So, this BIOS was posted on Oct 21, which is about 1 1/2 months ago, and we haven't heard anything from EVGA about the problem of if it's going to be fixed anytime soon. This lack of communication doesn't bode well with me... :/

Open case, cold ambient temps.
I figure if i can't get this card to run at 500w in these unrealistic conditions on air then it wouldn't do it for anybody running it in a closed case. 

I've rarely seen my card over 60c under load.  I've rarely had my ambient temps more than 22c.  The rest of my test bench is water cooled so very little latent heat from other components.  I have directed two 140mm noctua industrials at the front and back to ensure no pockets of hot air exist.  Nothing changes the 450w max power usage on the xoc bios.  I can get my card to hit 72c if I add 20mv, underclock the gpu to -64 with zero mem OC.  The resulting scores are abhorrent.  If I OC to 1448 mem and 240 gpu temps stay around 52-60c and I get much more normal (but still low for a 3090) scores. I still think some nerd hand tuned the tables in these things and didn't know what they were doing.

from the src physical perspective, it shows continuity to the shunt at the very top and the shunt at the top left (within the 4 group) not sure the reasoning... (i can't recall if it also shared with the pcie shunt or not, but the pcie rail and the src didn't complete, so not sure...
as well, power pin 3 shares the 2 shunts on the right side of the group of 4 along with the src, as well other pairings for the resistors for power pins 1 and 2
 
doesn't really change much for us at this point, but later on, when inclined, maybe i'll try mixing up resistances across all shunts and see what happens... any guesses? probably 2d clock lol
 

Are you referring to this picture?
https://www.overclock.net/attachments/shuntmap-evga-xc3-jpg.2462012/
 
Yes that makes sense.  My SRC goes down when I mod the two 8 pins on my 3090 FE well, and is higher if they are modded poorly.  If you mod it really poorly, like terrible on 8 pin #1, good on 8 pin #2, so 8 pin #1 goes to 177W while 8 pin #2 is only at 135W (triggering PWR from 8 pin #1), SRC can be above 130W....(GPU_Z readings).
 
My last Heaven 545W run had SRC at 91.4W, 8 pin #1 at 155.3W, 8 pin #2 at 137W.  Board Power at 345W, Chip power at 169.9W, PCIE Slot at 53.9W, TDP% at 99%, TDP Normalized at 104.2%.
Those are GPU-Z values.  The multiplier for Gpu-Z to hwinfo/converted board power draw is 1.6x *

So my max power cap should be around 600W or so.
 
I have an old picture from pre-mod when I did a superposition run at 114% TDP, and board power at 400W (max), and SRC was at 103.9W
So that does make sense.  The other rails: Total board power: 400.68W, 8 pin#1: 175.5W, 8 pin #2:170.8W, Slot: 69.73W, Core Chip Power: 226.6W, FBVDD (MVDDC):46.5W.

I know the absolute cap is 79.9W for PCIE Slot and 300W for Chip Power.

Not refering to any picture, just what i found on my ftw3 and multimeter. Using smd solder paste so no concerns with that...

As for multipliers, it doesnt work out for me, as the kilawat numbers shown dont add up. One session of measuring..... Pulling 970-1030w on kk, corrected hwinfo and gpuz values ~ 950-990w, (live) where system and cpu draw would be a minimum of 225w-290w.... /Shrug i dunno

Just did a run then +1000 mem +195 core for 5 mins on Kombustor Physx4 GPU - Hard, no worries maintaining that clock.
 

Thanks for the additional info. I'm going to pass this info over to our Product Management team and have them look into it further. If you could, please shoot me an email directly at ######### and when I have more info for you, I'll let you know directly.

 
This was the email i got back after a not so enjoyable back and forth with customer service.
I mentioned the issues with the cards in general and asked them to please take a look at this forum as everything they need to know is here, hopefully we get some answers soon.

Agree BUT!
Forum moderators are(should be) responsible for re-directing our feedback to other divisions within EVGA (RnD, engineering team for potencial fixes, future improvements) and give us atleast short rundown whats going on, I know u dont have much technical information about the case however basic PR response such as "We gave all your feedback to engineers and they are working on potencial fix within days/weeks/months and will continue to watch/investigate this issue with this community" should have been posted here weeks ago. I noticed moderators watch this thread but still failed to manage it properly, because of your lack of response/reassurance that something is happening in order to fix this mess lot of people have built up rage against evga, nonsense youtubers started to make videos as "boycott evga" and cards are getting/trying to get RMAed so we dont have to wait for fix which we even dont know will exist.
U have quite few skilled people here, why not ask us for detailed relevant data of our cards with our testing results so u can send it to engineering team for faster potencial fix ? We already gave u idea whats going, so please act.
Im not even gonna comment that youtubers (Jayz2cents etc..) are getting 1000w XOC bioses and me as a XOCer have no way to get one :)

Why is the 3090 FTW3 Ultra, with 500W BIOS on OC switch,
a) drawing so much power from the pci-e SLOT
b) not drawing near full 500w (119%) power?
 
This is on an AX1600i (1600w) PSU with three separate 8-pin power cables.

On the AX1600i,
>the +12V rail is split into twelve separate +12V rails, each with a default OCP of 40A
 
So I'm not sure the post you linked is applicable in my case, unless I'm misunderstanding something?
 
Thanks!

"It's not just PCIE slot vs PCIE 8 pin. And it isn't slot vs only 8 pin.
It's any power rail that has its own power limit vs the PCIE 8 pin *AND* PCIE slot added. Remember TDP% is all the PCIE 8 pins and PCIE slot added together.

It can even be an 8 pin#1 reaching 150W while the 2nd 8 pin is 105W and PCIE Slot is only 50W. The 8 pin #1 reaches the "8 pin" power limit, triggering throttling, when your board is only at 305W (let's assume your board TDP here is 400W, for example)."

The only way I can understand that being relevant to me, is if the pcie slot power is hitting limit and thus the card hitting power limit - despite the 8-pins not being anywhere near power limit. IF thats the case, then what decides to use pcie power instead of 8pin and how do I fix it? If thats not it, then I'm still not sure how that post applies to me... Sorry for being thick. My PSU has each 8pin cable is on its own 12v rail and each rail is rated at 40amp/480w.
 
 
FWIW the 3080 FTW3 Ultra w/ XOC bios hit 440w no problem

arestavo
As I read it, that is the case. And apparently why our cards power throttle so much (mine can show power as the limit even at 400W on the 500W XOC VBIOS, or 520W Kingpin one).

 
So there's something wrong with the 3090 FTW3 Ultra (XOC) BIOS that makes it draw too much power from slot is what I'm hearing.

What decides is probably the vBios itself.  I highly doubt power balancing is hardwired.  But modding the PCIE Slot shunt fixes the early throttle for everyone.
However please read Drunknfoo's post last page.
 
He implied that the PCIE shunt has continuity with MVDDC (Actually I found this out myself, by seeing people who weren't modding PCIE on their Founder's Edition cards, but modding all other shunts, having their MVDDC Report sky high like 238W, then when the only change they did was modding PCIE Slot after, MVDDC dropped to about 120W), and he tested himself that "SRC" shunt has continuity with 8 pin #1 and 8 pin #2, and 8 pin #3 has continuity with both "GPU Chip Power" and "SRC".
 
The rest is up for people with multimeters and soldering irons to test.
 
There are also two "mini" 005 shunts on FE cards, linked to GPU Chip Power and PCIE Slot.  No idea what they do--they do NOT affect main TDP--they might affect the "strange" random throttling at high loads...

Steven from Gamers Nexus used 5mohm and 8ohm on the 5 resistors and shorted the fuses but he never revealed the real mod he just said that when he first did it he had to troubleshoot the card for like 6 hours maybe he blew the fuses or something else happened. So I'm not sure if I want to do this to gain just 100Mhz+ that will be only for benching, he himself said like Der8auer that those clocks couldn't hold gaming and these guys use light games not like Metro Exodus I've tested for weeks now using XC3 BIOS on Stock Air.

My friend has those 204% TDP BIOS and he told me is garbage, he also told me that if I want to go high on clocks for benching I need to mod/voltmod the card on water at least and use the ASUS BIOS, and he is a very well know Overclocker, he has 4x 3090 FTW3 Ultra Gaming that he binned. But, he doesn't reveal the voltmods exactly not even to me :/
 
Cheers, Sergio!

I have the screens of all my tests and i offered on other posts for whoever wants them (XOC and XC3), mem does help in FPS for sure. 

 
I'll double down on this.  I have 6+ pages of 3Dmark alone showing the performance scaling with no GPU oc and with GPU oc and on stock ftw3 ultra OC bios and XOC bios.  1448 mem is great.

Y'all are probably waaaay overdoing your memory at +1000 to start with. The ECC will keep it stable but it's probably not helping performance.

Yup I've tested with an actual game as well.  Jumping up from +250 on mem to +1000 on mem netted me over 5% fps gain in Horizon Zero Dawn maxed out at 4K.
 
 
 
Anyway...those with the FTW3 Hybrid cards, have you had any luck with this bios?  I just got mine and had time for 5 minutes of benching before heading to work.  With the KingPin 520W bios, I was power limited to around 430W~.  Will do more testing when I'm home in a few hours but wondering if others are seeing the same thing and if there are any options to increase the power limit outside of using the Strix 480W bios or shunt modding.
