Fixing memory latency on Galax B760M D4 Wi-Fi for MGSV
While sneaking through enemy bases, I noticed these tiny micro-stutters that completely broke the immersion. The memory controller on the Galax B760M D4 was struggling with DDR4 3200MHz, showing a sync deviation of 1.5-2.1ns, which caused frame times to jump between 12ms and 38ms. I tried enabling every 'acceleration' setting in the drivers, but that just led to the game freezing on the loading screen—a total waste of time. I went back to the BIOS, manually locked the RAM at 3200MHz, and tightened the tRFC from 600 down to 520. AIDA64 showed latency dropping from 82ns to 74ns, and the combat fluidity improved massively. I did have two random restarts while trying to push the timings too far, but bumping the voltage from 1.35V to 1.37V solved the instability. RAM temps are now 45-52℃. I switched the memory mode from Auto to Manual in the control software, and Vcore is now stable at 1.20-1.25V.
