RAM stability issues

Eris · June 24, 2021

Hello! I'm having some really annoying issues with my RAM and I'm not sure what's causing them.

I have 2 sticks of 16GB 2400MHz Corsair Vengeance LP, installed in slots A2 and B2 of my MB as per manual, MB is an Asrock Z370 Pro4. CPU is an i7-8700k, stock clocks.

Issue is, I cannot set the memory at 2400MHz, it causes huge stability issues, but only when playing WoW or running a memory stress test, so at the moment I'm running at default 2133MHz. Windows will freeze or blue screen at seemingly random intervals/on random actions. I've tried the XMP profiles as well as manually setting voltage and frequency, no difference. I've gone through a Windows reinstall with no luck, updated the BIOS, nothing works. Unfortunately I don't have any BSOD logs since I just reinstalled Windows, BSOD error code was always DPC_WATCHDOG_VIOLATION. Following the reboot I always got a notification saying "Application blocked from accessing graphics hardware. Wow.exe has been blocked from accessing the graphics hardware", but after stress testing the GPU for 48 hours straight with zero issues and seeing as changing the RAM to 2133MHz fixed it, I think it's the RAM. Anything I could do to more permanently fix this?

Try booting linux mint off a bootable usb and see if it crashes at 2400mhz

You want to run linux mint on live mode aka itll run off your usb instead of installing it on your hdd.

If linux crashes then its a hardware fault, if it doesnt then its prob a windows issue

If you have a spare USB stick, formatted to FAT32, you might want to run Memtest86+ https://www.memtest.org/

Have to enable legacy boot in BIOS perhaps..

Done it, test passed with 0 errors using the XMP profile.

Opened WoW, within 10 mins it froze some 3 times but recovered and then finally crashed with

ERROR #132 (0x85100084) Fatal exception!

Program:	D:\World of Warcraft\_retail_\Wow.exe
ProcessID:	11624
ThreadID:	11248
Exception:	ACCESS_VIOLATION

The instruction at "0x00007ffbcc0f7899" referenced memory at "0x0000000000000000".
The memory could not be "read".

but Windows did not crash this time. Maybe some compatibility issue or maybe just Windows being bad? Or maybe it's just WoW. idk
