ty_ger07The 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.
Turbo-12RI 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.
Turbo-12RAgain, 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.
ty_ger07Turbo-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"?
donnie123But 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?
neteng101donnie123But 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.
bmgjetYou 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.
FeklarIs this accurate? I've noticed something like this. I hope this isn't the case.
donnie123I 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.
MDG73How do you find what controller your board is using?
neteng101Dabadger84*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.

donnie123Yes, 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.
donnie123I could try another PSU, but I doubt it will help.
donnie123But most likely even those 40watts more it could draw wouldn't make much of a difference anyway.
donnie123My question, since my 3080 ftw3 ultra plug 3 is not going past 98.6w, is this RMA worthy?
ty_ger07Badboy64, 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. donnie123I could try another PSU, but I doubt it will help. It won't. donnie123But 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.
