How to sync clock speeds for VastArmor Radeon RX 9070 XT?
The game had this awful 'sticky' feeling whenever I zipped through the city, which is a total dealbreaker for a high-speed action game. Digging into the logs, I found the RX 9070 XT's auto-boost was constantly shifting frequencies, causing memory latency to bounce between 82ns and 110ns. I tried increasing the page file to 64GB, but that was a complete waste of time; my minimums were still hovering around 42 FPS. I finally went into the Adrenalin panel, killed the auto-overclock, and hard-locked the core clock at 2.4 GHz while tightening memory timings to 18-18-18-36. The RTSS frame time graph went from a jagged mess to a flat line, and my minimums jumped from 42 to 65 FPS. I did run into a couple of driver timeouts early on, but bumping the core voltage from 1.1V to 1.15V stopped the crashing. The GPU now stays between 68-74℃ and VRAM hits 82-88℃. I ran four consecutive 3DMark stress tests with zero errors, and the memory temperature stayed locked in that 82-88℃ window.
