HOWTO: SLI on a non-SLI Motherboard (GTX5xx compatible 1.0 final released!)
I can't find an official thread (if there is one, link to it and I'll delete this one, I did UTFSE), but I'm wondering if anyone out there is using this setup since the guide had been posted.
The install is simple: Install the latest drivers, run the patch and SLI option should appear in nVidia control panel.

Modded drivers for use with beta version 1.5 (download drivers, copy files into driver setup directory, install driver, run patch): DOWNLOAD HERE
Current Common Chipset Support
AMD 7xx and 8xx
Intel P45, X48 and X58
Chipsets Confirmed NOT Working
P55 (May work with drivers 190.xx but not newer drivers)
EXPERIMENTAL but recommended instead of SLI patch!: HyperSLI
Designed to work on ALL chipsets and motherboards with two PCI-e slots!
1. Download and install nVidia drivers
HyperSLI support thread: http://www.techpowerup.com/forums/sh....php?p=2414995
NOTE: The patch does not work with Avast antivirus installed because the antivirus will not allow manipulation of Hal.dll. If you try to use the patch with Avast installed, blue screens will result.
|Originally, SLI-capability of motherboard checked by complex crypted routines in videocard driver, and thus bypassing this check was quite hard earlier. There only few old drivers present, which support SLI on non-NVIDIA chipsets, like 84.xx and 81.xx drivers made few years earlier. Now things changed, with officially SLI-capable Intel X58 chipset. In the case of Intel X58 motherboards, checking SLI support by driver was developed with a simplified scheme, which uses text strings and identifiers for all present and future X58-boards. Later P55 are also was added to support similar SLI certification procedure.
Modification tools described here can be used to force the NVIDIA graphics driver to detect supported chipset Â«Intel X58Â», regardless of what the real hardware chipset present in system. After receiving the identification of a "X58" chipset, videocard driver checks for the correct certificate from BIOS to check "compatibility" with SLI tech, which should be located in the system table DSDT, which is a part of ACPI. Initially, the data tables are loaded from the computer's BIOS, but later, if BIOS wasn't changed, used from the regular OS registry entry by Windows.
For today, after long time of tool development and research, we got latest version of patch available in beta-status for public testing. These modifications are for education purposes and are provided "AS IS", without any warranties. We (xDevs.com project and developers of SLI patch) cannot be held responsible for any errors, failures or data loss during this procedure, make sure you have backed up all critical data before trying this mod. So, before we give all instructions, please note that these operations interact with the PC's hardware at low level, so in case your PC fails, data loss or any other damage occur responsibility rests solely on you. . However, on all the systems we have tried, we have had no errors, all passed without any major mistakes.
Because of difference of OS kernels and HAL library in every os, every SLIpatch tool hardcoded and dedicated only for specific operating system type and version. Using wrong SLIpatch will cause OS unstable or even damaged. Be aware to use only proper tool version.
This method and tools has been successfully tested and implemented for following operating systems:
Microsoft Windows XP 32-bit
Microsoft Windows XP 64-bit
Microsoft Windows Vista 32-bit
Microsoft Windows Vista 64-bit
Microsoft Windows 7 32-bit

Answers to common problems reported here:
Q: Why SLI setup isn't faster than single card in Windows Vista?
A: Due the error in Vista second card is not used in DirectX applications. Install system update SP1 and Forceware driver >162.18 to fix this. Also, you can not SLI dissimilar cards (for instance, a GTX 460 and a GTX 470).
Q: Do I need SLI bridge? Can I use Crossfire bridges? Can I run SLI without bridge?
A:SLI bridge for MIO interface on card helps cards to transfer data between GPU's without need to use computer PCI-Express interface. Bandwidth of this MIO interface is close to PCI-Express x1. SLI Bridge isn't critical for SLI operation for two single-GPU cards but it helps to lower PCI-Express loading. In simple words FPS in games and tests will be better with SLI bridge. For complex SLI systems, like 3-way SLI or Quad SLI presence of SLI-bridges is essential.
Crossfire bridge cannot be used with NVIDIA cards, the have different pitch, contact amount and configuration. You will damage card trying to use ATI Bridges on NVIDIA cards.
SLI bridge is now required for drivers over version 2xx.xx and SLI will not work if you do not have one.
Q: I made all steps for my OS, but SLI don't appear, or my OS is crashed and don't boot anymore! Help me please!
A: Recheck everything, just a single mistake can render your OS unusable. Try pressing F8 and selecting "Load last good state" or "Disable automatic reboot when failure", it can help you to boot flawed system. If you are sure that everything was done correct, and still have problems - send mail to our support address support"signofmail"xdevs.com with your DSDT table (received by tool with key iasl -g, and detailed system configuration and problem description). We will try to respond as soon as we can, but remember, this is free project, maintained only when there is free time, so be patient to wait some time.
Additionally, if SLI option does not show up, try uninstalling the patch, setting the BIOS options to their defaults, then reinstalling the patch.
Q:Will this mod work on my ASUS XXX-XXX / Gigabyte YYY-YYY / Vendor Z model AAA-BBB-CCC motherboard to get SLI?
A: We don't give any 100% guarantee, but as far almost all motherboards which have two PCI-Express slots can do SLI. Only correct ID reports to videodriver and physical ability to drive all videocards from single hub/complex is necessary to make SLI technology enabled. There are some rare cases, when even mod from this article wouldn't help, by we have no such cases yet.
ive already tried it on an AM2+ board (Gigabyte GA-MA790X-UD4P) and it actually works though the AM2+ system was not mine.. it was a friend's system.. which means its not actually hardware locked.. its software locked..
its much easier to do if your using Windows 7 OS instead of XP..

I think you should duct a leaf blower onto your air cooler...wait till liek 2am and fire it up for some hardcore OC action ..really piss of the neighbors.. and see if you can F5 your CPU-Z before the cops show up!!
Do the opposite of what this guy just said if you want the best results you can get
