How to BIOS Flash a ASUS 980 Ti Matix Platinum?

[EarthDog]

Ok... this thing is a bit limited at stock once you overclock. To that end, I wanted to make another BIOS for it. I didn't want to change voltages or anything (for the moment), but just wanted to raise the 100% wattage, and the 110% wattage (power limit).

I have the latest nvflash that bypasses certs etc (not that I should need it because its the same card). I have Maxwell II BIOS Tweaker 1.36.

THings I have done:"

*Saved a copy of the stock BIOS.
*Modified the BIOS as follows...(modded version on the left, stock on right)


Saved it as GM200mod.rom and tried to flash...



It just sat there for 10 mins... What easy thing did i miss???

I was following these instructions... http://www.overclock.net/t/1558645/official-nvidia-gtx-980-ti-owners-club



Any help would be appreciated... its been a while since i tried this!!

Well, it worked. I am not sure why it hung the first time I did it, but, it worked when I tried the process again.

With the settings seen in the picture, I am now hitting around 90% with the Power Limit slider at 100 when fully overclocked. I need to push on this a bit harder and solder the LN2 pads to get even MOAR.

I will adjust this thread at some point and make it a HOW TO.

Next question is when you're putting a pot on it?

I'm surprised that card doesn't have a switch for LN2 bios or similar?
If you connect the pads you won't have to worry about limits though. That's how the 290x was any way.

That's how it works, however, I do not have anything in the house to connect the pads. No conductive ink pen, nor tape, and using a #2 pencil did not work. I have ordered the pen.

@ Mandrake - I dont have my fat GPU pot anymore, so... never.

Time for a Rodeo Clown set up and a radiator out the window.

I soldered mine, easy peasy

If you're using a bios that you took from your card, and changed the settings in it, I don't think you need the "-6" there. That is, I've never used it. Just -- nvflash 1275GM204.rom

Don't use the bios files on the first page....they're hot garbage, but...the process is talked about in detail.

Thanks Vell!

I modified its own BIOS and dumped it back on there. Not good for voltage increase over stock, but lets me stretch its legs a bit on the meager (for benching purposes) voltage I have to change (50mv).

I'm not really familiar with the limitations on the GM200s...I'm more well versed in the GM204s. I know the restrictions EVGA put on the GM204s in the bios could be modified a bit, but.....there's still some speculation as to how much. I've tried several different settings in my own bios, as the reporting software only shows 1.275v. With anything over that, I show no increased stability at my peak clock rates, no difference in temps...at all, and no change in the power limit / TDP usage. Seems to me, that they're locked down at the VRM to 1.275v. The MSI and Gigabyte cards seem to still get gains all the way up to 1.312v.

Not sure if that pertains at all to the GM200, but.....something to ponder.

I am rather curious though, as to how one may go about bypassing the restrictions at the VRM, and getting more volts out of it? Hardware mods? I'm all ears. = )

 

[EarthDog]

Any thoughts on what to change to get the voltage up? I know I can unlock the LN2 BIOS, but for curiosity sake.

I am likely still limited around 1.275, but I can't get this thing to budge past 1.21v with its 50mv increase.

 

[Johan45]

E_D you could have a look here at X_A's LN2 post near the bottom is a link to GPUTweak. Sometimes "their" versions have a little more headroom. Might be worth a try. My gut feeling is you're going to have to short the pad to get the extra volts. Just remember that the new die isn't too voltage tolerant without chilling it. They like low temps better than high volts

 

[EarthDog]

Just the unlock seems to do it and GPU Tweak II. I was finally able to get past 1.21v. Gives me up to 1.8v.

Let's see what she can do on air...It was about average to slightly above at 1.21v 1533 MHz actual boost.

 

[Johan45]

Good luck E_D, that BIOS should have some improved memory tables in it if you're interested in a bit higher mem clocks

 

[EarthDog]

Yeah, it will be a work in progress... I have cold air in place, just need the time now... with CES this week................grrrrrrrrrrrrrrrrrrrrrrr.

 

[Johan45]

Are you going?

 

[EarthDog]

Yep!

Mdcomp and I.

I've often thought of going as a vacation for the wife and I. I like electronics and she loves casinos. Ha ha
Have fun man.
