Hey everyone,

I’m having a really annoying stability problem with my RAM and I can’t figure out what’s causing it.

Specs:

• MSI Z790 Gaming Plus WiFi
• Intel i7-14700K
• RTX 3070
• Corsair Vengeance DDR5 32GB 6000MHz CL36 (XMP / EXPO kit)

The issue:

Whenever I turn on XMP in the BIOS to run the RAM at 6000MHz, my PC starts crashing sooner or later:

• Crashes when launching games
• Sometimes even when going back into Windows
• Basically unstable in general under any load

What I’ve tried:

• XMP at 6000 → crashes
• 5600 → still crashes
• 5200 → still crashes
• Only stable at default 4800MHz

I also tried manually changing RAM voltages (DRAM voltage / VDD / VDDQ), but it didn’t really help.

Question:

Any idea what could be causing this?

Is it:

• The CPU memory controller on the 14700K?
• A BIOS issue on this board?
• Bad RAM kit?
• Something wrong with my settings?

Would really appreciate any help or similar experiences 👍
