Bud did you not read the whole thread? I set the record with a FTW3 Hybrid with no mods or flashes bios. It's a none issue. People are basing this assumption off a 3rd pin power draw but they are forgetting that the card doesn't receive all it's power from the 8 pin connectors. It can receive up to 75W from the pcie slot. 150-75 is you guessed it... 75W. So 150(8 pin)+150(8 pin)+75(PCIe Slot)=375W. Leaving another 75W for the 3rd 8pin. The 3rd pin is being supplemented by the slot which usually hovers around 50-60W.

1) This isn't about you.
2) Not all cards have this problem. Same story for the previous 8 months.



3) The PCI-E slot doesn't provide 75 watts of 12 volt power.
4) Your math only works if the card power balances properly. If your card is one of the cards which doesn't power balance properly, you get the result above.


Is 5% or 10% performance impact substantial in your opinion? It can't be defined. It depends on each person. If I paid $1400 for a video card, I wouldn't be able to accept it. It's especially embarrassing that EVGA didn't fix this same problem when it released this new product line.

Let's see core clocks, and voltages from these settings? What are your afterburner/precision settings? If you're slamming all sliders to the right you're doing it WAY wrong.

He doesn't have a 30 series card.

Because you can't get one or at least not at scalper pricing? Other then that, no reason except you just don't need one. It surely can't be because of performance of these cards.

Thanks man, looking for the HWiNFO average reading.  From what I've seen so far these cards pull 40-50w less than my 3080.  Prove me wrong.

Pretty close.  Lower peak, but same average.

Wow really great work, much appreciated.  Seems to be running just dandy, regardless of the power balancing being a bit strange and the warm temps.  Thanks!!!
 
One thing that's kinda sus is the ICX temp readouts and the mem junction temps.  Your ICX temps are within about 10C-25C of mine and the mem junction temps are identical at 84C.  But a 30C core delta.  Yeah my hybrid fan setup is very effective, but that is strange.  GPU core power ~250w if I'm reading it right.  I'll bet when someone pulls one of these apart they find inadequate pressure on the die and thick layer of thermal paste.  Just a guess.

Yea it runs stupid hot. Note though my ambient temp was 25-26C during that run. IMO that's the real disappointment though. I'm either going to build another loop for this machine or at least buy the hybrid kit.

Also though, the hybrid doesn't pass water over the mem directly, so it won't be as effective at cooling the mem as it is the core.

The memory is cooled by the Hybrid cooler and it works pretty good. I have one on a GTX 1080 Ti card and was very surprised at how well it does.

Do these cards all have thermal puddy rather than pads now (EVGA) ?

If it has pads then EVGA could have chosen some are to thick or too stiff as they will change your core pressure. At least they do in water blocks. Seems like I've seen EVGA using puddy though.

Here is mine while playing Cyberpunk. Assuming that it shows PerCap reason as power limited due to the imbalance between the rails? Or is that a reference to ~400w being pulled in total?

Is the 3080Ti 400W or 450W ? If its 400W you simply hit the 400W Power Limit....

No idea on the pads vs. putty, but it seems like something that could go out of spec in manufacturing or procurement and not get caught in QC, due to the temps not being a huge difference and hard to measure pressure once mounted.  I usually like to blame people's poor case airflow, but we're seeing excessive reports with poor temps with the 3080 Ti FTW3 Ultra and they should have the same temps as the 3080 and 3090.

On the 400w bios with the slider maxed to the right I am seeing 147.9/158/81 with a slot max of 52.1. 
 
And fwiw, temp max is 81.6 gpu, 87.1 hot spot, and 90.0 memory. 

Just to clarify, the "400 watt BIOS with the slider maxed to the right" is 450 watts. Why call it a "400 watt BIOS"? Maybe "default BIOS" or "normal BIOS" would be less confusing.

Does it matter the order of cables from the PSU?
