I flashed both 94.02.42.80.27 (Rev 0.1 500W) and 94.02.42.C0.02 (Rev 1.0 500W) VBIOS to my Rev 1.0 card, then ran 3Dmark multiple times to try to get Time Spy score as high as possible. I got ~1% higher score with 94.02.42.80.27 VBIOS. 
 

A 1% difference is within margin of error for the test.

Rev 0.1 500W VBIOS pulls 505W MAX and Rev 1.0 500W VBIOS pulls 478W MAX in Time Spy test. However, I notices some display error (some lattices with abnormal color) when loading 3Dmark (not in Time Spy test) with Rev 0.1 500W VBIOS on my Rev 1.0 card (it returns normal after flashed to Rev 1.0 VBIOS, so it can't be hardware issue). I think that's a point why Jacob suggested not to flash Rev 0.1 to your Rev 1.0 card, there could be some compatibility issues since Rev 1.0 card has different PCB design, DrMOS and PWM controller.
Here is my Rev 1.0 card. (Original link https://ibb.co/zn396mj)
 

no it's not that it's because the 500W+ VBIOS will load the heck out the PCIe cables from the PSU at 160W+ easy

No,  
  500W Rev 0.1 VBIOS on my Rev 1.0 loads average 155W thru 8Pin#1 & #2 and 120W 8Pin#3.
  500W Rev 1.0 VBIOS on my Rev 1.0 loads average 150W thru 8Pin#1 & #2 and 105~110W 8Pin#3.
  520W KP VBIOS on my Rev 1.0 average 160W thru 8Pin#1 & #2 and 130W 8Pin#3.
  Only Kingpin VBIOS can pass 160W+ thru 1 PCIe 8Pin easily.

Nope, the Real XOC I mention above flashed to the New Rev 1.0 cards will pull what I say. It's a great VBIOS and if you put the card on water will rock!!!

Hi,
 
Got hold of a EVGA RTX 3090 FTW3 Ultra to start some overclocking for better performance.
 
I'm quite new to the oc business and I have tried to read as much as possible in this forum about the power balance issue. My card has S/N starting with: 2012 and black lips, have updated the BIOS through Precision X1 and have BIOS version: 94.02.42.80.AD with Re-BAR enabled in BIOS slot 1 (Normal) and BIOS version: 94.02.42.80.27 with Re-BAR enabled in BIOS slot 2 (OC).
 
Could someone please write a simple tutorial how to best test if my card has power balancing issues and if it draws to much power from the PCIe slot?
 
Do I have the right BIOS versions, should I run the BIOS switch in Normal or OC mode? Should I do the overclocking with EVGA Precision X1 or MSI Afterburner and what oc settings should I use for either software? Should I use GPU-Z or HWMONITOR to monitor how much power my card draws from the different connections? How is the total power calculated? What benchmark or test software should I use to run the power load test, is Port Royal the only one that's good enough, is there any ok free alternatives since 3DMark Port Royal costs money.
 
Thanks in advance!

 
Anyone who can point me in the right direction, please!
 

So, my card is rev 0.1 pulling about 450watts. I want to water cool my pc. Shoould I rma to get a rev 1.0 to be able to get the 500watts as supposed? Thank you!

RMA it. I've been through 2 RMA's now with Rev 0.1 cards each time. Hoping I get a Rev 1.0 in the mail today.
Rev 0.1's are very finicky. I've had Halo: MCC cause one to die. The second one I just immediately RMA'd through 3090oc@evga.com
 
Edit: Nevermind another rev 0.1....

The thing is, how much of a performance improvement will I get? Atm I get 1980mhz stable... watercooling a rev 1.0 which pulls 500w, what MHz will I be able to get? I do get a score of 14360 on Port Royale...

You will get 14800 port royal and the benchmark will run with an average of 2115mhz

Thanks for your help. I found a bios on the forums here "https://forums.evga.com/m/tm.aspx?m=3407542" from EVGA that allows for the full 500 watts. It is ama click and go flash which is handy. Has anyone else tried this and what experience did you have? A great community here

Most people use GPU-Z to see the PCIE slot and PCIE plug power, while using something that really loads the GPU - like Time Spy Extreme, Doom Eternal (max settings, no vysync or gsync), or the like.

PCIE slot power shouldn't exceed 67W as read by GPU-Z. I'm tired of writing out why, so in short - GPU-Z only reads 12V and not 12V + 3V power. If you want a more in-depth explanation, flip back over the last 20 pages and it is bound to pop up.

me too bro, tried to help but people don't read all of those important pages back...
