For our manual overclocking tests, we used MSI Afterburner. Our best results are as below.
As mentioned, the power limit is locked for the GTX 1630 and can’t be increased, but we still managed an extra 160MHz on the GPU. For the memory, we added an extra 690MHz, bringing speeds to 13.3GBps, but trying to push beyond that figure would result in the screen flickering and the graphics driver would reset.
That overclock saw the card’s average operating clock increase from 1845MHz stock, up to 2010MHz, resulting performance increases of 10-11% in the titles we retested, which isn’t bad at all. It’s hardly going to make the card suddenly hit 60FPS in every game, but there is definitely some extra headroom left untapped.
