[MOVED] Hacking NVidia Cards into their Professional Counterparts

[amin_eshgh]

I said that because 650 ti boost have same hardware like k4000 but 660 have more shader

[Patribus]

sorry, but can you explain waht you mean with "more shader"?

best regards

[amin_eshgh]

My mean is that your card should have 928 core but 660 have 980 core

[Patribus]

But which Quadro card would correspond to the 660 one than?

[kzyswd]

I want to make one thing clear. Quadro cards usually has lower clock speed and such, which makes it slower in gaming compared to Geforce but makes up with the "better" driver for certain applications. Since hacking a Geforce into Quadro doesnt change its hardware, does it mean it will have the same gaming performace as before it was hacked, but with increased performance for professional applications?
In other words, will a hacked GTX 690 + qudaro driver still performs the same as original Gtx 690 in gaming, but will also perform as well or even better in professional application compared to K5000 ??

Hello

I have discovered this thread a while ago... since I had success soft modding an GTX470 into an Quadro and using it via VGA Passthrough/ESXi 5.5 I also wanted to try the hard mod version.
I got my hands on an GTX680 (Gainward board) and tried to remove the resistor on the back, I seemed to have success.
The card identifies now as Tesla K10 - however on my  first try yesterday I wasnt able to load any drivers, I tried 337.xx GeForce (WHQL), 331.xx GeForce (WHQL) and also some Quadro-Tesla-Grid 331.xx.
With the modded GTX470 this is working fine (running on Win7 x64 with 337.xx driver).
The error code is always 10 (unable to start the device).

Any ideas, could it be an ESXi only problem?
Or would you say I did break the card?
I'll try it again either today or in a couple of days (depending on my time...).

Hi all again
I successfully modified SPARKLE SXS4501024D5SNM GeForce GTS 450  1GB to Quadro 2000
board is reference nvidia gts 450 http://www.ixbt.com/video3/images/ref/gts450-scan-back.jpg
upd:
gpu passthrough works fine.

Initial values are:

index	meaning	resistance
1	3 byte value D	none
2	3 byte value C	35k
3	4 byte values 8-f	none
4	4 byte values 0-7	25k

device / resistors table

device name	R1	R2	R3	R4
gts 450	none	35k	none	25k
Quadro 2000	35k	none	5k	none

furmark: http://www.ozone3d.net/benchmarks/furmark_192_score.php?id=120616

Today, i do this hard mod with Gygabyte NVIDIA GTX 650 4gb overclocked version(GV-N650oc-4GI), i convert to Nvidia Quadro K2000, the pcb is the same that any (gtx 650), i remove the Resistor number 1 with value 25K. For the resistor number 2, i bought a smd resistor 0402 +-5% 39K OHM (similar to 40k ohm resistor) its works, i recomend to buy a smd flux and desolder to made more symple this hard mod. For the resistor number 3, i remove it, and then i put this resistor in the resistor 4 place. This graphic card don't need any bios mod with hex edit, only desintall any old graphic card driver, and install a clean quadro driver.

[amin_eshgh]

congratulation Pluger 
Kzyswd : no because in quadro driver Physics is remove.

hello,
it's possible to hack my 560ti to use a quadro driver?

[Patribus]

Hello, my question again: is there some Wiki where an overview of the mods is available? IT is really diffucult to maintain the overview in a forum like this one.

And if not, should we start one?

Best regards

Hello , can you please check the value again ?  If it is None 35K None 5K, then what is the device supposed to be? I read up in the Nvidia Device ID list.  Quadro 2000 suppose to be 0308 right ?  Btw, I tried to mod like you with the PNY GTS450 but for some reason it turns out to be 0DDC which is unrecognized as anything.  Btw, do we need to change any BIOS? if so, can you please show me how? Thanks a lot ... !!!


Looking to hear from you soon.

aloha community!

i am very interested in modding a Nvidia Card into a Grid k2 to share it with multiple VMs.

What i want to do is to use the rig (xeon 5650 6C/12T@3,8Ghz+24gb DDR3 Ram + hopefully false Grid k2) as a Host for multiple Windows instances  which i'd like to share to some old notebooks (using gigabit ethernet) for gaming purpose. So for the next LAN for example nobody needs to bring its full rig and stuff but just its notebook and everybody gets still good performance (using 1C/2T+ 4GB Ram + 1/4 Grid k2 + domU in own hdd or on SSD).

is this doable or is the performance via gigabit ethernet too slow?

Also i read that this mod works with GTX 680 2 GB.

Since a GTX 770 is cheaper and basically the same card in specs i wonder if the mod would still be possible with GTX 770?


Also i'd like to know how the modded card performs when shared fully to just one domU?

is it even possible or is the Grid k2 "divided" into separate parts which i share to multiple VMs?

if it is that way, had anyone tried to solder a switch to the resistors? if i get it correctly you 'just' need to remove two resistors at the gtx 680. that way it should be possible to solder a little switch to choose between 45k and ?. that way when the machine is shutdown i could just switch between the 'different' cards. when starting with the gtx 680 i boot into the hdd my windoze or linux domU is located at. (which will propably result in issues with the driver(?))

hope you guys can help me!

i really like to get that discount of about 1800€ on a Grid k2

[dreadkopp]

sorry, two pages ago someone modded his gtx 770 to grid k2 ...

so i will get one soon, if necessary someone can help me to detect the correct resistors?

Greetings!

Hello,
first thank you all for this very helpful thread!

I was able to hardmod my GTX 770 to a Tesla K10.



But none of the temperature sensors are working now, and I can't access the Nvidia controll panel(there is no display attached to the gpu )
Should I flash a K10 bios, to get all the stuff working? I also can't play any game
Maybe someone can help me solving these problems


EDIT: Made it a Grid k2 and all works perfect now!!! Thank you all so much!!!

How does this perform in GPGPU benchmarks? Is the double precision float numbers comparable to a real K2 or is the performance still crippled? You can find such a benchmark in Aida64 under Tools -> GPGPU Benchmark

Hello everyone,

for those who have time,

I started a Wiki to gather all the info in this forum in a struktured way.

The wiki is still kompletely empty, I'll start filling in out in the next few weeks, mainly with all the info related to the GTX 660 card (which is the one I have).

PLEASE FEEL FREE TO EDIT THIS WIKI located at http://aidivn.wikia.com

TO be honest, I still did not check how the permissions settings are, but I'll change them step by step, so everyone can have access to edit.

Well, that's it for the moment.

Best regards

Any idea if the new 980/970 would be hackable?

[vacaloca]

I don't believe there are any professional model cards with GM204 chips, so my guess is GTX 970 and 980 can't be converted to anything else.

Would this be doable? Interested in TCC... From:

NVIDIA_DEV.1380 = "NVIDIA GeForce GTX 750 Ti"
NVIDIA_DEV.1381 = "NVIDIA GeForce GTX 750

To:

NVIDIA_DEV.13BA = "NVIDIA Quadro K2200"

What do you mean ? Can you please tell me what did I read incorrectly?  Last Week, I tried to put on the VR 1k - 100K in the forth bit; however, the Device ID seems like it doesn't change when I turn to 5K or 60K.  Do I need to modify the BIOS firmware in order to make it work?

Thanks a lot for your advise !

Hello,

Due to the limited space around the single pcie x16 slot, I'm thinking about purchasing GTX 760 "MINI" card. I found two models:

1) ASUS DirectCU Mini - GTX760-DCMOC-2GD5
2) MSI N760 2GD5/OC ITX

I wonder if someone has already managed to convert one of these "MINI" GTX 760 cards into the Grid K2? Looking at the attached pictures it seems that the resistors have been placed somewhere else.

Alternatively, what card would you recommend for virtualization purposes (vDGA / vSGA), which does not require a lot of soldering and would fit into the Intel S2600CP4 mainboard (graphics lenght is limited by memory slots ). It would be great if the card wouldn't be too loud.

Looks like the days of softmods might be over...

hey guys, made an account especially for this
so i've read  through most of the forum and decided im keen  to get my fingers into my MSI 660Ti Power Edition and turn it into a k5000. I mainly need it for ansys  and cad at home: unlocking would mean i could start using the card to solve, instead of having to use the cpu 

 From what ive read, i still havent been able to identify the resistors. would be awesome if anyone has any clues as to where they are. ive attached pics of where i think they might be  .
Correct me if im wrong, but i can just use the same resistor values as for the 680, correct?
If there is still any mystery about the 660ti, id be willing to donate the card, if anyone wants to give it a shot

thanks guys, you're amazing

Hi Guys. I found this forum searching for 'Hack GTX 780 into quadro' on Google. Is it possible to hack a GTX 780 into anything? I was just about to buy a Quadro anyway so I don't mind trying. If someone can guide me through what I need to do.

Thank You

Daniel

Hello,
now that I have a gtx770 @ Grid K2 I tried some virtualisazion scenarios:

1. XenServer with XenDesktop: VDGA works, but with VSGA the VM's dont start.
2. ESXi with Horizon View VDGA: works, but no  VSGA.
3. Remote FX: I can enable Remote FX in the Win 8.1 Enterprise VM. Also a little bit of VRam(165 Mb) is allocated by the VM. Sadly there is no difference in performance between software gpu and the fake Grid K2.

The Host is a Windows Server 2012 with i5-3550 and 16Gb of Ram
The VM is a windows 8.1 Enterprise

Do I need to modify the bios or flash a modified bios from a K2 Grid to my moded Gtx 770 to get the full performance/features?
Please help me with this problem
