I have a Fatal1ty AB350 Gaming-ITX/ac motherboard running the latest BIOS (P4.70) paired with a Ryzen 2400G processor. I am using a 16GB (2 x 8GB) kit of Patriot Viper 4 DDR4-3000 memory (PV416G300C6K) which is on the Memory QVL for Raven Ridge. I have tried enabling the XMP profile, but I can't get the RAM to run above 2133MHz. I have tried clearing the CMOS, but the same result. When I first powered on the PC during the build, I enabled the XMP profile and restarted and the BIOS showed the RAM as DDR4-2933, but since then it has gone back to DDR4-2133. I have not been able to get it to show DDR4-2933 again. Any suggestions are much appreciated. Thanks in advance!
