How to fix memory timing instability on Jginyue B760M Gaming D4?
The texture flickering was a nightmare, especially when galloping on Torrent; distant buildings looked like they were glitching out into fragments. The default XMP profile on the Jginyue B760M Gaming D4 was struggling with the massive open-world assets, with memory latency bouncing between 88ns and 112ns, causing micro-sync errors. My first instinct was to drop texture quality to Medium, but that just made the game look like mud, which felt like a total cop-out. Instead, I dove into the BIOS memory settings and manually tightened the primary timings from 18-22-22-42 down to 16-18-18-36, while bumping the DRAM voltage from 1,2V to 1,35V. Using a latency analyzer, I saw the delay tighten up to 72-78ns, and the flickering vanished completely. It was a struggle, though—I blue-screened three times trying to push the timings too low until I loosened the tRAS to 40. Now the RAM stays cool at 46-52C and the chipset is around 58-63C. I ran four full cycles of MemTest86 and got zero errors, so it's finally rock solid.
