I have a Z77X-D3H (Rev 1.0) (Bios v. F18i, from the Gigabyte website). I have a i7 3770K and Arc 750, I’ve tried to follow guides on how to unlock hidden above 4g but no chance, and I’ve tried to flash my bios with an bios with ReBAR inserted (found a guide on github).
But still nothing, can some one please for the life of me help me, either make a modded bios for me or guide me how else I can do it. thanks in advance!!
-EDIT- Thanks Karfel for responding, I tried most of what you linked, none ‘worked’, but it wasn’t that, its just my BIO never shows it (so each time i tried, i had to go into GPUZ)
incase anyone else has the same as me, this is what I did to get above4 on, and rebar to 2gb (maximum, 4gb crashs)
add rebardxe to bios file, (skip everything else), Qflash new bios file.
follow the hidden above4g instruction, and on every reboot, instead of checking bio is if available, full boot into windows and run GPUZ and check.
once GPUZ shows everything is on for ReBAR (except ReBAR) and you have flashed the new bios. Run ReBarState.exe, enter Number 11. reboot,
(if 11 didnt work) Reset CMOS by unplugging wall socket, and remove CMOS battery for a while, then do the above hidden above4g again and rebarstate then try 10. confirm with GPUZ
use MMTool a4 > put the .ffs file under very bottom volume with same volume as PciBus > go to UEFIPatch section > check for pad file issue (if it doesnt change you’re good to go) > if your bios patch file apply some patch that required some DSDT modification > flash the bios
just in case peripherals broken when in bios add this in patches.txt
