How to fix VRAM bandwidth issues on Vastarmor RX 9070 XT?
Using a Super Alloy Pro should be a breeze, but getting random drops during firefights makes me want to roast the driver compatibility. The VRAM bandwidth on the Vastarmor RX 9070 XT Super Alloy Pro showed abnormal fluctuations of 15-22% under extreme loads, sending frame times spiking to 40ms. I tried the High Performance power plan first, but all it did was make the fans scream while the lag stayed—a total waste of my afternoon. I eventually went into the advanced driver settings, locked the VRAM frequency at 2500MHz, and set power management to Maximum Performance. In AIDA64 GPU stress tests, the system ran for three hours without a hitch, and the FPS stabilized between 140-160. I actually tried flashing a third-party microcode before this, which made the card disappear from the system until I cleared the CMOS to bring it back to life. GPU temps stayed 65-72℃ and VRAM 85-91℃. The drops are gone, and I've backed up the config.
