As the title suggest, my RTX 3080 XC3 Ultra can't maintain the factory 1755Mhz at stock settings. I have my overlay on almost always while gaming and I've noticed that when playing Rainbow Six Siege at 4K 144Hz (native) my XC3 will drop as low as 1725Mhz with it barely averaging just 1740-1755Mhz. This is stock, no tweaking, no fan curves or broken power limit (it doesn't work). The card can't even maintain it's factory 1755Mhz out of box. I've never owned an Nvidia card that didn't boost well above, if not hundreds of Mhz above the factory boost stated on the box. I have a high airflow case with Noctua fans. Room temp is 70F. GPU was sitting at 74-75C. I consider my home cool/cold. If the card were allowed to go to 80C I imagine the results would be even worse. 
 
Something to keep in mind for potential buyers. 

My recommendation is for you to revisit your case airflow, it appears really poor, your temp shouldn’t be that high and indicates the card is heat soaked as thr memory and power runs hotter than the GPU so its throttling.

RMA it.

I was also going to comment on the temperature. I have my PC set to shut off if my GPU gets to 178 F (81 C). My manually overclocked EVGA 2070 Super at full load rarely inches above 150 F (65 C.)

Yeah, every evga card I've ever owned rarely gets to 75 and that's after years of use and overclocking.

Don’t do that! Silly suggestion.... have you set the card fans to 100% and opened the side of the case to see if temps drop and clock stays 1755 or higher? Also - attach a screenshot of you running X1 showing temps and clocks for mem, power & gpu - so 6 chats in total

You don't have to set the fans to 100%. You don't have to install Precision X1. The card is designed to achieve its advertised specs out of the box without installing any utilities and without tweaking anything. If it doesn't, RMA it.

Even if he can (probably can!) get it to boost above the minimum specs via tweaking it, it's obviously sub-standard silicon and any legitimate excuse to RMA sub-standard silicon is good for the owner.

Try reinstalling Turing GPU. 
 
Ampere requiring a 100 MHz underclock is hilarious. So much for the +10% over 2080 Ti @ 1440p, now it's +5%. 
 
 

Using EVGA 1600w T2, PSU is not the issue.
 
Again my home, and case are very cool. My 10900k runs 35-50C under gaming loads at 5Ghz all cores. Ram, motherboard, chipsets, etc all cold. Airflow is not an issue. You cannot compare 20 series to 30 series GPUs. Different coolers, different GPUs. But if we must, my 2080 Ti FTW3 ran around 58c under load overclocked heavily. This GPU just has a poorer thermal solution and possibly runs warmer due to the increased density of the GPU. If you must compare my GPU, go watch Jayz2cents latest video where he compares an FE to a XC3. The XC3 at stock was hitting 82c. I hit 75c. If I was in his testing environment my results would be worse as the GPU would throttle back due to Nvidia boost logic. Something to keep in mind as I stated before.

Man, more really really really bad mis-informed information again... swing and a miss, strike two!   you don't have to do anything. you can leave the card with no 8-pins plugged in too... but that's crap advice.  However if OP would like to install it correctly and troubleshoot... and avoid an RMA when it's not a defective card... then OP should listen to people trying to help, instead of you who's wasting his/her time and deliberately trying to cause confusion or generate frustration for the OP.  
 
You don't RMA a graphic's card that quick... try to troubleshoot..  and NO the card won't "just work" if you have horrible airflow... every card will be bad in a case without sufficient airflow, or an underpowered PSU or incorrect drivers, with the wrong fan power curves or a host of 60 other issues.
 
Ty_ger07 - stop wasting people's time... help or leave.

high airflow case with Noctua fans

Take the video card apart and change the thermal paste, hope that makes it better, or RMA it.
Disregard those who say that you need to crank up the video card fans or use an open air bench in order to achieve factory advertised boost clocks. That is simply not true. You don't want to own substandard silicon which you will be stuck with for however many years.

In all seriousness though, I believe that the XC3 variant is one of the AIB cards that is suffering from the POSCAP debacle, although I could be mistaken.

The SP-CAP thing is about instability. The OP isn't having a stability issue. He is having an issue with the video card not achieving advertised factory boost clock when everything is default. That is a different issue and doesn't indicate a capacitor issue.

Other games show this behavior? It is possible that the GPU clock may ramp down in CPU limited situations and/or games. This is a feature to reduce power when not needed.

Looks totally normal too.  I mean you could have a slightly less than optimal TIM application, but there's only so much an cooler can do with a card pegged at 330w power draw.  Boost 4.0 is pulling out a ton of clock at 75C, you could easily add in +90 or +120 and have it be stable.

Normal should be "1755 MHz Boost Clock" according to spec. If he is not getting that boost clock while having acceptable GPU temps then, nope, that is not normal. I concur it is, RMA worthy given the conditions.

Or, he could open up the Afterburner voltage vs. frequency graph while running the game and see how much clock it being pulled out by Boost 4.0...eh?

Irrelevant if it is not operating as advertised. You're repeating a mistake already addressed in this thread.

I can't believe I'm saying this... but I agree with Hemi. False advertisement if it doesn't reach advertised clock. EVGA is really good brand as far as honoring their product, that's one thing I won't ever knock them for.

Why would you preface your comment with nonsense?  Look I get folks wanted some internet glory gloming on to the issue over caps. That entire thread was technically inept as were most of the participants. Get over it.
