How to calibrate power delivery on Galax B760M Black Knight?
The glitchy flickering on the walls eventually led me back to unstable power delivery from the motherboard. The Galax B760M D4 Wi-Fi Black Knight had memory voltage swinging between 1.2V - 1.35V, which was triggering constant memory controller checksum errors. I tried updating the drivers first, but that actually made the flickering worse—a total nightmare. I decided to go into the BIOS and manually bump the memory voltage to a stable 1.38V. Using a stress test, I saw the RAM temps sitting comfortably between 42℃ - 48℃. Just adding voltage wasn't enough, though; I had to disable all power-saving modes and lock the CPU frequency before the textures finally stopped acting up. The CPU package power settled around 85W - 92W, and the heatsinks felt warm to the touch. After a long session of benchmarking, I saw memory latency drop from 68-75ns to a snappier 62-66ns. No more random reboots, and the RAM temp stayed locked at 42℃ - 48℃, although the BIOS interface is still a bit clunky.
