Fixing XMP crashes on MSI PRO B760M-A WIFI DDR4 II
It was a complete disaster. My system would just blue screen without warning during heavy stealth sequences, which is beyond frustrating. The logs showed that with XMP 3200MHz enabled, the memory controller was throwing checksum errors under load, with voltage dipping between 1.34-1.36V. I tried downclocking the RAM to 2666MHz, but my 1% lows dropped to 45 FPS, which felt like I was playing on a decade-old PC. I went back into the BIOS, locked the DRAM voltage at 1.38V, and loosened the tRAS timing from 38 to 42. In AIDA64, the memory temps stayed between 45-52℃ and the crashes stopped. I actually overshot the voltage to 1.45V once and the PC refused to boot, forcing me to clear the CMOS to get back in. CPU core voltage is now stable at 1.22-1.28V. I backed up the BIOS profile so I don't have to do this again. Memory temps are still holding at 45-52℃.
