So some quick prelim power draw tests with Furmark and gpu z at 10 min time. On total stock OC bios.

I haven't had a chance to flash the xoc bios yet but this is total stock no adjustments and a 20125 card (China). So it looks as if my stock at least is within spec as it should be.

Is this with the power slider a 100%? if so yes thats within spec. Try it with the slider at 107% and see what the avg is

Yep literally nothing changed. All sliders at default. I didn't have a lot of time with it but I'm going to mess with it more later. Increase power slider to max on stock then test. Then flash xoc bios and test power draw on max power slider.

the data we need is: on XOC BIOS with power target at 119% (500w) can you actually draw the 500 watts?

I'm simply referring to the people returning their cards due to being over spec on the pcie slot on stock oc bios.

I just got my 2014 Taiwan 3090 FTW3 Ultra this afternoon. I was initially disappointed that it's wasn't 2012 China, but a quick check indicates that it's working fine. Setting power to +7% with Afterburner, I'm seeing a solid 445-457 power while running Port Royal. I might try the 500 watt bios just for fun, but the card is working well enough that I'm not sure I'll bother.
 
ETA: I haven't run PX1 at all, and not sure I'm going to. I've never had great luck with PX1 compared to Afterburner. And I forgot to mention above, I just moved the power slider, I left fans and everything else stock. Driver is 456.98, I'll update to the current driver later, but I assume people have verified that driver version isn't causing their max power issues.

Hi , can this bios work on any 3090?

Hi , can this bios work on any 3090?

Possibly any 3 pin but there might be issues like a HDMI or Displayport port not working. Install at your own risk.

changboy
I just score this on port royal, not verry good :

That's higher than I can get. Highest I've been able to get is 13665 (+1400 mem, +95 clock), so maybe count yourself lucky 
(CPU is a 9900KS at stock 5GHz all core)

Alright so update on power testing. I have a China 20125 board. I ran with just the default bios with max power slider results were:
TBP High- 506.8 Avg- 432
PCIe H-85.5 (had a massive spike there) Avg- 73.6
P1- H-141.4 Avg- 125
P2 H- 148.6 Avg- 128
P3 H- 131.6 Avg- 101
 
Then I flashed the XOC bios and maxed out just the slider (no overclocking of the core or mem).
 
TBP H- 495.5 Avg- 458.5
PCIe H- 81.8 Avg- 76.5
P1 H- 140.8 Avg- 132
P2 H- 143.9 Avg- 135
P3 H- 126.2 Avg- 112
 
So I do not get an average of 500w with the new bios on this China board. My third 8pin is always lagging behind in power draw and is really holding the card back. Not sure if it is due to throttling due to the PCIe slot being slightly over 75 or what. Maybe someone else can explain this more because I am just showing data

Maybe this is not the right place or the right time but I have been messing around with the beta oc bios and the original default oc bios. I am getting more power with the beta oc bios (at default clocks) but the card is still downclocking due to power limit as soon as I hit 450 or higher. If this has already been discussed I apologize. I didn't read all 69 pages of this thread. Would that explain why the performance is actually worse because the bios even though it's rated for 500w now, it still is adjusting clocks and vrel at 450w. Like maybe it down clocks further the higher past the PL?  I have gotten 490w in timespy extreme no overclock just max power slider but as soon as I hit 450 and beyond it starts downclocking and GPU-z also saying power limit has been reached. I am probably way wrong but it seems odd it would be reporting power limit when I have never reached 500w. Another thing I have found is that if I apply any overclock or voltage adjustment in AB it never goes beyond 450w. Only on default settings with just the power target set to 119% does it go above 450w.

yea like 75% or more of people on here can't get 500 w w/XOC bios and are having similar issues. I just sent my card in for RMA they will have a sample, they know this XOC problem is with my card, EVGA has been lurking and monitoring this thread, hopefully when they get my card tomorrow they can look at it more closely. I sort of feel like they don't have a sample of a card that doesn't work with XOC (well they can't just open all their factory sealed merch can they)

just to confirm this is with XOC Bios w/119% power target?I just shipped the card back to them for RMA, they gonna have a sample. Man this plus the other guy who had a Taiwan launch day card that pulled 500w really complicates things.

Yes, the first is default at 107 power slider. The second set is XOC bios with 119 power slider and I didn't get close to 500w. I hit my highest actually lower on the xoc 119% bios (495.5) than I did on the default 107 power limit ones (506.8).

strange times indeed. add an easy OC of 100 to core and 400 to mem and lets see if XOC can draw 500w consistent in msi kombuster 64 GL-furmark- donut high res fullscreen. your card reaches 500w peak though, mine never got close i mean NEVER under any circumstance could I push it to peak past 470-480. your card has hit the mark if only briefly, perhaps it's not under enough load to sustain that peak.

So sounding like having a Chinese card doesn't guarantee a 500W average.

[/quote/]
this many be true. we are still gathering data on it before any kind of conclusion can be made, but my taiwanese card has never since I've owned it hit a 500w draw one time ever. day 1 for him, and he said he didn't oc core or mem yet....well that's how he's gonna make it hit his peak and stay there...OC the living heck out of it and we may find out yet that he can.

what do you guys get on Blueroom score for VR?

So it looks like the 8 pins should be all drawing 140 watts before relegating to the PCIE slot.
But for some reason, the third 8 pin isn't pulling its weight in power.  140 * 3 + 75 is exactly 500 watts, which is probably how this bios is supposed to have its power draw partitioned.
But if the stock bios doesn't draw from the three 8 pins in an even way, then you're going to have problems.
 
The big question you guys need to figure out is this:

Is the 140 watt 8 pin limit signaling a power limit rail?
Or is the 75W PCIE slot limit signaling a power limit rail?
You guys need to realize there are multiple rails that determine power limits. 
The only one the TDP handles is Total Board Power, which is equal to all 8 pins + Slot power.
 
I know on the 3090 FE card, the 8 pin power caps out at either 170W or 174W, but I do not know if this is affected by TDP--it probably is *NOT*.  PCIE Slot can go up to 85 (Unconfirmed).
GPU Chip power caps out at 300W.
 
There's also individual 8 pin power rails, Slot Power rail, GPU Chip Power rail, MVDDC Power rail, PWR_SRC Power rail, and possibly one other.
 
The one thing I haven't seen *ANYONE* here post:

What is the difference between your TDP% and your TDP Normalized %?  GPU-Z does not show this.  HWinfo64 DOES show this.
 
If TDP Normalized is appearing much higher than your TDP% and your TDP% is appearing much lower than the "cap" you set , when you hit the power limit, it means an internal rail is throttling you.
