Hey there! I have the B550m itx/ac paired with a Ryzen 3600 and a 2x8gb corsair 3600 16-19-19-36 (CMK16GX4M2D3600C16).

Cant get XMP to work even though im on the latest BIOS, i assume because my RAM is a very new skew and it is not supported by ASRock as of yet. What does one do in such a situation? Should I be manually adjusting my voltage/clocks/timings using DRAM calculator?

Alternatively, can I talk to asrock support? Would they be able to tell me anything other than buy new RAM/a different motherboard? Unfortunately Corsair LPXs are the only modules that fits under my CPU cooler (ID-60).

Thanks for any help.

Your best bet is DRAM calc, there are countless tutorials out there on how to set
things up. XMP has never been very good on Ryzen, think of it as a preprogrammed
overclock (which it is) that may not be stable on every system without tweaks.

A fast and dirty trick is to enable XMP and then manually lower the frequency to
around 2666, save and exit and see if the system boots/is stable, if so bump up
to the next frequency up the list until you lose stability. This will usually get
you in the region of 3200 maybe higher.
