Flashing ftw3 ultra LHR with the XOC bios (EVGA GeForce RTX 3080 FTW3 Ultra LHR (10G-P5-3897-KL) [XOC/ReBAR]) didn't increase power draw, as tested in furmark. It did let me slide power to 118% but the power draw didn't change compared to the original OC vbios. I have flashed the vbios back and forth to confirm. Anyone else has this issue?

After installing the XOC BIOS on my 3080, I saw the max power draw go from 400 to 420 as the highest. Better than stock, but not the 450~ I was expecting to see like my 3080 Ti. Although, it’s already been determined that the sensors for the 3080 Ti are either inaccurate or not being read correctly by software like GPU-Z. Could be the same thing with the 3080. However, I’d expect to see at least some increase using the XOC BIOS.

thank you very much
very detailed 

anyone have a stock bios for EVGA 3080TI XC3 Gaming 
12G-P5-3953-KR? I want to reflash to make sure my card is ok. It's acting strange and nothing is modified

Hello, just checking in since it's been a while - looking at the thread it appears we still don't have a working 3090 FTW3 Ultra HYBRID XOC BIOS with proper fan control yet,  is that correct?  Looking at Post 1 it's the same BIOS since April which doesn't allow any fan control like the Air cooled versions of the card.

Yup, same thing. I was able to move the slider but it didn't draw more power, and I can't oc it for ****. I RMA'ed it for the time being to fix the thermals on it. Super disappointed with this EVGA card so far. Can't OC and thermals were horrible. Hopefully the RMA fixes things or I'm going to go find a Strix / TUF. 

Can I just trust Precision X ReBar tool to choose the right BIOS for my cards, or do I have to digest all of this and do it myself?

Reason why I ask is I just get an immediate black screen when starting the flash process using the tool - after waiting 5-10 minutes this way I give up and reboot my computer, and then have to recover the video devices by re-enabling them in Device Manager followed by rebooting. Am I not waiting long enough?

Note that I have two 3090 FTW Ultras with the Hydro kit installed. One had the red lips (old model) and one had the black lips (newer model).

Precision has no way of knowing you installed the hybrid kit without you installing the hybrid bios first, so no it can’t just give you the updated hybrid bios.

Changed my 3080 FTW3U to 3080 Ti FTW3U.
Cannot achieve 450 W even in kombustor. All the monitoring programms reports not more than 430 W.
Maybe you'd discussed any solution?
3080 previously maxed out 460W easily.
thanks!

I was told in a separate thread that the hybrid vBios is only needed for LED control and so it’s not necessary?

Should Precision be able to successfully update the existing non-hydro bios though? Why the black screens?

Not sure about the hybrid vBIOS, but that’s something I’m curious about myself since I modded a 3080 Ti with a water block. Anyway, Precision does update the vBIOS if one is available for your card. Just need to look in the Re-BAR menu and you’ll see “update” next to the BIOS version if, again, there’s an update. Otherwise, take a look on the main page of this thread for XOC BIOS for your specific card.
