Fixing memory training lag on Biostar B650MT for Crimson Desert
The memory compatibility on this board is a joke. With EXPO on, every reboot takes three minutes for memory training, and once I'm in-game, my FPS tanks from 90 to 40. It feels like the BIOS optimization was just an afterthought. I tried an XMP compatibility mode, but the system wouldn't even post—total disaster. I finally went manual: bumped memory voltage from 1.25V to 1.38V, locked SoC voltage at 1.2V, and slightly dropped the frequency to 5600MHz. In RTSS, my 1% lows jumped from 38 FPS to 62 FPS, with a tiny 5-10 FPS variance. The catch was that memory temps hit 65℃, so I had to rig up a small fan over the DIMMs to cool them down. CPU temps are fine at 75-82℃. I exported my profile so I don't have to do this again after a BIOS update, and the input response finally feels snappy.
