System

Motherboard: B560M DS3H V2 rev 1.0
BIOS Version: F4 mod (No patches can be applied to input file)
GPU: RX 580 2048SP with rx 570 bios 4GB
[x] CSM is turned off. Make sure to confirm this in the BIOS and not with GPU-Z or similar since it can be inaccurate
[x] 4G decoding is enabled. Make sure to confirm this in the BIOS and not with GPU-Z or similar since it can be inaccurate
[ ] UEFIPatch is applied (see Using UEFIPatch for more information). On some motherboards DSDT Patching is also needed
[x] I have read Common issues (and fixes)

Description

I have managed to mod the bios with rebar and now the rebar is working at 4GB, but according to the wiki (https://github.com/xCuri0/ReBarUEFI/wiki/Common-issues-(and-fixes)#how-do-i-enable-resizable-bar-on-unsupported-amd-gpus-) i should downgrade my bar to 2GB because my gpu is unsupported, but when i change the bar size with ReBarState and i reset, the bar size is still 4GB.

@Toyo-tez Disable Resizable BAR in your BIOS menu, that's the only thing that can cause an issue like this. If you're going to use ReBarUEFI you should always have Resizable BAR in BIOS menu off but 4G decoding on.
