I’m trying to locate a BIOS for resizable bar for the Asus Z97 Pro Gamer, the latest BIOS version is Z97-PRO GAMER BIOS 2203 - https://dlcdnets.asus.com/pub/ASUS/mb/LGA1150/Z97-PRO_GAMER/Z97-PRO-GAMER-ASUS-2203.zip?model=Z97-PRO%20GAMER
If anyone can help it would be appreciated, I tried to mod it and flash it myself but didn’t have any luck.
Hello @Xerphon o/
Are you able to flash the modified file you made?
Are you able to set Above 4GB Decode, UEFI boot and CSM disabled in the latest BIOS?
If so, adding ReBAR is quite quick. We just need to work on flashing the board if that is the issue?
You are welcome to PM me if you need.
Best Regards,

I was unable to flash the file. I have 4G Decode enabled, UEFI boot and CSM disabled. According to GPU-Z the only thing that is disabled is resizable bar itself.
Hi @Xerphon
Have you tried the methods outlined in the Asus section on this page?
The afuwinx64.exe method seems to work well for me.
The BIOS IC is in a socket, so flashing it via an external programmer is also another option.
Good day everyone, i added the ReBarDxe to my bios, and i can enable rebar etc, but i cant for the life of me patch it to enable larger than 1gb Rebar, i am hoping this thread is still alive and well and that someone out here can help me please.
Il link my modified bios with the ReBarDxe added, and my clean bios with no mods.
Please if anyone can help me it would be awesome
I am using a i7 3770

Hello @Tzuke ,
I can see that the Above 4G Decode is there, it’s just not in the user menu.
You should be able to enable it to get Above 4G Decode working.
If you get stuck, I can help via Private Message. It’s best not to load this thread with a lot of posts back and forth. If you get it working, you can always post a follow up with the details.
Best regards,

Good day,
I managed to get the 4G Decoding working correctly in a way.
I can use 2gb Rebar now and not black screen when rebooting it.
this has made a HUGE difference in cpu usage in some games for me, its insane!
Forza Horizon 5 got a 15% performance bump in avg FPS and much higher lows, and stable latency than before.
Thanks for the guys who found the way to make this work!
Here is a SS of the rebar, address and the card. This is on WIN10 Pro latest updates running and latest AMD drivers from them, not custom drivers or anything extra.
v 24.7.1
IF there is anyone out there on the same Motherboard as me and want to try it out il upload the modified bios. all settings are stock and you will need to re-apply any OC you had and change any settings you had disabled before.

I checked your ASUS H97M-E BIOS mod and noticed there’s a pad between GUIDs AEF82756-87F2-4CF6-BE80-E59055295AA1 and 77840A38-8AB1-4D7A-9181-03B2F5B34C0B.
I have done the Kuri0 mod to an original BIOS 2702, but I am not replicating the pad which you did. All I did, in order, was to add the FFS module, save, and apply the UEFIPatch, and export the body to a ROM. The issue is that I don’t have any means to restore the BIOS should it not work. Hence, I looked at your already applied BIOS mod.
I don’t think DSDT patching is necessary since 4G decoding seems to work without any issue. Did the pad create while reconstructing the ROM/CAP with the DSDT patch, and does your BIOS mod work without issues? This asked what other mods were done to the BIOS?
I want to test this with an AMD Radeon RX Vega 64 and 4 x 8 GB RAM. Just some general questions whether I should proceed with my BIOS mod or with a BIOS mod already tested to be operable?
Sooooo Thanks to @68k-dude and his legendry help i am now able to set my rebar to 8gb on a really really really old i7 3770 system and a Gigabyte Z77X UD5H Motherboard
