well I called EVGA support and as expected there was nothing I could do from here to troubleshoot the RGB. their suggestions were the same as what I've already tried (reseat the GPU, power cycle the GPU, etc).
 
The started a cross-ship RMA for me. apparently the crosship now requires 2x retail price lol, so I'll have to put 3k on a CC or something. which is fine. I don't want to do the loop teardown more than once so this was OK for me. at least they're paying the return shipping and providing me a label with the new card.

Hopefully the replacement works correctly.

Hi, could you please post here your results after you receive a new card? I am also aiming for the hydro copper, so I'm slightly intrigued by this thread. Thank you.

I definitely will. If I have the same issues with the new card, I’ll have to think hard about the platform and what the issue might be

I received a 3080 xc3 gaming air cooled version Saturday. 
 
My card also hits power limit at around 300 watts. I see occasional excursions to about 320. Interestingly, watching the power usage reported by precision x1, it registers the 320 watt usage as 104%. 
 
The PCIe slot seems to peak at about 66w, and the two pins get nowhere near 150. 
 
Very interested to hear how your testing on your new card goes. 
 
Pretty interesting behavior.

got the new card. and it seems to have fixed the issue. the RMA reason was RGB being non-functional, and the replacement works there, so RMA satisfied.
 
as far as power consumption. it seems a lot better, and in line with what xReason reported. now pulling 335-340W while running Kombustor (vs 310ish before), and running ~300W running furmark (vs 270W before). there's still some behavior preventing it from going to 350W i think, but it at least seems to be in line with the others now.
 
in general, I can see the card pushing a bit more clock, and pulling a bit more power. definitely something wrong with the old card. I'm almost glad that the RGB issue popped up to give me an excuse to RMA.
 
oh and even though the replacement card came in a retail package, the terminal top area (where the RGB logo is) had a good amount of scuffs on it, underneath the protective plastic film. probably why this one was set aside for RMAs...

I am having the same issue on my 3080ti XC3 Gaming. It seems to tap out at 304 watts max and not the stock FE of 350watts. Has anyone found out a solution or is a rma the only way to fix this issue?

I think it could be fixed in the BIOS, but EVGA doesnt seem interested in giving it any attention. since the XC3 owners are a small minority, there likely wont be enough users asking about this to get them to take any action.
 
RMA will be the only way. but,
 
1. you'll have to convince them it's a problem (they'll say things like "we don't guarantee power draw" which is an asinine oversimplification)
2. you run the risk of the replacement card performing the same way.
 
but the sooner the better. they'll pay for the shipping costs if you start the RMA within the first 30 days or so. I paid the 2x MSRP collateral because I wanted to ensure I get a totally separate card, and I only wanted to drain and fill my loop once (hydrocopper card). but you can do a standard RMA too, if you can deal without a card for like a week, they should still send you a shipping label though, make sure you ask if they don't mention it.
 
good luck.

I will contact them about them, =/ hopefully they release a simple bios update and I don't have to do RMA. I am wondering if any other 3080 ti xc3 gaming user is having the same issues

Just noticed that the Normalized Total Power is maxing out at 100% while Total Power power is staying at 88 maxed. So whatever Normalized Total Power is, that's what's capping the card it seems.

Got my 3080 Ti XC3 (3953) card today. Have the same low power delivery issue. I also bought a Hybrid kit for it. Installed the Hybrid kit and the Hybrid bios, it made zero difference in the power delivery.

I think that just indicates it's hitting a limit other than the tpd.

Yeah, something is drawing power somewhere which I assume it's the memory. In other news, if you disable the LEDs on the card, you can squeeze a bit more power for the core. Just interesting that it maxes out the slot at 67 watts and 8 pins connections stay at 120 watts max.

Power use is determined by the PCIe slot it seems. It’s like when it maxes the PCIe slot, it inadvertently throttles the whole card, which prevents more from being pulled from the PCIe cables even though there’s headroom. Seems to be a power balancing problem. EVGA should fix the bios to allow more through the PCIe cables or not throttle the GPU so early

Neither of my PCIe power plugs are pulling much over 110W and the PCIe Slot is around 66W. GPU-Z says PerfCap Reason Pwr.
 
PSU is 1200W single rail.

Someone on overclock was saying the cards are actually pulling more than we think and none of the software is reporting it correctly.

That was my FTW3 though.  Would have to take the same measurements for the XC3 to see if it's the same or not.  It's not even proven that all FTW3 draw more than what is indicated on 8pin #2.

apparently the crosship now requires 2x retail price lol, so I'll have to put 3k on a CC or something. which is fine.



The policy seems to be in flux, so day to day I don't know what the current policy is.  But, basically, the issue EVGA was having is that people would buy 1, do an RMA cross-ship to get a second one, scalp both, and even though they lost money on the collateral, they made money overall with the scalping.  So, the double collateral would have been used to prevent the scalping and bleeding of inventory.

Yeah I know why they implemented it. Still hurts dropping $3K on my credit card, even if I get it back lol.

I don’t think the card is misreporting power use. I get the same readings through nvidia-smi in Linux. Which is the most accurate. And when I got my replacement card, it was reporting more power draw (still not up to the limit, but better) with the same exact software in both Windows and Linux. It’s 100% the card and not incorrect software readings. I also saw slightly better performance and higher clock speeds with the card that was able to pull more power.

still no word from EVGA on this. multiple people with the same issue now.
 
We need one of the big Tech-Tubers to cover this. a head to head XC3 vs FTW3 (without any crazy BIOS, just the stock ones) would be eye opening and might put some pressure on EVGA to publically address it rather than sweep it under the rug.

Yeah, when disabling the LEDs gives a slight boost to core, you know for a fact the card is very power limited. Kinda crazy, just let it draw an extra 50 watts from the cables 😐

Just got my 3953 email today. How much does this power issue affect the performance of the card?

Basically if your card has the power limited at 300watts or so, expect slightly below a 3080ti FE  which scores about 19000ish. My card is scoring at 18000ish back to back. There's no overclocking room for the card other than undervolting to get better power usages and clocks. You can check using hwinfo or gpuz how much power is being used up by the slots and the two 8 pins to see if it's affecting your card too.

So you have the power issue and you're seeing around 18000 vs the 19000 of the FE. How much power are you drawing during this benchmark? How does the card perform vs a FE or something in non-synthetic situations (i.e. games)?

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)
