My friends, they've ignored this for 2+ months on the FTW3. Time to stop being an apologist (hopefully wwxww can learn to read his own definition), and understand that EVGA ****ed up hard this generation and hardcoded an analog ratio in the load balancer chips that they cannot change on these initial/1st generation PCBs.

Pretty solid explanation you give here. Do you know why some cards seem to be affected while others are not?

I am unfortunately having the same issue :(

Can you describe your issue?

Can't believe I have shunt mod a "LN2" card to get the advertised power limit. 110% power target is the upper limit with a 460-470w board power draw in timespy extreme GPU test 1. GPU test 2 will see some spikes over 500w but stays well below 99.9% of the time. PCIE power draw typically 55-60w. Strongly considering an RMA, will wait for my ftw3 block first I think. Can't go back to air cooled noise hell with this right now.

Lol. Shunt modding isn’t going to help you hit the max power limit. Shunt modding removes power limits. To hit the 520w limit on the kingpin card you need to increase your voltage using the classified tool.

Shunting moves the power limit up, doesn't remove it. Was referring to shunting pcie only in this instance. Classified tool isn't going to change this.

Never hit 520. Pwr cap. Timespy extreme

From the 2080ti kp xdevs page: 
 
"Make sure to max out power limiters to ensure best performance, even when reported power levels looks same. Now you may ask, how can I get card to show advertised 520W in Precision X1 or OLED? Well, that’s a lot of power and Precision X1 will give you only averaged value. The performance will be capped significantly way before you’d be able to reach averaged 520W power reporting in PX1."
 
 
Following TiN's word's above: is 520W not a limit, rather than target?
 
Also, I'm afraid I can't lend much credibility to the hardware rev. theory being crafted in this thread: I believe I have one of the first cards shipped (processed before thanksgiving) and my pcie slot draws are well under the spec.

I think we found the problem.

You guys may want to look into this a bit more carefully than what you did last time...(with the FTW3 cards).
 
Looks like Kingpin cards are throttling because of WAY too low VRAM (MVDDC) and chip power limits...
 

 

 
Furthermore, why is eVGA using 92W for VRAM (MVDDC) limit on half of their SKU's--including KINGPIN cards, and 121W for other boards?
Why would they use such a low MVDDC limit on a king pin card?  Asus seems to be using up to 162W for MVDCC (FVBDD) on a few of their cards...
 
I posted many pages back, when someone did a huge batch of tests and made an excel sheet with the power rails posted, that "MVDDC" might be triggering a power limit.  One person seemed to take note but this seemed to have just been completely forgotten and it went back to PCIE Slot again....
 
But according to the Vbios dump, the PCIE slot limit is 82W, not 75W....

The problem is, changing the power limit slider is ONLY going to change the TDP limit with respect to the 8 pins+Slot power.  TDP is specifically 8 pin #1+8 pin #2+8 pin #3+PCIE Slot.
The TDP slider doesn't change the internal power rails at all.  It looks like "MVDDC" and "Chip Power" are supposed to have a "default" and "max", but they are both the same--which means they don't change at all.  Those limits either need to respond to the TDP slider or be set higher by default.  (and note: there are shunts onboard for both Chip Power and MVDDC....)

So does this essentially mean it would still need an RMA or is that something that could be completely tweaked within the Classified tool itself? I tried playing around with the voltages a bit more (even though the card is being RMA'd for the obnoxious buzzing) and the only result was more throttling.

Has anyone used the new classified tool on the 3090 KP with LN2 bios?  Then, emailed Vince for the true XOC bios?  Tool added msvdd(?) tweaks.
 
My problem with my 2080ti KP had been cooling.  With my lazy efforts, I could only cool the GPU to 14C idle and high 30s at load using 1.17v.  GPU maxed at mid 2250s.  It follows Tin's boost/temp tables for his results.  I would think the 3000 series is similar based on Steve's LN2 baselines boost tables he did early on the 3090.

It is quite simple, they revised and fixed the problem on newer manufactured pcbs. As stated, the load balancing chips take an input voltage to determine the ratio so they simply adjusted this input voltage, or similar. It's already appearing more and more with newer FTW3s (an increasing number of reports that do 500W with the XOC bios), the very simple way to check is if you pci-e slot is drawing ~75+W or 50-60W under time spy extreme load. PCBs are manufactured in batches and there certainly are multiple batches of KPE PCBs that have been created, so it follows that you can reasonably assume the newer ones have the correct balance while the older ones made before the whole FTW3 XOC debacle (or whenever EVGA became aware) still have the problem. 
 
My KPE edition finally arrived today, so I will be testing the PCI-E draw and asking for an RMA if I have this issue. I'd recommend all other KPE owners do the same (run your card under TSE on 520W bios and observe PCI-E slot power draw in GPU-Z or HWInfo), to hopefully pressure EVGA into providing more support or clarifying if there is a misunderstanding somewhere.

I need you guys to do some testing and REPORT your TDP Normalized vs TDP % vs "TDP Slider % set".   I am Falkentyne on overclock.net, by the way.

No one is going to be stupid enough to invalidate their warranty at this point. I think they were hoping people would request the no limit bios so they wouldn't have to RMA cards.

I ran the true xoc vbios on my card, and pushed 625w through it.
