Missing adjustable bar item.
Missing adjustable bar item.
I have a Gigabyte B550 Gaming x v2 Rev1.3 board, but the Re-sizeable bar setting isn't visible at all. No one seems to know why. This is listed in the I/O settings menu, and I've checked everywhere else without success. I'm trying to get the Intel Arc B580 working, but the BIOS is disabled and the firmware is the latest version. I thought the Re-Bar option should appear, but I haven't found it anywhere. I discovered this on GitHub out of desperation: https://github.com/xCuri0/ReBarUEFI/wiki...FFS-module
Yes, rebar is typically placed in the PCIE slot and works alongside the above-4G decoding.
