SLI with different cards

[afraxass]

The simple answer does not explain, how you managed to patch the professional version of the nVidia driver...

if driver version is same, Quadro's nvlddmkm.sys is same as Geforce's

 

[P!nkpanther]

Good to know, if they do this consistently.

Care to explain what the point is of these certified versions?
http://www.nvidia.com/object/quadro-certified-drivers.html

They could as well simply certify one of the consumer drivers then...

 

[slaine_mcroth]

Simple Answer is Yes, I used two K6000 on Supermicro board

Yes i confirm it works with geforce drivers 385.28 and 1.7.1 patch

 

[tytynono]

a solution for me?

Please JamesZzzz tell me a manual method.

Hi guys, folowing this thread for a long time now but can't figure out how to make solve my problem :
I've got an HP Z800 Workstation wich is capable of QUADRO SLI.
And 2 GTX 780 inside.
My only probleme...I don't have the "nvlddmkm.sys" driver I can't find it anywhere...
So if there is another driver I can use, or if someone can send it to me, that would be great ^^
Thanks guys

I would like to offer a bounty. $25 USD (or equivalent currency) via Paypal to the person that gets the patch working for the Shadow of War driver Nvidia will VERY soon release. Another $25 for the destiny 2 driver they will release later this month. I know this isn't much but I'm a student and I'm just hoping to be able to play these games optimally when they come out.

This is assuming these games support SLI, if SLI ends up not being supported, this bounty is not valid.

Edit: Shadow of War driver is now available as 387.92 WHQL

...I don't have the "nvlddmkm.sys" driver I can't find it anywhere...

Device Manager → Double click your main display adapter → Tab: Driver → Driver Details
There you find the path where the active nvlddmkm.sys is located.
Of course only if you actually use the nVidia drivers and not the Windows generics.

Thanks !, I'll look in there tomorrow, my WorkStation is currently off .
And yes, I'm running Nvidia driver 385,something...

I spent the evening attempting to get two Quadro 5000's to run in SLI on a Dell T5500 workstation with Windows 10 Pro. I noticed several people have used Quadro's with DifferentSLIAuto and managed to get it to work. I haven't had much luck yet and I feel that I'm missing something simple. I read through several of the guides people have posted (primarily P!nkpanters) and it left me with a few questions.

Here are the things I'm not entirely sure about:

1) I did notices that the file in which "nvlddmkm.sys" is located is named differently in the Install.cmd
mine is "nv_dispwi.inf_amd64_998aa7ef65f571d1\nvlddmkm.sys" compared to "nv_dispi.inf_amd64_c775b600ccf2cdac\nvlddmkm.sys"

Do I change the file name in the C:\ directory or is there a way I can update in the install.cmd ?

2) When I click patch in DifferentSLI Patcher 1.7.1 I do get "Patching was successful!"

So as it stands right now when I use the install.cmd and I change the file name to match the one listed in the command window I get a "file copy success" and then changing it back to what it was originally. Either way I still end up with a similar result which is upon reboot the drivers clearly didn't take because the display is terrible looking. I've tried also, disabling the graphics cards as well as trying to manually transfer the "nvlddmkm.sys" file but I don't have permission to modify files in that folder. I've tried in safe mode as well but still had the same permissions issue.

I'm using 377.61 Quadro drivers and DifferentSLIAuto 1.7.1.

Here's the video that sparked my interest to do this in case anyone was curious.

Thanks in advance to any advice you guys might have to lend!

Matt

The version of DifferentSLIauto has to match the version of the driver.
1.7.1 matches 385.28, there is no more recent version supported by this project.

Also I'm not sure whether your 460 and 550ti actually can be SLIed, that depends on the bus width of your 460 (must be 192 bit, same as your 550ti).
nVidia in their endless wisdom sold 2 different designs under the same name.

The latter is exactly what you're supposed to do, according to the install instructions: Rename these example paths within the 'install.cmd' to the actual ones, using a text editor.

Can somebody kindly provide me an win7 driver file of 387.92
Discovered some crap in the os detection mechanism
Win7/8/8.1 users should use version 1.7.1 with 387.92 just fine

Meanwhile Win10 users please use the version attached to this post
I've also included an updated version of Install.cmd

 

[CGFlyer]

Hi guys.
I found the right path : "nv_disp.inf_amd64_64f40b686fe9309f\nvlddmkm.sys"
But...how...
I'm not English speaking, so I probably didn' undertand the whole procedure.
I need to pus the driver in the same folder as the patch...but how can I take it ?
Do I also need to replace this in the instal CMD ? if so wich line, nothing resemble it...
Thanks again and sorry if this is obvious for you, ^^

So I have made some progress I think. After using a text editor to change the path of the install.cmd it corrected the issue of an unsuccessful file transfer. Which lead me to a new issue, once I reboot and try and enable the graphics cards windows says that they are not certified. I very well could have missed a step but I feel that I am much closer than I was yesterday!

I had some of the same issues too. Try opening install.cmd with a text editor and look for the lines containing the following:

call "%SystemRoot%\System32\takeown.exe" /f "%SystemRoot%\System32\DriverStore\FileRepository\nv_dispwi.inf_amd64_998aa7ef65f571d1\%_nvlddmkm%.sys" /a
call "%SystemRoot%\System32\icacls.exe" "%SystemRoot%\System32\DriverStore\FileRepository\nv_dispwi.inf_amd64_998aa7ef65f571d1\%_nvlddmkm%.sys" /grant "%USERNAME%":f
copy "%_nvlddmkm%.sys" "%SystemRoot%\System32\DriverStore\FileRepository\nv_dispwi.inf_amd64_998aa7ef65f571d1\%_nvlddmkm%.sys" /y


replace the nv_dispwi.inf_amd64_998aa7ef65f571d1 with whatever your folder is called and save. I used Notepad++ if you want to give that a try!

Also, you should be able to copy and paste your nvlddmkm.sys file into the folder containing the install.cmd .

Hi, Jameszzz

both Desktop and Quadro worked on 387.92
but after windows update(1709), i can't execute "DifferentSLIAuto.exe"
Anyway, patched driver worked perfectly

Thanks. MI

I forgot to mention that the linked version for W10 shows up as 1.6.1 it did work for me but only after multiple tries and it's still a bit wonky. Can't open nvidia control panel at all after reboot to enable SLI but SLI does seem to work.

You're not using version 1.7.1

My script looks very similar, I think it may be related to above.

Edit: Ehh maybe not, I do have the proper full path, however my patcher does show as 1.6.1

 

[LightlyEngineered]

Okay so here's a few screen grabs of what I've done. After I reattempted the bcdedit.exe steps I was able to enable the graphics cards and everything functions normally but no SLI still. I've attached a copy of the guide I am using as well in case I'm missing something obvious.

 

[CGFlyer]

ok 1.7.1 on now, instal.cmd re-iedited but...can't find a way to copy the driver in the patch folder...

ok patcher done but...when I 'launch instal.cmd :

L’opération a réussi.
Le processus ne peut pas accéder au fichier car ce fichier est utilisé par un autre processus.
0 fichier(s) copié(s).
Reboot now for changes to take effect

sorry it's french : (

UPDATE : I rebooted ans still no SLI on the NVidia panel

Do you follow these instructions?
https://www.techpowerup.com/forums/threads/sli-with-different-cards.158907/page-88#post-3644795
It's still valid except that the respective version numbers are higher now.

The install will not work without using that procedure.
The addendum I did in that post may be needed or not, seems dependent on the system.
