Fixing memory checksum errors on Galax B760M D4 Wi-Fi
Right in the middle of exploring these creepy mazes, the game would just crash to desktop without warning, making the stealth experience feel totally fragmented. The D4 slots on this Galax B760M were seeing 0.05V transient drops between 1.2V and 1.35V at 3200MHz, which caused the memory controller to trip during heavy asset loads. I tried downclocking to 2666MHz first; it stopped the crashes, but my 1% lows tanked from 45 to 32 FPS, which was too big a performance hit. I ended up going into the BIOS and manually bumping the memory voltage to 1.38V and loosening the tRCD and tRP timings by 2 counts each. After 4 full passes of MemTest86, the errors that used to pop up twice an hour completely vanished. I did notice memory temps hit 62℃ after the voltage bump, so I had to slap on some small heatsinks to get them back down to 50-55℃. VRMs are at 60-66℃. Stress tests confirm the read/write is synced, and temps are stable at 50-55℃.
