But in this case. I think I've atleast cracked the easy bit. On this page. There's a complete list of the GPU's that Nvidia use.

If you scroll down to the bottom of that page you'll see the latest GPUs and probably recognize some of the values out to the left in the field. I see GK104, GM107 and the monster GK110 with and without B.

Now, the furthest to left you see something called a core pciid and a value below that. That value is the different variations of the card.

For example if you look at the GK104 row, you see the core pciid is 118X*.

As we all know the [NVE4] GK104 comes in many different types and variations, you'll find an almost up2date list here.

The specific id for those different cards are as following;

GTX670: 0x1189
GTX680: 0x1180
GTX760: 0x1187
GTX770: 0x1184

"Hence the 118X" from the envytools site, the GK104 comes, as I wrote earlier in many types, some listed above..

I found theese values in the "ListDevices.txt" located in C:\NVIDIA\DisplayDriver\335.23\Win8_WinVista_Win7_64\International on your computer it might differ since you might not have installed it in the same volume as I did, but most likely, you have done that.


Now, the tricky part. I've got a Gigabyte GTX680 WF3 rev1 PCB in my GTX760 WF3 rev1 - this means that my PCB fully supports the GTX680 circuit. Meaning that if I could find a way to unlock the GPU. I could have myself some extremely nice performance boost.

So I need to get the 0x1180 core pciid instead of the 0x1187 core pciid onto my card.

So how would I do that?

I'd think it's a root related thing you have to do. Here's a quote from the envytools page:
Warning: Spoiler! (Click to show)

This PEXTDEV that Nvidia calls it is probably the key to unlock stuff. And that program is probably extremely secure. So we need something in the style of it in order to unlock the cards.

I believe this apply to all the newer cards, such as the 780/780ti/760/770/660/670/680 n' so on.

What do you guys think, do you think I'm on to something?

Well according to http://www.eevblog.com/forum/chat/hacking-nvidia-cards-into-their-professional-counterparts/ it's ALL HARDWARE Modding, the second pic on this page shows you the straps on the GTX 690. I did see how he explained to figure out these straps although it made no sense to me. He said that he attached a voltmeter and then checked to see if it was a 3.3V line and if it was he knew that there were straps there as long as the path went straight to the GPU, not sure about it all but it sounds pretty accurate.

As I understood it, the strap that ... strangles the GPU has to be removed hardware wise, that would "unlock" the cores. After that a pciid change would be suitable, and then lastly a BIOS rom would have to be placed onto the card.

Feels like I'm of to buy some cheap 760 to do some hwmodding on right now..

You know, I would love it if you could try this, at first you ONLY need to find the straps and remove them, the PCIID will change on it's own since there are no straps saying "No you can't be this graphics card, you need to act like this instead" It's basically like a computer trying to install a computer OS, you enter your key and it basically says "Okay now I have to install this edition, not the other one". The BIOS makes no difference as you test, it will still be recognized as a 680.

Brother I wish you good luck in your mission, if you can figure this out and spread it to the community I'm sure you'd be loved forever! +REP to you!

Thanks mate, at first I'll try to see if I can get my hands on a GTX 680 WF3 rev1 and just compare that PCB to my GTX 760 WF3 rev1 and see where they differ apart. Since it's "only" a few straps.
The hard part will be to locate them.

Thanks man, I'll keep you guys updated with pics when I get my hands on a 680WF3 rev1.

Wish me luck.

Heaven 3.0 crashes with this 'new' OC so unfortunatelly this is far from stable . But than again I've managed to get to get around 1250MHz which is still 30-ish MHz increase, so far no crashes with heaven 3.0.

Funny thing is new heaven 4.0 crashes on start before even starting loops or benchmark even if my card is on default clocks, I'm on new beta drivers, anyone having this issue? rolleyes.gif

So heaven is hell with optimization smile.gif there gotta be some coding issues:
min 7 fps WTH!!!
And only 5% on core OC or crash...
But normal optimized app like valley Oc 11% and min frame is great (more important then peak fps).

Please help me, I have GTX 760 hawk and switch to LN2 bios, but my vga just have 980 mhz core clock. Problem second when I change core voltage to +100, I see afterburner monitor the core voltage just stack at default (1.2voltage), What have to RMA or any other ways ??
