The vast majority are using three separate cables, and no, it's not something that they are doing wrong. The cards which have this problem, have this problem, and there is no official way to fix it. See page 1 where we just got done discussing this line of thinking.



I still am not understanding why you are a part of this conversation when you don't even have the GPU in question...other than attempting to tarnish a company's reputation.  It's actually pretty ridiculous.

Are you replying to me? If so, don't you see the 51w draw difference? Is that by design? Look at your power draw and post it so I can see yours draws the same. Also reply with something productive please.

Did you read all of the helpful information I wrote on the previous page? I assured the user that it is not just them. I have provided a small amount of evidence about what the issue could be. And via the link, I indicated that if the card is replaced via the warranty process, one with better power balancing could be received. Most importantly, via the link, I have explained why this is an issue, why the user should care, and why they should try to get this issue resolved. If the user has a card with particularly bad power balancing, the two options available appear to be: 1) get the card replaced via warranty and hope that the one received has better power balancing, or 2) use a different card's BIOS which tricks the card into ignoring the power balance issue or makes it forget that all of the power inputs even exist. No other solutions have been found; not daisy-chaining, not not daisy-chaining, not changing power supplies, not changing power supply cables. The cards with particularly bad power balancing have particularly bad power balancing as a characteristic particular to them. When users have gotten their cards replaced, they have seen stark differences in power balancing; this confirms the root cause was within the card itself.
 
Summary of why someone should care: if a particular card has particularly bad power balancing (let's say the PCI-E slot reaches 75 watts while the PCI-E #3 connector also reaches only 75 watts), that is 75 watts "missing" from the PCI-E #3 connector which will never be recovered.  The card will never operate at its full possible potential, because the PCI slot reaching 75 watts will power limit the rest of the card and the card will not ever be allowed (via official means currently available) to consume the missing 75 watts on PCI-E #3.  This can cause a big difference in performance.  Using a different BIOS which is not officially supported by the card can help.  Or replacing the card can help.  Both methods have been proven.

Why are you part of this conversation? What of value have you brought? Does 'hey, you are dumb' help anyone?

I am not trying to tarnish a company's reputation. A company does that -- or doesn't do that -- on it's own. I always try to keep it real, no matter. I have given high praises of EVGA too. Right here, and right now, is just not the time for high praises.

Again,
 
1.  Do you have this GPU?  If the answer is no, then you are just parroting what you have read.
 
2.  Have you done these tests yourself?
 
3.  Are you regurgitating what others have said, and only what you "wish" to repeat?
 
4.  Why do you keep overlooking those who do not have an issue with this GPU?
 
Of course these are all redundant questions.

Turbo-12RAgain,
 
1.  Do you have this GPU?  If the answer is no, then you are just parroting what you have read.

No, I wouldn't buy one.
2.  Have you done these tests yourself?

No, I don't have to.
3.  Are you regurgitating what others have said, and only what you "wish" to repeat?

I am providing the information relevant to the user in this thread.  I "wish" to provide information relevant to this thread.
4.  Why do you keep overlooking those who do not have an issue with this GPU?

Because it is irrelevant to the user in this thread who is experiencing these issues.  When I say that some cards have this problem, I am necessarily acknowledging that some cards do NOT have this problem.  I do not attempt to state how many do versus how many don't.  And I don't bring the topic off-topic by discussing those cards which don't have a problem.  I simply acknowledge that some cards do have this issue, some cards don't have this issue, and then discuss, relevant to the OP, cards which do have this problem.
Of course these are all redundant questions.

Yes, they are.  Please go away.  Have you noticed that the OP has not selected and highlighted any of your response as "Helpful"?

I've seen completely wrong answers get 'helpful votes'. Which giant massive thread of nearly every one having defective PWM operation are you talking about? I can't find it. I do find the usual confusing mix of claims that could be anything from GPU-Z being wrong, to daisy chain inputs, bad PSU to bad PEG cable...etc... is there somewhere where all this mess is put together in such a way as to make any sense?
 
Critiques that you're possibly exaggerating the problem are not without foundation given your tone and volume... considering you do not own said product and apparently won't because... you believe it's inferior? Right? You're entitled to your opine of course... I am not sure why you're arguing you're NOT complaining about EVGA.
 
"You are not alone, that's for sure.  But I am sure it's "fine".  It's a "feature" to have a messed up VRM."

I thought the 3rd plug was just drawing less when I first noticed this, damn. I seem to have 3080 ftw3 ultra with a weak 3rd plug. Hmmm. 
 
But is this really resulting in less performance? I mean I've tested 3dmarks and been scoring as high and above as average, surely it would be then weaker then average?

There are plenty of 2x8 PCIe power cards to skew the 3DMark benchmarks in favor of any 3x8 PCIe power card.  But to answer your question, a power imbalance will cause throttling (Power limit) if any one of the rails supplying power tries to go over its limit.  So if one of the PCIe connectors tries to go beyond 150w and the card is not as the BIOS total limit (eg. 450W XOC BIOS) then it will still cause a Pwr limit state to be set resulting in the GPU trying to reduce GPU boost to limit power consumption.  In the original GPU-Z picture this would be #2 PCIe connector that can possibly trigger the Pwr limit even though the board power draw isn't maxed out.
 
The power imbalance is why a lot of people complain they can't hit the board power limit they believe their card should be capable of.

But likely this only probably affects the XOC bioses. Since for example, I've tested the stock bios, and here's the results:
 

 
I mean, it's pulling way over 400w limit sometimes even though the 3rd plug is low and the slot also. So if I loaded 450w bios, I would get power caped at those value since my plug 2 is going up to 151w?

You have to lol when the only person providing any useful info is getting called out for not owning that card.

If u want the facts here the are.
The cards running a up9511r controller. The PCB is mass produced so they are all set up with the same config resistors, Which is what sets the balance.
It cant software rebalance the plugs and slot power like the other brands that used digital controlers which just need a I2C command sent to change it.
It wouldnt be a issue if every die was the same but all GPU dies arnt equal. There is this thing called silicon lottery so some will use more power or less power for the same task.
The die is made up of many different parts and each of these parts is also subject to the silicon lottery.
Only EVGA really knows how each part is wired up to the VRM. If one of those parts is really high leakage that inputs going to hit its power limit before the others.
When that power limit is hit the card wont go any further.
 
If you want to see what each inputs power limit is you can use my bios editor.

And yes I do have a EVGA 3090.
There is nothing he can do himself to change it with out voiding warranty.
Really this would of never been a issue if the power limit arms race didnt start and the cards stayed at there intended release day power limits which was 420-450W for the FTW3 cards and 320-366W for the XC3.
EVGA knows this which is why the 500W bios will always be a beta bios since a large ammount of people wont be able to hit that total board power that it advertises.

I've ran your tool, and checked my bios. The max 8pin pl is showing as 135000mW hmm.

Read bmgjet's explanation.  It seems to be the case for cards that utilize uP9511 controller.  Here's my 3080 XC3 Ultra, heavily undervolted so I don't hit the power limit a lot but the two load peaks are Timespy Extreme GT1/GT2 tests.  The green lines (PerfCap Pwr) was seen when 8-pin #2 hits 150W, even though the card's power limit is maxed out the board power draw doesn't hit 366W.  My #1 gets to ~130W max so its always #2 causing the Pwr limit to trigger before the card can hit its board power limit.
 
The other thing is that the PCIe slot draw can cause problems - if you look at the slot voltage there is a drop under load - in my case it goes from 12.2/12.3V to 11.9/12.0V but in other readings I've seen shared like from a 3090 FTW3, it can drop to 11.7V and such.

I doubt the issue happens because of uP9511 controller, although not the best one, and the 12 would be better, many cards have it and it doesn't have this problem and it should work perfectly.

Only 3 brands use that analog controller. (Galax, Zotac on there low end 2 plug cards.) and EVGA. And all 3 of them have people reporting issues of being unable to hit board power limit when using a bios with higher power limit then stock.
The rest used Digital.

Remove the heat sink and read the part number off it.
Or you can look in the 3090 thread on OCN. First post has a table of all the info.

*eats popcorn whilst enjoying a 3090 that knows how to power balance properly* 
 



Its very likely the uP9511 - the controller is as dumb as bricks and relies on an analog feedback loop from the GPU to tell it what to do.  Everything is set once it leaves the factory and there's no way to change the behavior via firmware.  This is very likely why we've not seen any fixes to the FTW3's dying out there, since they can't reprogram the power delivery logic on the fly.
 
Every card using the uP9511 seems to have imperfect power balance - my 3080 XC3 Ultra draws 25-30W less on #1 while #2 PCIe reaches 150W easily...  very much like the picture posted here for the FTW3, but at least it doesn't have a 3rd input that's super weak.  And it makes sense for the FTW3 given what the decoded MCU code showed in programming for the FTW3, the 3rd PCIe power rail was initially meant to be 6-pin ie. 75W capability.  Seems like EVGA changed the connector last minute, but forgot to rebalance the power delivery.  And now they have this big problem with FTW3 cards with no easy answers.
 
EVGA can release all the BIOS updates they want but the card can't magically realign itself physically to rebalance power.  Would agree that if someone was already spending all that money for a 3090 they'd want a Kingpin type card.




More than likely this is the issue. Check Buildzoids video down here at 4:38, same conclusion with that dumb controller:

Yes, I have the same issue, seem to be able to draw 442w highest spike on the OCCT 3d test. With Plug #2 shooting to 158W, while Plug #3 is max 98.6W, won't go past. Looking at the averages, it won't really sustain much above 400w.

The only time I see a low power draw from pin #1 is lowest at 110w to 121watts and the highest is 160watts from pin #3 when I run the OCCT 3d test but when gaming or 3dMark. The lowest from pin #1 is 124watts and pin #3 is 138watts and it is totally a different story when gaming. Here is my log when running OCCT 3d test first and then 3dMark next. I would rather play games than run the OCCT 3d test any day. This is run from system in my signature which I have had my 3090 FTW3 Ultra since Oct. 27th.

EVGA would benefit from a global product manager. She/he could do the type of research end users are doing. She/he would release a statement saying the concern of the user base is heard(regardless of validity), and would then marshal investigation of the issue(providing assurance investigation is underway[whether discovery has occurred or not]). Finally, a result of internal investigation would be published(whether or not a contrary finding was reached).

Does EVGA have a GPM willing to M GPs? I know they have a mascot that authors announcements, and who responds to inquiries in this forum, at least before QC is impugned. But is there actually an entity that takes product management(which isn't marketing btw) seriously?

My question, since my 3080 ftw3 ultra plug 3 is not going past 98.6w, is this RMA worthy? I could try another PSU, but I doubt it will help. But most likely even those 40watts more it could draw wouldn't make much of a difference anyway.

Badboy64, good for you.  It has been well established that some cards have this issue, and some cards don't.  Some more than others.  Yours doesn't have an issue.  We get it.  Like, how many times does this need to be repeated?  Move on.

It won't.

40 watts will make a difference, but probably not a noticeable difference in anything other than a benchmark.  It depends how you use your computer and how close your current performance in your use-case is between acceptable and not acceptable in your eyes.
 
I probably wouldn't think that RMAing it is worth the hassle and expense.  But that's just me.  You do your thing.  I kind of doubt EVGA would accept that warranty reason anyway, so this is probably just a discussion of theoreticals.
 
As far as theory goes, this situation is not optimal.  But what can you do?  Ignore it, RMA it, or use a different BIOS which isn't officially supported by your video card.

If your card works and your getting with in the normal range of 3080 performance, No.

Had to rma my 3090 ftw3 ultra from day 1. Pin 1 was showing over 400w. Pin 2 was 15w and pin 3 was 0.5w. Lol.

Also it never would leave idle clock speed. Crazy stuff.

Re: 3090 FTW3 Ultra Uneven Power Draw Across 8-pin cables? 2021/02/16 05:24:49 (permalink)
I submitted a support ticket and this was the response:
(I should clarity this was in regards to a 3070 FTW3 Ultra)
 
"Thank you for reaching out to us regarding your graphics card. These connectors will not require an even amount of power as these connectors power different components on the GPU. This is normal behavior for your card and will have no affect on the lifespan of your card.

Please let us know if you have any further questions.
Regards,
EVGA"
Now my daughter has a ASUS Strix 3060Ti and I checked her power draw using GPU-z and it was being distributed evenly between to the two 8 pin connectors unlike mine which has a 51w disparity. hmmm.

Badboy64, good for you.  It has been well established that some cards have this issue, and some cards don't.  Some more than others.  Yours doesn't have an issue.  We get it.  Like, how many times does this need to be repeated?  Move on.

I could try another PSU, but I doubt it will help.

 
It won't.

But most likely even those 40watts more it could draw wouldn't make much of a difference anyway.

40 watts will make a difference, but probably not a noticeable difference in anything other than a benchmark.  It depends how you use your computer and how close your current performance in your use-case is between acceptable and not acceptable in your eyes.
 
I probably wouldn't think that RMAing it is worth the hassle and expense.  But that's just me.  You do your thing.  I kind of doubt EVGA would accept that warranty reason anyway, so this is probably just a discussion of theoreticals.
 
As far as theory goes, this situation is not optimal.  But what can you do?  Ignore it, RMA it, or use a different BIOS which isn't officially supported by your video card.




Would you mind explaining where could I find some information about "BIOS" helping with the issue of plug 3 limitations? If the bios is able to fix this issues, why doesn't EVGA try to fix this with their own bios fix?
