A while back Asrock published a SLI enabling patch for their ULi chipset based motherboards that have two PCI-Express slots. Various rumors suggested that the patch would also function under other chipsets as well, and allow users with other chipsets to use SLI on their non-SLI motherboards. Unfortunately the original version of the patch installs only on ULi 1695/7 chipsets - you couldn’t use it if you didn’t have a motherboard with that particular chipset.
We’ve managed to rip the installer and to create a modified version of the SLI patch that allows you to use it with EVERY motherboard. We couldn’t do in-depth testing on other chipsets, but if the rumors are true then it should definitely work. Feel free to use it at your own risk, and please post the results in our forums. Remember, this is a modified version and is not supported by Asrock, ULi or Nvidia..
