Just dropping this here for OCUK as it's quite a breakthrough for BIOS flashing for many people stuck on FE cards/with voltage limits. Most of us will have a good choice of BIOS to flash for our cards to eek out some more power, others are far more restricted depending on the model of card purchased.

As I just posted in the 4080 topic here, I went straight to testing the 1000w 4080 BIOS I previously couldn't flash due to a board ID mismatch as the 4080 has a few SKU's. Not only did it flash fine, the results are a bit terrifying lol

GALAX RTX 4080 VBIOS

16 GB GDDR6X, 2205 MHz GPU, 1400 MHz Memory

www.techpowerup.com

673w of power draw on a 4080 at 1.125v lol (this BIOS goes up to 1.195v )

Obviously I don't recommend going right to a LAB BIOS with power limits like 1000w (especially not on air cooling ~ Or even water to be fair, look at my hotspot temp with furmark lol!), but if you have a FE card or a 4xxx series that came voltage limited (IIRC some cards topped out around 1.07v whereas 1.1v~1.11v has been quite common in others) this could be a chance to eek out some more power.

Preliminary tests show as long as you don't do something stupid then flashing a BIOS made for your model of card (4080 -> 4080) is going to work fine, but ymmv and those without a dual BIOS card might be best waiting for even more data feedback.

106c, geez dude be careful there is a reason 1000w bios is kept for LN2

It's Furmark and only for a minute lol. It basically just pulls as much power as it can.

Just beat my previous PR record by almost 100 points https://www.3dmark.com/3dm/98787408 Which is nothing really, but it's fun to mess about with.

The flashing tool itself will be much more useful for anyone on an FE card with low power limits/voltage caps below 1.1v.

Now people really will be able
To melt their gpu connectors without
Having to buy a 4090

I scored 19 918 in Port Royal

AMD Ryzen 9 5950X, NVIDIA GeForce RTX 4080 x 1, 32768 MB, 64-bit Windows 11}

www.3dmark.com

There we go, tuned the voltage in a bit better.

Hotspot is at least manageable now. Still might tear this Gigabyte factory waterblock down one day and repaste it. My deltas between core and hotspot are fine around 300~400w, but once I go higher it increases. 514w pulled above running Port Royal.

This will work on a 2080ti right?
Did read the post
But got caught up with the two guys
Having a bit of a lovers tiff
And missed the technical bits lol

Yeah it will do, just make sure you're obviously flashing 2080Ti BIOS, don't try and turn your 2080Ti into a 3080 or something

Lol
Awwww was hoping to end up
With a 11gb rtx4090
Seriously though just want a little more voltage
Nothing extreme
Not as brave (crazy?) As you were lol

I had a 2080Ti on water, I had it at 1.1v IIRC but that was just from normal BIOS flashing.

Have you got a FE or something? I remember I could have benefited from more power as well with that card just because I cooled it so easily on water.

So yeah I'd check techpowerup for the best 2080Ti bios revisions. There's probably a LAB BIOS for it as well with the 1000w limit lol.

No got a kfa2
Wasn't my choice there's a long story
As to why ended up with that make
It's ok
But it's got about the lowest
Voltage you get on 2080Ti

 

[Dg834man]

Your gpu always had a 30 degree delta or just in that test with the new bios?

Just Furmark. 515w delta drops to around 20 degrees as above in Port Royal. Gaming around 300~400w its more like 15 degrees.

Has it got a dual BIOS?

Good question actually
Don't remember lol
Looking at some bios on techpowerup
The kfa2 hasn't got the lowest power target
So may be when gpuz says reason
Power limit
it may be lack of voltage rather than
actually hitting the maximum watts
Any easy way to know
Which bios on there allows best voltage adjustment ?

Been a while since looked at this stuff
So will obviously check it all
In gpuz
Before trying anything with it

Edited
Google says dual bios on kfa2 hof version
Looks like my 1 click oc version doesn't have it

1.1 or 1.11v tends to be a retail BIOS limit. It seems to go above that it's into the GALAX HOF bios which are the big boys for LN2 overclocking lol.

You'd need to check GPU-Z for your card firstly to see what its power limit is. Then are you on air cooling or water? Temps will ramp up with more wattage/voltage, those are the laws lol.

It might even be possible there is a BIOS you can flash with the normal nvflash tool? Have you tried previously? This tool is for those struggling with board ID mismatch errors.

Think I tried
Back when first got it
Don't remember the error message
Could have been mismatch
Think I only tried one bios

On custom watercooling
So temps not a worry
Not intending to use a HOF 450w on it lol
It's only 2 x 8 pin

Yeah there is a good chance you won't need this tool but other nvflash just using -6 command. When you have time drop your card version and its power limit and I'll lookup some BIOS for you to try on techpowerup.

Thanks mate
Pretty positive I didn't use -6 command
Will look in gpuz later
Once am on the pc

I wonder if Nvidia will try to clamp down on this through drivers or something.

 

[Mcnumpty2323]

So had a play around with my 2080ti
Power goes to 108%
Does have an effect when change from 100%
But unlocking the voltage slider and changing voltage
Has no effect
Won't go past 1.043v annoyingly
Board power hits 280w at 108%

Overclocked core to 2050mhz
Overclocked vram shows in gpuz was 1750mhz now 2000mhz
Or 7000 now 8000 in xtreme tuner
Probably a little bit left to go but I just did
A very quick overclock

Gpuz perf cap is for power and vrel

So it does overclock at least
So question is
Will flashing another bios really make much difference?
If that voltage would actually go to even 1.1v
Then would probably be happy with it as is

If so
Not done this in ages
Better to flash in windows?
Or in dos?
