How To: Enable SLI on pre-i7/i5 hardware

Any good news/step forward in v195.62 drivers work ??? (either with modded HAL or directly modded drivers?)

What CPU do you use? If Xeon, try with some generic Core CPU. Just for test, to be sure on this

It's being worked on, but I've been low on time lately. I'm doing what I can. Worst case scenario, I've got 9 days off coming up at the end of the month.
 
We are working on 195 drivers.

Still no much success yet, but we have next ideas to try.

I got 2 8800GT's in SLI on my P4 661 with a 915chipset :laugh: thats one big ass bottleneck

LOL. what exact mobo?
 
i keep working. they did check for patches.

OK, keep on this AWESOME work!! You're doing great!

In case you wanna include another succesful one:
I got SLI working with 2x8800GT on an Asus P5K Premium/WiFi-AP (Intel P35 chipset), under Vista x64 (modded 190.62 drivers) and Windows 7 x64 (modded HAL & original 191.07 drivers)
 
I figured I would add yet another datapoint:

Asus Crosshair III Formula (790FX chipset)
Dual GTX280s
Windows 7 x64
HAL mod
191.07 drivers
-Works great

Upgraded to 195.xx WHQL drivers, no SLI. Decided to run with only 1 card, video would drop out completely (black screen) and lock the system. Uninstalled the extra GTX280, still 195.xx WHQL drivers and would still get black screens and lockups. Uninstalled 195.xx WHQL drivers, reinstalled 191.07s, system is stable, runs great.

Obviously they are not only doing extra checks for 195.xx WHQL drivers, but they are also causing problems if they do find things patched. I did not undo the HAL mod to see if 195.xx WHQL drivers would work or not without it.

I was originally running a Foxconn Destroyer (nvidia 780a chipset) with a 9950BE along with the dual GTX280s. But, I decided to setup a machine for my oldest daughter that would server double-duty as a server, so the motherboard/processor/memory and a 9800GTX I had sitting around went into her setup and I upgraded to a Asus Crosshair III Formula with a X4 955 and DDR3 RAM because I got a hell of a deal on everything, but really the major reason I decided it was doable was because of the SLI hack due to my dual GTX280s.

The new setup runs flawlessly with the 191.07 drivers and I really hope you guys figure out how to get even newer ones running.

I just can't believe that nVidia doesn't offer a consumer level 'upgrade' where we as consumers could buy a nVidia SLI certificate/certification for our motherboards. Hell, I believe the cost I heard for x58 motherboard producers was $5 per board for certifying them, so why not offer the same to consumers for $7-10 for whatever system they want to run under SLI?

Now I do understand that some system may not be 100% compatible, and nVidia probably doesn't want to get into the testing/certification market because of that, but why not offer it on a 'development' basis for those of use that want to 'take the risk'? (well, outside of the OBVIOUS, and probably biggest reason they don't, and that being all the idiots that can barely put there system together, let alone configure a system to run a setup it wasn't intended/certified for, as I am certian they would be inundated with support calls/problems... Hell, I wouldn't doubt this hack alone hasn't generated some increased tech-support for some vendors)
 
here is some proof that i got it to work on the old 915 chipset

Okay so I got hold of another 7950GT and I have an SLi bridge ready

I have one question though...

The only 6 pin PCI-E connector I could get hold of only has 3 wires going into it, and 3 metal pins, even though it is a 6 pin socket design, therefore it still fits onto the card...

Will this work? Cos it worked for my X850XT and that had a 6 pin socket

If so, I'll set up my SLi on this ASUS P5W DH Deluxe (i975x chipset) and let people know how it goes :)
 
Yea... drivers just say they're installed but say "The system has not been modified. Please run the installation again to complete setup" and it says that every time (of course, I'm referring to the modified drivers on this page: http://xdevs.com/e107_plugins/content/content.php?content.30 )

I've installed the SLICString and that is okay, but the drivers won't install :|

Why?

EDIT: It won't even let me install normal original drivers either, I'm guessing it's cos I have this other card in...

Obviously it knows that and won't let me install drivers :/

Is there anybody who can help me get SLi working?
 
If it have +12V and GND + GND for sense i should work, but I suggest you to change your PSU to better one
 
Lack of data to help
 
195.62 has been cracked and is running on my P45 board. I will not be releasing details or drivers until we are sure on how we want to release this. I'd like to make it less confusing this time. I will be talking with anatolymik to figure out if he can properly implement this without running a modified unsigned driver.

Wow great news!

If you need a tester, you know I'm here & willing to do so.

Running a modified unsigned driver is fine with me.

n1, so glad to se fellow p45 members with sli :)
 
nice to see this working on alot of chipsets... I almost want to grab a 2nd 7900GS to see how 2 voltmodded 7900GS would do in SLI on a X2 240 when i get it :laugh:
 
Just tested with 3D Mark 06

My score went from 5000 with SLi disabled to 8000 with SLi enabled, and it was a lot smoother in the animation sequences (obviously lol)

Loving it :)
 
Great work guy's! Glad I found this forum. I got it working with method 1 and 2 from the http://xdevs.com/e107_plugins/content/content.php?content.30 website. However its not working stable. Some game's (battlefield 2142, left 4 dead) crash the pc after few minutes of game play and the computer just restarts. I can't finish 3d mark 06 benchmark without it restarting the system :( It works fine in Section-8 and FFOW though :) Maybe I'm doing it wrong but I can enable sli in nv control panel and gpu-z shows 2 gpu cores. Same results with both methods.

EVGA 8800 gts 512mb x2 w/bridge
190.62 nvidia
Windows 7 Ultimate 64bit
ASRock P45X3 Deluxe (P45 chipset)
Xeon 3060
2 gig DDR3
silverstone 600 watt sli ready

Are you overclocking your CPU or video cards?
If OC of CPU, you may have to add extra voltage to stabilize the system.
 
you may need to add alittle voltage to the chipset and are you sure the PSU can handle it? One last thing the 191 drivers work great
