The issue is that when I am in BIOS (x370 Gaming Plus with the updated BIOS ver.) I see that my DRAM Frequency is at 2133 Mhz. I have 16GB (2x8GB) GSKill F4-3200 sticks. I do see a radio button for A-XMP Profiles 1&2. 1 is 2933 Mhz and 2 is 3200 Mhz. I activated the A-XMP profile 2, booted and I got a black screen and error that no OS drive could be found and press any key to continue. Pressing a key didn't do anything but give me the error again. I ended up having to clear the BIOS by jumpering the battery and then it booted normally. I am nervous to try it again. I really would like to utilize the speed of my RAM and was wondering if anyone had any good advice for me? I'm leaving a lot of speed on the table I fear with the configuration that is being used right now.
