Hey all, I use a prebuilt Medion PC that I've upgraded over the years. So far I've put in new ram, a new PSU and a new video card, but I'm still using the original motherboard and CPU which I'm planning to replace near the end of the year. The locked down prebuilt BIOS doesn't let me enable XMP/DOCP, but it does let me manually set the ram values. The 2x8GB Corsair CMK16GX4M2B3200C RAM sticks I put in a few years ago are currently running at 2133MHz (Task Manager says 1067, CPU-Z says 1064.1). I've checked the motherboard's specs here and my Ryzen 5's specs here and both support up to 2666MHz.

In CPU-Z it shows me JEDEC timing tables and XMP-3200, but not the XMP-2666.

I've tried changing the DRAM Frequency in the BIOS before, but that made my pc not boot and motherboard beep, which was fixed by resetting the BIOS by taking out the battery (and maybe reseating the RAM too? I'm not sure. It didn't boot after resetting the BIOS and the beep code was about the ram, and reseating fixed that, but I'm not sure if the beeping is related to the BIOS or just that my RAM had to also be reseated by coincidence)

I've never overclocked my ram before or messed with any of the other values, so I'd love some help on what values to enter and for what fields for running the ram at 2666MHz. I'm not actually that interested in maximizing all the performance out of the ram, I'd just like the stable values that XMP would set it to. I should be able to figure it out if someone could figure out the values in this format:
CL – tRCD – tRP – tRAS – tRC – CR

Specs:

Motherboard: P2A4-EM B350
GPU: Radeon RX 7600
CPU: Ryzen 5 1600 (14nm)
RAM: 2x8GB Corsair CMK16GX4M2B3200C (I dont know the version number or die type)

Let me know if i can provide any more useful info!!

    Does the bios let you set the voltage for the ram?
