Nice! There was a guy here that analysed the FE one, will be interesting to see how the power limit compares to the FE.

In theory this could be flashed to a card right? i.e. it's already signed?

I successfully flashed the Strix BIOS to my 1080 TI FE.

I'm getting 2100 core at 1.075v 6132 memory, Power Limit never goes over 111% an entire Heaven run, and as you can see by my GPU-Z file it never throttled or lowered core or voltages once the entire Heaven run, no shunt mod.

GPU-ZSensorLog.txt 35k .txt file

Here's how I did it biggrin.gif

nvflash_5.353.0.zip 3031k .zip file

1080ti_strix.zip 154k .zip file

Unzip NVFlash and the Strix bios to a folder.

Disable your video card in Control Panel in Device Manager.

Run an admin command prompt and cd to the folder you made.

Do in command prompt:

nvflash64 --protectoff.

Then do:

nvflash64 --save filename.rom

to backup original bios.


nvflash64 -6 biosfilename.rom



Reboot, if the card is not enabled in Device Manager, enable it, reboot again. Good idea to reinstall Nvidia driver, reboot last time, done.

For more than one card.

nvflash64 --list

nvflash64 -6 --index=0 BIOSfilename.rom

nvflash64 -6 --index=1 BIOSfilename.rom

Choose yes when asked to override mismatched IDs.

Also my card now downclocks a little higher @ 240mhz at idle instead of 138mhz like it did before.

Finally, now my voltage slider in AB is greyed out again.

Count me in as well guys. EVGA Founder's Edition, but might get the Poseidon when it releases ;-)

Took the pictures a little artistically biggrin.gif

Use the WildCards.zip one.

me and a few people was the first to flash the STRIX bios to the 1080 FE

what we found out was we could get higher boost... but performance was not on par of the FE at lower clocks

I think the STRIX shows higher clocks but is weaker.. test it out.. put 2k on the FE bios run a benchmack and then go run STRIX bios at 2k and report back wink.gif

Well... Now that I got voltage slider back I did some testing in Heaven and my max TDP is 108.5% vs before with the stock FE bios I'd see my TDP shoot as high as 138% So I'll look at this as basically a poor/conservative man's shunt mod. thumb.gif

Be careful with this one - there is a genuine risk of overloading a couple of the VRM phases on the FE card by using the Strix BIOS as it has 2x 8-pin connectors and the current split between the phases is going to be very different.

In the FE BIOS the allowable limits with the adjustment slider maxed are:

78W from the PCIe slot, 99W from the 6-pin PCIe connector, and 175W from the 8-pin PCIe connector.

It's tough to tell how they partitioned the VRMs on the FE since I don't have one in hand, but if it were me, I'd probably power one phase from the PCIe slot, two from the 6-pin, and 4 from the 8-pin PCIe connectors.

However, the Strix 1080Ti (and most of the aftermarket cards) have 2x 8-pin PCIe connectors, and allows 78w from the PCIe slot and 175w from each of the two PCIe connectors.

If the FE card did partition the VRMs such that there's double the phases assigned the 8-pin versus the 6-pin connector, then using the Strix 1080Ti BIOS might mean that you're underloading the 4 phases assigned to the 8-pin PCIe connector and heavily overloading the (2?) phases assigned to the 6-pin.

It might be worth pulling the backplate and using an infrared temp gun and seeing if any of the VRM MOSFETS are at a very different temperature versus the others. Out of the box with the stock BIOS they should be pretty well balanced.

forget what its reading tongue.gif

do some performance tests!

put it at 2kMHz run valley 3 times take the average, do the same for the STRIX bios

Not too much point really aside from stability due to not hitting the TDP wall. My OC is the same, no changes with running the strix bios.
