    Hi everyone!

    At the beginning this thread was started to research the ways of turning Quadro K3100M into K4100M or K5100M. But when we all cleared out that it's not easy and will require swapping the GPU core - the project was finished. But during this project I found the resistor and their values to change the device ID. That's why I started the new project the main purpose of which is turning Geforce into Quadro cards and wise versa.

    All project info are in 2nd and 3rd posts.

    I'll appreciate for any help on this project! ;)

    HARDWARE MOD
    Recently I've started to research the "HARD MOD" way and found a lot.
    [​IMG]
    Device ID: 0x11B6
    R3:
    20K Ohm
    R4: 36K Ohm

    I've played with resistors and found out the resistance for each ID:
    • 0 and 8 - 5.1K Ohm
    • 1 and 9 - 10K Ohm
    • 2 and A - 15K Ohm
    • 3 and B - 20K Ohm
    • 4 and C - 24K Ohm
    • 5 and D - 30K Ohm
    • 6 and E - 36K Ohm
    • 7 and F - 39K Ohm
    This table will work for GK104 with 7**/8**series. Don't know about 6**.

    SOFTWARE MOD

    Possibly, there is a chance to change Device ID using soft straps, but I need help from experienced person because I don't have enough knowledge.

    UPD: Soft straps does nothing. The only soft mod that could be done is patching Nvidia driver. Or patching system EFI bootloader might help.

    What about comparing performance? 25W is nothing for a K5100M....

    Performance still the same as k3100m have due to driver utilization of GPU components. Currently, I need to change Device ID and I'm close to do that without hardware mod. All I need is some vBIOS and firmware dumps from k4100m and k5100m.

    Looking for people with K4100M/K5100M/780M/880M/970M/980M who can measure two resistor from the second post.

    The benefit from this project is the ability to upgrade at no cost almost every Kepler and Maxwell cards (for example: k3100m to k5100m/880m, 780m to 880m/K5100M, 980m to M5000M and etc.)

    Here's the problem you'll run into. Unlike AMD, nVidia actually laser cuts the extra cuda cores from their chip. You won't be able to convert a K3100M to a K5100M if the cuda cores are laser cut.

    During this week I'm going to play with resistors and Device ID values. I believe, that K3100M/K4100M/K5100M have the same uncut GPU.

    The 3W extra power consumption is probably because the GPU tries to find something you dont have-

    In addition to what ssj92 say, if it was as simple as reflashing cards, GTX 960M to GTX 980M, 7970M to M295X, R9 290 to 290x, GTX 980Ti to GTX Titan X, yeah you get the point...then AMD and Nvidia wouldnt be in business right now.

    You cant reflash cards anymore. Its extremely rare and is sadly in the past
