I just installed XC3 bios on my FTW3 Ultra.
Freq are really unstable compared to XOC. Benchmark are really lower than with XOC.
In benchmark the freq jump from 1000 to 2200 continusly. What could be the problem ?
Does it possible to lock the boost clock in AB like PX1 ? I didn't see that possibility.

mmm this is quite strange, for me is perfectly working in both gaming and benchmarking... did you reset ab profile before flashing? try ddu and driver clean install after bios flash.

So i have flashed the original bios .15 and .16 again after downloading the newest nvidia driver (no need for the xoc bios) but now my card draws easy in games the 450 Watt(with only typed in +85 core). Hit was with 456 Watt and one hit by 79.8Watt Pcie. So here no problems for the moment. Only in gta the fans are reving wildly...dont know why but it works.
Edit 2. I works also if i only set Powerlimit to 107...

Hello, it seems like the 500w bios works for my card, but I can't go past +150 on the core clock (119% power slide and 100% fan speed, 250+ on memory clock) when overclocking using afterburner to run 3D Mark test, always crashed in the middle of TimeSpy test. I have seen people can do 200 plus on the core clock. Am I missing something?

You're missing a golden card instead of your really good card.

Hi buddy,

Just installed XC3 bios but something im not understanding...im getting 14k on Port Royal while before i was like 12.7k BUT my Board Power Draw is way less than XOC.. XOC was hitting a max of 420W while XC3 is hitting max 310W..

Im also getting higher FPS...

Ahh I see thanks buddy. Yeah thats a great thing ! Just got 21k (graphics*)on Time Spy while before it was +-18.5k

Cheers

Today I received the Power Boost cable EVGA makes, so I'll see if that makes a difference. 

Fans were set to auto... does setting them to 100 make a big difference? Thanks.

XC3 VBIOS on stock air: https://www.3dmark.com/spy/15580398
XC3 VBIOS on hybrid kit (didn't gain much but better temps): https://www.3dmark.com/spy/16982326
I don't have a 500W XOC VBIOS time spy run, as I was more focused on PR.

XOC 500W VBIOS on stock air: https://www.3dmark.com/pr/541625 
 
The difference is temperature with the XC3 pulls around 500W, with ~66 from the PCIE slot (vs that insane 98W of yours (you do know that your card has a 120W PCIE slot fuse, right?)). XOC 500W it'd pull around 78 or 79W from the PCIE slot and power throttle, and I'd see 430 to 440W max total power average most of the time - with an occasional 460W depending on the game.

On the 500watt bios here (OC 3090 variant) my PCI was only hitting 78-79watts, fwiw.

Which is why your card pulls 98W with the unlocked VBIOS (you do realize that your GPU has a 120W fuse for the PCIE slot, right? A spike over 120 and your card just bought the farm). And why I posted my results with the XC3 VBIOS.

@cbaty
 
The bios your using will void your warranty so be careful.
I'm using the OC Hybrid bios (beta) and my scores are close 3090 Hybrid Ultra FtW and RX 9 3900
I peak @ 465 Watts
Time Spy 19155
Port Royal 14143
My OC on the core is 105 and memory is 600

Thanks for the warning. Not the first time I've read it, and it's why I bought the EVGA Power Boost PCI cable.

I'm not sure how a power boosting cable will prevent a fuse from instantly popping when your card tries to draw more than 120W (even an instantaneous spike) from the PCIE slot, bricking your card. But you do you.

I was under the impression the cable feeds power from the PSU to the board, so that the GPU isn't needing to feed as much.. 

The GPU pulls whatever power it needs from the sources available. The sources are: PCIE pin 1 through 3, and the PCIE slot (with a 120W fuse). With the unlocked VBIOS, if your card pulls more than 120W (even an instantaneous spike), POP. Dead card. And with the unlocked VBIOS on it, EVGA is going to not honor the warranty.

Understood. Thanks.
 
Even with the 1000w BIOS, while gaming I hit 80-81watts a PCIe, so I'm not too concerned for my daily use with the 1000w bios. 
 
Gotta pay to play. At least that's what I was told when I was dumping money into my M3...
 
edit: Can someone explain the benefit of this cable for me? Thanks in advance: https://www.evga.com/articles/00600/#:~:text=Boost%20Your%20Power,%2DE%20bus%2C%20improving%20stability.

I'm confused. Isn't Port Royal supposed to crash if memory gets pushed too far? I was just able to push the memory slider to max in after burner and not get a crash or any apparent dip in score. In fact, its kinda hard to tell any score increase from memory vs run to run variance. Same thing in the Heaven benchmark while paused and moving sliders in real time. I'm on water, using an EK block and back plate, are temps making this possible? What am I doing wrong?

Thing is, 80-81 is still out of spec.  It shouldn't be doing more than 75, period.  
 
I'm going to try the XC3 BIOS at some point, I just haven't gotten around to it because I've been enjoying this new monitor :-D Maybe tomorrow, we shall see.

600 watts great scott! (1000w bios)

That's a VERY low score for 600W, +160 core +915 mem offsets.
What happens if you re-run your test and lower your memory offset to +500?  You should be close to 14800 PR with a 600W power limit at those clocks, if something isn't holding you back or you are getting degradation from a too high memory clock.
 
My shunt modded 3090 FE can get about 22100 Timespy graphics score at +150 core / +500 mem, pulling about 550W,
And about 14550-14600 on Port Royal.  These cards seem to be limited to about 570W max internally due to unreported power limits (regardless of shunts used) although a few people claim to have pulled 600W+ successfully.

Yeah man that is low. Something is wrong. I get barely under 19k (like 18995) with the official XOC 500w bios. Plus 150 on core and plus 400 on memory.

cbaty
 
HWiNFO64 says I pulled 600watts as well.
 
I lowered to 500 on the memory and pulled 18675 on Timespy (25 less).

Not sure what else I can change to help the score. I'm using a EVGA 1600 Supernova G2 and 3 separate cables to the GPU. Any tips? Thanks.

Don't keep PX1 or AB open during benchmarks - set offsets / static fan speed, apply, and close.
 
In the nvidia control panel, set High Performance Shaders.
 
Clean boot without any programs running (other than the Futuremark service / Steam for 3DMark to work).
