SLI with different cards

Just google it... :)
 
It's the Install.cmd script you find in the DSLIA folder.
You have to edit it, replacing the occurrences of nv_dispi.inf_xxxxxxxxxxxxxx with the actual path used by your driver installation.
 
i dont know how to do that................. and i had skipped that step and now i only have one screen working,,,,,why did i even bother to try this in the first place... ninvida control panel wont work and im only detecting of off my 1070 not my 1080

this what i got when i installed

Sorry, can't read a thing in that picture; the resolution is way too low.

You need to have basic knowledge in navigating the file system and editing files to be successful in this installation.
Maybe you know somebody that could help you with this...

Anyways, regarding your botched installation, you can always DDU uninstall this driver installation and reinstall nVidia drivers, so no harm done to your system.
 
i got everything back up , i wish i new someone that can help me but is there a video i can watch to get this to work i followed every step to the t except the part of Copy that text into your clipboard and in Veiker's install script 1.6 replace the three instances of nv_dispi.inf_xxxxxxxxxxxxxx ... this is what i need assistance with

how do i do this or is there anyone that can show me?

heres a re upload of the photo
maybe you can see it better now

Looks better now...

Your install.cmd still tries to copy into %SystemRoot%\System32\DriverStore\FileRepository\nv_dispi.inf_amd64_7209bde3180ef5f7\ instead of your actual driver location. You have to open install.cmd (right-click -> Edit) and change all 3 occurrences of nv_dispi.inf_amd64_7209bde3180ef5f7 to the actual driver location. It's just about changing these 3 short strings...

I made a short video how to do that for you. Hope this helps.
 
ahh ok got it, i will try again thanks,... i got it working but everytime i reboot i have to disable driver signature..;[
 
Disabling Driver Signature Enforcement has to be done every time at boot.
That's why you usually do test-signing:
  • Set UAC to the lowest setting in Control Panel\All Control Panel Items\Security and Maintenance
  • Run cmd.exe as admin and enter:
bcdedit.exe /set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit.exe /set NOINTEGRITYCHECKS ON
bcdedit.exe /set TESTSIGNING ON

This method is persistent but has the disadvantage of not being accepted by anti-cheat software of multiplayer games.

may i ask what is the lastest driver version this different SLI support ? ( 100% working on windows 10 ? )
can i play smth new like BF1, ROTR with this SLI set up ?
 
Version 1.7.1 works on 388.71. Seems like any later driver will not get patched.

DifferentSLIAuto only unlocks the already present SLI support of the driver for hardware setups that would otherwise be blocked.
Thus regarding SLI support of games, you need to consult the respective game forums.
 
This sounds interesting. I seem to remember that some company came up with a bridge chip to make AMD & NVIDIA cards work together too and some mobos were released with it. Nothing seems to have come of it though, possibly because of licensing issues. What a shame.

Still, it proves that cards can be totally dissimilar and still work together just fine.

I think you're talking about LucidLogix and their Hydra Engine...?
 
Well im back, sorry for the delay in this post, ..
I can confirm that i can cross fire a 1070 with a 1080 using a bridge. following all the directions it works with 388.71

Took a few trys but thanks yall!

Why? Because the creators are not supporting it anymore? :(
Possibly because the thread is over 6 years old and the OP visits infrequently. I don't think he has even posted here for a very long time.

Actually I meant that the current 1.7.1. patcher will not patch any driver newer than 388.71
But yes, the original creator has left the building and the project is at the mercy of other volunteers, like JamesZzzz

DX12 multiGPU in theory should be able to deliver similar results.

I have a pair of EVGA GTX 970s, an ACX 1.0 & an ACX+ FTW+, and I have followed the guide. Everything says it succeeded but the nvidia control panel is still telling me my SLI bridge is not installed. Are some of these EVGA 970s just never going to play together?
I used ver. 1.7.1, driver 388.77. I'm running an 04G-P4-3978-RX (B-stock) & 04G-P4-2976-KR, Windows 10 latest update.

P!nkpanther, several of your posts were very helpful and are responsible for my success in running DSLIA and install.cmd. :toast:
 
Yep! I followed this post in the last pages, as creators I meaned, creator + updater, even if the Thread is 6 years old I saw latest version is from a while ago thanks to JamesZzz,
let's hope this great poject will be keeped up in the future!

Glad to hear...!:peace:

First, happy to see somebody post their system specs firsthand when asking a question. :clap:
Should be common sense, but unfortunately this is a minority...

I take it from your SLI capable MoBo that you didn't have success in SLIing your 970s the normal way and had to resort to DSLIA to bypass nVidia's checks. Now that message about not having a bridge installed is quite common, even when a bridge is present.
I suspect it has to do with cards using different types/manufacturers of VRAM, even in the same card model.

I'd recommend to use a monitor program like nvidiaInspector and watch the bus load, on a second monitor if you have it.
If the bridge works properly, you see little bus load and GPU load should be evenly balanced among both cards.
In case of a non-functioning bridge, bus load will spike, depending on the application. If one of the PCIe slots is slower than the other (not the case with your MoBo, if you use the correct slots), this might also lead to asymmetrical load balance in this case.
It's a thing to keep an eye on over a couple of days...

Talking about PCIe bus: To keep bus load low, it's important to connect all monitors to the same card, if possible. Shared display space over different cards creates a significant bus load, even if it's only your desktop!

The problem I have is EVGA GTX 970 video cards. They created 3 different series of 970 cards & I have a gen 2 & a gen 3. I didn't know this until I decided to set up SLI & try some gaming & benching. I am usually just running Folding@Home & SLI needs to be disabled for both cards to fold properly. For some reason the EVGA 970's of different generations won't work together in SLI & I was hoping to find a way around their trickery. lol :) It looks like they are making it really hard to do.

I haven't been around here in a while, but I have learned on other forums that the more info I provide the better chance I have at finding a solution.
