so:
1- first of all, do fresh install of 375.70 (its better)

2 -Go get the file (nvlddmkm.sys) in the location i told you. (System32\DriverStore\FileRepository\nv_dispi.inf_amd64_7209bde3180ef5f7\%_nvlddmkm%.sys) copy it into your different sliauto 1.6 paste and patch it.

3- Del your install file and paste mine there, (its already edited with the location, so you good to go.

4- open MSconfig click on 2ºnd tab (boot up) and check the box secure boot and minimum. it will ask you to restart, do it

5- after the restart, you just need to open your different sli auto paste and RUN AS ADMINISTRATOR the install file, it will tell you in the end that 1 file was sucessefully copied.

6- you need to go on system32 paste and open msconfig from there, and disable the boxes you enabled before, (disable the secure boot) it will ask you again to reboot, do it

7- it should be working now... but you might see some test sign water mark, to disable it run CMD AS ADMINISTRATOR, paste this: bcdedit -set TESTSIGNING OFF and click enter

8- each time you turn on the pc you will need to do this: click on window button on left botton corner then the wheel for definitions, Update and security, recovery, on advance boot click reboot now, trobleshout (2 icon), advance options, boot definitions, reboot. Last click on number 7 ( disabled signed controlers)

My windows is in portuguese, some translations might not be 100 accurate, but i hope you unterstand all

if you dont understand try follow this video:


i made this "tutorial" a while ago, use the Install file that i have here in attachtments, it's already properly edited and ready for work

Thanks for your effort.
Your Install File worked fine. I´ve got no error messages. After i exchanged everything with the install file and reboot into normal mode the driver won´t load and if I try to open the control Panel it tells me, that there is no nvidia gpu installed. I can only fix this if i reinstall the nvidia driver.

In my case, Install file should be exec. in Administrator account and Testmode enabled ; i guess windows is not in testmode

I used the lastest version found one page 89 - 1.7 with the updated install.cmd. Surprisingly with driver version 382.33 this works almost flawlessly with my triple GTX 780's. I'm able to SLI them and benchmark them with firestrike with no issues in windows test mode. The problem I'm stuck on is I cannot play any newer games with either windows test mode or with driver enforcement disabled. If I turn off test mode my driver doesn't load correctly with windows - on windows 10 x64 pro. I'm assuming the issue im running into has to deal with driver signature b/c if i turn off driver signature my drivers work. This is an issue b/c easyanticheat and uplay both won't let you play any games. Could someone upload me a working version of nvlddmkm.sys so I could play games again, or explain a simple way to fix the issue I'm having occur?

Unfortunately no.
Switching driver signing to test mode is the price you have to pay for the DifferentSLIauto hack to work.
And Uplay does let you play games in that mode (at least some few that I have), just some multiplayer games which use easyanticheat, like WD2, are exempt.

Probably yes.
Avoid slot PCI_E4 and it should even work without DifferentSLIauto, since you'll have at least x8 PCI-E speed, which is the minimum required for nVidia to unlock regular SLI.

Since you have three identical cards and your mainboard is capable of giving x8 speed on up to four PCIe slots, you probably don't need this patch at all.
So first check whether the three GTX 580 (either in slots 1/3/5 or 1/5/6) unlock the SLI option in nVidia panel.
Maybe the nVidia driver tells you to install SLI bridges, which would be a positive sign that SLI will be working as soon as you add the bridges.
Do you have such SLI bridges ready?

I read in your system spec that you already have an SLI system running, so you could try using that bridge and make two 580 work in SLI first.

YES i have sli bridges but the thing is on msi site the 890FXA-GD70 not support SLI so i'm a bit worry though, i haven't try SLI on non SLI capables motherboard ......

Ok, so I understand that although your Mobo basically features everything you'd need for SLI, it seems to lack the certification in the BIOS...
In that case DifferentSLIauto can be the missing piece.

I recently did a clean install of it and posted a step-by-step instruction here:
https://www.techpowerup.com/forums/threads/sli-with-different-cards.158907/page-88#post-3644795

It relates to driver version 376.60, but it should be the same apart from the name of the driver directory (nv_dispi.inf_amd64_xxxxx).

I Can Confirm DifSliAuto Ver 1.7 Works on Windows 10 Pro with Nvidia 382.33, After combining different methods. Thank You To JameszZzz , Veiker, Pinkpanther and Many Others. Posted Below is the Complete method Combined all in one place for anyone who would like to try.

Download Version 1.7 And Veikers install file

https://www.techpowerup.com/forums/attachments/differentsliauto1-7-zip.88372/

https://www.techpowerup.com/forums/attachments/install-rar.83099/


1. Disable UAC
2. Disable Virus software
3. Delete old Differentsli folder.
3. Open "run" certmgr.msc, delete all differentsliauto certs.
4. Boot into safe mode, run DDU, Display driver uninstaller.
5. After reboot run reg cleaner and ccleaner.
6. Install NVIDIA drivers clean install. reboot
7.Run cmd.exe as admin and enter:
bcdedit.exe /set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit.exe /set NOINTEGRITYCHECKS ON
bcdedit.exe /set TESTSIGNING ON

8.Delete install in difsli folder, replace with Veikers install file located above.

9. Go to C:\Windows\System32\DriverStore\FileRepository sort by date and you'll find a recently created folder named nv_dispi.inf_amd64_5518e59e8d3b48f4. Or whatever yours is named, Look for the newest 1.
Copy that text into your clipboard and in Veiker's install script replace the three instances of nv_dispi.inf_xxxxxxxxxxxxxx
Still in that folder (nv_dispi.inf_amd64_5518e59e8d3b48f4), copy nvlddmkm.sys and paste it into your DifferentSLIauto 1.7 directory

10. DISABLE graphics cards indevice manager
11. Run the patch (DifferentSLIAuto.exe)

12. <shift>-Restart into Safe Mode
Run the Install.cmd as admin. You should get a certificate installed and 1 file successfully copied. Copy nvlddmkm.sys in C:\Windows\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_5518e59e8d3b48f4\ "TO" C:\Windows\System32\drivers\ and Paste it Here.

13.Reboot Normally, Enable Graphics Cards in Device Manager. Then Reboot again. Upon Restart the Enable Sli Option Should Now Be available. Enable SLi, Turn UAC back up and Turn Antivirus back on and Reboot.
