HyperSLI: Enable SLI on a Crossfire-Only Motherboard

I built my computer a little over two years ago. At the time, NVIDIA (a GPU manufacturer) and Intel (a CPU manufacturer) were at odds with their licensing agreements, and I ended up being stuck with a Crossfire-only motherboard. If I wanted to use multiple graphics cards in parallel, they had to be ATI cards. Nevertheless, I purchased an NVIDIA GTX280 card because it seemed like the best card for the price. Lo and behold, earlier this year I completely forgot my motherboard was Crossfire-only and I bought a second GTX280 in anticipation for new games such as Battlefield 3. That was basically a $200 mistake.

Fortunately, a lot of other people also wanted SLI on their Crossfire-only boards, and someone created SLIpatch.  SLIpatch is great, but it has a few shortcomings such as requiring modified NVIDIA drivers for each driver revision. A few days ago the developer released a new tool called HyperSLI, which greatly simplifies the process and doesn’t require modified drivers. HyperSLI currently only works for motherboards with Intel processors, so if you have an AMD processor, you’ll have to stick with SLIpatch [Edit: Now works with AMD chipsets] . But if you do meet the requirements, here’s how to make it work:

  1. Install the latest NVIDIA drivers for your card.
  2. If you’re upgrading from SLIpatch to HyperSLI, just run the HyperSLI installer and click “Update”. If otherwise, just click “Install”. Simple.
  3. When the computer is rebooting, open up the BIOS. Most computers use either F1, F2, or DEL to access the BIOS. Look for something called “Virtualization Technology” and make sure it is enabled.
  4. When the computer boots back up, open up the NVIDIA Control Panel and enable SLI.
That’s it. Pretty easy.

  1. HyperSlI has improved. I’m using it on my AMD 1100t 6core cpu and a MSI 890FXA-GD70 motherboard with 2 GTX 480’s. I had to reset my BIOS for some reason, and reinstall the latest v295 nvidia drivers, but all is good now, and BF3 rocks!

  2. im sorry to say but it works just fine with amd, you need to read into the facts some more, or quit being an intel fan boy….and if you were smart you would know that crossfire is for amd only and intel is sli

  3. Mr Dudeson,
    Not sure if you are just trolling, but at the time of me writing this article, HyperSLI only worked with Intel chipsets as HyperSLI required Intel Virtualization Technology. I did say CURRENTLY for a reason, and I suggest you adjust your reading comprehension skills to account for something called “time”. This may be hard to grasp but “current” things become “past” things as time moves forward. You’ll figure it out I am sure of it :)

    Not sure what you’re trying to say with your last sentence; a few years ago intel and NVIDIA were unable to reach an agreement and many boards with Intel chipsets were exclusively Crossfire. Again, I suggest you look into that whole “time” thing. I have the utmost faith in you.

  4. lol, owned (it was only a matter of time).

    Haters gonna hate, they just don’t realize it makes them look like the fan boy instead. Even if you were wrong (which of course you weren’t at the time of writing), you weren’t coming off as an amd hater so I’m not sure why all the sensitivity.

    Good article, btw. I too thought I was toast when I bought a second 560 ti recently for my aging x-fire board. Now that this article pointed me to this hack I am running 2 560s on an Asus P5Q Premium, quite smoothly.

    Thanks.

  5. I have read about AMD board officially supporting Crossfire but I have already bought GTS450 so I don’t to buy 2 AMD gpu just for Cfx. Been frantically looking for a way to enable me to use SLI on my Crossfire only Mobo and good that I found your page.

    Thank you
