It doesn't matter what you run on it, my card will pull 304watts max. Maxing out the pci slot at 67 watts and the two 8 pins at 110ish watts each. From what I am seeing, it's best to leave it at stock clocks and/or undervolt so it stops the sudden clocks spiking and dropping.

Ok, I won't overclock it then. How much of a difference does that 300 watt vs 350 watt power draw make? Does it make it bad enough that something like a 3080 ftw3 ultra could surpass it?


yeah, a 3080 FTW3 overclocked can easily get 19000ish scores


What about a 3070 ti ftw3 overclocked? I managed to get one of those from micro center and I'm deciding whether or not to buy the 3953.
 
(also what benchmark are we talking about? I'm unfamiliar with most of them) 


I am using time spy from 3D mark and 3070 ti scores way below 18000ish (it's about at 15000) so even with the low power limit, it's still better than that card.

How does the power limited card perform in gaming compared to a 3080 ti FE (or a 3080 ti ftw3 ultra)?

Not sure about that, don't have the cards to test that.

Ok, fair. Are there any fps numbers you can give me?

Probably not helpful but I got my 3080ti XC3 Gaming today. Out of the box It drew 350w watts and I got a Timespy of 19550, After an undervolt, I hit 19955 and drew 358W if HWiNFO64 is correct.

Interesting ! How much of under volt were you able to achieve?

I'm currently running it at 1860/875w. I had it at 1875/868w and it passed a few Timespy, but I had a random crash during BFV so lowered/raised it to the former. So far it's passed multiple Timespy extremes and a couple hours of gaming.

Would it be possible for you to share your card's bios? it's very weird how this only effects some cards and not others

Ah sadly it didn't solved anything, thank you for sharing. Just so weird how it effects some cards, and others are just fine. I wonder if it's a motherboard or PSU issue causing the low power limits.

what is the rest of your setup (what CPU/mem/motherboard/PSU) and under what conditions did you see 350W? was it 350W sustained? or was that peak? if 350 was peaks, what were your sustained average power values?

I took this screenshot during Timespy extreme after it warmed up a bit. If there's a better way to get the readings, let me know. Gonna hit the sack atm though.

Thank you for sharing those readings, I will compare it against my own. Now I am more curious why some cards have this issue and others don't.

My 3953 is supposed to arrive next Monday, so I'll contribute my results then.

Just found this thread, having already posted with a similar question on Reddit. (Can't link due to insufficient post count, oops.) TL;DR: I just got a 3080 Ti XC3 Gaming (non-Ultra, non-Hybrid/HC) and it won't use more than 320W in games despite not thermal throttling. It also gets a 18404 Time Spy graphics score, which seems a bit low for a 3080 Ti. (My understanding is a non-OC'd card should be closer to 19000.) It works fine otherwise, so I'm not sure how worried I should be about this in practice, but I figured I'd add my data point here.

Ok so it seems like people have gotten varying results of how much power their card will actually draw.

Yup.  That's the nature of dumb voltage regulation circuitry which is at the will of physical component manufacturing tolerances.

Yeah, but all cards should follow at least a steady baseline which I think all can agree is the 3080ti FE at least. At this point, we are seeing numbers as power draws from 300ish to the normal of 350ish is shows the tolerance for the card is way too wide.

Mistakes were made.  It is a custom PCB.  The baseline is clearly not "steady".  You can't compare something which isn't working properly to something which is working properly and then ask why they aren't the same.  They are different.  One has a design problem.  One doesn't.  The conclusion is obvious.  As you say, the data supports the conclusion.

Would be amazing if more people with 3080ti XC3 would chip in their specs and power draws for their cards. Not even sure if it's worth trying for a RMA at this point

My 3953 struggles to go over 300w no matter what.. Installing PX1 prompted for a firmware update , did it, but still can’t go over 300w

the "firmware" update is not a "BIOS" update.
 
firmware updates via PX1 have nothing to do with clocks or power use. its for the fans and RGB only.

Re: 3080 Ti XC3 Ultra Hydro Copper, low power consumption, hidden power cap? 2021/07/14 08:35:53 (permalink)

im having the same problem. I can't even get to 300w. My 3070ti is out performing it
 


outperforming it how? in what metric or what load?
 
can you post a benchmark showing the 3070Ti getting a better score than the 3080Ti?
 
I can believe some high clocking 3080s outperforming a 3080Ti that's being very power and clock constrained. but harder to believe that a 3070Ti would outperform a 3080Ti, unless something was REALLY wrong with the 3080Ti.

My 3953 struggles to go over 300w no matter what.. Installing PX1 prompted for a firmware update , did it, but still can’t go over 300w

the "firmware" update is not a "BIOS" update.
 
firmware updates via PX1 have nothing to do with clocks or power use. its for the fans and RGB only.


I did a bios update to the Hybrid bios and had the same results when you changed the bios on the first card you got. It made no difference. It's not the bios, it's the card.

I have the impression that certain components of the board are hard wired to certain power sources and it might not be possible to shift the load from the PCIe slot to the VGA cables.
 
it definitely seems to throttle based on load from the PCIe slot only/first. total board power isnt really being factored yet since it's below the limit, but rather hitting a power limit on the slot alone. this pulls back clocks and power use to keep the slot below limits, even though it has headroom via the cables.
 
for example, when I'm running Kombustor, clocks sit around 1680-1725MHz, pulling ~335W. perf cap reason PWR, PCIe slot maxed at 66W. running Heaven 4.0 on loop, it's more or less the same, but ~310W a bit higher clocks 1680-1800ish (varies a lot more than Kombustor), and PCIe slot maxed again at 66W. 
 
but if I run Einstein@home Gamma Ray tasks, it's only pulling 285W, clocks ~1680MHz, PCIe slot maxed 66W, perfcap PWR. so you'd think that if it's only using 285W, and within thermal limits (never over 47C, watercooled) that it should allow higher clocks, but it's being limited really hard. probably something tied to the PCIe slot that's getting stressed and causing the whole card to throttle, and not able to transfer power.
 
with different loads having different soft limits on power draw, I think some loads will just get throttled more than others. I still think it might be certain components being hard wired to the slot, and when those components get stressed, it doesnt just throttle that component, it throttles the whole card.
