How to lock core clocks on Sapphire PURE Polar RX 9070 XT?
When the team fight effects fill the screen, the fluidity is amazing, but then these random frame drops hit and ruin the whole experience. The Sapphire PURE Polar RX 9070 XT core clock was bouncing wildly between low and high power states, causing the frame generation time to swing violently between 4ms and 18ms. I first tried enabling Low Latency mode in the drivers, but while the input felt faster, the stuttering rhythm remained—it was a frustratingly superficial fix. I eventually went into the advanced driver settings, manually locked the core clock at 2400MHz, and set the power management to Maximum Performance. In the RivaTuner graph, the frame time finally flattened out between 4-6ms, and the drops vanished completely. I actually pushed the clock too high at first and got some weird artifacts on screen until I backed it down by 100MHz. GPU temps stayed at 55-62℃ and VRAM was 68-74℃. Locking the frequency is miles better than the auto mode.
