How to fix memory bandwidth bottlenecks on Jingyue B760M?
The screen tearing was most obvious during quick-turn flick shots, and that visual disconnect totally killed the competitive vibe. The memory controller on the Jingyue B760M GAMING D4 was idling at 2666 MHz by default, pushing memory latency up to 95-110ns, which just couldn't keep up with the particle-heavy chaos of Destiny 2. I tried the easy route with XMP, but the system blue-screened after three minutes with a memory management error—totally unreliable. I had to go manual: locked the frequency at 3200 MHz, tightened the timings to 16-18-18-36, and bumped the DRAM voltage from 1.2V to 1.35V. In AIDA64, my read speeds jumped from 38 GB/s to 46-51 GB/s, and the tearing vanished. I did try to push it further to 14-16-16-34, but I started getting random checksum errors on boot, so I backed off. Now RAM temps are 42-48℃ and the VRM is around 58-65℃. After a four-hour stress test with zero crashes, it's finally rock solid.
