I used this guide to flash my BIOS: http://www.overclock.net/t/1521334/official-nvflash-with-certificate-checks-bypassed-for-gtx-950-960-970-980-980ti-titan-x
I just have my Power Limit and Temp Limit linked so they both slide to their max. Probably not necessary to max out your Temp Limit with WC but I do it anyway. Flashing your video board's BIOS is always risky. You can 'brick' your board if there is a power failure during the process. I wouldn't recommend flashing your BIOS during a thunderstorm for instance but you have no control over whether a drunk driver is going to crash his car into your local power substation or a power pole either. It took me several tries to get it right.

My Gigabyte WF3 has a dual bios so there's nothing I've to worry about.
Nice guidelines, gonna read them some more. smile.gif
So, what do you suggest me; to mod my own bios or to flash a (techpowerup) 980 G1 Gaming one?
I'd only need to get to those (G1) a bit higher oc freqs and boost as well as the power limit.
Maybe I'd better mod mine instead, wouldn't I?

I have to agree that having a dual BIOS is really handy to recover a botched BIOS flash. Many companies place a higher performance BIOS in the second BIOS chip. EVGA does this with their dual-BIOS boards. The only way to check is to power down your PC and flip the switch to the second BIOS to see if you get a higher Power Limit.

Do your own. It will 100% work if you use your own.
Here's how to mod the BIOS:
http://www.overclock.net/t/1522651/disable-boost-and-bake-in-max-game-stable-clocks-for-maxwell

And here are the tools:
http://www.overclock.net/t/1521334/official-nvflash-with-certificate-checks-bypassed-for-gtx-950-960-970-980-980ti-titan-x

I'll make this easy.

1. Plug in a flash drive and determine the letter. (We'll use F: for this guide)
2 Extract ALL of the files from that download into the ROOT of your flashdrive (not in a folder).
3. Use GPUz to extract your BIOS and follow the guide on how to modify it.
4. Save the BIOS as what ever you like inside the root of the flash drive. I'll use 980mod.rom

So my flash drive (F:) has the nvflash stuff and your modded bios (named 980mod.rom) in it.


5. DISABLE YOUR VGA DRIVER!

6. Open command as admin.

Type:
f: (hit enter)
nvflash -6 980mod.rom (hit enter)


You will be prompted to hit "Y" 2x.
Restart your machine and enable your driver (which will restart your machine one more time)

I bet it's a fan profile. Mine was...thanks EVGA. rolleyes.gif

LOL, ymmv with EVGA. I helped someone who had a nice increase using BIOS B while others had no change at all.

What's crazy is that they even put a dual bios switch on a voltage locked card...

It's not working exactly that way, the Gigabyte 980 WF3 (and the 970 - 980 G1 also) uses two bioses without any selector switch, they simply are connected to the two main DVI connectors:



Now, I'm connected via dp, the first one (C connection) which I assume is using the first bios like the DVI-I port. However I also tried with the second dp port (D2 connections) and got the same bios and power limit max (111%). I just can't use any of the dvi's since my monitor lacks of the dvi port.

Thanks!
Then maybe I should play with the oc (and the needed overvolt) some more in order to get those "fixed" max clocks and voltages (since they're not going to be played with any more once the new baked bios is out and working).
Let's suppose I don't want to get up to that point (for now) and I'd only like to have the same boost voltage but with the (slightly) overclocked freqs (those of the G1 Gaming) and with the power limit increased to let's say a max of 125% (in software) in order to, on one hand use the vanilla (G1 Gaming OC) default clocks with the less demanding games and on the other hand can still play with the software oc (at least for some more time) like the afterburner (just installed) and could even increase the vcore and the pl (for the power limit I have to study some more that guide in order to, why not, increase some more even the pcie and the two 8pin rails if necessary) smile.gif

Flash a G1 bios to the side you don't use.
The traces are the same.

Could be a solution to start, my WF3 is a F50 bios (GIGABYTE uses different bios numbers for different series, I don't really know what they means) so I've found two G1, F50 bioses:

https://www.techpowerup.com/vgabios/169265/gigabyte-gtx980-4096-141023.html
https://www.techpowerup.com/vgabios/167661/gigabyte-gtx980-4096-141023-1.html

I think I'll take one casually biggrin.gif

And this way I should even discover if there really is the second bios on the last dp either, hope is not the same one

Btw, I've just finished a series of loop & benchmarks (Heaven 4 and Valley Extreme HD, FireStrike) to test my memory at 8000, it seems to be working just fine.
I had some doubts (it has the hynix instead of samsung) about clocking that high but maybe it can do even more, niiiiiiice! cool.gif
