Question Why won't my RAM run XMP stable?

[Britcanting]

Hi

I have a Z690 Gigabyte gaming x DDR4 Motherboard with 12900K with the latest BIOS version which is F8.

The RAM is Corsair vengence 4x8gb 3200mhz. It's fine at the stock setting of 2333mhz I think but when I set it too XMP in the BIOS Elden Ring will freeze after about 30 min but never when its at 2333mhz.

Is this faulty RAM or something else?

Thanks!

Was it a 4x8gb kit or 2 kits of 2x8gb?

Two 2x8gb kits.
