Overclocking

GPU-Z Screenshot for Overclocked Graphics Card

GPU-Z is currently unable to show the GPU overclock. Monitoring it with the sensors on 2nd tab works though.

Overclocking works roughly the same as on the Radeon RX 7900 Series. What's most important is that you MUST lower the GPU voltage, or you won't see meaningful performance gains.

My test method is the following:

Bump the maximum allowed GPU frequency by like 400 MHz to make sure it doesn't end up limiting you in any way. If you set it too high, the card will become unstable.
Now find the maximum stable memory clock. Increase memory frequency gradually and run benchmarks. At some point, the FPS will stop climbing and go down. This is your maximum frequency. You can set higher clocks and there won't be artifacts, but performance will be reduced due to the error correction kicking in.
Once you've figured out memory, gradually lower the GPU voltage until the card is no longer stable, then back up a little bit for extra stability.
Done
