If you get ReBAR working please post your system information in the below format
- CPU:
- Motherboard model:
- Motherboard chipset:
- Graphics card model:
- GPU chipset:
- GPU PCI VendorID:DeviceID (check GPU-Z):
- GPU PCI subsystem IDs (check GPU-Z):
- VRAM size:
- New BAR size (GPU-Z):
- New BAR size (nvidia-smi):
- NVIDIA driver ver:
It may be easier to post screenshots instead, with:
- GPU-Z: GPU page + ReBAR page
- CPU-Z: CPU page + MB page
- console output from
nvidia-smi -q -d memory
If you needed to apply more changes to make ReBAR work, post about them as well.

Edited to include CPU model.
Please note GT640 is not supported by nvidia-smi but does appear to indicate full size by other means.
Managed a few tests with 1660S
Why 32GiB? Just to see what might happen if cards maximum was selected, seemed to behave as usual. For other testing usually 8GiB is selected.
3DMark PCIE test results are clearly buggy so not included.
3DMark Timespy showed less than 1% gain with profiles of 1GiB, 1.5GiB so subjective.
Xaler Results
W10 and Linux GravityMark showed no gain, run with Vulkan MS
Gears of War 5 which has been said to be favorable of resizable BAR showed no gain.
Total War Three Kingdoms showed no gain on W10 but did show up to 15% on Linux. The W10 bench scored similar to the resizable BAR score on Linux.
Standard 256MiB
Resized to 8GiB
Unlike W10, Linux nvidia settings shows the resizable flag, note that on my HW it requires resizable BAR to be set at least to the size of the VRAM, so in this case 8GiB and upwards.
With W10, if resizable BAR is set to 8GiB and the card disabled in the OS and resizable BAR adjusted to 256MiB then enabled that the BAR is set back by W10 / nvidia driver to 8GiB.
Under W10 the "nvidia-smi -q -d memory" always seems to show BAR1 memory of 2MiB in use. However under Linux we can see this value change with TWTK showing between 400MiB and 500MiB when running.
Thank you for the report, table updated !
Works great for me, i did wrestle with some of the steps but eventually got there. Might make a video of my own.

Seem like this is one of those games with very clear rebar-size-to-fps-boost ratios :) for testing I repeated them all a few times - clicking continue chapter from where I last saved, letting it load, and doing absolutely nothing. no movement, no adjustments, keeping it controlled. Close game, change NVPI setting, reload. It was consistent, repeatable and I didn't get any FPS fluctuations either so these are authentic snippets.
I am having some issues however - my motherboard BIOS had two identical entries for the PCIE driver to add the .ffs file, and I added it to both. Now my PC will only start from cold, no reboots, no sleep resume, no hibernate resume. It'll not post, and the HDD light will remain on until i power off the PSU and restart. From full power down it works every time.
I have a feeling this might be a potential hurdle for some users as we iron out the kinks of patching compatible BIOSes - I'll do some testing at some point of adding the .ffs to one entry, then the other, and see if ReBAR continues to work and it resolves my issues. For now I can deal with cold boot :P

is anyone else seeing errors in vulkan applications after enabling ReBAR?
I ran into this through the Vulkan Conformance Test Suite on linux
FATAL ERROR: vk.createDevice(physicalDevice, pCreateInfo, pAllocator, &object): VK_ERROR_INITIALIZATION_FAILED at vkRefUtilImpl.inl:249
EDIT: Sorted, was a faulty DSDT patch
Took me a day to get it to work - most troublesome was Gigabyte's "Invalid BIOS" protection.
None of the (modded) tools or how-tos you find will work.
Just use QFlash Plus.
Many thanks @terminatorul
Thanks for adding my configuration! 😁@terminatorul
For completion's sake my driver version is 551.23 and it's a GeForce Game Ready driver.
I don't know what options in NvStrapsReBar.exe populate the Target BAR Size so I just left it blank. 😅
X570 not very easy to flash on ASROCK. I needed to downgrade to old AGESA version and flash modified BIOS using FLASHROM

Can you run nvidia-smi -q -d memory and show the output ?

@SuperCoolGuy855 This is the first time I see option 65 working (which happens to be the safe choice (and least intrusive) if users accidentally disable 4G Decoding or load the default settings in UEFI setup, but the option does not always work).
Congrat'z and enjoy !
I had 65 working too initially but the new version of the program allows me to adjust the BAR size which I needed. 👍
The newer version allows both changing the BAR size on the GPU and using input value 65 for the PCI side.
Please try option 65 and use it if it works for your system (you need to enable ReBAR in UEFI setup) Because it is the safe choice in case you accidentaly disable 4G decoding in UEFI setup, or you load the default UEFI settings, or the CMOS battery dies. So in this case you will not need to manually clear CMOS.
I am thinking of a better failsafe for such cases, but it will be a while before I can implement anything about it.

Option 65 is unavailable for P. Am I looking in the wrong spot for it?
Oh, I forgot I made it the System default.
It's really option 0 now :)

Thank you! Failsafe is now in place and everything is working as intended.
Thank you so much ♥. After fiddling around for a day i finally got it working. In Cyberpunk ~10% increase in performance: 3440x1440p; Ultra; RT Medium, No Upscale.
Since ReBar was introduced i wodered when NVIDIA or someone else would enable it on older Cards. You and xCuri0 finally did it. Thanks again :)
PS: Obviously i don't play at these settings :D
PS 2: In "Adding FFS module" it says to put the *.ffs file at the bottom of the volume. That didn't work for me. Scroll down a little until you see "NvramDXE", "PcdDXE" and the other thing which is too long for me to remember. I put it here on both entries and that did the trick.

Since I activated the BAR thing I can't reboot anymore. The PC will hang after the operating system is powered off, have to press the power button for some seconds and start the pc again.
Also the new Nvidia App (Beta) is not detecting the BAR even after reinstalling the drive completely.

Notes
The 3DMark PCI Express bandwidth test saw a 35% improvement in speed, from ~13 GB/s to ~17.8 GB/s. I enabled ReBAR from nvidiaprofileinspector and set the Size Limit to "0x0000000200000000" to get this result.
Without setting "Size Limit" at all, I only saw minor improvements in bandwidth.

Extra step:
To flash a current modified BIOS, you need to downgrade to a previous version that was less restricted first, then you can upgrade.
Since version F32 (with AMD AGESA ComboV2 1.1.0.0 D) implemented ReBAR, I used it to downgrade and it worked fine.

Happy to report that it also works on the Asrock X570 Phantom Gaming 4 by following these steps (was on previous 5.60 prior, now running L5.61). I did notice an odd quirk where enabling "Fast Boot" does not mark CSM as disabled despite hiding the menu, meaning you may need to check there if you can't enable "Above 4G Decoding".

Afaik someone tried to enable it on Pascal cards, if I remember correctly, it technically enables the larger BAR but on windows the Nvidia driver crashes the system.
So in theory it could work on Pascal cards, maybe with specific drivers, although i doubt any specific driver would work, past one or future one. I have a titan pascal and wondered where the limitation lies.
@Baruls do rebaruefi patches on your BIOS
it will support upto 16gb bar then (unless u have 32gb ram which is then 8gb)
There were no problems during installation.

@osamazakimohammed I'm currently using version 305. Maybe you could try using Intel FPT (you can get it from here) to extract the bios file and then follow the instructions from here to find the setting. Mine is called "Above 4GB MMIO BIOS assignment"

My motherboard supports 4G decoding, so the BIOS could only be updated using USB BIOS FlashBack.
- I modified the BIOS file using UEFITool (https://github.com/xCuri0/ReBarUEFI/wiki/Adding-FFS-module)
- Specified NvStrapsReBar.ffs
- Saved the file and renamed it to the correct name for the BIOS. No need to use UEFIPatch!
- Turned off the PC. Installed Bios via USB BIOS FlashBack
- Launched NvStrapsReBar.exe. Pressed E, S, restarted the PC. According to the instructions.
4G decoding must be activated in the BIOS!
Thanks for the work! Hope this helps someone.

@pexcfequinnet , Thanks for helping , i downgraded my bios and found it , but when i try patching the bios file to add the module , i fail to read it as a bios while updating , can you help me with that ? , probably send the modified one you used , maybe i did something wrong
Downloaded bios from rog website
followed instructions https://github.com/xCuri0/ReBarUEFI/wiki/Adding-FFS-module
had to add it twice (had 2results)
unable to flash bios from within bios
however bios flashback worked perfectly
(also did not need to do anything special for AMD aka downgrade AGESA)
enabled 4g and bar support in bios
used NvStrapsReBar.exe E and S
and rebooted and gpu-z shows it enabled :)

My motherboard supports 4G decoding, so the BIOS could only be updated using USB BIOS FlashBack.
- I modified the BIOS file using UEFITool (https://github.com/xCuri0/ReBarUEFI/wiki/Adding-FFS-module)
- Specified NvStrapsReBar.ffs
- Saved the file and renamed it to the correct name for the BIOS. No need to use UEFIPatch!
- Turned off the PC. Installed Bios via USB BIOS FlashBack
- Launched NvStrapsReBar.exe. Pressed E, S, restarted the PC. According to the instructions.
4G decoding must be activated in the BIOS!
Thanks for the work! Hope this helps someone.
i copied this it worked for me thank you

@osamazakimohammed I'm assuming you are using the EZ flash tool included in the bios to do the flashing, which will not regconize the file as a bios file. There are two ways you can flash the modded bios: either through Intel FPT or using an external programmer like the CH341A. As for my modified file, I have lost it while doing a OS reinstall so I will have to recompile another one.
Edit: you may have to dump the bios into a file using Intel FPT or an external programmer and then patch the file from there instead of using the bios file listed on the manufacturer's website
i keep getting update failed wrong image format 11, is there any way to flash modded bios for msi?
Went by the book. Used the Asus Bios Flashback or whatever it's called. Not a hitch. The CPU is Intel i9 13900k.

How did you manage to flash the BIOS? The official BIOS files provided by Lenovo seem difficult to modify. If you were able to modify it successfully can you share your method please?

You are the second Lenovo laptop user that I've noticed have managed to successfully flash BIOS. It seems very difficult to impossible to modify the BIOS file, so how did you get around this?
You are the second Lenovo laptop user that I've noticed have managed to successfully flash BIOS. It seems very difficult to impossible to modify the BIOS file, so how did you get around this?
For the Legion 5i 15IMH05H, there are several BIOS revisions with an EFI variable that, when deleted/disabled, unhides the Advanced section of the BIOS. Mine is on EFCN52WW, if I remember correctly, the latest version with the variable. I unlocked the BIOS to get into the Advanced section and disabled both FPRR and BIOS Lock. I dumped the BIOS using Intel FPT. I followed the guide here (and ReBarUEFI), then flashed the patched dump using FPT again.
For anyone looking for how-tos that might be relevant to them, here is my experience:
- The BIOS/UEFI version you see here already includes Above 4G Decoding and its own ReBAR support (Clever Access Memory in ASRock's terminology), both of which I had already activated.
- After a bit of research, I decided to work around ASRock's Secure Flash protection via Intel FPTW instead of Flashrom. Out of convenience, really.
- I found out which CSME Tools version to use for this chipset (11.8 Consumer H D,A) on the Win-Raid forums. I then dumped only the BIOS region as per advice I read there:
fptw -bios -d original.bin - I modded the dump according to the guide while leaving out UEFIPatch. I believe it's not necessary, because the board is new enough, but I'm not fully sure about this. It seems to work regardless.
- Then, I flashed the modded file like this:
fptw -bios -f modded.bin - I rebooted and followed the guide again. NvStrapsReBar.exe now shows GPU-side ReBAR Configured with PCI confirm (0x0100000000000064).
A big thanks to @terminatorul, @xCuri0 and everyone on Win-Raid!

I just installed FPT, but I'm not very familiar with this tool. What command did you use to dump the BIOS? I used "FPTw.exe -bios -d biosreg.bin", but when trying to search through the file in UEFITool there is no modifiable address to add the .ffs file to the dumped. So I'm not sure if I actually dumped the BIOS, and then once I finish that step what is the FPT command to flash the modified dump back onto MOBO?

Yes, that is the right command to dump the BIOS. I used Unicode text search and searched for PciBus instead of the GUID and hex pattern. There should at least be one result. Insert after the result(s) that is/are not in the padding.
To flash, FPTW -bios -f <patched dump here>.bin. If done right with FPRR and BIOS Lock disabled, it should proceed to flash.

One other thing, in the instructions it says that we need to place ReBarDxe.ffs in the BIOS image, but NvStraps requires the NvStrapsRebar.ffs file instead. It doesn't seem clear if we need to add both, or just NvStrapsRebar.ffs because both come included in the NvStraps folder.

Just NvStrapsRebar.

Hello @rainbowjose ,
I have pretty much the same config (I5 9600KF/Aorus Z390 pro/2070super).
I have inserted the nvbar ffs file in F13 bios, but I got the error “Invalid BIOS image” with Qflash...
Did you got same thing and how did you get rid of that ?
I tried to grab some info on https://winraid.level1techs.com/t/flashing-gigabyte-while-avoiding-invalid-bios-image/31185/373, which method worked ?
Did you tweak something else on bios file ?
Thanks !

Thank you for the mod, works great! In order to update the modified BIOS I had to use the Q-Flash Plus method with this board. Now lets just hope that Nvidia doesn't somehow prevent this mod with a future driver update.

So I attempted to flash the patched ROM file for the BIOS, and it appears that I must have incorrectly done something in the process as my laptop is stuck on boot after restarting. I have to reflash the BIOS, I'm not sure what I missed as I made sure I followed as closely as possible. Were you able to get it on the first try, and do you happen to know how to reflash the BIOS for our MOBO?
Solution is pretty simple: i was just downloaded patched flash utility, where integrity check was removed, and flashed with it. And also i reccomend use F11, because there is new type of bios come in F12 so it is consedered as experiment that not worth 3% speed increase. You also can easily downgrade your bios to F11 with another utility that you can find easily. With all due respect to you and your obviously positive desire to make your computer and hardware more efficient, I'm not sure you should do this without reading more deeply and immersing yourself in the issue, because completely silent, bricked computer is such painful thing.
…
Thanks for your quick return and your advice @rainbowjose
I have upgraded earlier to F12 because of patching vulnerabilities and the availability of the ReBAR option...
The modded EFIFlash tool can be used from MS-DOS or UEFI shell, what did you use ?
It could be safer to only flash the main bios, but it may be not easy to recover it from the backup on our board... even with the dualbiosrescue utility, but never had to use it.
I will wait for someone else achieve it with F12 or F13 bios.
