Solving memory voltage crashes for Tomb Raider on Biostar B650MT?
Exploring those eerie ruins is great until the game randomly crashes to the desktop, which makes the whole experience feel fragmented. On this Biostar B650MT, the memory slots were seeing a 0.05V transient drop when running at 6000MHz, causing the memory controller to trip during heavy asset loads. I first tried downclocking the RAM to 5200MHz; it stopped the crashes, but my 1% lows dropped from 65 FPS to 48 FPS, which felt like too much of a performance hit. I went back into the BIOS, bumped the memory voltage to 1.38V, and loosened the tRCD and tRP timings by 2 counts. After 4 consecutive passes in MemTest86, the errors—which used to happen twice an hour—completely disappeared. I did notice memory temps spiked to 62℃ after the voltage bump, so I had to add some small heatsinks to bring it down to 50-55℃. VRM temps are 60-66℃, and the system is finally stable.
