[MOVED] Hacking NVidia Cards into their Professional Counterparts

[Vladimir]

Hi everybody!
Thanks for great work and a lot of usefull information!

Successfully hacked two cards only with Nvflash:
Palit GTS 450 to Quadro 2000 - Works with passthrough in Esxi 5.5 and in Xenserver 6.2 and in Xen 4.4
Inno3D GT 9800 to Quadro FX2800M - Works with passthrough in Xenserver and Xen, and does NOT work in Esxi (fails with BSOD)

Third card - Palit GTX 660 2 gb, tried to mod it to a K4000 ID of 11FA.
Resistors was replaced in accordance with THIS post.
On this Palit pcb in area of flash chip the same as on EVGA GTX 660.
I had no 15K resistor so I put 16K. And it's looks ok. The 4th nibble is A.
But..
1. 3rd nibble is buggy: Mostly it's F, but sometimes (eg. after xen host reboot) it became "E". And even if I put 40K resistor in R3H on topside.
2. Passthrough does not work. Tested in Xen when ID was ok - 11FA. In device manager there is yellow triangle - error code 43.

Any suggestions?

@axero

sorry for the late reply. Here are my results using 332.76 quadro driver on a win server 2012 R2:

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"

I am interested in this too... Both have the GM107 chip, so in theory would be doable.
750 Ti has the full core count (640:40:16), like the K2200. But the 750 Ti is 1/4 of the price of K2200.

I have an MSI GTX 780 3GB OC Twin Frozr (Revision B1 chip) core config: 2304:192:32(12 SMX) GK110

is it possible to convert it to Quadro K5200 as it has the same core config: 2304:192:32(12 SMX) GK110 but has 8GB VRAM

[SoNic67]

Take a picture of the back, to compare it with the K5200... Area close to the chip.

i dont know where to look at

[SoNic67]

You need to show exactly just the central region that I showed - around chips U504, U505 and the four screws for the cooler.
It seems that your board is missing one of them...

i have no idea where the chip stuff you're talking about.

o/ all

post is very interesting.

I search to soft mod a gtx 470, and it's difficult for me, i'm french and my english is bad.

So i read 73 pages of this topic, but i dont understand how i change straps and device id on my gtx 470.

I take this subject : http://www.davidgis.fr/blog/index.php?2013/09/18/969-xen-430-vga-passthrough-gtx-480-soft-moded-to-quadro-6000

And this : http://www.altechnative.net/2013/11/25/virtualized-gaming-nvidia-cards-part-3-how-to-modify-a-fermi-based-geforce-into-a-quadro-geforce-gts450gtx470gtx480-to-quadro-200050006000/

I want soft mod my gtx 470 evga>quadro 5000 for use passthrough esxi/xen passthrough.

I don't know how i must begin...

I have my bios gtx470, i download bios quadro 5000, i open this file with and heximal editor, then i compare 2 bios.

After i'm blocked.

How i find device id on heximal editor?
What's strap i must changed?
I think that my problem is how i undertand langage english.
I don't undertand what is "little endian"?

thank you for answer.

Regards,

Successfully hacked brand new MSI GTX N660 Gaming OC edition to Quadro K4000.
Works with passthrough in Xen 4.4
Now i have tripple-headed virtual gaming PC  O0
And only one is sad: previously installed 3-screen multiseat system on my Linux Mint 17 x64 Qiana does not work with Xen because of proprietary drivers (multiseat needs proprietary drivers and Xen needs nouveau)
Now I am installing ubuntu server with Xen.

Answering my own post:
1. To fix 3-rd nibble to "F" put pull-up resistor 40k (or less) between flash VCC and ADC input for 3-rd nibble (see picture).

2. Palit GTX 660 was returned to owner. He was worried and did not want to try again to remake it. So I can not check if it works in Xen. I am sure that the pull-up resistor would correct 3rd nibble on it too.

Hi Vladimir,

previously installed 3-screen multiseat system on my Linux Mint 17 x64 Qiana does not work with Xen because of proprietary drivers (multiseat needs proprietary drivers and Xen needs nouveau)

Could you explain that statement a bit? I'm planning on doing VGA passthrough to a Linux VM and I didn't think Xen needs nouveau. Thanks!

Xen needs nouveau drivers if You want to run gui (gnome, kde etc.) on Dom0. There was 3-seat multiseat system with three xorgs running for three users on my PC with Linux Mint. My idea was to use Linux Mint as base system, and if one user needs to run windows guest in xen for gaming, he can just run script to log off, stop his xorg process, unbind VGA card from nvidia's driver, bind it to pciback driver, add his USB controller for his mouse and keyboard to pci-assignable list, and then start windows guest. And after shutdown windows guest - automatically bind all devices back to dom0 and start xorg again. But it looks like there is no way to do this on multiseat system.

Didn't know that, thanks for your explanation.

I would be extremely interested to learn how verybigbadboy was able to convert his 680 into a VGX/GRID K1

Just remove resistor 1 and 3 showed on picture in my first post and you will get grid k2

Also now I am trying to modify gts450 to quadro 2000. But I have a problem with getting 4th symbol. I think it is possible to modify almost all nvidia cards which have counterparts. Gts450 have similar way to setup device id.

I think gt200 series can be modified too, I looked at died gt240 and I think I know where are right resistors.

What i need to convert my gtx 680 to a grid k2 simply by removing those 2 resistors, nothing else ? I don't need to solder anything right ?

Sorry im new here and i just want to confirm after a 73 pages thread 

[drpc]

Asus gtx680 directcu 2 Need help for resistor location. They have there own pcb and the layout is different with other brands.

I can not make sure where is the resistor for hardID control.

I have Multimeter and electric iron.

Any information will be appreciated.

luyi.  If you are in suzhou, China. We can have a meet.

P.S.

And the back side details of aroud GPU area.

Thank you very much, dear Gnif, blue or red area?

Blue, you need to learn a little about what you are doing here, the red area is clearly wrong as these are sufrace mount capacitors.

Yep? thank you very much. I will check the value tomorrow.

[drpc]

I got the value:like this

top 5K 5K 5K 45K
down   45k

Dear gnif, any suggestions?

I had killed my GPU, If you don't have enough knowledge about electronic. please don't like me as a GPU KILLER.....

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.

There is already a wiki for it, but nobody seems to have bothered populating much into it:

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

"NVIDIA Alerts Nouveau: They're Starting To Sign/Validate GPU Firmware Images"
http://www.phoronix.com/scan.php?page=news_item&px=MTc5ODA

The days of softmods finished with the GTX480. Everything after that had to be hard-modded anyway. And there is no point in chasing bleeding edge drivers with anything but a bleeding edge card.

For those of you wanting to use VSGA type solutions, there are known bugs in the Kepler firmwares, and only the latest firmware for the K2 works properly. All the GeForce cards have firmwares where the bugs aren't fixed, so it probably won't work. You could cross-flash a K2 firmware (after you have edited the memory size initialization block) onto a GeForce, but you will lose all video outputs on the card, and I don't think anyone has tried this.

If you want to play with VSGA you may be better off with a GTX480 modified into a Quadro 6000. If that doesn't work, later cards probably won't work either.

Read through this thread fully, there are heaps of tips on how to do this. If you are asking such questions perhaps you should not be performing this modification.

Anyone got a 980? I would be interested to know if the 780ti resistor on EPROM mod would turn this card in to a K80?

I do not believe so, nobody I am aware of has this card yet and is willing to hack on it.

I am willing if there is a chance that it my work. I hacked my 780ti to K6000 so comfortable soldering on to the pcb if required.
