........Apparently the same chip is used on some ASUS motherboards, if I can locate one I will be in contact .
That sounds promising, even I have a "dead" ASUS motherboard (failed BIOS update, no boot, otherwise all OK), let me think what model it is... I think P5K PRO or something like that.
The chip the card uses is a PEX8747 (see: http://www.plxtech.com/products/expresslane/pex8747). Some boards I read somewhere are using it to expand the number of PCIe slots on it.
Edit: The ASUS P8Z77-V Premium uses it and it seems it is not using a heatsync! Perhaps I have misdiagnosed the fault, I will have another go tomorrow and check things on it to see if I missed anything obvious.
It should be noted that this mod was originally performed not to get a high performance Quadro or Telsa card, it was done to unlock additional features such as Mosaic support which does indeed work.
Hey I know this is off topic so please don't flame.
I was able to, by the grace of god and not my soldering skills, change my 680 into a GRID K2 (mini). If anyone is doing this for virtualization reasons check this VMware thread out for help. I can now report that I am sharing my 680 among multiple Virtual Machines.

Please everyone else donate something if this has helped you out!

Been using mine with Windows Server 2012's Hyper-V RemoteFX. It's pretty cool being able to remote desktop in to a virtual machine and then play GTA IV on a 2007 Macbook Pro lol
I've been researching soft straps for the past few days and there's a way to change the Device ID without soldering.
Problem is that I could not find full information about the strap bits and so what I could piece together so far is that you can change the last two digits to a certain extent.
If you have a 0x1180 (GTX 680) you can go up to 0x119F (range: 1180-119F), basically you can change bits 0-4.
I do not know if/where the bit 5 is to take it above 9F into As and Bs for the 3rd character. I am not sure if that bit is even present in the soft straps but seeing there's a resistor for it, I'm hoping it must be somewhere in there...
Anyone with some insight into soft straps, bit 5 and beyond please post.
This is pretty sweet! I will have to have a go at it as I hate rebooting into windows for the odd game. I had never heard of the GRID K2 nor what it could do until members mentioned it in this thread.

What the GRID K2 cards are essentially aimed at is the ability for a person to connect from a system on a say an ultrabook, where hardware is not capable of very high end graphics, to a server, and supply a much higher performance than the local hardware is capable of by itself. You can connect to a virtual machine being hosted on a server with a GRID K2 and use the discrete graphics card in things such as say Solidworks. Where I work we have our servers for our engineering department with GRID K2 cards, we used to use Dell desktops/Laptops with high end quadro cards, but now instead of dropping 3 - 4K on a laptop that might fail after a year or two, everyone gets a cheapo laptop configured to use a virtual machine. This works very well on our gigabit ethernet network too.

So does that mean that multiple users can share the same video card across multiple VMs? or just a single VM? And how well does it work with games, etc? It would be nice to be able to share my high end card out for my daughter to use instead of having to buy her a high end card also.
Hi everyone, new to this forum so go easy on me !!
Great work on the mods been done on the GK104 chip - I want to have a look at my GK110 chip now .. might be I should wait until the K6000 card for the device ID + drivers but might settle to try for a K20X
I have attached some pictures of the EVGA Titan card - thinking of looking at the resistors near what I think is the eeprom - am I on the right track ?
Did you actually test this or is it based on the soft-strap information documented here:
https://github.com/pathscale/envytools/blob/master/hwdocs/pstraps.txt
I tried this first and had no success, Linux would ignore them, and we know that in previous generations that the NVidia driver would compare the soft to the hard straps and if they differed enabled 'unstable code' that was designed to cause random hardware faults.

I did test on a smaller card (8600GT) as a proof of concept. It is a very delicate operation because setting up wrong straps will hose the card (I know - I did it).
To recover you need to short CE# and Vss pins on the card's EEPROM during boot, then unshort them before running nvflash, to recover from the bad flash.
I am going to conduct a few more tests just to be sure.
The references I used to collect the needed information were the link you posted above; this thread: https://devtalk.nvidia.com/default/topic/489965/cuda-programming-and-performance/gtx480-to-c2050-hack-or-unlocking-tcc-mode-on-geforce/1 and couple of other places for random other details. I've also looked at dozens of ROMs comparing their soft strap configurations and what not.
I can confirm that changing the software straps does not change the device ID in the 6 series.

The fellow from that NVidia forum post modded a 480 and 580 with this process. I wonder if NVidia caught up to this in 6xx...
That is what I have said, they did, it does not work in the 6 series, I spent many hours testing this method before restoring to hardware hacking.

Humbug....well, Fedex is coming today with my 0402 resistors and some larger EEPROMs.
Why the larger EEPROM? are you going to try and install the quadro/tesla bios?
