Yes, I'm using Flare X 2x8 ddr4 3200mhz cl14 rams designed for Ryzen. On bios section, XMP profile is selected also had to increase ram voltage about +0.140 V to work properly at about 1.35-1.36V
Mine works well except the slow post times. It takes like between 16-18 seconds to post. It's a common problems I guess especially with the MSI boards. Couldn't find but is there any solution for this?
