Since things are a little complicated with a lot of threads spread all over the place, I'm going to post all the relevant BIOS information we've given to people. If you don't see a BIOS you need, you can request it below. However, I'm making this thread mostly to inform people about some of the issues people run into when flashing their BIOS or having to update the MCU via Precision X1, so new BIOS additions will be a lower priority.
PSA#1: TURN OFF "FAST BOOT" IN YOUR MOTHERBOARD BIOS.PSA#1: TURN OFF "FAST BOOT" IN YOUR MOTHERBOARD BIOS.PSA#1: TURN OFF "FAST BOOT" IN YOUR MOTHERBOARD BIOS. Longer PSA in spoilers.
I strongly suggest that you read this at least once. It could prevent an RMA. Seriously.
Spoiler
Once again, turn off Fast Boot in your motherboard BIOS while you're playing around with flashing your BIOS. If fast boot is enabled, Windows will treat your card as the same GPU unless there's an obvious change, such as you change from a GeForce RTX 3080 to a GeForce RTX 3090, for example. Otherwise, Windows will just assume that nothing in your system has changed, including the DeviceID, which will change when you flash to a different BIOS version. Because Windows doesn't update the information automatically, it will give Precision X1 the wrong information, which is how many of you have run into an MCU flashing issue. If fast boot is disabled, Windows should check the DeviceID of each hardware component during each boot. It's still worth it to restart a couple times after flashing or flipping the switch over to a different BIOS to make sure everything is working normally.
So, please make sure to turn off Fast Boot until you are done flashing, and you've decided on which BIOS switch you want to use. At that point, you can restart and re-enable Fast Boot again, if you wish.

PSA#2: DISABLE CSM IN YOUR MOTHERBOARD BIOS BEFORE FLASHING A REBAR BIOS. Longer PSA in spoilers. If you forget to disable CSM in your motherboard BIOS before flashing a ReBAR BIOS, then you may end up with a black screen upon your next boot. If you need to learn how to enable NVIDIA Resizable BAR, visit our FAQ:

Spoiler
Disable CSM in your motherboard BIOS, or you run the risk of getting a black screen at boot. For FTW3 cards, which you can flip the switch on the card to go to a non-ReBAR BIOS, you can quickly fix this and get picture again. However, for those of you with an XC3 card, you only get one BIOS, and it will likely lead to an RMA if CSM is not disabled.
Note - It's true that you could run into some issues with booting into your OS or legacy hardware if you disable CSM. However, you can resolve those issues by re-enabling CSM. If you discover that you have an issue when you disable CSM, it's far better to learn what you need to do to fix those issues
before you flash your card to an unrecoverable state. Plenty of people on this forum can help you figure out what you need to do to get your system ready for Resizable BAR.
Lastly, some cards originally ship with a Resizable BAR BIOS, and newly built 30 Series cards will also ship with a Resizable BAR BIOS. The list of cards that began shipping with a ReBAR BIOS include:
- EVGA GeForce RTX 3090 KPE HYDRO COPPER
- EVGA GeForce RTX 3080 Ti (all cards)
- EVGA GeForce RTX 3070 Ti (all cards)
Additional Notes:
- For each XOC BIOS, I'm only going to post the ones with Resizable BAR. I don't currently have access to all the original XOC BIOS (thanks Jacob), and it would take time to procure them.
- If the included .exe files are not clear about which is the OC or the Normal BIOS for FTW3 cards, I will list which file is which.
BIOS Instructions (Windows Installation):- Disable Fast Boot in your motherboard BIOS
- Download the correct .zip file below for your graphics card below.
- Extract the files to a location on disk.
- Make sure no programs are running in the background, and double click Update.exe
- Press "Y" to begin the update.
- DO NOT TURN OFF POWER OR RESET DURING THE UPDATE PROCESS!
- After update, restart PC.

BIOS Flashes for EVGA GeForce RTX 3090 cards
EVGA GeForce RTX 3090 Cards have several different versions. Please pay close attention to which cards you have before installing a BIOS. Although most of these BIOS versions won't cause problems if you flash between them, if you have a 3090OC card or a more newly manufactured 3090 FTW3, or 3090 FTW3 ULTRA, or 3090 FTW3 HYBRID card, then you already have the XOC BIOS on your OC switch.
How to tell if you have a 3090 OC card and why it matters:
Spoiler
Before flashing your BIOS, confirm which type of card you have. Because of some differences between the cards, flashing the wrong BIOS to your card could impact performance. Here's how to tell the difference:
- You emailed EVGA Customer support using the 3090OC email, sent in your card for RMA, and received a new card as a replacement.
- You've more recently purchased an EVGA GeForce RTX 3090 FTW3 card (FTW3/FTW3 ULTRA/HYBRID). Here's a couple ways to check:
- Move the BIOS Switch to OC, then check the BIOS via GPU-Z. If the maximum wattage is 500W, then you have a 3090OC card.
- Check the DeviceID in GPU-Z or PX1. If you see near the "3842", the 3090OC cards will say "3981" for FTW3, "3982" for FTW3 ULTRA, and "3983" for HYBRID.
