How to stop memory latency spikes on Jginyue B760M Gaming D4?
There is nothing worse than sneaking up on a target and suddenly feeling like the game just yanked you backward; it completely ruins the immersion of feudal Japan. The default timings on the Jginyue B760M Gaming D4 (18-22-22-42) are way too conservative, leaving the memory controller struggling with huge texture indices and pushing latency up to 85-110ns. I tried increasing the page file to 32GB first, but that was a waste of time—it stopped the crashes but the micro-stutters actually got worse. I eventually dove into the BIOS and manually tightened the primary timings to 16-18-18-38 and bumped the DRAM voltage from 1.2V to 1.35V. In AIDA64, the latency dropped from 92ns to a rock steady 68-72ns. I did hit a wall early on where the PC blue-screened four times in a row, but loosening tRAS from 38 to 40 finally stabilized it. VRM temps are now 55-61℃ and RAM is at 42-48℃. After five full passes of MemTest86 with zero errors, the hitching is finally gone.
