Hello, this is going to be a long post so kindly bear with me but I'll also leave a TL;DR below: I currently have this old GT440 "Mac Edition" from Inno3D that runs absolutely fine on my old Optiplex machine with a Core 2 Duo but refuses to run (black screen, no beeps and the system boots just fine) on my "new" Sandy Bridge system with a Xeon E3-1270 (i7-2600). I used to have an RX470 that ran fine with the Xeon but I sold it, due to obvious reasons, and now am stuck with that GT440 for the foreseeable future. My theory is that the reason GPU runs on my C2D E8400 is because Macs used to have Wolfdale CPUs as well. I think the GPU wasn't designed with Sandy Bridge Macs in mind, hence it refuses to run. Now, I'd like to install a standard "non-Mac" BIOS on that GPU so it can finally run on my PC but the problem is that I can't seem to find any BIOS that matches the exact BIOS number of my GPU (70.08.29.00.01). I'm thinking about flashing either Zotac or Palit's BIOS which have the exact same BIOS number except the last part where it's .00 as opposed to .01 so their BIOS is supposedly slightly older and hence 'may' be compatible with my GPU. Do you think I should re-flash the card with Zotac's BIOS or is there something I'm missing? TL;DR Trying to re-flash the BIOS of my "Mac Edition" card with a standard GPU's BIOS because it's not working on my new PC and I think re-flashing a standard BIOS would fix the issue.
