Predator PO7-650 XMP does not work after upgrading memory

pjotterplotter · April 22

Hi,

I upgraded my memory from the default stock memory
2x16GB (ADATA UDIMM DDR5 1Rx8 PC5-4800B-UA0-1010-XT)
to:
2x32GB (G.Skill Trident Z5 (Intel XMP) 64 GB (2 x 32 GB) SDRAM DDR5 6400 CL32-39-39-102 1.40V F5-6400J3239G32GX2-TZ5RK)

I placed these sticks in the same slots as the original where, and left the originals out.

But now when i enable XMP, it reboot a few times and then comes up with a message that there was a problem and the XMP will be reset to normal, without XMP the system boots and runs normally.

The bios is in default settings, I upgraded the bios to R01-A3 and also installed firmware V003, but without any help.

If i run cpuid it shows me this:

The memory frequency strikes me a bit odd since it doesnt match the specs of the dimms? Did i make a mistake buying these or is there any other setting i can try?

Thanks in advance!
