Wouldn't be surprised if all AIB's took advantage of this BIOS release to tune down BIOSes to alleviate RMA's, especially from potential GDDR6X failures. *Tin-foil hat on
 
"If your VBIOS version is:
F1, it can only be updated with VBIOS versions F2-F9.
F10, it can only be updated with VBIOS versions F11-F19.
F20, it can only be updated with VBIOS versions F21-F29."
You can see your version in GPU-Z. Advanced -> drop-down menu NVIDIA BIOS

I wonder if it's still fine to flash a BIOS from a different model. Currently i have an Eagle OC card with Gaming OC BIOS. Now they actually have 2 different files, one for flashing the OC BIOS and one for flashing the Silent BIOS.
Please keep us posted on if successfully get up and running on a resizable BAR BIOS.
 
Yes, it's working just fine. Updated motherboard BIOS, enabled "4G Decoding", set "Re-Size BAR Support" to auto, disabled "CSM Support", flashed the F22 Gaming OC "OC BIOS" on my Eagle OC and then updated graphics drivers.
Where did you get the F22 Gaming OC "OC BIOS? How did you flash it?

Did you just use the file from the Gigabyte website? I thought that file would try to flash the DUAL bios since the Gaming OC has DUAL BIOS while Eagle OC does not.
 
Guys i have an msi gaming x tri o 3080. I flashed a strix 450 watt bios and it works perfectly. Now i want to update to the latest vbios with rebar support for strix. is it safe flashing this new bios with nvflash using the same old method in page 1 of this thread or do i need to use an updater tool. Have anyone flashed a different bios like strix rebar bios on msi 3080?
 
I have a Gigabyte Vision OC RTX 3080, the Resizable BAR BIOS update seems broken for me.

The first thing that caught my eye was the sheer number of different BIOS versions for the RTX 3080 Vision OC, there are 6 in total (F3, F12, F21, F31, F51 and F80). A note below states:

Please note:
You can only update to a VBIOS version of the same series.Visual C++2008 is required for this BIOS flash.
If your VBIOS version is:
F1, it can only be updated with VBIOS versions F2-F9.
F10, it can only be updated with VBIOS versions F11-F19.
F20, it can only be updated with VBIOS versions F21-F29.

So great, I get into GPU-Z to check my BIOS version, and this is what I find:
BIOS Version 94.02.26.80.3C

So I don't know what BIOS version I have. As it turns out, you must download Gigabyte AORUS Engine to find out your BIOS version (but they don't state that anywhere in the website), mine was F1. So for me, the update is the F3 BIOS.

I downloaded the new F3 BIOS (Resizable BAR) from the website, extracted the zip file. Once I try opening the N3080VO.F3.exe file, after going through Windows safety protocols, a window asks "Are you sure you update your Graphics BIOS?" (this isn't a typo), I click "Yes" and get the following message:

Windows cannot find 'C:\Users\xxx\AppData\Local\Temp\N3080VO.F3.exe'. Make sure you typed the name correctly, and then try again.

So I tried to manually extract all the files directly to the mentioned folder, this eliminates the error message, but the application gets stuck in "Are you sure you update your Graphics BIOS?" window. I click on "Yes", nothing happens and the window just comes back on, asking me the same thing. So I click "No" to get out and, eerily, I get a "Flash BIOS success ! Would you reboot the system ?" (again, no typo). I can click "Yes" to reboot my system, but obviously, my card hasn't really been flashed, it's just the buggy update software.

Apparently, other Gigabyte owners are flashing their cards with no issues, so it's either something in my machine, or maybe just the specific 3080 Vision OC F3 BIOS that's messed up. Unlike flashing through NVflash, the Gigabyte software won't allow you to flash any other BIOS version that isn't directly compatible with the one you have. So I'll either have to flash my Vision OC with some other BIOS (say, Gaming OC BIOS) through NVflash, and then try updating the card this way through Gigabyte's software, or I'll just wait for the correct Resizable BAR version of my BIOS to show up in the BIOS database and flash it through NVflash. I also do not know how to extract the BIOS file from Gigabyte's executable to be able to upload it straight to my card through NVflash, othwerwise I would just do that.

If anyone knows a workaround for this problem, please give me a heads up.

GeForce RTX 30 Series Performance Accelerates With Resizable BAR Support
By Andrew Burnes on March 30, 2021 | Featured StoriesGeForce RTX GPUsHardwareLaptops
Resizable BAR utilizes an advanced feature of PCI Express to increase performance in certain games. As of March 30th, 2021, Resizable BAR is supported for GeForce RTX 30 Series graphics cards and laptops.
For desktops to take advantage of Resizable BAR, users need a GeForce RTX 30 Series graphics card with a supported VBIOS, a compatible CPU, compatible motherboard, motherboard SBIOS update, and our newest GeForce Game Ready driver.
For GeForce RTX 30 Series laptops, please check with the manufacturer to see if Resizable BAR is supported on a specific model.
For instructions on how to enable Resizable BAR, continue reading.

What Is Resizable BAR?
Resizable BAR is an optional PCI Express interface technology. As you move through a world in a game, GPU memory (VRAM) constantly transfers textures, shaders and geometry via many small CPU to GPU transfers.
With the ever-growing size of modern game assets, this results in a lot of transfers. Using Resizable BAR, assets can instead be requested as-needed and sent in full, so the CPU can efficiently access the entire frame buffer. And if multiple requests are made, transfers can occur concurrently, rather than queuing.



Installation Steps
To successfully activate Resizable BAR on a desktop PC, please follow these steps in order, referring to the expanded installation instructions below:
  1. Confirm you have a compatible CPU & CPU chipset (see list below)
  2. Confirm you have a compatible motherboard (see list below)
  3. Update your motherboard SBIOS, if required, by installing an update from the manufacturer. Then enable Resizable BAR support in your motherboard’s BIOS interface
  4. Update to the latest GeForce Game Ready Driver (version 465.89 WHQL at the time of writing, released March 30th, 2021), or a later version
  5. If you have a GeForce RTX 3060, you’re good to go. If you have a GeForce RTX 3060 Ti, 3070, 3080, or 3090, then you may require an updated VBIOS
  6. If you have a Founders Edition graphics card from NVIDIA, get your VBIOS update tool directly from our website. If you have a custom partner card, get the update tool from their site (see list below)
  7. Verify Resizable BAR is enabled in the NVIDIA Control Panel (see instructions below)

What CPUs and CPU Platforms Support Resizable BAR?
Resizable BAR requires CPU and motherboard compatibility, and a Resizable BAR SBIOS update. As of March 30th, 2021, the following CPU chipsets and CPUs officially support Resizable BAR on GeForce RTX 30 Series desktop GPUs:

Desktop CPU and Chipset Support

Motherboard Support
NVIDIA is working with motherboard manufacturers around the world to bring Resizable BAR support to compatible products. As of March 30th, 2021, the following manufacturers are offering SBIOS updates for select motherboards to enable Resizable BAR with GeForce RTX 30 Series desktop graphics cards:

Motherboard Manufacturers Supporting Resizable BAR
ASUSASRockCOLORFULEVGAGIGABYTEMSI
Head to the manufacturers’ website to discover whether your motherboard is compatible, and to download and install updates if available. Additionally, please refer to the manufacturer’s documentation for enabling Resizable BAR support in the BIOS after installation of new firmware.
Please note, some motherboard manufacturers have unofficially extended Resizable BAR support to prior generation products. Your mileage may vary utilizing these solutions.

Enabling Resizable BAR On Your GeForce RTX 30 Series Graphics Card
Having updated your motherboard, you’ll need to update your GPU, and download and install a GeForce Game Ready Driver, released March 30th, 2021, or later.

Game Ready Driver Update
In practice, the performance benefits of Resizable BAR can vary substantially from game to game. In our testing, we’ve found some titles benefit from a few percent, up to 12%. However, there are also titles that see a decrease in performance, so NVIDIA will be pre-testing titles and using game profiles to enable Resizable BAR only when it has a positive performance impact. That way you won’t have to worry about bugs or performance decreases, and won’t have to rely on the community to benchmark each title and discover whether Resizable BAR is beneficial in the games you’re playing.

I've just updated my RTX 3090 Suprim X to the latest VBIOS which enable resizable bar on my Gigabyte Aorus Ultra Z390. Yes, I said that right, Z390 using an i9 9900K. Nvdia said that this only applies to the newer 10th and 11th gen Intel CPU's, but thats crap, as my motherboard had a resizable bar option added months ago, when I was still rocking my 5700XT. I have verified that this is now working, as I have the large memory range listed in device manager for the display adapter. Woo hoo, for one more FPS during gaming!

I am using a strix bios on my msi gaming x. i cant just do a direct vbios update. i want to flash an updated strix bios with rebar support but i am worried it might screw things up since it is an msi card using an older strix bios.

By now, I think people realize that NVidia means they will only support ReBAR issues with 10th and 11th gen Intel CPUs.

It seems a lot of people are claiming lower power levels after the ReBAR BIOS update. Apparently, vendors are using the opportunity to silently decrease the power levels of their cards. Maybe an attempt to control the elevated GDDR6X temps? Either way, this seems like a bummer, losing 100-120Mhz core clock speeds in average seems worse overall than any possible performance gains ReBAR might give in the handful of games they actually work with.
 
Hi, Guys, I'm new in the community. I have an MSI RTX 3080 Gaming Trio and I would like to "shunt mod" and Flash the Bios to make the most from the card. I would like to hear from you if it worth it.
I'm building a water loop with big radiators to keep the temperature down. I would love people to advise me. What's the performance gain if I do both things "shunt mod" and "Flash Bios"?
Do you guys know about a Flash tutorial?
Please I would like to hear an opinion from people who know about overclocking and who like to overclock. Thank you People
