Ryzen 5 3600 - 3000Mhz Ram

Hi,

I set up my first AMD-based rig. I'm using a Ryzen 5 3600 and 16GB of ram (Corsair CMK16GX4M2B3000C15), I'm running everything on the motherboard Asrock Steel Legend B450M.

My question is:

Should I run the memory sticks at 3000Mhz, 2666Mhz, 2667Mhz, 2933Mhz?

What is better for Ryzen 5 3600? I read, after assembling the PC, that not all Mhz in memory sticks work well with the CPU.

Cheers!

Boards made with only 4 layers are not able to run memory as well as the more expensive 6 layer ones.

The R5 3600 et al are all designed to handle DDR4-3200 max but your memory may come up at DDR4-2933 which is one JEDEC speed grade lower

Short answer: you should run the memory as fast as is stable, Ryzen CPU loves the higher memory mhz.   So i would really shoot for 3000 mhz on the ram, at the very least.  If that's not stable you could try relaxing some ram timings and fiddling around with that.   

Thank you. I'm going to leave in 2933Mhz, it's working fine for now, I think...

that speed should be the most stable

Thank you!
