Question Wrong Memory Speeds in Bios & CPU-Z

[erik.dunn]

Hello,

My bios is reading my ram as 2133 Mhz and CPU-Z is reading it as 1066.4 Mhz, though I've just checked and both 32 GB kits are 3200 Mhz. Right now I've got everything on auto, and I tried changing my "Memory Speed" in "Ai Tweaker" in my bios to DDR4-3200 Mhz and that put my computer into a boot loop. I'm assuming I did something wrong there... But any help would be appreciated. It's 2 kits of 16 x 2 DDR4 3200 Mhz Trident Z memory for a total of 64 GB. The motherboard is an ASUS TUF GAMING B550M. With an EVGA 850 GA PSU. Running an R9 3900X and RTX 3060.

Again, any help would be appreciated. I've done some snooping around to figure out the problem but haven't come up with anything.
Thanks.

Figured it out, got mixed up with the terms. I guess instead of XMP my bios reads it as DOCP. Either way, seems to have fixed the issue.

Of note, CPU-z reports the actual operating clock speed of the RAM. Your BIOS is reporting the DDR4 rating.

I gathered that, it's back up to 1600 Mhz in CPU-Z now. So, looks good to me.
