Not bad, just happy to get over 15k. Haven't done any tweaking to my system since I swapped motherboards a month or two back. (Swapped out Asus Proart X870E to go with the Asus Rog Crosshair X670E Hero.) Just put the gpu core speed up a bit and memory for the test.
Would be interesting to try out that 800W bios just for fun, but it looks like cards need 3 fan headers to use it (?) from the quick check I did. My Zotac 5090 Amp Infinity Extreme only has two from the techpowerup teardown I looked at. Oh well.
One of the more interesting things about the 5090 is that in general there are almost no reference clocked cards available to buy besides the FE
I have a rare Zotac 5090 with reference clocks, same base clocks as the FE. This is what a reference 5090 looks like when run stock. I got it for MSRP a few months ago now
CPU is a 9800X3D but that doesn't matter for Speed Way which is 100% a GPU benchmark
