HyperSLI (Enabling SLI on non-sli motherboards)

[jbailey8]

I checked the specs for your motherboard, see here:

http://us.msi.com/product/motherboard/Z77AG41.html#hero-overview

It has a built-in video port, I strongly suspect that the on-board video chip is active and interfering with the other 2 boards and/or the patched driver, there must be a option
somewhere in the bios to disable the on-board video chip. I had to disable the on-board video chip on my motherboard before the driver would work on my system.

Another thing to consider is that you need to have only 1 monitor connected, use the stronger video board as your display board and see if that helps. Once things are up and running then
try re-connecting your other monitor.

I checked again in bios, and the only thing i found worth mention is i can change if i want to go with "Peg" or the other one for onboard... It was already on "Peg" so i left it.

I'll try out things with just one monitor connected.
->same thing as with two monitors..when i activate "max 3d performance" driver crashes..

 

[jbailey8]

I wish you could swap your video boards around but that's not a option in this case, you can try connecting a monitor to the other video board and try that, if that doesn't work I would be wondering
if 1 of your video boards is actually bad in some way, did you check the event viewer to see what errors are listed?
Also be sure your running the right version video driver for your operating system and that
you ran the same version official installer first.

 

[SooFar]

No, I dindn't check it yet.. I'm currently installing driver "359.06" again, and when it is finished, i try doing it with the monitor connected to the gtx660. Do I have to check the eventviewer after the driver crashes, or bevor i reboot my system?

I think it either won't work because i do kind of a workaround, because i manually paste the "nvlddmkm.sys" into the drivers folder, because the patcher doesn't get it there.
Or it is not working, because the 3 numbers after the "dev.." code don't match..

I don't think any of these boards are bad, because both run fine, if i'm yousing them 'normal'

I checked it now, but i don't have a clue what it means , many warnings, and some faults

After activating sli with connected 660 i dont get any signal anymore..

 

[jbailey8]

Are you trying to install a already patched driver or are you running the exe on the official driver? If your trying to run the exe on on a already patched driver the results could be unpredictable.

 

[SooFar]

I use an official nvidia driver, copy the "nvlddmkm.sys" to the differentsliauto folder, patch it, let the install.cmd run, copy the the "nvlddmkm.sys" of my differentsliauto folder and paste it instead of the "normal" one in the drivers folder, and run the install.cmd again. Running fine after rebooting, but if i want to activate the now showing up sli Option, the driver crashes and Needs to be reinstalled..

 

[jbailey8]

Do everything you just stated again except don't run the Install.cmd a second time, It only needs to run once (generally), this signs the driver and tries to copy it over, just do a manual copy like you've been doing.
Reboot again and see what happens when activating sli mode.

 

[SooFar]

Did the same again and run "install.cmd" just one time after patching "nvlddmkm.sys". When I try to enable sli it crashed again..

 

[jbailey8]

After you install the patched driver, reboot your computer again, but don't try to activate sli mode, go to the device manager and see if there are any "X" or "!" next to the icons that represent your video boards.

Also turn off uac, and do you see any text on your desktop in the lower right-hand corner
that says "test mode" and some build number?

 

[SooFar]

Yes, Testmode is activated. And i'll look tomorow if there Are any x or !.. Do you have any clue what could be the Problem? In the thread where i downloaded sliauto, it said that First 3 numbers After "dev" have to match, that it could work.. Mine dont match, but i think i mentioned that in my First Post..

 

[jbailey8]

The dev numbers not matching could be causing a problem, the only other thing I can think of is uac is turned up too high, beyond that, I'm not sure.

 

[SooFar]

I turned uac off (pulled the bar completly to the bottom..)

 

[jbailey8]

I checked the dev numbers for my video boards, they are both "1201", for the dev numbers not matching to be a problem is a little rare based on my experience, if there are no "X" or "!" next to the video board
icons in the device manager and you have the text "test mode {build number}" on the desktop after a reboot, and uac is off, then the driver installed properly and is trying to run, the only thing left I can think of is the
dev numbers not matching as the cause of the problem, the only solution is to find another board with the right dev number and try that. If you could swap your boards around you could see if that helps, I usually get people up and running, your the first one in a while where I
failed at that, if I think of anything else to suggest, I'll post here.

 

[SooFar]

Maybe i can change boards with a friend of mine. It's exactly the same card (msi gtx 660 oc). Should also work better and have more Power that 660&760 i think.. I'll tell you the latest news when there are new ones.

 

[jbailey8]

Ok, Good luck!

 

[SooFar]

So, changed cards with my friend, now running two msi gtx 660 oc absolutely fine.

I really have to say thank you to you jbailey8 .

 

[jbailey8]

Glad everything is working! So it was the dev numbers being different...

 

[jbailey8]

I ran accross this late last night:

http://www.softpedia.com/progDownload/NVIDIA-BIOS-Editor-Download-4977.html

It's a utility that lets you hack the bios on your video board, in theory at least, you could change the dev numbers (don't know this for sure) and other things on your video board, but I hesitated to
mention this because it would be too easy to make a mistake and turn your video board into a brick.
If someone wants to mess around with this utility, feel free, but you do so at your own risk!

Edit: According to this youtube video:

You can actually change the dev numbers on your video board to what ever you want.

Hello, friends and overlockers.
I have this system
ASRock Z77 OC Formula, i7 3770K, RAM 2*8gb,
2gb GTX 460 SE and GTX 460 SE 1gb plus sli bridge.
After installing differentsliauto and doing all the manipulations in the nvidia control panel has the option of sli (that is good) but after it appears a black screen, hard reboot and crashes the graphics driver. The nvidia driver 359.06.
Please help.

Sorry, I use Win7pro

To Jackal:

If your running windows 10, make sure there are no signing errors listed in the output of the Install.cmd, and that the driver actually got copied over properly, assuming that these 2 things aren't the problem,
your dev numbers are probably different between the 2 video boards, see the above post (#3018) on how to possibly solve this issue.

I use win7x64
My both card:
PCI\VEN_10DE&DEV_0E22&SUBSYS_080110B0&REV_A1
PCI\VEN_10DE&DEV_0E22&SUBSYS_080110B0&REV_A1

How it possible? I find this table

[*]DEV_0E22 "NVIDIA GeForce GTX 460"
[*]DEV_0E23 "NVIDIA GeForce GTX 460 SE" (this is my card)
[*]DEV_0E24 "NVIDIA GeForce GTX 460 "

When I start NiBiTor and go to `read BIOS` going error "Cant start driver:577"

Hey, I am really loving being able to run SLI on my old motherboard but I was curious. Can I update my motherboard drivers normally or will that affect the sli program in any way?

 

[jbailey8]

To Joe Sizzle:

You should be able to update your other drivers just fine, the only driver that the patched video driver is concerned about is video related.

 

[LoWRiDeR82]

Hi Guys, I would really appreciate it if someone could post working links for both the latest hypersli as well as differentsli as I just built an HTPC game station with old pieces and would like to activate SLI on it.

Any help is greatly appreciated
