Fixing memory bandwidth on Jinyue X99M-PLUS D4?
When running a high-precision emulator, any tiny micro-stutter is an absolute nightmare for platforming. Monitoring showed the Jinyue X99M-PLUS D4 was only hitting 35GB/s memory bandwidth, which is pathetic for a quad-channel setup, causing an instruction queue pile-up. I tried increasing the software cache allocation first, but RAM usage just spiked without fixing the stutters—another dead end. I eventually followed the manual to rearrange the RAM sticks into the correct slots and manually bumped the frequency from 2133MHz to 2400MHz. In AIDA64, the read bandwidth jumped from 38GB/s to a healthy 62-68GB/s, and the stuttering stopped completely. The system went through two long memory training cycles on the first boot, which was a bit nerve-wracking, but it eventually posted. CPU temps are 55-62℃ and VRMs are at 65-70℃. The emulator's internal profiler shows stable frame times and RAM stays at 58-63℃.
