I have following config: MSI B650-VC, Ryzen 7800X3D, T-Force DDR5 7200mhz, Radeon 7200 Mhz.

I had no issues: no BSODs, reboots or anything but I had weird issues with my OS: I get random screen flicker that appears for short period of time but only while being in desktop. Looks like something quickly trying to refresh on background. It was bothering me a lot so I reinstalled Windows. After reinstall I found that my network settings are somehow corrupted: the app called Netch that uses V2Ray VPN protocol just didn't work. Reinstalling Windows helped but then when I updated it to W11 it stopped working again even tho it was working on my friends PC all this time. I found this weird and I decided to test it via MemTest5 to see if RAM is ok and apparently it was not... I have fully default BIOS of latest version only with A-XMP enabled.

Do you think my RAM is faulty? I had no crashing, BSOD or issues in games or normal usage. At least yet. Been having this build for a week.

Anything I can try or RAM is faulty and need returning?

EDIT: Changing to A-XMP (2) to 6000@CL38 results in TestMem5 Extreme Anta777 preset to complete in one hour with no errors...
