How do they handle the signature requirement for the VBIOS? I could perform such a mod, but the requirement for a signed VBIOS puts me off. What if timings are wrong, such as with this attempt: https://www.computerbase.de/forum/threads/projekt-rtx3070-umbau-auf-16gb-mit-8gb-16gb-schalter.2271260/#post-31493388 https://www.computerbase.de/forum/threads/projekt-rtx3070-um... I guess that's not what they do, as they do not warn of a specific software configuration. Maybe this is why it is only compatible with 2080Ti GPUs?
