The Story: So. I'm on a Gigabyte AX370 Gaming K7 motherboard. Originally I was waiting on a BIOS update in order to actually OC my RAM, because RAM OC wasn't happening at all on the release F2 BIOS. On the 7th of March, Gigabyte released BIOS F3. I flashed to it, and was stoked to see that XMP worked immediately, 2933 on my Trident Z RGB DIMMs. However, I tried overclocking my CPU with Ryzen master control. This sent my computer into an F9 error code bootloop. (F9 errorcode = No recovery module was found) To break out of the loop, I had to smash my restart button several times until it finally broke past the F9 code. However, I couldn't boot into Windows after this. TO fix this NEW issue. I flashed back into the old F2 BIOS, and flashed back to F3. I am now in windows after a system restore that corrupted my profile and i had to do some nasty regedit stuff just to get back into my profile and out of a temp login. WARNING: AFTER FLASH TO F3 DO NOT USE RYZEN MASTER CONTROL AT ALL. Doing so will botch your BIOS in such a way that XMP will no longer work. At all. even after a reflash. (Still unsure if I've wrecked my board just trying to get back into windows) Additional Findings: Once you have flashed to F3, You can not flash back to F2, and boot into windows. You will freeze on the windows execution screen 100% of the time, no matter what settings you tweak in BIOS or if you load back to Optimized Defaults. In my case, 6GB of my total RAM has also gone missing (I'm supposed to have access to 16GB, I have access to 10GB however). I am still unsure if this is a side effect of the BIOS, or if I've wrecked my board. In the mean time. I'll be waiting on a new BIOS update that hopefully resolves these issues. If it doesn't. I guess I'm RMA'ing this board. I'm pretty sure I'll still be covered under the warranty due to this being a BIOS issue, rather than a hardware issue.
