Fixing memory frequency instability on Galax B760M D4?
The game would just freeze for about 0.5 seconds the moment a fight started, which is absolutely lethal in a fast-paced action game. The auto-overclocking on the Galax B760M D4 was jumping wildly between 3200-3600MHz during heavy rendering, pushing memory controller latency up to a brutal 110-130ns. My first instinct was to increase the virtual memory to 48GB, but that was a waste of time—loading screens actually got 3 seconds longer. I went back to BIOS, killed the auto-OC, and manually locked the RAM at 3200MHz with the divider synced at 1600MHz. Running AIDA64 memory stress tests, the read speed stabilized at 42-45GB/s and latency dropped to 72-78ns. I hit a wall at first where the system wouldn't even POST, but bumping the RAM voltage from 1.2V to 1.32V fixed the boot loop. Core temps sat between 55-61℃. After 4 full passes of MemTest86 with zero errors, the RAM temp stayed chilled at 58-63℃.
