I'm not able to get anywhere near the benchmark on Port Roayl with the XC3 ultra.
I see you are getting about 14K score in PR mine is about 11K, having said this I can only move the power slider to about 111% on the KFA2 390W BIOS.
And my sweet spot for a manual OC is about 130/500 with custom fan curve, anything more than that has diminishing returns.
Thats like a 3080 score, If your getting that on a 3090 theres something really wrong with your computer.
Thanks yeah I was actually running a custom test, which for some reason does not run the same. I also realized that I am CPU bound, got myself running a R7 3700x and @ 1440p. I just picked up a R7 5800x so that should alleviate that. bmgjet

Maybe I'm not reading the charts right....
I am a little confused here regarding what can/cannot be accomplished with absolutely no soldering or shunt modifications on the 3090 XC3 Ultra (no mod, liquid metal or physical alterations of any kind on the PCIE resistors or the resistors controlling the pin connectors).
With only a BIOS flash.... which BIOS is the highest performing? What performance does that translate to in the chart above?
P.S. If I get this card I will likely water cool it (FTW3 cards are not only hard to find, the waterblocks are all sold out), so temps are not a concern....
390W is the most you should run on a completely un-modded card. And even then you will want to turn the fan up a bit higher.
696W is the most youd get using the 1000W bios but you need water cooling to use that.
I plan on a full custom loop in the next week or so, can you point me to the right bios and mod to turn the XC3 into a 696W card? Note I have a soldering iron and I am not afraid to use it

Don't I need to mod to allow that kind of power?
Its 1000W over 3 plugs. XC3 only has 2 plugs so it ends up at 696W. But really you should dial it back to under 550W to keep the fuses on the XC3 from blowing. famich
Sorry, if already explained. https://mega.nz/file/OLhRGYwY#ri9rYOW3YIShirEL6vo2PLpkO7KiXybdLA7ul6nGJrM
Safe to use it on hybrid card? Or do I need another BIOS? I am going to save my original BIOS using GPUZ or NVFlash, of course.
Should be fine. Just youll need to use the patched libarary.dll that I mentioned in the first post to get PX1 to work for RGB control.

If I read you correctly : the ready made update contains Gigabyte 390W BIOS that is however meant for the air cooled card. But Gigabyte has got the custom PCB just like Hybrid , so far so good.
Secondly , after the update I am going to lose LED tweakability by PX1.
SO the LEDS go out , most probably . For me no big deal . BTW I do not use PX1 for OC/monitoring, I am using MSI AFB.
Apart from that , according to this and oither forums the last PX firmware update is simply no fully OK. I am not plannign to apply it.
So, if I try that GB BIOS I am going to gain 390W power target and no LED "music", right ? From what I have read ? E VGA is not going to release any new BIOS for these cards, that is for sure. Correct me if I am wrong. Thanks for your help and effort.

Ready made one contains Galexy 390W. VRM, DPS and Fans have same layout so work good.
Hybrid is same PCB as air cooled they changed nothing but put a AIO cooler on it.
LEDs stay on what ever was last set. Patching the dll file lets you control them again.
EVGA refuses to release a offical bios that will make the low tier cards risk up setting people that paid extra for the FTW3.

Ok, pretty much what I have thought. I have already prepared the originakl BIOS and embeddded it to "update.exe", so I got 2 "exes" now. BTW thanks, will give it a try. My card goes well, but , as already numerously agreed upon, lacks the PWTGT.
I will not update the FW for PX1, so f... them. Galaxy BIOS was udes by me duriny 1080Ti and 2080/Ti/ time,s I believe. Good cards.
Thanks once more. will let you know.

Is there a similar BIOS that I could use to raise the power limit on my 3080 XC3 Hybrid? I'm currently seeing temps in the low 40's, so I'm sure it could hit higher clocks with more juice.

3080 xc3 - no bios is going to gain you anything. Download NVflash and the higher limit bios' off of the verified list on Techpowerup and try yourself... but multiple folks have tried pretty much all of them, and they all do nothing different. *edit* if you bought the hybrid kit to add to your xc3, then flashed the file linked in the EVGA forums, there is an issue with it some folks have had where it is causing lower than normal boost behavior. Going back to the non-hybrid bios (or getting a stock hybrid cards bios) seems to clear that up.

No bios is going to fix the 3080 xc3 it has a hardware design issue. (Basically the 3090 XC3 VRM layout but the removed power phases that pull power from the plugs)
Best thing you can do is use a bios with a higher slot power limit but thats only going to give you 10W more before its on the slot limiter again and way under the boards total power limit.

@bmgjet My apologies, I have just seen that most of the questions that I had asked you for a couple of times, had been answered by you in the 1 st post. I have overlooked that. Sorry -)
Apart from that, nice work. Are you active on Overclock.net ? I got an account there, too.

Well, that patched update from EVGA worrks well, was able do flash the KFA BIOS and after that the original BIOS from EVGA Hybrid back with 0 problems. KFA BIOS? however, did not produce any much better results for me: maybe it is because my card is able to boost
in WD Legion up to 2115 @130MHz offset and 800 Mem, so.. not bad. Port Royal score with EVGA BIOS was actually a bit better 13400+ points / AMD RYZEN [link=mailto:5950x@4570]5950x@4570[/link] memory 32GB DDR 4 3866 MHz/.

Alternativly here is a 390W update.exe already modded.
https://mega.nz/file/OLhR...LpkO7KiXybdLA7ul6nGJrM
I wont provide the 1KW XOC already modded since that is really a risk to your card if your not careful.
Finally got a nice OC on the KFA2 390 BIOS, pushing 130/500 stable across all test, Port Royal Score 14000+ Anything above this has diminishing returns. Thanks Question, where can I get the updated KFA2390 BIOS with rebar support? https://www.techpowerup.com/vgabios/226727/226727Is this the space I should be watching for an updated version?

I topped out at 14783 on PR with the 1kW bios (at 70%, same 175/1000 settings too) on my XC3 with an EK block. I REALLY wanted 15000. The temptation to just nudge it a few percent more nearly got me, but a benchmark score isn't worth it.
But that KFA 390w bios did easily best my top GBOC score of 14276 at just a bit over 14300 without trying too hard with undervolting and whatnot.
I have noticed something odd. Occasionally when I start up a PR run it'll just be slow. Like starting at 57-58 FPS rather than 66 (on a good 14700ish run). So I stop it, reinstall Nvidia driver, and it'll rip off a 14700 again. It did this with my old GB OC bios too. I didn't have the stock bios on it long enough to notice if it exhibited the same behavior.

696W is the most youd get using the 1000W bios but you need water cooling to use that.
696W on a 3090 XC3 Ultra with only 2xPCIE connectors? Where is that power coming from exactly? So I'm assuming 696W is just what is reported in software and actual power draw is really like only two thirds of that due to the firmware being built for a 3 connector card. So real max power draw somewhere closer to 464w? even that would need 175w on each connector and 114w on the pcie. Bold move. But one thing is for sure, I'd need to throughly understand that math behind this before attempting to install that 1KW bios on my XC3.

When it reports 1000W your only getting a real 696W because the phantom 3rd plug that gets reported by bios (It just copys the reading of plug 1).
So you need to go into HWINFO and adjust the offsets to make it read correctly. Which is to remove about 33%.
You dont want to go over 520W tho on a XC3 because the fuses will blow. But the guys with cards without fuses like Tuff there cards are hitting 98W from the slot and 300W from plugs.
Mine im happy enough with 500-520W which has it pulling 210-215W from plugs and 90W from slot.

Sounds like their cards are built Ford Tuff. Couldn't we just shunt a blown fuse and be done with it? That way we have a card built Ford Tuff as well?

If your going to hardware mod then you might as well just shunt mod it instead since you no longer have a warranty. Then youll be able to upgrade to the resizable bar bioses when they come out.
If your going to hardware mod you might as well do some supporting mods to make higher draw safe. Like remove the fuse for the slot power draw and run a wire from that to a external molex plug so you can pull more then 100W safely from that input and bridge together the 2 plugs 12v planes so so they are always balanced.
And depending on your soldering skills remove the vrefin resistor on the vrm controller and replace it with a pot so you can turn voltage up over 1.1V.

Use the tool I linked in the instructions.
Open the update.exe you want to use as the base.
Click patch and select the orignal bios for your card and it will put that bios into it.
so I tried the modified 390W Bios update you linked in the first page and seem to have gotten a little bit better however it wont even run 3dmark, when I ran 3dmark it reboots the computer. When I was using my RTX 3070, I frequently get around 200fps+ on low on the lobby menu screen as well as in game.. but with the XC3 3090, I barely get 200fps on the menu although sometimes I get to spike to 230-240fps often in-game. I also noticed it still even barely pulls out 300W while running warzone and kept getting Performance Limit - Reliability Voltage if not I get Utillization all the while GPU load is just averaging around 70-75% max settings. So I tried to reflash it back to the original bios using the Romupacker and loaded update.exe from EVGA FTW and patched it with the original ROM that I earlier created using GPU-Z and saved it as XC3update.exe. Ran the XC3update.exe and got this message that no display adapters were found that are compatible with this update.  Do I need to use an update.exe from an XC3 update to restore it back to original BIOS? Do I have a defective PSU?

I have no issues doing all that if it allows me to crank this card up to 11, lol. I would be interested in all these mods. Do you have a link to the read up on that somewhere, is this what you did to yours? Also a parts list would be helpful, digi-key is where I would be able to pick them up I assume.

Patch the 390W one with your orignal bios. But to me it sounds like your computers PSU isnt handing the load and switching its self off. GlaucomaPredator

More power and voltage isnt going to really help my card so 500-520W is enough for it so no need to mod my card further then bios. 1V it does 2100mhz and 1.1V only gets it to 2175mhz so not the best clocker and not worth hardware modding since it would probably only allow it to get to 2200mhz which I could probably get by just selling my card and buying a new one until I find one with a better quality chip. But the hardware mods are the same as what was done back in 1080ti days since it also used the same vrm controller (up9511r). So you could probably follow a guide from that.

do'h I feel stooopid right now lol.. I was so focused on the update.exe and didn't realize that the 390w was a modified update.exe.. It's working now! as for the PSU, I will try an external PSU.. I got a spare one with the same model and use it just for the card. Appreciate the response!

I just ordered a 3090 XC3 and Hybrid kit.
This still working fine for that combo, just a matter of running the 3090XC3.390W.exe letting it update the card.
I figured 390w is fine for everyday use, not casing 3D mark scores, got rid of a Inn3D RTX 3090, that thing cooked, never drew over 345w, too loud, at least with the Hybrid kit on the XC3 I can keep it cooler, get better performance.

I just flashed this to my card, flashed without an issue, but hwinfo still shows 365w as max power. Is that just hwinfo showing incorrect info or is my issue something else?
