| Passing GTX780 at BUS 5 (PCIEX4) | |
| OVMF: works even from the moment bios starts - weird perfomance - fps variates a lot, | |
| ACUnity and RE6 runs at half fps it should, system interface is | |
| almost as smooth as native. | |
| SeaBios: tested only Windows setup, which also works, I can see bios working too. | |
| Passing GTX780 at BUS 1 (PCIEX16) | |
| OVMF: error code 43 | |
| SeaBios: error code 43 | |
| Even with MSI forced, audio through HDMI is sometimes cracking, sometimes not, | |
| when audio cracks vps variations are higher... | |
| Useless observations: | |
| * I did tried to backup GPU ROM while on BUS5 using TechPowerUp's GPU-Z, and then try | |
| it (still in BUS5), the result is no video + Windows freezing while loading. So probably | |
| it's a bad ideia to use a ROM.... | |
| * Though I did enabled "ignore_msrs" as suggested in Arch's Wiki, GeForce Experience | |
| still complains about my GPU being incompatible. |
