GTX 780 booting to a blank screen

So i was using big sur (smbios iMacPro 1,1) with a gtx 760 with no issues. I upgraded to a 780 and now the system boots to a blank screen with a cursor. I thought gtx 780 was supported OOB. I can boot to recovery just fine. What can i do to fix this?I've tried boot args agdpmod=vit9696 and shikigva=40 with no avail
