BSOD ATTEMPTED_EXECUTE_OF_NOEXECUTE_MEMORY (fc)

[lleonidas004]

Hi,

I recently overclock my pc....offset overclock at 4.4 ghz @ 1.24v...after that...

1. I run 24 hours Prime95 and stable no bsod
2. PC has no problem doing web browsing and other things
3. Run Skyrim Ultra High setting using Mod Organizer...within 15 minutes the system crashes and sometimes hanged
4. Stress test GPU using Furmark...no issues....

Here is attached zip file...Please help...

0xFC are virtually always down to drivers, your nVidia driver is being blamed for your BSODs.

Download the latest driver for your card from here and follow NVIDIA Drivers - Avoid Problems for the cleanest possible install.

I try to completely uninstall the nvidia driver but i didnt work...the graphic driver keep reinstalling itself after reboot...even after i disable windows update, disconnect from internet...it still reinstall graphic driver after reboot...

Then I found this link How to Completely Uninstall all AMD/Nvidia GPU Drivers - Nvidia - Graphics Cards

It really work!!

But BSOD still happen...but different error code each time..

1. CLOCK_WATCHDOG_TIMEOUT (101)
then shortly after

2.WHEA_UNCORRECTABLE_ERROR

When I saw second error I found this page..

BSOD/random restarts due to WHEA_UNCORRECTABLE_ERROR - Crash - CPUs

Someone name Nieru Senju suggested that it probably caused by under/overvoltage when overclock

Even though I have done 24hours of Prime95....I really feel this got to be the voltage problem...like he suggest.

so I add 0.005v to the offset value....since now it does not BSOD yet..

I will report again if anything happen but today

I learned that Prime95 seems unreliable...but today I learned how to completely uninstall Nvidia driver

and the clean install fix some lag during my system boot to windows...

I think nvidia driver driver is not the cause of BSOD....one thing that keep occuring in the BlueScreenView is ntoskrnl.sys

Futher reading and scouring the internet suggested that it was related to bad overclocking...that I overclock memory too hard.

When overclock I just set the memory to xmp profile and play with multiplier...so I try to downclock the memory.

1. turn down memory clock from 1600 to 1400
2. set the memory timing manually.

try to play games....turn out ok....I will do the stress test again if its ok I will try to go from 1400 to 1600 while keeping the memory timing in manual mode..

Yeah if you've received a 0x124 then you need to remove any overclocking you've done just to get stability back.
