How to fix XMP instability on ASUS TUF Gaming B760M-PLUS D4?
It's ridiculous that a board as 'stable' as the Artillery series would blue-screen me during a scene load. Checking the logs, I found that with XMP 3200MHz enabled, the memory controller was throwing parity errors under load, with voltage dipping between 1.34V - 1.36V. I first tried downclocking the RAM to 2666MHz, which stopped the crashes but tanked my 1% lows to 40 FPS—it felt like I was playing on a decade-old PC. I went back into the BIOS and manually locked the DRAM voltage at 1.38V and loosened the tRAS timing from 38 to 42. In AIDA64 stress tests, the memory stayed stable at 45℃ - 52℃ without a single reboot. I actually overdid it once and pushed the voltage to 1.45V, which caused the system to refuse to boot until I cleared the CMOS. Now, the CPU core voltage is steady at 1.22V - 1.28V, and my fan speeds are holding at 1400 - 1600 RPM. It took a lot of trial and error, but the system is finally rock solid.
