For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
While the stock power limit is set to 450W, this can actually be increased all the way up to 600W for the Gaming OC – the first partner card we've tested that can do so. I was able to add 170MHz to the GPU and 1575MHz to the GDDR6X.
This brought operating clock speeds up to 2910MHz.
The extra frequency brought gains of 6% in Cyberpunk, but then 8% in Spider-Man Remastered and Resident Evil Village, so the Gaming OC was just out-performing the Founders Edition when overclocked, but only by a fraction.
