Yeah these cards beg for undervolts. What continues to amaze me is how incredibly silent my card (MSI 3090 Suprim) is. Incredible piece of engineering. I've read online that it supposedly has some sort of switch between Silent and Gaming BIOS, but given my experience with ridiculous voltages and wattages i don't care about what Gaming brings to the table.I played around a bit with the voltage settings. It normally runs around 1700mhz at 70-73C due to the hitting the power limit, which tops out at 102% on this model without changing the BIOS, but setting it to 1900mhz at 0.881V seems to work nicely. I can get either 1900mhz at the same power and temperature, or setting the power limit to 90% gets 1800mhz with a 6-7C temperature drop and takes 50W off at the wall outlet. I think it can be pushed further but will leave it there long term.
And LEDs are cancer, i have mine in Meshify S2 case, had to move my top fans to block the light, of all places it has some minor logo on backplate, kinda wish that instead of wasting a good switch on BIOS switching, they had turn off ALL LEDs switch instead.
