Hi,
I have recently installed two 8gb sticks of corsair vengeance LPX CMK16GX4M2B3200C16 on a AB350 Gaming K4 motherboard and can't get the speed of 3200mhz. I have changed the settings in the bios to xmp profile, the computer restarts a few times, then when I check the speed in CPU-Z its still at 1064.1mhz. My CPU is a 1500x    
Any help is much appreciated

thanks for the reply, I installed the latest bios and upgraded to the 3600, when I changed the ram setting to xmp profile 1 the computer wouldn't boot. I had to restart a few times until it would boot with the ram at 1064.5. Not sure where im going wrong

For the Ryzen 3600 you may have to wait for Agesa 1.0.0.3 or 1.0.0.3 ABB, they come with ram performance.
activate the xmp and instead of 3200mhz choose 3000mhz, to run at 3000mhz is a bios problem that does not let you use 3200mhz

I got the same mobo and recently updated it to 3.40 (Bridge BIOS) to get my 1700 run with 2x8GB GSKill Flare X 3200 16-18-18 at XMP.

It may have a chance you got an early MOBO revision with a somewhat outdated BIOS. Zen struggled a lot to support RAM frequencies from the beginning.

Updating your BIOS can be a simple solution and still the risks of doing it are low.
