It's hard not to get excited over modding a GTX to a Quadro or K series pro card. However, is there any particular reference or non-reference GTX 6 series that can be modded 100%? I am willing to take the risk if it's not too difficult.
Actually, I have the GTX670-DC2-4GD5 non reference, has anyone attempted it on this card and had any luck? Please let us know.
You'll find that even most non-reference GTX670/GTX680 cards only differ minimally from the reference design, and the strap resistors are in the same locations. I have a Gainward Phantom GTX680 card which is technically non-reference, and I successfully modified it. You could actually try a part-mod. If you want to use it for virtualization, I read somewhere that Tesla K10 is supported for PCI passthrough, which means you wouldn't even have to remove the resistor controlling the 3rd nibble - only remove the one controlling the 4th. That should give you ID 0x118F for Tesla K10 and you might find it works just fine. Best of all, the resistor that controls the 4th nibble is on the back of the card, which means you wouldn't even have to take off the heatsink. Please report back if/when you do it.
This is awesome advice, thanks. Can you help with the identification of the resistor(s)? I will take a pic of the card when I get home. Also, do you know if SLI will work if I pass through both cards to a VM?

Have you checled the 680 photos posted here on the forum that show the location of the resistors? Have you had a look at your card to identify if the resistors are in the same place(s)?

Not yet, I will do this. I am keen to know if SLI will work or not. Or is it that K series or Quadro don't allow for SLI??

I have never tried SLI - I'm pretty sure Grids/Teslas don't support it so the driver doesn't expose it. Then again there are a lot of extra limitations in a VM, I noticed that several options that appear on bare metal don't appear on the VM with the same card (e.g. on XP64 domU the PhysX options don't appear, but on bare metal they do). So I wouldn't pre-emptively expect SLI to work, but if you discover otherwise, please, do report back.

If I manage to bork both of my 670s I will post it here. If only I had money to burn on the Palit 780ti , I would love to know if this could be converted to the pro equivalent.
Due to popular demand, I have finally found time to write this up. I had to rush it a little, but hopefully you get the gist.

Any questions, please ask away, and I'll update the article to expand on those points where appropriate.

Fantastic! Please let us all know when you have finished your Kepler guide, awesome work.
Thank you for the work in this thread. I am interested in modding a Titan to a TCC enabled device. It will dramatically improve performance in Cuda. The background information is that Titan uses the WDDM display mode driver, which incurs a massive delay every time a kernel is executed. The TCC mode does not suffer this delay because it bypasses the windows WDDM driver.
From what I read, I need to solder a resistor on to the board, flash a K20c bios, and do a hex soft mod? I have very little experience in any of these steps. I will re-read the thread to try an absorb it all, but if there were a guide to go through these steps for beginners, I am sure it would be very popular and greatly appreciated. Thanks again for the hard work here.
I just wanted to post my experience on average ebay/amazon used price for top notch cards!
Average sales price:
Grid K2 : 1650$ [Geforce 690 new cost $1000 !!]
Tesla K10: $1600 [ same thing as Grid K2 mostly]
Tesla K20: $1600 [k20 is almost like K6000, Quadro K40 is K6000 exactly!]
Quadro 6000: $690 [ older FERMI model that works great with ESXi but doesn't have VGX]
Quadro 4000: $200 [ older fermi model, no ecc]
What I'd like to do is locate possible KEPLER cards that would be a good conversion (sensible to hack)!
Hacking a $1000 Geforce 690 to become a $1650 grid K2 seems a little illogical (risk versus cost)
But hacking a $120 Quadro K600 or NVS into one fourth of a Grid K1 might be a good value!
Do you think one of these hacked Quadros could drive IBM's T221 3840x2400 monitors?

things are bout to change. Let's say big monitors and fruit. soon. that resolution will be everyday ordinary very soon.
I'm not going to hold my breath. People have been saying that since 2003 and it has failed to materialize. There is still no other monitor that will do 3840x2400. The closest is the new Asus that does 3840x2160, and that's 31", which is too big IMO - too much looking side to side. 24" is about the limit of what I'd consider nowdays (having had a 30" Dell before the T221s).
Have you noticed the grid K2 and it's USM's pci-id is very close? I think you might be onto something when you said software. Perhaps the card is dispatching nearby pci functions to enable the grid vgx licensing?
I'm going to get some dinner and take a close look at the bitmask pattern of K2-> K2 USM and K1-> K1 USM , perhaps there is a pattern to this madness.
For example for "Grid K2"
- Physical Function PCIid: 10ed:11bf - GK104GL [GRID K2]
- Virtual Function selectable from
PCIid: 10ed:118b - GK104 [GeForce K2 USM]
PCIid: 10ed:118c - GK104 [NVS K2 USM]
PCIid: 10ed: 11b0 - GK104GL [Quadro K2 USM]
PCIid: 10ed:11b1 - GK104GL [Tesla K2 USM]
All this just to change name in windows without any performance benefit in professional apps, look at this charts!
