To be honest im not a fan of user benchmark. Use Ryzen Master or HWinfo64 if you want to show info on your hardware
But in any case 32 gigs DDR4 at 3200 cas 14 or most ideally 32 GB DDR4 3600 cas 16 should be fine. You may want to ensure you have XMP or in AMD’s case DOCP enabled in the Bios for best performance.
Also while your in the bios please ensure that PBO (Precision Boost Overdrive) is turned on and you probably can enable the +200mhz OC boost as well.
