Been following this thread on the PCIE power concerns as well. Mine pulls about 73-78v and fluctuates all the time under load. I have an Asus Rampage 6 encore board with supplemental power for SLI connected at the bottom left. Does that connection lessen the risk for over volt damage with one card installed?

You're totally fine and yeah you're offloading some of the load to that supplemental power cord.

does anyone know why it will not let me run the update file for the 3090 ftw3 ultra it wont run the normal or the oc and i tried everything i can think of just seeing if yall know anything

Try downloading the .rom file and using nvflash in admin mode instead.

That being plugged in negates the possibility of frying your 24-pin at the very least.

Sorry if this was asked before. Any difference between FTW3 Ultra and FTW3 Ultra Hybrid BIOS?

Got an air one on the way and the hybrid kit is already here so wanted to know which one I Sphinx update to.

Also, will it void my warranty if I update to the Hybrid BIOS (assuming it’s better)?

I thought so, but there’s so much information in this thread it’s hard to be certain. Wonder if the lack of extra power connections on some motherboards has perhaps contributed to some of the issues encountered?

As I still have my 3090 FTW3 Ultra along side my Strix O24G I can definitly tell you that it didn't change a thing.
I've plugged a 6xpin PCIe on my motherboard (to add power to PCIe) to see if anything changed.
Result: I was at 76-80W on PCIe before and still 76-80W after the 6 pin was added. Still locked at max 400-420W on the FTW3 (and most of the time at 380W)
 
My strix does 480 most of the time and sometimes goes to 490-500.
 
Here is the verdict. The card is broken. It's probably not fixable by bios (else it would have been done a long time ago). I'm waiting for my strix waterblock, then I'll remove the FTW3 and RMA it until it reach the proper 500W, as many time I'll have to RMA. Once the card is at a good 500W or close, i'll just sell it and never buy EVGA again before a ****ing long time :)

At stock bios ''normal or oc" its ok those watts.
The xoc 500 beta bios is another long story
Supposed to be 500w max.
If your card work and can manage 450w at stock bios probably you should try flash the xoc beta .i guess it will work perfect to your card

I have flashed with XOC 500W, no change.
 
I am unable to get a sustained OC in TimeSPy (Same in Heaven Benchmark)....
 
In games this is ok, but in those benchmarks, impossible.
 
How do people do to overclock this card in Timespy ??

Saying it doesn't change a thing is wholly inaccurate.
The 6-pin being plugged in is taking load off the 24-pin, as I said in my reply, so it IS doing it's job & making sure that the PCIe slot drawing over spec is not going to over-draw on the 24-pin & melt it (Note this is extremely unlikely to happen with one card unless you're running LN2 & drawing 90+W on the slot, but if you're running SLi, it could become an issue, which is why the supplemental power was added to begin with, as was discussed a few pages ago in the thread, which is why the topic is being discussed).  It's not "taking the load" off the PCIe slot, that's not what it's designed to do, it's designed to supply power directly to the PCIe interfaces and take load off the 24-pin.  The power draw wouldn't go down because of it, that's just simple power logic.  The card will draw what it wants to pull regardless of what's plugged in where.  The only way to truly negate the issue of it drawing over spec would be to fix the BIOS that's telling it to hit/draw over the power spec of the slot.
The sole purpose of the 6-pin or whatever type of supplemental power it is is to make sure the motherboard doesn't die.  It's doing exactly what it's supposed to.

I've had this Beta BIOS running for a few months without issues (not even overclocked - somewhat to my point).
 
I finally got around to installing EVGA Precision and it simply would not launch without forcing me to update the BIOS. I finally caved and let it update. Is the BIOS it updated to actually newer than this, or did the one Precision forced me to install revert to the standard power limits?

A search would find the answer as it is asked nearly every day on this forum. Well, maybe not in this particular thread about the XOC VBIOS.
 
It's not a VBIOS update, it's a MCU update for the RGB/fan controller on the card.

I'm rarely on the forums, but did do the due diligence of trying to find driver versions. This would also explain why a reboot wasn't required. Thanks for the quick response!

By the by, did some fiddly-dee with stuff...
 
Got up to ~510W draw - 86W from the slot O_O And not a single 8-pin was at 150W.  So this card I have definitely has load balancing issues indeed.  Bright side, it maintained 2130MHz & passed 3DMark at that speed... didn't get a higher score because I'm apparently getting DRIVERed - 80pts lower than my personal best despite the higher speed.
 
Reset the card back to it's stocky mcstockness, not sure if I'll RMA it because of this lack of being able to balance properly or not, think I'm going to contact support & see if this is something I can actually get approved for an RMA for, because when it's running "regularly" with the "500W" XOC Beta BIOS installed, I'm seeing PWR as low as 420W despite having the slider maxed, because of the slot hitting 76W at that low of a draw, and that's resulting in downclocking that negates any offset I have put in.

Yeah let us know if that is something you can RMA for or not.

This can be fixed by simply closing 3dmark, closing steam and loading steam again.  Run port Royal and look at the first 3 seconds of the bench.
You should know from the first 3 seconds if your score is going to be good or not, by looking at the FPS.  If it's lower than normal, your score is going to be lower, then close and exit steam again and reload steam and reload 3dmark.  Keep doing that until your score is back to normal.  Sometimes I've seen it take 4 attempts to get the FPS 'back' to normal.  And that's with no other programs running (besides Hwinfo64 and GPU-Z).

GPUZ power draw max => 269W.
 
But OSD of MSI afterburner shows power max = 430W.
 
I don't understand how my card runs at stock settings in timespy when overclocking it.
In games, at least modern warfare, BFV and black Ops cold war, the overclocks are sustained, so apparently no issue in games.

Don't confuse "GPU Chip Power" with "Total Board Power"

I have install my EK waterblock on my rtx-3090 ftw3 ultra and update my port royal score 14 766, i will do more test later to try improve my performance.

update my score again : 14 934 using the gigabyte 2x8pins 390 watt bios :)

Is that bios better than XC3 ? Can you share

The only difference that I noticed was that it doesn't show the iCX sensors like the XC3 VBIOS does. I didn't get any additional overclocking headroom from it, same GPU temperature, same old same otherwise. If I ran a really good loop that may not be the case, but with a hybrid cooler it didn't make any difference.
