Dealing with memory crashes in RDR2 on Biostar B550MH
Every time I panned the camera across the plains, the game would just crash to desktop without any warning—it was incredibly stressful. The memory controller on the Biostar B550MH struggled with the massive texture streaming from the 4K MOD, resulting in signal jitter of 1.8-2.4ns. I wasted hours trying to increase the page file to 64GB, which reduced the crashes slightly but added a miserable 10 seconds to every loading screen. I eventually went into the BIOS and bumped the DRAM voltage from 1.35V to 1.38V and loosened the tRCD timings by 2 ticks to improve compatibility. In my side-by-side tests, the crashes (which happened twice an hour) completely stopped, and frame times tightened from a messy 18-42ms to a consistent 14-22ms. I almost fried something when I initially pushed the voltage too high and saw RAM temps hit 62℃, but dialing it back to 1.38V stabilized everything. RAM now sits at 48-54℃. AIDA64 shows zero errors, and the mouse input finally feels snappy again.
