I've used clamp meters. and yes i did read that post, well before you linked it, last time it was suggested earlier in the thread.
 
clamp meter readings fluctuate a good bit, was he dumping the telemetry and averaging the readings? doubtful since cheap clamp meters dont really have that ability. which means he was eyeballing the readings. you can't expect great precision from a $10 Home Depot clamp meter.
 
he also claims to have "verified with his UPS" but probably didnt take into account PSU efficiency, which will show higher power draw from the wall than what the component is using on the DC side.

re-read my edits. but especially suspect is that he only measured one clamp at a time, and cant dump telemetry. these are big sources of error in my opinion.
 
still no evidence that GPUz readings are wrong IMO. and it's not applicable to the XC3 card anyway, since the limit is clearly the PCIe and not the power plugs.

Well it doesn't explain why several if not all 3080 Tis I have seen DO NOT average, hit and float around their rated maximum TDP like other cards are able to do in the 30 series. The only explanation I have seen is his. So you're free to do your own experiments. He used two different things to do his own readings and that's all we have for now. It's the only reasonable explanation.

It's not the "only reasonable explanation" for the issues we are having with the XC3 cards. These cards are power capped for some reason. It's not because of temp, that's for sure.
 
Neither my 3080 Ti XC3 Hybrid or 3080 Ti XC3 Hydro Copper cards can match a 3080 TI FE card, that's terrible.
 
My Hybrid beats my Hydro Copper.

Okay well 
Understood. I'm sharing with you that other cards visually seem to be power capped in GPU-Z. They, like you, are seeing similar results. The problem seems to be almost across their board for all 3080 Tis. The 3080 Ti FTW3 and Strix are supposed to be able to do 450W if you max the slider up, but they're not averaging that kind of draw, not even close. They might average 400W, the stock TDP they're rated for. That's far from 450W. Is that not a similar behavior to your XC3? You're hovering around 300W which is the stock TDP, even though you slid the slider to max out and you should be getting 350-363W? 
 
Is it hardware? Did NVIDIA have the 3080 Ti designed a certain way to be capped? Or is it software, can we change and manipulate these caps? If it is the latter, it would give hope that a simple update can fix this. If it's hardware, we're screwed. Or is it that we are hitting these power targets, and the sensors are not correctly reporting them?
 
There's a lot to be investigated here with the 3080 Tis. 

The 3080 Ti XC3 cards have a total power draw of 350W, not 300W. The 3080 Ti FE card also has the same 350W.

I’ve done lots of testing and reported all my findings. It’s in the thread. You only need to read it. Long story short, memory controller load plays a big part in the behavior outcome on the 3080Ti XC3 for most cards. Sometimes someone gets a good sample and it clocks up higher (and reports a higher power draw across the board) with accompanying increase in clock speeds and benchmark scores. But the vast majority of 3080Ti XC3 users experience similar power and clock limiting behavior with lower than normal power caps.

But I’ve more or less accepted the situation. Until EVGA addresses it, I don’t think anything else can be gained from more testing other than verifying existing results.

EVGA doesn’t seem interested in addressing it though. Unless it gets the same kind of exposure that the Amazon game issue got, EVGA will likely continue to ignore it because they can. XC3 cards are made in far fewer quantities, and will always be a small % of the cards in the wild as a result. The Amazon game issue effected the FTW3 cards in huge numbers so there was enough exposure that they couldn’t ignore it.

This, I accepted the situation too. It sucks that my card is so limited that I have to overclock at .816 due the my card's limits but at least it's somewhat matching a 3080ti FE by doing that. Still debating if I should do a step up or not but would just like an real reason from EVGA on why the cards are falling into different piles of power draws.

Go ahead and put it in Step-Up so you are not as far back in the Step-Up queue. It's not like you have to do the Step-Up, but have your options open as soon as possible.

Yeah the only thing that is stopping me is the fact I have to pay 10% sales tax 🤣 again.

If you're talking about paying the full tax again, that's a bug in EVGA's system. I called them about the tax deal and they told me when my queue time hits I will only get charged tax on the difference in the card prices.

Oh really? So it's not the full sales tax on the card? If that's the case, then here I come FTW3 🤣

Would you mind giving some details on the settings that worked for you? Did you undervolted to 816mV (that seems really low)? At what clock speed? Any other adjustments you made that worked? Just trying to get a starting point for when I fiddle with mine.
I was already planning to undervolt this card before I read this thread. I am hopeful based on previous undervolting experience that I can shave at least 50-75W off the power draw to make a 300W limit acceptable. I just got the queue pop today and ordered despite the issues. Obviously in a normal market it would be a pass.

I'll be looking at other manufacturers and FE cards instead this go around.

The FE is not better - just different flaws - hot memory being the number one issue, also has a non transferrable warranty.  Zotac/Gigabyte/etc all have their issues too.  MSI is overpriced.  Your only choice if you want about the best you can get right now for Ampere is Asus.  And good luck finding them in stock.  If you want more performance buy a 3-connector card period, all 3080+ cards are held back if they aren't a 3-connector power design PCB.
 
3080 Ti's are also overpriced out the gate and not great value - that's Nvidia pricing them to start at $1199 instead of $999.  3080s are much better value if you can find them at manufacturer's prices.
