I thought that might be the case.

Hi guys, been gone for a bit. Slapped a hybrid kit on the 3090. I guess the consensus is to use the XC3 hybrid bios on this thing, however, once flashed I can’t open precision or it will try to install incorrect firmware. So the solution is to use AB. I can do all of this, not too difficult...but how the heck am I supposed to control those fans with AB. When it was on air I tried this, linked fans and it was almost impossible to control them properly. Will I have to buy a separate fan controller? My experience was that 50% of the fans in AB resulted in only 25% fan usage (rpms).

You need a corsair commander.

I see how I could connect/control the two fans attached to the radiator with the commander pro but as the cords coming off the shroud are male I don’t know how to connect them to the commander or control the shroud fan with the commander. Still trying to figure this out sorry.

Can you not set the fan speed to a fixed % and have it work without a fan controller? I had no issue doing so with my 3090 with the XC3 VBIOS air cooled or with a hybrid kit.

I do, however, use the NZXT RGB & Fan controller and the software NZXT CAM to control the rad fans.

With Corsair's controller, you'd have to use their program called iCue. https://www.corsair.com/us/en/icue I find it to be utter garbage since it messes up the forward and back keys on my corsair mouse (they fix it then break it, and I'm done with it).

I could use a fixed percentage maybe. In afterburner the percentages are always off by a lot (lower rpms than I set for a curve) I don’t know if that would be true for fixed percentages. I really want a curve not a fixed percentage though. It’s not so much xc3 bios giving me trouble but accurately trying to set a fan curve in AB, and being locked to AB (can’t even open precision or firmware w/incorrect MCU loads) with XC3 bios. I feel like if I connect both rad fans to the fan controller (whichever kind really software is all bloats, I use icue already for my h150i pro) I can control those fans w/software but the shroud is still being controlled by AB (in this scenario).

Try Aorus Engine, it can identify fan RPM correctly.

So the only solution is to use real rpm measurements and determine to the delta between afterburner % and actual % rpm and account for it in afterburner? (Determine what % value in afterburner produces % actual desired rpm) sorry if that’s confusing

Aorus Engine is another option for overclock, and it can replace AB. It is provided by Gigabyte.

Hi,
I have updated to new BETA in both positions OC and Normal. Now when I am changing the position from Normal to OC the XP1 showing the same bios for both position ( Normal) and Fans profile remain unchanged ( stopped fans). 
Meantime the GPU-Z showing the correct Bios version when I am changing from OC to Normal and Vice Versa , but the profile remains unchanged in both positions ( Fan remains idle even to OC position).
I tried to install the Normal Bios again with no any changes . Only one Bios showing to XP1 in both position.
 
Anyone else with same problem? Or is a problem with switch?

Had the same with the normal oc and stock bios. 2 ways for solving. Switch on running card then reboot and it shows the correct bios you have switched to, after the reboot.
Second way shut down then switch then reboot- now it shows the bios before switching (the wrong one) - only reboot again and everything works as it should. I dont know why but it works for sure.

Solution 1 for my understanding should not be the way to go, but i am not an expert.

You are right . I had to make two times restart to load and show the correct Bios. Thank you very much for your assistance .

What percentage do you keep your shroud fan running to manage temps? I am attempting to set this part up today, and do you just use afterburner for that fixed %?

The fan shroud I keep at 75% all the time using AB, as that fan can get quite loud. Louder than two ML120 fans at 100%, which is crazy. Temps for memory and VRMs are all mid 70s at most from what little testing I did.

I now have everything plugged up and fans running through a controller, one question: is this the regular xc3 bios that you’re flashing and using w/a hybrid and fan controllers or did you get a hold of the xc3 hybrid rom, I can’t find a rom for anything but regular xc3

seriously EVGA..... You still have not fixed this months later? Its a fricken bios. It should not take months and months to make. #bringbackEVGAfrom2015

Just measure the PCIE slot power draw without an overclock, via GPU-Z, on the stock VBIOSs. If you're over 75W, RMA it for being out of spec.

How much over would be allow-able in your opinion? I see mine getting close to 77watts running 3DMark (board pulling around 460watts max with the OC bios). Thanks in advance. 

The PCIE spec is up to 75W. If it is over that without an overclock on the stock VBIOS, then it's out of spec.

Whether or not you accept that is up to you. I accepted 76W continuous over the old card's 82W, but that's just me.

Yours sounds fine.  If it were 395w board draw on the OC bios and pulling 77w while hitting power limit I'd be worried.

So i have still found that the xc3 bios are still the best for over clocking, but has anyone else tested using aurous OC engine over afterburner to get more accurate fan control with xc3 bios?

I found an annoying but accurate way to control fans with AB, if you set the fan percent on the main screen, it’ll jump to what it’s actually using and show you. So I wanted 80 I had to run 86% if I want 70% plug in 79% to AB, 55% actual is 69% in AB 50% is 65. It’ll run it correctly it’s just off. Since 100% does reach 100% rpm speed, any number you want is attainable.

thanks for the reply! that does make sense, i did notice the fan number dropping after setting. I would prefer to run my fans at 100% all the time but i could settle at 95%. The only other issue i noticed though, is when playing gta V, I had my overlay on to monitor my fan rpm, and it would go from 3000 rpm to 2500, to 2700, 2800, than spike to 6000, than back to 3000 and repeating. I verified with my eye balls that all fans are actually running, but couldnt tell with the weird rpm charts if my fan speeds are actually going up and down than spiking. But it could be a bit concerning when it spikes the rpm like that on the overlay if it is actually spiking power the fans in real time as this may cause excessive wear if this is the case but i couldnt verify. if the aurous engine seems to make the fans stable, I could just switch to that and port over my same OC from AB. But i guess if no one else ends up having input on this, I may just have to try to test my self XD

When trying to restore the original BIOS I'm getting this error "No display adapters were found that are compatible with this update."
 
I'm on an EVGA hybrid ftw3 ultra hybrid. I flashed to the new OC BIOS linked here. however, I want to restore the stock bios due to hard crashes while playing Warzone. 
 
What do you recommend?

2021 and no update no news from EVGA on XOC BIOS...

2014 Made in Taiwan Red plastic
 
XOC OC BIOS for this card + PX1 max power limit
 
EVGA GeForce RTX 3090 FTW3 ULTRA
 
491W is the max for me.
 
PCIE power draw is 73-78W
