Code 12 in Windows with Tesla M40 on Asrock Z77 Extreme4 about rebaruefi HOT 4 CLOSED

I tried this with BIOS version 2.90 and nothing changes, still hanging on 0x95 with the card, still booting without it.

Went back to 3.00 and performed the workaround that I read as being only really useful on Linux, and the board POSTs fine. Got into Windows and am met with a Code 12. Also, both GPU-Z and HWiNFO display that ReBAR is still not supported. (I hear GPU-Z is pretty flaky with its readings, it also tells me that 4G decoding is on even though I disabled it)

yes, UEFIPatch is required for these boards to POST with any BAR larger than 4GB.

Windows doesn't allocate PCIe resources by itself but if you really need it working on Windows you could write an EFI application to assign the GPU BAR address and run it before Windows loads.
