How to fix memory instability on Colorful B450M-T in Silksong?
During fast combat transitions, the frame rate was bouncing between 40 - 60 FPS, which is a huge red flag for an old board. The memory controller on the Colorful BATTLE-AX B450M-T was struggling with the new game's instruction sets, and the default XMP profile had a 3 - 5% error rate. I tried downclocking the RAM to 2666MHz, which stopped the fluctuations, but my 1% lows dropped from 32 to 25 FPS—too much of a performance hit. I decided to manually tighten the timings, moving the CL from 16 to 18 and bumping the voltage from 1.2V to 1.35V. In the frame time monitor, the 1% lows jumped from 20 to 35 FPS, making the game feel way smoother. I had two random reboots after the first voltage bump, but loosening the tRAS by 4 units stabilized everything. RAM temps are at 40 - 46℃ and the board core is at 52 - 58℃. Ran four passes of MemTest86 and got zero errors, finally giving me some peace of mind.
