How to fix memory controller lag on Jginyue B760M D5?
The memory scheduling on this board is like watching a snail race. In the open areas of Tales of Arise, my FPS was bouncing between 40 and 80, which is just pathetic. The Jginyue B760M Gaming D5 in Gear 2 mode was hitting 110-120ns of latency—a total waste of hardware. I tried lowering the graphics to Medium, but the game just looked blurry and the stutters remained. I eventually forced Gear 1 in the BIOS and bumped the DRAM voltage to 1.35V to keep it from crashing. Monitoring with RTSS, the frame time graph went from looking like an EKG to a flat line at 14-18ms. I did hit two Blue Screens of Death during launch, but loosening the tRFC to 500 finally stabilized it. RAM temps are 55-61℃ and CPU is 65-71℃. Exported logs confirm frame times are now rock steady at 14-18ms.
