need help with XMP

[Drifloon]

I recently built a pc that originally had the issue of not booting up when I enabled XMP (haivng a red DRAM light on motherboard), I then fixed this by updating the BIOS and all was fine for around 2 weeks till today when my pc wouldn't boot and the motherboard had a red DRAM light on. So I assume the issue is XMP and need help as to make XMP more stable.

Specs

CPU: ryzen 9 7900x
RAM: vengeance DDR5 7200MHz

Mother Board: b650 aorus elite ax

GPU: Radeon RX 7800 XT

The CPU can't handle that speed. You will have to disable DOCP and manually set the ram speed to around 6000 MHz. If it works and is stable, you can creep at higher and higher speeds.

7200Mt/s is not a speed you actually want to use. Because of how the memory controller works, speeds above 6000MT/s are slower than speeds at or below 6000MT/s, so 7200 is slower in nearly every aspect than 6000 CL30. 

 

Manually enter in the XMP parameters for 6000 CL30, that should just work, fix your issues, and you'll get a bit of a performance uplift at the same time as well
