With certain tweaks to the GPU, including vCore running at 1069mV, as well as plenty of liquid nitrogen, Vince Lucido managed to hit 2.58GHz GPU clock with memory running at 21.5Gbps.
Such settings and a bunch of LN2 were enough for the RTX 3090 to hit 16.673 in 3DMark Port Royal, which is the new world record.
In case you are wondering, this is an over 50 percent increase in GPU clock and just over 10 percent increase in memory clock. The end result in 3DMark Port Royal is around 30 percent higher compared to a stock RTX 3090 card.
