Bump.

https://www.overclock.net/threads/official-nvidia-rtx-3080-owners-club.1753932/page-29

Looks like someone flashed a 3080 FTW3 bios onto a 2x8-pin Palit card and it ran at 400w.  So, we'll have to see.  No word on a 3080 Strix bios yet.

Just flashed me a 480W VBIOS on my 3090 FTW3 - testing now (ICX sensors all still show)

^SEE MY EDITED POST.  

It flashed with the -6 flag. Trying it now (had to reboot for driver reinstall after the reboot for flashing)

GPU-Z shows a 480W limit now instead of 450, but even at full stock (power limit slider and fans maxed) I still get the power limit flag in port Royal.

-- 19,680 GPU in Time Spy.

Asus Strix OC vBIOS just made the FTW3 3080 the card to get IMO. With the Asus vBIOS it is basically shunt modding itself and hugely under reporting power draw and the card holds crazy high boost now. I just managed to score the #1 spot in the US with this vBIOS on my FTW3 Ultra. Reported power draw under max overclock and max fans was around 330w. It's under reporting but the card performance is still scaling and the clocks are boosting to over 2100Mhz and holding near 2100Mhz the entire TimeSpy run. Not quite sure of how or why it's doing this yet, but its working and working well [image]data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7[/image].

Fans run at same 3000rpm max so no issues there. One DP was deactivated, but haven't tried HDMI. Works for me as I use 2 DP ports for my monitors and they work.

Asus Strix OC 3080 vBIOS shared by a nice new owner over at reddit. They did us a solid!

As per the title, has anyone tried it yet?  From the 3080 strix, over on overclock.net...........?  Sounds like it is working really well.
 
Though I'd strongly prefer if EVGA would officially release a higher power 3080 FTW3 bios, 450w or greater, especially with hybrids and waterblocks coming out.
 
EDIT:  Get it HERE...

I'll certainly consider it when mine eventually arrives, especially since the whole 400/420w issue that has yet to be addressed.. Realistically I want 440-450 anyway lol, the fan control doesn't bother me because I'll be blocking it as soon as EK make them available.

I placed my order largely based on a 420w power limit and watercooling support, and now one of those things have been cut back.

I'm curious why they capped it there and what components they decided was a limiting factor.. feels fairly low for a flagship model.

If you want me to measure the pcie cables lemme know, I've got a decently accurate amp clamp.
You'll have to wait though, us Australians seem to have gotten a half dozen cards to share; ordered 15 minutes after launch and the closest I've got to an ETA is "Early November"

Jacob said hes looking at the whole 400w instead 420w, hopefully the issue a bios update that brings it up to 420w that should be. So far they fumbled it and shipped all the cards with a 400w max bios. There is plenty of proof in the power limit thread.

Guess we'll see.. :)
Reading that I couldn't help but have flashbacks of childhood asking my parents for something
"We'll see" "I'll think about it" "We'll look into it" nearly always meant "No" lol.
 
But given it's out in the public, suppose they have to do something.. Just curious why they arrived at that limit.

Saw this over on overclock.net:
 

Holy sweet baby jesus, this BIOS is NUTS. I'm not going to turn my AC on just to run some benches right now, but playing Metro Exodus on the stock FTW3 Bios, I was pegging 400w with transient 420-430w spikes the entire time (3840x1600 / Extreme settings / RT max / DLSS off). With this BIOS, it's reporting 320w max. LOL. I must be pulling over 480w, there's no way. The only issue with this, is that temps are much higher. I went from 74-75c max to 82c at one point. The clock speed, even at 82c, was 2010-2025. Clocks are so much more steady now rather than the bouncy-castle rollercoaster that it was before due to the power limit getting slammed.

 
Would be great if someone could get a more definitive test/assessment of exactly what this bios is doing with power draw.  Most UPS's have a somewhat accurate power meter on board, can someone check overall system draw with a benchmark that hits power limit vs. the stock bios?
 
Personally I still think there's something about the ASUS bios that just makes it clock better at lower vcore.

Just a bit more info - did a little further testing.  Turning up the power limit didn't do anything for me.
 
I managed to get a system draw up to ~612w.  Maybe GPU power ~450w?  Couldn't get stable at +100 core and temps were hitting mid 70s and dropping the frequency anyhow.  Benchmarks CTD trying to hold 2050 mhz.  So pretty poor bin compared to what others have posted.  OFC I'm on air...but I have my case fans cranked (o11D with bottom intake blowing at GPU) along with the GPU fans cranked.  Disappointed to see my card compared to some of the silicon lottery winners.  Was hoping for more from EVGA with their flagship card.  Would be curious to see how many ASUS cards are as restricted or if their binning was better for their Strix.
 
Will probably swap back to EVGA bios for now and see what they do with the power limits.  Perhaps they set it to 400w because they were not binning chips as tight as originally planned due to lack of quantities and wanting to get their higher priced parts out for the margins...
 
Highest Port Royal was 12,300. https://www.3dmark.com/pr/395673 Same settings CTD on Time Spy Extreme (temps started climbing).

Just to be clear, when you say "you can see a higher draw from my PSU on the Asus bios (at 100% power)", do you mean 100% on the Afterburner power slider?  

kevinc313
People have reported good results with a lighter load such as normal Timespy 1440P, so maybe try that and your card will be able to hit higher clocks / voltages?  Here's a video another member posted where he runs Heaven with high clock and high voltages, with a reported wattage ~275w (=368w x 75%), but he's probably at least over 400w (ftw3+strix bios).

On my 2080 Ti, I can pass normal Timespy 45mhz higher than Port Royal.

So to take this a bit further, here's the log of a MSI gaming trio with the Strix bios, from earlier:
 
https://fotos.subefotos.com/f31635bea6fd8ab2e8aae9ffd914d2b0o.jpg
 
If he's getting a similar 40% under report of power (no guarantee he is, different card), that means he's pushing about 600w, to get that peak of 2190mhz, which is pretty crazy.  I bet he is also getting pretty high vcore, either just by getting high up the curve with a light load or by locking voltage.
 
TeslaDev - you might want to try locking in voltage at 1.093v with the power maxed out and see how high the card can clock on a lighter load like Heaven, before deciding you lost the lottery.

Wow, yeah, that's pretty crazy.  Definitely pushing some higher wattage than indicated.  
 
I can't get Afterburner to see my voltage.  I've tried all the various settings (3rd party, reference, etc.).  It won't display.  I just installed precision and it sees it, HWInfo64, and GPU-Z all see it fine...TBH, first time I'm tried afterburner...normally just stick with Precision.  Nvm. I'm a dummy. Got it going - will check into this more.
 

TeslaDev
Alrighty - so I tested the waters with some interesting results for sure.  Plots at bottom.
 
The Asus bios does flash easily enough.
 
The power reading is definitely off, reading much lower than actual.  From looking at the plot, you can see a higher draw from my PSU on the Asus bios (at 100% power).  About 15 watts higher during first test, 40 watts higher during 2nd test.  Using the EVGA runs you can extrapolate my system power by subtracting the GPU power from the total power and get ~112 watts in first test and 131 watts in 2nd test.  If I subtract those values from the total power in the ASUS bios runs, I get an estimated GPU power of ~412 watts and ~432 watts in 1st test and 2nd test, respectively.  Rough estimates it looks like given very limited number of runs.
 
I only ran a +50mHz OC on the ASUS bios to add a tad of stress and was getting pwr limit indication in HWInfo64, but plenty of headroom here yet and I'm not sure what is accurate and what is not. However, this runs MUCH more stable with the added power, which you can see from my frequency plot. It held pretty steady.
 
Temps were interesting.  The fan controls did work in afterburner.  I did my best to recreate the same fan curve in afterburner as I had in precision xoc, and I think I was pretty successful.  The cooling wasn't too bad, only a few degrees up on the ASUS bios.

Easily beating my very best runs from the EVGA OC Bios. 12128 in PR against 11857 (which I struggled to get).  Might play with it a bit more later to give it higher OC and see how well it holds and how much it draws.
