Edit:
For those that are just spewing trash on HaD comments without doing a little research... the parts are identical, changing the Device ID just makes the binary blob advertise the additional features to the system, and enables them. It does NOT affect the clock speeds, and will not make the card faster for general day to day work unless you are using the specialised software that takes advantage of these 'professional' features. Changing the ID does not affect the clock speeds as they are configured by the BIOS which we are not touching.
And stock, the GTX690 is clocked FASTER then the K5000 and the Tesla K10, so you are getting a faster card in comparison, not making the GTX690 faster.
I repeat, this does NOT make your GTX 6XX card faster, nor does it make it slower.
Tesla K10 to Grid K2 successful
I had to mod two resistors for GPU0 and GPU1
What I did was removed 25k and installed 40k to make it perfect match
Does GTX 690 also require modifying two resistors?
I also updated all the vbios to K2 so it looks like K2 now (updated PLX as well)
I will test vgpu functions in few days.
Really thanks for the efforts of gnif and verybigbadboy
However, since I have a EVGA GTX670 with the same PCB layout like GTX660Ti
So I need to find the modification by myself and here is the result.
For the 4th digit, as everyone already knows, it is right on the position of resistor 1 and 2.
Depend on which card you have and you can remove resistor 1 and change it to tesla(40K), grid k2(40K) or Quadro(15K) on resistor 2.
For the 3rd digit, it is the tricky part.
As the low byte on the top side of the PCB with resistor 4.
You don't need to do anything for Tesla K10.
However, if you need to change it to a Quadro K5000 or Grid K2
You need to remove resistor 4 and install resistor 3 "MANUALLY" since no place for resistor 3 any more in the PCB of GTX670 and GTX660Ti
As you can see in my attached bottom side photo for the "rework".
You need to connect to EEPROM pin 6 with a 20K Ohm and pull up to VCC.
My rework is quite ugly but it works fine!
Please be careful and take your own risk for modifying your card!!

Anyone has bios dump of K2?
The one I used from HP is missing InfoROM and it looks like causing compatibility issue on certain system.

can you give me a grid k2 rom,thanks very much, i look for it for a long time.
one 25k resistor on each GPU right?
I found one on each GPU but not two

PMed you a link to it
i sucessed k2=>k10 after change 2 resistors.
on dell r820, it works ok, but only with vsga, can not work with vGpu。
i think it may be due to the rom, so flashed with k2 rom(with override bord id), then system can not boot up, block by pcie scan.
i flashed back to k10 rom with other pc now.
Any one knows who to use vGPU , just like the real k2.
Just noticed I didnt reply to your pm, sent you links to both bumps
