im already download  and extract 4897_Normal_450W_ovu.exe but i got this error message 
ERROR: Unable to set-up NVFLASH driver (0x00000005)
Detailed :Access is denied.
Please note this error and contact your display adapter manufacturer's
technical support line. It is important that you leave your system ON and NOT
reboot until instructed by your manufacturer on how to proceed.

Access denied? Do you have Fast Boot and CSM disabled in your motherboard BIOS? Also, are you running any anti-virus software? When I flashed my 3080 BIOS to XOC just a short while ago, Windows was like, “Hold up! Are you sure you want to run this .exe?!” I said yes, but then my anti-virus software was like, “Hold up! This .exe looks dangerous!” I dismissed that warning also, and the update then proceeded without issue.

Ok finally got my hands on a 3080 FTW3 ultra.
Ran some benchmarks stock and tested out the aux fan header etc then decided to flash the XOC bios from this thread:
Rebooted and ran some benchmarks but still saw the same basic power usage of around ~380W with spikes up to 390-400w.
At this point the AUX fans were still working properly, crank fans to 100% in afterburner, all fans including the AUX fans went to 100%.
So trying to figure out the reason for the power limit not increasing, I install Precision X1. It updated the firmware and now the aux fans are stuck at ~20% (barely spinning) nor do they show up in X1 as being plugged in.
How can I revert the firmware update and get the XOC bios power limit working?
 
I found this program that can force flash a firmware but I can't make sense of the naming of the firmware files to figure out which one is for my card.

These are the names of the firmware that is in the precision firmware folder, any idea which one would match up with a 3897-kl?


 

  If I could find the right model I could work my way back through the firmware version until I found the one that worked. 

ftw3 hybrid on the new rev 1.0 only pulls 467 watts not the full 500

Is it possible to boot using 1 set of firmware (OC Mode/Switch to OC) but update the firmware on the Normal/Switch to NORMAL, or to specify to update the NORMAL verison of the firmware by software?
I can not boot to my OC firmware after a bad update, but OC (not updated/default rebar) is fine.
But I want to restore my backup firmware.
Installing a 2nd GPU does not work. Video goes to the 2nd GPU as long as the 3080 is set to OC firmware, but as soon as its switched to Normal, black screen only and GPU error from the MB, even outputting to the 2nd GPU.

I thought I saw somebody mention hotswapping to reflash the bios (i.e. while the PC is on with the working bios, hit the switch on the GPU to the non-working and reflash via nvflash), but I haven't personally tried it.  Trying to find that post now.  Also, do you have disabled CSM in the mobo bios?

 
I've heard its possible on NVIDIA, but not if it specifically if it works for EVGA, 3080s, FTW3, not found anything specific.
I do have CSM disabled now. But might have been that or fast boot that caused the issue with my NORMAL bios in the first place.

Question, regarding the XOC that ships with the 3080 Ti FTW3, is it the most recent?

Probably not. Check PX1 in the ReBAR menu. It will show “Update” next to the vBIOS version if there is one.

So i just flashed mine following the steps, everything was good. I went to vbios and there's an update. I should update the vbios with no issues right???

Make sure Fast Boot and CSM is disabled in your motherboard BIOS first.

well it appears that the vbios server seems to lose connection resulting in faux update notifs, as I had already earlier this afternoon actually updated. Now when I switch bios and/or reboot it gives the false update notif, so perhaps another PX1 update is in order?

The update was released with PX1 1.2.3. Try that version or 1.2.4. Otherwise, it wouldn’t be the first time lately that EVGA has had issues with its main site and the forums, so maybe the update server is borked at the moment.

Hello!
I've just picked up another 3090 XC3 Ultra and this one seems to have a newer BIOS ... Is it worth updating my original card?
Original Card BIOS - 94.02.42.80.C1
New card BIOS - 94.02.42.C0.10
 
Thanks!

I didn't write any of these programs people use or engineer the hardware but I think things are working as they expect. (we are all guessing unless we are those people)  I have nothing to back this up but I feel the hardware will decide what it needs based on the what the software is demanding. (or vise versa)  People, go play videogames.  Put a few hundred hours into something you enjoy and use the hardware. Or don't and spend way too much time on forums never getting the answers you need or want. (mostly just a bunch of BS from people who also spend too much time with their confirmation bias) It does not matter how your card/system performs under stress tests or benchmarks if games behave differently so go frag something already. My card has pulled 460W and that was just by playing The Ascent with friends for a few hours.
 

Well said Sir

Anyone have any luck with any other of the bios on the 3080 ti xc3 ultra hybrid? What's the power limit on the bios on that one also?

Do we still not have a working 450w BIOS for the 3080 LHR ftw3? Pretty disappointing this card maxes out at 105% pwr limit. 

There’s 3080 FTW3 LHR BIOS on the first page of this thread. I installed it on mine last week when I got the card, and the power slider now goes to 118%.

I installed my EVGA 3080 Ti XC3 about a month ago and put the hybrid waterblock on it at the same time, and since then, I've flashed it with the BIOS in this thread so Precision X will recognize the card as a hybrid card. Everything has been good since. Now, Precision X shows my running Graphics VBIOS 94.02.71.00.CE and shows an update next to it. I just want to make sure it's safe for me to update the BIOS this way since I flashed the card with a different BIOS than it came with. During a time with cards so scarce, and expensive, last thing I want to do is brick it. Is it okay to update the BIOS through Precision X? Since it should be a newer BIOS for the 3080 Ti XC3 Hybrid, I'm assuming it'll be fine, but I'd like some kind of confirmation first. Thanks!

Would still like to see a higher power limit bios for the 3080 ti ftw3 ultra. 

Heck, I’d appreciate a 500W limit, or Nvidia to not be so anal with their GPU boost feature.
