There are warning beeps (1 long and 3 short) at startup and black screen due to Windows login screen (possibly to start GPU driver). But no any other errors or issues at all, ReBAR works perfectly. |

Would my Z97-Pro be considered working? I haven't tried the 16GB patch (only tested to 8GB), but it needs the replacement of the older 1204 NvramSmi module and the PciBus UEFIPatch to work. The GPU tested is the Intel Arc A380 (will test the A770 once I get a replacement power supply).
@Tokobotenkai anything 4GB or higher is considered working but if you find a larger size doesn't I can add a note
Hi, i have z270 m7 with 7700k. my motherboard has 4G decoding in bios. i also have gtx 1080. how to patch my bios?
here my bios link:
https://download.msi.com/bos_exe/mb/7A57v10.zip
@sidex15 But can you actually check what a name of this board?, im trying figure out how to patch mine X79, checking whats the difference between them, maybe i will find something. Or even better, save a bios file, and upload here.
@aquamacho1
well after deep diving in the russian overclocking forums I found that my board is Jingsha X79M-S 1.0 the Picture is the same as mine...
I just followed the X99 guide from Miyconst and use Enabling hidden 4G decoding...
@sidex15 This is awesome, thx. I will just buy this mobo then :), im just kidding.
@sidex15 I think macOS doesn't support large BARs not a problem with the bios or anything
@sidex15 I think macOS doesn't support large BARs not a problem with the bios or anything
Yeah i'm using opencore 0.8.3 even with resizeapplegpubars set to 0 won't even boot to macOS...
I guess it's still using the max BARs...
I'll try lowering the BAR size see if it boots...
MZ32-AR0 (rev. 1.0) +ARC A380 +TESLA M40
Before:
(A380 has a 43 code after installing any driver later than 31.0.101.3277 on my platform. I don't know why Tesla M40 has "large memory range" by default. Does that mean there is a white list inside the bios for some rebar cards? )
After inserting ReBarDxe.ffs and running ReBarState.exe BAR size set to unlimited :
(A380 works with the latest driver after doing these. A small issue i found is that Intel® Arc™ Control refuse to start. )
I can confirm it works on a Supermicro H11DSi-NT (tested with bios v1.3, should work with the v2.4 as well). Tested with a 4090 FE. No patches needed, 256GB ram installed.
GPU-Z says 3 bars are available - 16MB, 32MB, and 32GB. (before it was 16,32,256MB, and it said "disabled in bios")
Thanks a lot for making this tool.

I suspect it is some device being mapped in the same error, but the error is intermittent. I workaround it by using a PS2 keyboard.

Asus Z170-P D3 : requires patch "Don't downgrade 64-bit BARs to 32-bit (by @Mak3rde)"
@xCuri0 I found this:
LongSoft/UEFITool#116 (comment)
842A454A-75E5-408B-8B1C-36420E4E3F21 10 P:9801000072:0000000072
Vit9696's code allows for nvramsmi to write on UEFI for Z97's Asus motherboards like my Maximus VII hero. Already tested it, and it works.
Saved me from extracting nvramsmi from 1104 and replacing it on 3503.
So I've modified my Asus Z97 Deluxe bios with FFS DXE module, then patched it with those patches: # NvramSmi NVRAM whitelist unlock (by @vit9696) and # PciBus | Don't downgrade 64-bit BARs to 32-bit (Haswell).
All successful, flushed bios - it loaded. Enabled 4G Decoding and disable CMS. Although I'm not sure if some ReBar option should appear in bios menu as well? Because it doesn't.
But after using ReBarState.exe and setting value to 32(also tried 16) mobo won't boot after I restart it. At first it makes singe beep with pc-speaker as if its OK, but after 2 seconds there goes another 3 beeps and thats it. Any suggestions?
@Divin1ty666 No, you shouldn't see any options for ReBar. Once you've set your Rebar Value, you should aee it in GPU-Z.
If you can't get into windows, then that's because you jumped to a high value than to try smaller values to see which one is more stable. Try clearing CMOS, if that doesn't work, disconnect your GPU (Removing power cable from it should suffice), then connect your display cable into your motherboard if it has that option and reset the value to something smaller.
You didn't mention how much ram you have installed. If it is 16-24GB use this patch too:
# PciHostBridge | Replace 8-16GB MMIO region with complete use of 64GB address space (Haswell).
If you are at 32GB, it won't work as it needs further modification. I have mine working with 16GB rebar at 24GB of ram. I guess I'll open a new thread today so we can see if we can fix that 32GB.
Here are the patches I've used:

The "norm" is to have 1 beep after the normal post after you set the rebar value. There will be an issue of USB not working in bios. So set your overclocking, rebar, csm before applying the value of rebar. It'll mess with entering safe mode of windows too, check my win-raid post for guides to workaround it if you need it.
@cursemex I have 16Gb, but # PciHostBridge | Replace 8-16GB MMIO region with complete use of 64GB address space (Haswell). patch cannot be applied: No patches can be applied to input file, all other patches are applied already.
@Divin1ty666 what's your GPU ? If it's a 32GB BAR such as 3090 it won't work even with 16GB RAM
@Curi0 rx 6700 xt
@Divin1ty666 do smaller bar sizes atleast work ? start with 512mb and increase till you get the issue
@Curi0 So should I start with "1"? Or what value should enter for 512mb? I don't get I how they correspond, I know 0 means disable and 32 is max, right?)))
ps. and what about patch PciHostBridge | Replace 8-16GB MMIO region with complete use of 64GB address space (Haswell) - do I need it? Or it's not for z97 motherboards?

This is in terms of power of 2, as in 2^x. In this case, two to the power of eight would be two hundrend and fifty six. 2^8 = 256MB, therefore the value we put in ReBarState.exe should be 8. For 512MB it'll be 9, 1024MB will be 10, and so on.
@xCuri0 can confirm that ASUS X99-DELUXE II works with Intel A770 with 16GB BAR0!
Required the Nvramsmi patch! Thanks again for putting this together :)
@Intelevande did you need to use UEFIPatch ? all other Z97 users had to
@Intelevande did you need to use UEFIPatch ? all other Z97 users had to
I didn't use UEFIPatch, I followed your instructions on inserting the FFS and enabling the hidden 'Above 4G Decoding' option, set 32 in the rebarstate.exe program and it seemed to be working for me. Do you think I should expect some issues even though gpuz says it's enabled?
Edit:
I guess I should also note for anyone else who has my board the offsets for 4g decoding and csm that I used
Above 4G Decoding: 0x1
CSM: 0x596
Hi everyone, I ran into a problem when using UEFI Patch. When trying to apply patches.txt PowerShell writes a message 'patches.txt file not found or can't be read'. UEFIPatch, UEFITool 0.28.0 and patches.txt are located in the same directory.

Use Command Prompt with admin privilage instead. You can search up CMD in the task bar search, then right click it and run as admin.
Then "cd [UEFIPatch.exe directory]".
And follow the rest of the instructions from here. Make sure to use "UEFIPatch.exe [filename] [patches.txt] -O [output file]" during the commands with the ".exe" included in the command.

@LordAdo96 do you see the name of this issue? It's "List of working motherboards", not "Support for people who don't understand a thing".
@xCuri0 I think with rising popularity such people will swarm this repository. Maybe redirect them somewhere?
@SEt-t i do think that's starting to be a problem but i don't know where they can create support questions. maybe github discussions or setting up a discord ? i also can't be responding to all of them

@xCuri0 I'll be down to help with a discord. I was on the verge of writing a dummy's guide on patching, or just refer them to my winraid step-by-step.
@LordAdo96 You already opened an Issue, I'll just reply there.
My bad sorry guys really
@cursemex already made a dummy's guide on patching including the MMTool workaround. It's on the wiki linked in README

So, I tried entering values 8-10-12 in ReBarState with modded bios and mobo(asus z97 deluxe) booted, but usb keyboard don't work until I re-plug it in. So I can't get into the bios . Thing is GPU-Z says Resizable Bar enabled in bios - NO other requirements are YES. What do I do?((
@Divin1ty666 does GPU-Z show the BAR size has increased ?
@Divin1ty666 update your GPU-Z. Old version probably has incorrect detection and doesn't show BAR size
And you need the 16GB limit patch for 16GB BAR to work. 6700 XT has 12GB of VRAM which uses a 16GB BAR. Note that 16GB BAR won't work if you have 32GB of RAM installed
@xCuri0 I've tried patch # PciHostBridge | Replace 16GB MMIO region with complete use of physical address space (Ivy Bridge). MAY REQUIRE DSDT MODIFICATION - cannot be applied, it says No patches can be applied to input file. Perhaps I'm trying wrong patch, could you please tell me what exact patch should I use?
@Divin1ty666 Remove <16GB BAR size limit (Ivy Bridge/Haswell)
That patch I've applied successfully already
Here is list of patches I've applied:
PciBus | Remove <16GB BAR size limit (Ivy Bridge/Haswell)
PciBus | Don't downgrade 64-bit BARs to 32-bit (Haswell)
NvramSmi NVRAM whitelist unlock (by @vit9696)
@Divin1ty666 how much RAM do you have installed ? any additional PCIe cards or dual GPU ? I don't see why 16GB won't work if you have less than 32GB RAM. And send screenshot showing large memory in device manager view -> resources by type
I have 16Gb ram, I do have Creative SB X-Fi Titanium HD soundcard, but i've unplugged it for now to be able to get to bios socket). My cpu is not haswell though, its broadwell(5775c) but I think it doesn't matter...
@Divin1ty666 did you try the PciHostBridge | Replace 8-16GB MMIO region with complete use of 64GB address space (Haswell). MAY REQUIRE DSDT MODIFICATION
patch ?
Yes, I have. Same thing - it can't be applied.
@Divin1ty666

Hm, that one worked, gotta try that bios now with 14 value, thanks!
ps that patch is not in the patches file, is it outdated btw?
So 16Gb working now. I do have strange readings that my VRAM load is now >13Gb in HZD. FPS boosted by 15 I think, although in benchmark it has dropped because CPU load there has now become 90%+))) In game CPU load has increased as well but it's not critical at least.
Also I no longer can access bios because USB initialize only after bios post screen... Can anything be done?
So I guess you can add my result to the list, again its Asus Z97-Deluxe Wi-Fi + RX 6700 XT
@Divin1ty666 will make a proper patch for it and then add it to the list. if you can test the proper patch when it's made it would be helpful
@xCuri0 You mean patch for USB issues?
@Divin1ty666 you have to do all your bios modifications BEFORE applying the ReBarState.exe value, that's where the USB issue starts. The same issue will happen when you try to get into windows safe mode, you won't be able to due to undetected USB. If you need to get into safe mode, use msconfig(From task bar search bar) to be able to boot into safe mode, and use it again to boot normally.
@Divin1ty666 try this improved pci allocation unlikely but could fix the usb issue

@Divin1ty666 you have to do all your bios modifications BEFORE applying the ReBarState.exe value, that's where the USB issue starts. The same issue will happen when you try to get into windows safe mode, you won't be able to due to undetected USB. If you need to get into safe mode, use msconfig(From task bar search bar) to be able to boot into safe mode, and use it again to boot normally.
After finishing the BIOS on my end, I can't get my keyboard detected most of the time though sometimes the keyboard works. I just plug in a PS2 keyboard or use a PS2 to USB adapter.
@Divin1ty666 I am waiting for my 5775C too, hoping to disable the onboard GPU so that the CPU gets access to the eDRAM memory (maybe a 5800x3D of its time?). Getting 2400MHz CL10 DDR3 does give significant performance in 2022 unlike back then.
With rebar on 5775c(4.3ghz cores, 3.9ghz ring, 2.2ghz L4) now bottleneck in games where rebar is actually working, so 5775c won't help you, nor will ddr3 2400 cl, cos that whats I have. It just lacks cores, nothing can compensate for that.
https://valid.x86.fr/ulelg7 - single thread perf is almost 550 with 3.7ghz cache
Yes, I know, thus, it is a test machine (for fun), it would be worse with the original 4690k inside and 1600MHz DDR3. Probably need an overclock for both the CPU and eDRAM.
L4 cache there is not a HBM module
L4 cache there is not a HBM module
My bad, it is eDRAM. Edited.
Works with ASUS Z170-DELUXE+Intel Arc A380
I modified the 3801 bios based on @dsanke‘s mod to support 9700KF, just insert ReBarUEFI and patched PciBus with MMTool, flash bios and set BAR size to unlimited.
Must enable 4G Decoding and disable CSM on first boot, or your'll get a vga debug and not boot.
Tested with 3DMARK Timespy, before:
So it works!
@xCuri0 Would Github support the file upload of the BIOS? Not sure a collection of working patched BIOS would be useful for anyone stumbling on this thread (though I don't know if there's any licensing issues).
@Tokobotenkai GitHub lets you upload upto 25mb in comments so I don't think uploading is an issue. Not sure about licensing though.
I think it's not a good idea to upload your modified BIOS. What for? For people who can't do the modification themselves? They would brick their system even more likely this way. And yes, licensing is probably not an easy issue.
What is very useful and greatly appreciated is collection of patches. I'd say tutorial + explained patches are the best way to go.
Hey, I've been added to the list but my mobo is Z97-Deluxe, not Z97-PRO :))
@Divin1ty666 thanks I've fixed it
Works with ASUS X99 DELUXE+RTX 3080Ti

flash bios Koekieezz and set BAR size to unlimited.
X99 DELUXE, it's working!!! I modded it for version 3802

Hi, i have z270 m7 with 7700k. my motherboard has 4G decoding in bios. i also have gtx 1080. how to patch my bios? here my bios link: https://download.msi.com/bos_exe/mb/7A57v10.zip
I just did that with 7700k z270 m5 and 3080ti and it's working
@triple-octopus did you have to use uefipatch ?
@triple-octopus did you have to use uefipatch ?
I will share the full process and I'm thinking about making an article to make it simple for people.
but first i need to know how to check my bar size? i set it first time to 8 gb and it worked then i set it to 16 and the pc worked and then i set it to unlimited and the pc works and games work. does that mean that it's set to unlimited because gpu z shows
Bar0 16MB
Bar1 16384MB
Bar2 32MB
@triple-octopus unlimited just uses the maximum size supported by the GPU which in this case is 16GB
@xCuri0 Hi there
Thanks for your hard work!
I have a question - is it possible to implement Don't downgrade 64-bit BARs to 32-bit patch for my Gigabyte board, H310M S2 2.0 specifically? Sadly, I can't go past 1Gb BAR limit - system boots, but displays no image, thought this patch could solve this issue.
Thanks!
@triple-octopus did you have to use uefipatch ?
Yes
@somexhey does uefipatch with the provided patches.txt not find anything to patch ?
also I see some people with similar motherboards say 4GB and larger BARs work while 2GB doesn't

It sucessfully applies Remove <64GB BAR size limit patch, but not a Don't downgrade 64-bit BARs to 32-bit one
I tried to do 4Gb and more, but no success there too
@somexhey don't see the GPU. It has to show the address the GPU is allocated at. The resources tab of the GPU will show it
