HyperSLI (Enabling SLI on non-sli motherboards)

[jbailey8]

Turning off testmode, will cancel out the modified driver, I don't know any way around this...

Once I compiled my own driver for peerblock, I even managed to sign it myself, that would
allow the driver to be installed into windows, but I still got the testmode text on my desktop.

Here's something that might let anyone change the colors of text on the desktop:

Can't guarantee it'll work, but it's a start.

Hello. I bought a computer of a friend some days ago and
I thought that why not buy another graphics card, which is
an Asus GTX 580 DirectCU ii. Now the problem is, I noticed
just yesterday that the motherboard (Asus P8Z68-V LX) does
not support SLI. I have been reading through the pages here
briefly, but if someone could just confirm if it will work to have 2 580
on this board using DifferentSLI?
Thanks!

 

[jbailey8]

It should work just fine, I'm running 2 560's (sli only) on a crossfire only pc with this modified driver. As long as the video boards your wanting to run in sli will support that mode
(most nvidia boards made in the last 10 years).

Be sure to read my post on this page:

No problem!

Hi! Trying to sli two gtx 660s on a crossfire motherboard. Having a problem though. I install everything exactly following the steps. First a clean install of the drivers, then put the patched file in the differentsli folder and run install. It says it's successful, then I reboot, only to find my graphics driver removed.

test mode is on, UAC is off, tried defaulting the bios, tried removing differentsli registries before installing again, hyperSLI is uninstalled (i tried it before differentSLI and it worked), anti virus is off. The cards are both connected and recognized and have an SLI bridge.

I just don't know what I'm doing wrong, man. Have any ideas?

Thanks a lot for helping us out!

 

[jbailey8]

Offhand, It sounds like test mode is actually off, despite what your saying in your post, your also the first person to have hypersli installed and differentsli worked better then, once you uninstall it, things get worse.
do you have any text in small letters in the lower right hand corner of your desktop that says the system is in test mode? If not, you can try entering this command in a administrator command prompt:

bcdedit /set TESTSIGNING ON

This should manually turn on test mode.

If this still doesn't fix the problem, then in your particular case, re-install hypersli since you stated it worked better then, also verify your installing nvidias' official driver 353.06 and the
patched driver has the same version number.

 

[Stoyan]

Sorry meant to say that hyperSLI by itself worked for me, not that differentSLI worked with it.

I do have the letters that say Test Mode in the lower right corner and I did try earlier by entering that command manually. Still no luck.

Last I've tried was with 352.86 driver and patched file.

 

[jbailey8]

My latest patched driver is **ONLY** for nvidia driver 353.06, if you try to install it with a different official driver (352.86 for example), it won't work, that's almost certainly the cause of your problem. Always check the version number in the download, you can't get them mixed up.

Here is the download link for the current patched driver, make sure you have installed
the latest nvidia driver from nvidias' site, it should be 353.06.

Hey guys, I recently bought two 970s but I realized my motherboard isn't sli compatible. Its a gigabyte GA-Z68A-d3-b3 (1 16x slot and 1 4x slot). If its possible, what do I have to do to get SLI working on my computer? I'd appreciate any helps/comments. Thanks

 

[jbailey8]

See my instructions here:
-------------------------------

*****If you have hypersli installed, run the hypersli installer and uninstall it and reboot your computer before proceeding!******

1. Go to http://www.geforce.com/drivers, select your operating system and video board in the list, download the driver installer.

2. Download my patched nvlddmkm35306.rar file here: http://www.gamefront.com/files/25037260/nvlddmkm35306.rar Uploaded 6/1/2015

*** NOTE *** always check back here on these forums for the current release version,
I will have the current version in the filename and when it was uploaded on any new
posts here. Also this driver is for 64 bit operating systems only! (windows 7 - windows 8.1
generally, this driver isn't for windows 10).

3. Go to https://github.com/EmberVulpix/DifferentSLIAuto/releases and download the 1.3 release file.

4. Unpack differentsli into a folder of your choice.

5. Unpack my patched nvlddmkm35306.rar file into the same folder where you put differentsli.

6. Install nvidia's official drivers (353.06).

7. Go back to where differentsli is installed, you might need to pause your anti-virus program too.

8. Open a command prompt (administrator version) and run the Install.cmd, it should say it was successful, if it says there was a problem, don't continue, post here as to what the error was. Unpause your anti-virus program.

9. Reboot your computer, once it's back up, go to your nvidia control panel and activate sli mode.

Please note, this patched driver is only for systems that don't otherwise support sli, my system only officially supports crossfire for example, but I'm running nvidia boards, not ati, so I have to install
my patched driver. Double check your motherboard specs, if your mb was made in the last few years, it might support both crossfire and sli, you just need to select which in your bios or mb switch.

The only other reason to use this patched driver is if you want to mix different model nvidia video boards and still have sli mode to some degree. Please note the video bd has to
be 'new' enough to support sli, nearly every nvidia board made in the last 10 years should
be able to handle sli mode, a dead give away is if the bd in question has a sli bridge
connector on it.

Very important! make sure that the nvidia driver your downloading and the patched driver
your downloading matches in the version numbers, I'll always put for what version my
patched driver file is for in the download link, don't get them mixed up...

I hope my explanation helps.

Have fun!

@jbailey8 thanks for your reply, it worked! I can enable SLI now. However, whenever I play a game the fps drops to lower than half of what I would have with 1 card and then the monitor says "out of range" and the computer shuts off. Whats the cause of this and how can I fix it? Thanks

 

[jbailey8]

It sounds like the refresh rate is either too high or too low, try going to 'control panel' then 'adjust screen resolution' then 'advanced settings' then click on the 'monitor' tab, you should see a
selection box where you can adjust your refresh rate, also while your in the adjust resolution window, set your default resolution, in your case I'd select something basic like
1024x768, set your refresh rate to 60hz, you can always set your resolution back to what it normally would be (probably 1920x1080), but we are just trying to get some video on
the monitor for now. You might also try putting the monitor cable on the other video board
too if none of the above works.

At the time I used the proper patched file.

But I have good news, it worked! Not exactly sure what did it, but I removed ALL registries of differentSLI before reinstalling it this time, I seem to have missed some in the past. I also swapped the graphics cards. Did those things and the latest driver is now running in sli.
Thanks a lot for your replies.

 

[jbailey8]

Too Stoyan -- Glad you got it going!

 

[jbailey8]

To Bilal -- make sure you have a sli bridge connected to both video boards and it is seated properly...

 

[Bilal]

@jbailey8 I had my refresh rate at 144 Hz and resolution @ 1920x1080. I decreased it to 60 and 1024x768 as you suggested, same thing happened. Then i tried connecting the monitor to the second card and it shut off again. Any other solutions? Im not too experienced with computers. I could maybe try another sli bridge

 

[jbailey8]

Make sure your sli bridge is the right one for your boards, but there are only 2 basic bridges, 1 for crossfire (ati boards) and 1 for sli (nvidia boards), as long as your sure it's not for crossfire, it should be ok.
also while in the bios, make sure it's set for single display and not multi (I assuming your running only 1 monitor), check to make sure that crossfire doesn't need to be manually enabled in the bios.

See here for specs on your motherboard:

[jbailey8]

Please note that this patched driver is for 64 bit operating systems only! (windows 7 64 bit - windows 8.1 64 bit generally), do you see in small white text on the lower right-hand corner of your desktop
anything that reads 'test mode'? you didn't specify your operating system if it's too old and/or 32 bit, this driver won't work.

The only 32 bit video drivers I saw on nvidias' site were old outdated betas.

 

[jbailey8]

I need to clarify one other thing, Embervulpix is the author of the patching program, not me, I'm simply running his patcher on my driver and uploading it for those who are having trouble
running the patching program themselves, and I'm trying to provide what little support I can to help those on here that have questions, however I wouldn't mind learning how to maintain the
patching code if ember decides at some point to quit maintaining it for some reason later on.

 

[meinelol]

Hello guys,

I can't download the patched file : nvlddmkm35306.rar

I got an error : file not found. Is it possible to provide an other link ?

Thx and good job

 

[leonardofabi]

Quote as above.

Download is broken.

Best regards

 

[jbailey8]

I just tested my download link and it worked perfectly for me, if your error doesn't clear up in a few hours, let me know and I'll repost my file somewhere else.

 

[leonardofabi]

Tried right now, still not working mate...
