Here is my 4090 FE with galax 666w bios running speedway, it can do about 2.8% more than the stock bios, not sure why I can only see 417w power draw in GPUZ though, also tried flashed the XOC 1000W bios, but then realised I only have a 650w Corsair SFX and that wasnt a good idea, quickly flashed to the galax

, also you need to disable core isolation in windows settings for the flash tool to work :
