Looking at the new gtx 650 Ti Boost, it looks to be almost identical to the Quadro K4000 short the memory (same processor and cuda core count.) Would it be a hardware only or a require bios or softstrap mod as well to be done properly?It is impossible to say until someone get bios from card.
Hi, everybody! Thanks for an interesting topic.
To me it is most interesting "mod GTX 680" to quadro k5000. Now I have no any graphics card based on the chipset gk104. Therefore, I am free in its choice. The most promising option I see GTX 680 + 4GB mem. For K5000 is important to have the largest possible volume of onboard memory.
With only one such card was a successful experience modding. EVGA 04G-P4-3687-KR GeForce 4GB GTX 680 mod to K5000. Unfortunately, reefjunkie did not described the details of this mod. It is possible, P?B was the same as with GV-N680OC-2GD
I consider following variants of devices:
Gigabyte GV-N680OC-4GD
ZOTAC GTX 680 4GB [ZT-60103-10P]
EVGA GeForce GTX 680 FTW+ 4GB [04G-P4-3687-KR]
EVGA GeForce GTX 680 FTW+ 4GB [04G-P4-3687-KR]
Pictures with a PCB-s I have not found.

Unlike the GV-N680OC-2GD, Y1 repositioned to the rear side. Different connectors resistors. Independently I do not find their location.

Video card similar to GV-N680OC-2GD. It is possible, it would be similar mod. The board kept the reference design. It is strange that nobody had chose it for the experiment.

It's identical to the 2GB one and I think this is the reason reefjunkie didn't elaborate on what was done.
Gigabyte board is not a reference, they have redesigned it (look it has 6+8 pin power connector).
Zotac has a board with 6+6 as well as EVGA and PNY (which I believe are identical).
So...that's not possible to mod a Gigabyte GTX 680 4G to a K5000?
and check what power state it is in when running the benchmark.

I can confirm the mod done by blanka.

But I pimped it a little bit.
670GTX to K5000 works!
R4 on the front side.
R1, R2, R3 on the bottom side.
K5000 works absolutely stable for me, but has no performance increase in SPECviewperf. I tested with few different Quadro drivers.
Summary
GPU Name R1 / 0-7 4th byte R2 / 8-f 4th byte R3/ 3th (high) R4 / 3th (low)
GTX 660Ti 20K None None 25k
GTX 670 None 10K None 25k
tesla k10 none 40K None 25k
Quadro k5000 none 15k 40K none
grid k2 none 40K 40K none
I flashed it (EVGA 670GTX 2GB 915MHz) with the K5000 bios from techpowerup.
"nvflash.exe -4 -5 -6 K5000.rom" had to be used because of different subsystem and board id.
It started with minor pixel errors but booted into win7.
After driver installation and reboot win7 didn't start anymore.
Flashing it back worked without problems.
Was wondering if there was anyone who has successfully got the EVGA GT 640 cards working?
Does this help? I'll go ahead and post my pic of the back as well.
I will be getting a Zotac ZT-60106-10P GTX 680 with 4GB RAM soon-ish and proceed to start testing..
The goal is a K5000.

Hi, shlomo:
Thanks for your update. I am just too lazy to fine tune my workaround for those resistor.
About the reason your windows can't start up, it is because you use the original "K5000" firmnware
DO NOT USE ANY OTHER FIRMWARE EXCEPT THEY ARE FROM THE SAME LAYOUT
The original K5000 firmware is use for 4096MB board with GTX680 layout.
Since we are using GTX670/GTX660Ti, Use the original firmware and modify the PCI Device ID is enough.
Please be aware that EVGA's firmware has 2 place that contain its Device ID.
Please use Hex editor and search 8911(hex value of GTX670) and change it to BA11.
Then use KaplerBIOSTweaker to fix the checksum or any utility you like.
This will make the board run at K5000 smoothly without any problem since you didn't change the firmware at all!!!
The problem of mine is that I got a 4G gigabyte GTX 680....which is not the same as EVGA...I can't find the correct resistors on the board...
Could someone help please?
