Some Games Crashing with G.SKill 32gb 7600mhz XMP I on

[YJMalmsteen]

Cpu: i9-13900KS

Motherboard: Asus Rog Maximus Z790 Hero (BIOS 0904)

Ram: Trident Z5 DDR5-7600 CL36-46-46-121 1.40V 32GB (2x16GB) F5-7600J3646G16GX2-TZ5RK

When I turn XMP I on, some games will crash totally random (but sometimes crashing not happen) without giving any error.

I checked the qvl list, they should support each other. How should I set up in BIOS with the xmp?

the issue probably is that you have a 4 dimm motherboard. anything above 7200 requires tweaking/knowledge of overclocking ram on a 4 dimm motherboard.

if you wanted xmp click and forget at that speed you would need a 2 dimm motherboard. sorry to say. try lowering the speed to 7200 and see if the crashes happen.

Hi @YJMalmsteen 

The overclock is unstable, you can try XMP II to relax some of the memory subsets, see if this helps stability.

XMP/EXPO I - This is the validated board profile. Every time a board is validated with a particular memory kit, the memory vendor and ASUS use this profile to validate the kit for the QVL.

XMP/EXPO II - This is the default DIMM profile from the memory vendor and contains sub-timings stored within the SPD EEPROM of the memory module. 

XMP/EXPO Tweaked - This is the fastest profile and contains various tuned sub-timings and memory parameters. 

For better success in achieving "plug and play" overclocking, consider memory kits that are one to three frequency bins below the motherboard's maximum qualification on the QVL. The higher the frequency and tighter the timings, the more likely manual tuning might be needed to adjust for signal variance between parts—success with memory kits at or near the top of the QVL validation table depends largely on the quality of the CPU memory controller.

it passed memtest?

Memtest86+? You need to test in the OS. Memtest86 can detect module faults, but intermittent instability can be harder to catch. Would recommend TM5 or Karhu RAM Test.
