So I have this card. it seems to more or less work fine. but there seems to be some hidden power cap being enforced. I have never observed the card to use more then 300W. it doesnt matter what load I use. 3D benchmarks, CUDA compute tests, etc. so far it seems to throttle right around the 300W mark. increasing clocks doesn't help. I ran Heaven 4.0 on loop at 4K with all the settings set to max. looks great, runs fine, but clocks are staying around ~1800-1850MHz and the card never pulls more than 300W, I even cranked the clocks to +150/+1000 and no change, and more commonly around 290-295W. In an O11D with dual 360mm rads, highest temp reported was about 48C. from reviews of other 3080ti models, these cards should be pulling up to the full power limit in these kinds of tests.
 
I've tried tests under both Linux and Windows, with the same results. nothing seems to get the power limit over 300W. this is making me suspect that there is some hidden power cap that's not allowing the card to pull the full 350W and leaving performance on the table. This card allows up to 366W power limit, but increasing it to that still doesn't change anything.
 
Is anyone else experiencing anything similar? Any suggestions on what I might try?
 
Used the 471.11 drivers on Windows

X570 w/ 5950X @ 4.45GHz

other info: while running Unigine Heaven 4.0 @4k with power limit maxed to 105% (366W) on Precision X1
 
GPU-Z:
PerfCap Reason: PWR
Power consumption: ~80-85% TDP
PCIe slot power: ~66W
PCIe 8-pin#1 power: ~110W
PCIe 8-pin#2 power: ~105W
Board power hanging around 290-295W, 304W instantaneous peak
 
but precision X1 shows power draw near 100%, bouncing 98-100ish. there is something defininitely wrong here. why would GPUz report a power limit when it's below the limit? I suspect some funky vBIOS setting/config that's enforcing a lower power limit. can anyone reproduce this on a 3080ti?
 

that sucks to hear. I got 6:00:19 in that gpu queue so maybe if I end up getting one in a few weeks I could look and see if it has the same problem.

Wow, it's a terrible card. I'll give you $800 shipped for it.

It's hitting an internal limit you can't see in the monitoring tools. Try Kombustor. The FTW3 doesn't get much higher than 400w (out of 450w) in a lot of games. But it does get close to 450w in Kombustor. Not that it really helps for gaming obviously.

what internal limit could there be? lots of reviews show other brands cards pulling all the way to the power limit. like the FE card and the MSI cards, etc. EVGA shouldn't be any different. the disconnect between what Precision X1 shows (100%) and GPUz/HWinfo (85%) is really suspect. I think the bios thinks it's hitting a limit when it's really not.

running Kombustor, clocks ~1650MHz, power came up to about 305-315W

When that happened, what are the max on PCI-E, Pin#1 and Pin#2?

Some people suspect the limit is when a Pin# hits 150W everything else stops.

But I don't think that's true because a 3080 Ti Strix was shown to have all the pins at 120Wish and it was capped at 400W still when it should be able to go up to 450W.

I’ve never seen the individual plugs over about 125W

Yea that's not good. Might be worth asking EVGA. I think they will work with you if it isn't even getting close to the default 350w limit.

Might try running DDU in safe mode first and reinstalling your drivers if you haven't already. Although you said you tried Linux too so maybe not much hope there.

A bios does have other internal limits that can be hit beyond the total power and 8pin/pcie though.

ABE can show more of them but can't show which one is being hit. You can see an example here.

It doesn't work with the 3080TI yet though. At least I don't have a version that does.

This is why the KP XOC bios can even let a card like my Zotac 3090 2x8pin card pull 500w+. It has all of those set crazy high.
