How can there be so many 420w-500w (XOC) BIOS out there for the same card (3090 FTW3 Ultra)? See mine below. Only reason I can think of is that your card (@slapn) isn't a replacement card from the RMA program and you still own the original one. Otherwise...I really don't know. But they're working... Still, I can't wait for an official release - if such thing ever happens. It would be nice to know you have the latest and greatest. @slapn, I tried to flash yours (from TechPowerUp) and it gives me an error and we have the same card -and both are for Resizable BAR.

Just wondering if this is/will be supported on X299. I currently have an X299 FTW K motherboard, and I know that EVGA released a BIOS update for X299 boards earlier this year that added resizable bar support to the PCIe bus, but NVidia doesn't currently list X299 as a supported platform for resizable bar for their GPUs.

I'd like to know what happened to the fix for the fans on the 3080 FTW3 Ultra... was supposed to be fixed last week and never happened.

So I tried to flash the 3080 FTW3 Ultra 450w 'normal' bios to a hybrid using the evga provided .EXE in an attempt to get 0% fan speed control. It kicks out for not being a compatible card.  Before I go messing around with the unlocked NVFlash and bios files, can anyone confirm that the newest 3080 FTW3 Ultra 450w (xoc) 'normal' rebar bios has 0% speed on all the fans?

It does not do 0% on OC bios now. Jacob told me personally on Twitch we would have a fix last week. It is still broken with this bios.

Hey thanks.  Just to be clear, the 'normal' xoc bios?  Thanks!!
 
The fans I want to run go 1680 rpm at 30%, so that's a bit of a high idle.  Will do 1000 rpm at 0%.

I don't have a Hybrid. But on mine I can't drop below 33% with this bios on the OC side. The non overclock bios is fine. But I would not flash the OC bios to your card with it having a hybrid kit with this fan issue.

Hey thanks.  The FTW3 OC switch bios is always supposed to have a non-zero fan speed, on the 3080 Hybrid it's 44% minimum.  It's so when you crash the PC/GPU or reset the OC software the card always comes on with at least some reasonably high fan speed. 
 
So you're saying you've got the 3080 450w Rebar bios 'normal' switch position and it can go 0% on all three fans?  Because some people were posting pics and saying it would only go down to 33% on the first two fans.  Thanks!
 
I've got a straight up hybrid card btw, it was never an Ultra, hence the .exe flash not working as it checks the card model.

The normal bios is fine it goes to 0 like it should. It's the overclock bios that is messed. Only one of the 3 fans can go to zero the other 2 can't be forced off. I have seen mine at times with OC bios start up with one fan not running. Personally until it's fixed I wouldn't touch it with a card that was hybrid.

 
That's totally normal behavior for all OC switch position bios, they aren't going to change that.   If anything they would fix it so all three fans run at 33% minimum.

Did the latest MCU firmware/Re-BAR VBIOS disable fan spin down on the 3080 FTW3 Ultra?

I have the OC switch XOC Re-BAR VBIOS flashed and I can't seem to set anything below 34% on fan 1 and fan 2. Fan 3 does spin down when using Precision X1, but not when I'm using MSI Afterburner.

Before updating to the latest MCU firmware/OC switch XOC Re-BAR VBIOS, when I was still on the older OC switch XOC VBIOS, the GPU fans can be set to 0%.

They all 3 did run at 30% before this bios. But they all 3 could be turned to 0 before this bios locked 2 of them to 33%. Try going back and reading the thread.

Same issue here with 3080 Ultra - Afterburner won't go below 30% fan speed :(
 
 
Above this is a comment from the very first page of this thread.. not very hard to find the issues if you take the time to look.

Thanks for explaining.  That's a glitch with the pre-rebar XOC "oc" switch bios then, you're not supposed to be able to turn it to zero.  It's a feature not a defect, lol.

Yes your supposed to be able to turn all 3 fans to 0.. prior to this bios we could.. with this bios it isn't possible.  The glitch is here with this bios. If flash the old bios all works fine.

Well that's news to me, if so there's no difference in the bioses.  The OC switch position bios is supposed to have some non-zero minimum fans, that's how it is on my 3080 FTW3 hybrid (44/44 irrc) and was on the 2080 Ti FTW3's.  If you want all zero fans just run the normal switch position bios, and save the OC position for the non-rebar 450w bios.

I need more details about exactly what isn't working for each of you, and what you expect the fans to do (or do differently) via PX1. 
 
There are changes to the way the fans work, which are more in-line with how the SW team originally planned to make the fans work, so it will seem different than previous versions.  I think there are some UX/UI elements that are not as clear as they need to be (but are accurate based on how the fans are actually controlled), and we are working on that.

Then I suggest you go read pages 19 and 20 .. it was pointed out to Jacob again it was not fixed and we were told it was being looked into. We have not heard from Jacob since.

Thanks, you're probably not going to hear back because the fans on the OC switch bios are working as intended.

Looking into, also can you try the normal BIOS with 450W update, the OC BIOS has a more aggressive fan curve without 0DB fan mode.

That means that some fans run, no matter what.  It's not a bug, it's a feature!
