Question Can't get RAM & CPU to sync - XMP failing - games crashing

[alexsezian]

Hello!

I've built my new dream PC, but I can't get to stabilize:

CPU = Intel i7 12700k
MB = MSI MPG Z690 CARBON WIFI
RAM = Corsair VENGEANCE DDR5 64GB (2x32GB) DDR5 5200 (PC5-41600) C40 1.25V - CMK64GX5M2B5200C40
PSU = Thermaltake Toughpower GF3-1200W
Bios = updated to the latest ver.

Games are crashing within the first couple of mins;

What I have tried so far:
Without XMP (at 4800)
With XMP (at 5200)
Higher/lower XMP (4600 to 5400)
Increase the voltage from 1.250v to 1.3v
Increased the CPU’s clock rate from 100 to 108.35 to match the XMP at 5200

All failed 🙁
Any suggestions or ideas? I’m desperate here.

To making things clear: by crashing I mean the game crashes & it sends me to the desktop (not the system crashes).

All cables are connected, all drivers are up-to-date, I believe it's just a matter of balancing the RAM settings with the CPU.

Put a copy of memtest86 on a flash stick.
Boot the flash stick and let it run......no errors allowed.
