Hi. I just modded a zotac GT640 into a Grid K1...
It identifies as a Grid K1 under nvflash but under esxi shows up as a Quadro 410.
Has anyone experienced this issue?
Good day for everybody!
As I can see, the most people successfully modified their Geforce cards into quadro/tesla used them later as a videocard - but!.. Does anybody try to use modded cards for computations? (Ansys, for example, or other FE program)? For example, in Ansys manual "The following cards are supported: NVIDIA Tesla Series (any model), NVIDIA Quadro K5000, K5200, K6000, M6000 .... For NVIDIA GPU cards, the driver version must be 346.59 or newer."
So the question - is it possible to modify geforce into tesla/quadro with active TCC support?
I would very appreciate if somebody answers me.
p.s. Sorry for my English - and "yes" twice - I am completely newbie in such a modding, and I tried to read all the thread...
p.s.s by the way - even on the devtalk.nvidia.com there is a thread with the same content! am really suprised...
i think the key is driver
geforce, quadro, tesla they have exactly the same core
different point just like frequency, ram size and ECC, better power supply, stability...
if driver ok, others also ok
I know this thread is pretty old but it was interesting enough for me to play around with the idea and it just so happens that a cousin of mine had just upgraded his GPU and agreed to give me his old 680. I followed the instructions (thank you!!) and was able to mod it into a Grid K2. My intention was to have it drive a virtual machine, so I put xenserver 7 on that machine - ran lspci | grep VGA and sure enough it reported it as a Grid K2. So far so good, right? But then I built the vm and I found I couldn't install the driver no matter what. I downloaded an eval windows 10-64 enterprise image, then I tried pro and even ported over my daily driver's activation code...nothing. I figured it was time to get creative so I started to try different things, but so far nothing has worked. I've edited the *.inf files to list the 11BF hardware ID's, I tried all the sections and the descriptor at the bottom. I also tried doing it backward and editing the registry to "re-normalize" the PCI hw ID back to a 680 to see if the drivers would install then...I got past the nvidia hardware check, but it still failed. If I tried to do it manually I'd just get a windows dialogue saying the driver had a "problem" with windows and windows couldn't install it. If I tried the K2 driver, it installed but windows reports a problem with the hardware and the device couldn't be initiated. And if I tried an older driver, it says it can't work with this version of windows.
So I'm kinda racking my brain at this point - but before giving up thought it would be a good idea to ask you guys, since you all discovered this in the first place. I know it was a while ago...but what am I doing wrong? Is it because I'm trying to run this in a pass-through VM? Or is it that you guys only got this to work with an older OS like windows 7? Is it supposed to be a 32-bit OS and won't work on x64?? Or is there a custom or specific driver that you guys used to make it work (and if so, do you have a download link)?
Thanks so much!!
OMG! Just randomly check on this thread again to see news and you finally came back, this make me wanna cry out of joys and excitement!
Thanks so much for the instructions and the explanations, gnif! I can grab 99% of the process now. However, as you mentioned, only 1 of 2 nipples for each strap is populated, but the process is to add a random 10k resistor to find the target un-populated register. It could leads to a situation where both nipples are populated! Is this a contradiction or am I missing something here?
On the other hand, I wonder if randomly "close" the circuit with a 10k test-resistor do any harm to the card?
About the suggestion on creating a transparent image to track down resistors (or traces?!), I know it would help but the thought of these PCB are all multi-layer makes me feel (somehow) insecure!
Hi to all,
i am new here. I read this thread from beginn to end and i have 2 questions about
GTX690. The member "gnif" is a genie (thx for your efforts) but after burn his card he dont share any
new picture with dual k5000 cpu´s.
My quetions:
1. Is dual K5000 possible?
2. Must i change the firmware or any hacks?
PS: I attached 2 pictures is this correct resistors for the GTX690
Sorry for my bad english
Hello all again I have good news.
I successfully modified
Zotac PCI-E NV ZT-60206-10L GT640 Synergy 2G 128bit DDR3 900/1600 DVI*2+mHDMI RTL
To NVIDIA GRID K1. It is working fine. passthough works too. BUT Device ID mofidication posible only after bios modification. Bios modification is needed only for specific vendors.
upd:
myweb found resistor places for Asus GT640-1GD3-L, no bios modification is needed. pic attached to post.

Hi, I have a question. I have the following card https://www.asus.com/Graphics-Cards/GT6402GD3/overview/ its device ID is the same like for Zotac but the point is non of the presented versions ot this GT640 has the back look like this one. Thus I do not know which/where are responsible resistors... Are you able to help somehow if I send the back view pic ?
Thanks and regards
