How to fix VRAM instability on VastArmor RX 9070 XT in Naraka?
Right in the middle of a fast parry or counter-attack, the screen would just freeze for 0.2 seconds. It's a tiny glitch, but it completely ruins the rhythm of the fight. I used some monitoring tools and found that the VastArmor RX 9070 XT Super Alloy PRO had significant voltage ripples around 1.35V in high-frequency mode, leading to occasional data checksum errors. I tried downclocking the VRAM to 2000MHz, which stopped the stutters, but I lost about 15 FPS—I wasn't willing to take that hit. Instead, I went into the advanced driver settings and bumped the VRAM voltage to 1.38V while increasing the power limit by 10%. After four rounds of stress testing, the 6 checksum errors I was seeing completely vanished. The first time I bumped the voltage, the VRAM hit 98℃, so I had to overhaul my case airflow to bring it down to 88-92℃. Core temps are stable at 68-74℃, and bandwidth tests show no performance loss.
