This, I accepted the situation too. It sucks that my card is so limited that I have to overclock at .816 due the my card's limits but at least it's somewhat matching a 3080ti FE by doing that. Still debating if I should do a step up or not but would just like an real reason from EVGA on why the cards are falling into different piles of power draws.

Would you mind giving some details on the settings that worked for you? Did you undervolted to 816mV (that seems really low)? At what clock speed? Any other adjustments you made that worked? Just trying to get a starting point for when I fiddle with mine.
I was already planning to undervolt this card before I read this thread. I am hopeful based on previous undervolting experience that I can shave at least 50-75W off the power draw to make a 300W limit acceptable. I just got the queue pop today and ordered despite the issues. Obviously in a normal market it would be a pass.

Beware that doing this isn't an end all fix. It can seriously limit performance in workloads that have a different power vs voltage scaling. 
In other words, his settings may not be helpful. 
And synthetic testing is dramatically different than games.
 I can go +265 core clock in synthetic benchmarks and get about 1,850 mhz stably. 
 
When playing some games, this +265 is unstable as the power load is lower and the card boosts well into the 2k range and crashes.
But with a +120 in those games it will still boost to just over 2k and be stable. If I had just set an undervolt that took whatever synthetic benchmark I was tuning against off the power limit, I would have given up the top end of the frequency range.
 
Sadly if you want to undervolt, Ie limit the max voltage and specify a core clock, it needs to be application specific or you can give up much performance. 
 
 

This kinda correct, If your XC3 is powerlimited you have to find the "Floor" voltage where the card drops to. For the Witcher 3 with maxed out settings at 1440p and 180hz monitor, The memory controller is at 30~40% so that locks my card down to .812. I was able to get up to 1815mhz at that voltage and it has been stable so far. By doing that, it gave me higher Avg and stable FPS due to the card no longer ramping to power limit and back down. Different Application will hit the memory controller less or more so the best way to get the most bang for your buck is to set up different undervolts depending on how much voltage is being allowed for the GPU core. 
 
EDIT: Also Thanks to the undervolt too, it actually gave me a 10% boost to my timespy score also, so not really giving up much performace if my card could never get to 1,850 mhz stable like @sentient12's card did stocked

Thanks for the reply. I have a 3070 currently that stock boosts to 1890MHz. For undervolt, I have 1905MHz at 925mV stable. The power went from 230W to around 175W doing that. So, my performance went up (very slightly) while dropping about 55W power draw and 7C in temps. It seems like most people have been successful in undervolting 30 series cards in general, so if I can get even a moderate undervolt, seems like I can be under (or closer to) whatever power limit this 3080ti XC3 has.

Yeah, the Voltage "Floor" for XC3 3080ti if it's power limited like mine is tied to the memory controller load. I assume it scales with it all the way up to 100% but so far non of my games push past 40% (AKA the witcher).

Ended up passing on this due to this conversation & the parallel discussion in the old tracking thread. Thanks Kram, Crum, and everyone else.
 
Time to pound sand while I wait for the FTW3 queue to get to 8am.
 
Should be any second now™  ಥ ͜ ಥ
 
 

This is just a theory, but I think that's because you eliminated the fans and RGB power usage, but whatever limit is being hit does not change.

I saw this behavior, only to a lesser degree when I installed the hybrid cooler on my FTW3. I put the rad fans on the mobo and didn't connect the RGB. But in that case it's still running the pump and single hybrid fan. But it did appear my max power dropped slightly, maybe 5-10w.

Just threw an EK waterblock on my XC3 and now it maxes out around 250w instead of 280w LOL. What is going on...
 
The strange thing is in X1, it reports the card as using 100% power. Not sure what the "stock" 100% power draw of these cards should be, but if its 330-350w, then the card is only really using 71-75% power even though X1 is reporting 100%. Before I put the block on it, it was using 280w and X1 reported the same 100% power usage. This sounds like something that can be fixed with a bios update, looks like its misinterpreting the power from one of the sensors.
 
Though I'm really confused on why the max power draw would get LOWER after putting the block on it? 

what load is this based on? mining? games? benchmarks?

Folding and mining as the card is in the third pcie slot, is there an easy way to make the system use this card for games/benchmarks without having to take apart the loop to put the card in the first slot?

Same here. I was shocked that my $1,500 XC3 Hydro Copper card running at 39°C was getting beat by the $1,200 XC3 air cooled card that can't match the performance of the 3080 Ti FE cards.
 
These cards are trash, the worst of the worst 3080 Ti cards anyone can buy. EVGA should be sued for selling these faulty cards.

Yep. And I find it hard to believe this can't be simply fixed with a bios update. Not that I expect EVGA to help us by issuing a correct bios nor am I surprised they are ignoring us.
 
Would be really helpful for some of the big tech tubers to bring this issue to light so they can't just ignore it.

I am one minute away for the XC3 air cooling card, and 10 minutes for the FTW3. What do you recommend me to do? Should I buy the XC3, or wait 1/2 months for the other one?
 
Is the XC3 performance so different than the FTW3? Still no solution to the power cap issue?

I ordered the XC3 gaming for $1200, after almost skipping from reading this thread. I don't think the card is anywhere near as bad as it is being made out to be. In normal market times, almost no one would buy a 3080ti over a 3080 anyway, so we are already getting a bum deal there. The card I ordered is the 'budget' tier of EVGA's line, so I don't really mind if performance is a few % off 3080ti FE. If I could have my pick of cards at MSRP, I'd get a 3080 FE for $700, but that isn't very likely. For my situation (small form factor case and only using for gaming), I actually greatly prefer the smaller size and 100-150W less power draw than the FTW3 card. Saving $200 and generating less heat is worth a few % loss for me. And if for whatever reason the card is really bad, I can easily get my $ back out of it by selling.

That is exactly how I felt, in normal times I would not even be looking at 3080TI, I really wanted a 3080 for $700, but was in the queue since early dec 2020 for a 3080 and in the end I am happy I got the 3080TI XC3, didn't pay scalping prices and can enjoy my games on my new build with all settings maxed out is the bottom line.

The XC3 is going to be 1-3% slower than a FE and 3-5% slower than a FTW3. So it basically depends on whether you feel the extra 5% performance is worth spending $200 over? You can naturally bridge that gap by overclocking the XC3 as much as possible but naturally the FTW3 can be overclocked as well and has a higher power limit.

Eh, you can overclock the FTW3 too and way more then the XC3. My FTW3 stock destroys the my XC3 cards overclocked. My XC3 cards overclocked can't even beat a stock FE. Both my XC3 cards are pathetic and not worth what I paid for them.

Of course but the ftw3 is often being held back as well it seems. From what I've seen so far, and this is just from what I've seen, that card a lot of times stays around the 400-420w limit as well. So that too is handicapped when compared to other 3 pin cards around the same price.


Just to add to this, what's happening with a previous user is concerned though, where changing the water block on the card somehow is reducing performance.

I have a 3080 Ti FTW3 and I can easily hit 450 watts.. not sure about other cards but the 3080 Ti variant is working as advertised

No surprise to me, my XC3 Hydro Copper performs worse then my Hybrid cooled card.
 
EVGA should either refund people some money that bought these or a free Step-Up to the FTW3 card.

That would mean they'd have to refund all the other skus with power issues which is why I don't think they'll publicly announce anything. Might just do an internal revision and change out cards during RMAs

No issues with the one I just installed. I see it hitting near 350w.

So I'm lost. Is there or is there not an issue with all 3080 ti xc3? I read on toms hardware something different.

Not for me at least...I'm upgrading from a 3080 xc3 ultra gaming. timespy was around 16800-17800 looking at prior results depending on how much of an OC I had with that. I'm sure i'll be able to boost that 19287 score with some tweaking too...beyond this being a hybrid too

It depends on your card, it seems they are falling into three lots. 304 watts, 330 watts and 350 watts.
