Would you mind explaining where could I find some information about "BIOS" helping with the issue of plug 3 limitations?

Posted in a different similar thread:

The only way is to flash with a 2x8 pin bios as the KFA2. 390W bios.

It bypasses the power limit and you can boost with expected frequencies and voltages.

At your own risk of course...

Since I don't own the card, obviously I can't validate that it works. That's just what has been reported.

If the bios is able to fix this issues, why doesn't EVGA try to fix this with their own bios fix?

It doesn't really fix the issue. It just breaks power monitoring of PCI-E plug #3. It's hacky. BIOS is reviewed and authorized by NVIDIA. If EVGA wanted to release an official BIOS which breaks power monitoring of plug #3, I don't think that NVIDIA would ever approve.

I am confused by the support response from earlier.  Are they saying this is not an issue?

That is what support basically told me with my 3070 FTW3. Which I almost do not believe or which is kooky considering I got my daughter a Asus Strix 3060Ti and has proper balancing between the two 8-pin power plugs. I don't understand why both wouldn't be used equally if other board manufacturers can do it, why can't EVGA?

If I am characterizing this correctly, my GPU is at 100% and so should be drawing full power.  Also curious by GPUz would say there is a performance cap.  I am a bit new to this so it could also be my understanding.

Oof! That is absolutely terrible! I would RMA it. 100%

If EVGA won't approve the RMA, fight them. Their warranty covers defects in design and manufacturing.

If EVGA still refuses, you could try returning it to whomever you bought it from for a refund, or sell it to someone who doesn't care, and try buying another one and hoping for better luck.

I guess I'll live with my 430w power draw and 100w plug 3 limit :) It works pretty well in games anyway. Maybe EVGA will find a way to fix it in a bios update or something one day.

Any ideas on what is going on with the 8-Pin #3 Power draw on my new 3090 FTW3? These were the max numbers on my first Port Royal run on my card. Default settings (no OC), running the OC Bios (same results with the Normal Bios). Power Supply is a 1300 G2. Please let me know if I missed any pertinent info that you guys need.

Thanks!

Man, sorry for crashing in... Maybe this is old news already, but after seeing your post I made some tests here with my 3090... In Furmark the 3rd 8 pin cable stayed at around 70W and total board power around 320... Cables 1 and 2 was getting 120W give or take. Ok... I installed OCCT and used their stability test for vga... well... now things got a lot more interesting... Total card power raised to spikes of 450W (I'm using the stock "OC Bios" switch) and all three 8 pin power were using full 150W. So... Maybe it's by design... The third one is the last one requested, just in case of extreme power usage.


Just my 2 cents... Sorry if this was already mentioned. I hope it helps.

Just tested your theory and I still get a discrepancy of 30 to 40w difference even in OCCT with Perfcap of PWR. Power draw on pin #1 12.0v on pin #2 11.9v. wonder why the dip on pin 2?
Damn, I was hoping that was the case for me.

Add my 3090 FTW to the list. Getting about 140, 150, 75, Where's my other 75 watts evga? Card still runs ok but it could be better if the 3rd 8pin wasn't gimped.
 
I wonder if this is even fixable without some sort of hacked bios or using a 2x8 pin as bios as a work around. Such a shame that they can't get it right.

Hot take: If the power balancing works properly, it should be able to balance throughout the entire range of loads and applications.  I realize that it doesn't really matter until you reach the max on any individual input, but it is silly if it can't power balance at lower loads either. Observing that it doesn't power balance properly in Furmark but can power balance properly in OCCT is kind of silly.  This is just another indicator of power balancing which isn't effective.  Like I say, I realize that it doesn't really matter until you reach a max where a power limit is being imposed, but, you see this is an indication of an implementation limitation.
