For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
With the Suprim Liquid X, the power limit can be increased up to a maximum of 530W. We added 180MHz to the GPU and 1650MHz to the memory.
In the titles we re-rested, this overclock netted an extra 6-7% performance versus stock. It’s fine overall and exactly what we have come to expect from the RTX 4090.
