0A\2&daba3ff&2.

realbench and unigine are not good stress testers.

play for hours and hours with no overclock and see if it does it. if no, then maybe you should properly test your cpu overclock with prime95 small ftt. and test the memory & IMC with p95 4096k ftt's.
 
Yeah, i've removed my overclock and going to see how I get on.

I'm hoping that it doesn't reoccur whilst at stock otherwise it could actually be a hardware issue as opposed to related to me OC or is that a poor assumption?
 
Well it's just happened again within 10 minutes on stock clocks game crashes and screen goes black/grey with horizontal lines again.

This time after a reboot it logged WHEA-logger in event viewer as mentioned in my original post.

Really confused now :(
 
Just updated the following drivers and still got the same crash within 10 minutes of gaming:

AMD 7850 drivers (crimson)
Chipset drivers
USB drivers

This time 3 WHEA-Logger events were logged :(

Could this be an issue with my GPU or is it more likely related to CPU/Motherboard?
 
it could well be the gpu overheating if youve never removed the dust from it, or just failing. try another modern game or furmark.
 
Will give that a try tonight and see what happens :)

Things I've noted since this started happening are that I've installed a new PSU and also moved my GPU to another slot so I. Going to move it back to the original one and then test BF4 and furmark.
 
Update:

I've moved my GPU back into the top slot (slot 1 i think) and it's just passed an hours worth of furmark.

Going to test BF4 this evening and see how it goes. Fingers crossed that was the cause :)
 
Left Furmark for another hour as didn't have time to play any games and still no issues.

Also ran memtest over night but left all 4 sticks in as to remove them I'd have to take heatsink off.

In 8.5 hours it had completed 1 pass closing in on the second pass but with no errors so think RAM is ok.
 
You need to up your CPU voltage, LLC or both. I just had the same issue myself but only while playing GW2. GTA V is the king for testing GPU stability but not so much CPU. When you're stable playing GTA V I would up the voltage again by another .005mv to be on the safe side.

Since increasing the voltage by .005mv using ultra LLC I haven't had a single crash or reported error.
 
grey/black/freezing screen has always been cache voltage for me, maybe a combo of both cache and vcore

Sorry, do you mean up the voltage on the graphics card or CPU?

It's happening even when I've set the CPU to stock. Do you have a link to a guide for overclocking on X99 as all I done previously was set XMP and then set multi to 44 and set voltage at 1.2V.
 
i was meaning the CPU voltage. How long have you had the system for? Were you able to play GTA V previously without crashing or have you just started playing?
 
Well I've just tried GTA again as I was playing BF4 this evening for about half an hour and it was fine.

10 minutes in the screen went black, fans on my GPU stopped and VGA led on my motherboard came on. Machine rebooted itself but had no display output.

Power cycled it and looked in event logs but no WHEA error this time so I'm thinking my GPU may be on it's way out.
 
Just an update on this....

I got a RX 480 in the black friday sales and have no longer had this issue therefore assuming it was my 7850 failing.
