How to fix VRAM crashes on Soyo SY-A320D4+ for MHW now?
I can't even describe how annoying this was—every time a big monster used a special attack, the game would just vanish. The Soyo SY-A320D4+ had some unstable voltage swings around 2666MHz in its factory OC state, leading to VRAM address checksum errors. I wasted half an hour reinstalling drivers, which did absolutely nothing and just made me more angry. I eventually used a tuning tool to downclock the VRAM by 100MHz and tweaked the core voltage to 1.02V. In 3DMark, the crashes went from 4 per hour to zero. I noticed a tiny 2 FPS drop after the downclock, but I got it back by enabling Hardware-Accelerated GPU Scheduling in Windows. VRAM temps are now 60°C - 66°C and the core is 52°C - 58°C. I saved the stable profile using a config snapshot tool, and the core voltage is now rock steady at 1.01V - 1.03V.
