Gigabyte 4090 OC Not Detected

Hey yall, hoping to get some help. I just built a new pc with a 1000w psu, 7800x3d, 32gb ddr5, and the gigabye aorus b650 elite ax mobo. I had a 4060 laying around so I threw that in for a week or 2, then upgraded to a 4090. The 4060 worked fine with no issues, but the 4090 is throwing me for loops.

The 4090 has RGB and fans turn on but it isn't being detected in BIOS or in device manager. I have tried DDU, changing the connection speed of the PCIE slot, and reseating the gpu all to no avail. This is really bugging me as I've spent about 7 hours trying to fix this.
