Hello all. I did to my FTW3 Ultra the rebar automatic update via X1 on the normal bios. Is it possible to flash the XOC bios here posted (BIOS 2 (OC)) in the OC bios (switched to OC)? Is it needed anything like nvflash or anything like that? How much W does this bios allows? I appreciate any info. Thanks!

I just purchased the 10G-P5-3897-KL as was hoping to use the 450W bios on it but as others have said the KL isn't working. I AM HAPPY to wait for an update here for it but if there is no fix for this issue planned I would like to return the card. Other brand and less expensive card I could have without the 450w bios is about the same performance. I was specifically interested in the ftw3 ultra because of this 450W bios. I thought the KL cards only impacted mining which I do not care about. Thanks.
 
I got an answer to this in case anyone has an LHR card. The 450w bios can be found here:

Are we getting similar BIOS for 3080 Ti?

Pretty please?  Need to get that 3rd 8-pin power up.

Is anyone hitting power limit after installing XOC bios (on OC side of switch) ?. I got power limits when set 1050mv@2220mhz and run some tests like 3dm, and my 3rd power connector shows little usage, like half of the power 1 and 2 uses. Is this normal? My version is the non capped one, KR 3080 FTW3 Ultra.

Sounds about right. 
PCIe delivers 75W of power, 8Pin connector - 150
75+150+150 = 375, so you're 75W (1/2 of 150) short, that's what you see on 3rd.

That's a common issue, even with the 450w BIOS the card hits the power limit and throttles at 400w. 8-Pin #3 shows half the power draw of #1 and #2. My 3080 FTW3 is the same.
 
There are tons of reports of it in this thread, or in other threads on this forum e.g:

There is no known fix or workaround and EVGA have not officially acknowledged the issue (despite acknowledging a very similar/identical issue with the 3090 FTW3).

Ok thank you very much for your responses. Yes, was forgetting about the 75w that pcie provides, so that's giving me the power limit ok. If the 3rd 8pin connector is basically a 6pin as other says, this is really a drawback from EVGA. Even worse in the case of 3090's. So there should be no point over a higher wattage bios for this cards, if this is true. Very disappointing.

My first 3000 series card was the 3080 FTW3 Ultra, I really can't remember me having that problem with that card tbh.
My 3090 however, could never reach 500 watts (with the 500w XOC bios) so I rma'd it. I have not seen EVGA offer that for the any other cards than the 3090 cards though.

Yea, it seems that some cards, possibly more often the earlier cards, will happily pull 450w and pull from all 3 8-pin connectors equally. There is some speculation that it was a hardware level change EVGA made to reduce failures (red light of death?).
 
It doesn't appear to be something that relates to the BIOS, as the voltage controller isn't programmable, and decides based on various physical readings. Seems to be hardware related, as EVGA are RMA'ing and replacing 3090 FTWs that have the exact same issue.
3090 FTW3 Ultra Uneven Power Draw Across 8-pin cables? - EVGA Forums
 
Its certainly is an unfortunate situation, since as far as I was aware before I bought this card (and passed my thermal pad modded 3080FE to my brother) I thought it was a 450w card not a 400w card. Right now all I'm gaining is 30w of power draw, while having to deal with that all 400w of heat is ejected into the case, while with the FE it was exhausting at least 150w out the slot.

So the 3090 FTW3 Ultra v1.0 (the one that has the red light of death fix) has this same workaround... I had one and tested and it was pretty similar to this 3080's FTW3 ultras, the 3rd power connector would always take less input that the others, and never reaches the max supposed power. What a move from EVGA.
