Fixing memory instability on Galax B760M D4 Wi-Fi for Metro
That buttery-smooth wasteland traversal is finally back. After recalibrating the memory sub-timings and flashing the latest BIOS, the micro-stutters during heavy asset loads dropped from 4 per second to zero. The perceived latency is night and day. I spent way too much time trying to force an XMP extreme profile at 3600MHz, but the memory controller just couldn't handle the complex instructions, leading to screen flickers every few seconds. I realized stability beats raw clock speed every time. I went back into the BIOS and stepped the primary timings down from 18-22-22-42 to 16-18-18-36, while bumping the VDD to 1.35V. AIDA64 latency tests showed a drop from 85ns to a tight 72ns - 76ns. I did have one disaster where the system rebooted 10 minutes into the game due to low voltage, but loosening tRAS to 44 fixed it. VRM temps stayed cool at 52°C - 58°C. Four passes of MemTest86 confirmed zero errors, and the RAM stayed chilled at 52°C - 58°C.
