Windows 7: Dual GTS 450's in SLi. Option does NOT appear in nVidia Control Panel.

Dual GTS 450's in SLi. Option does NOT appear in nVidia Control Panel.

Hi, A few days ago, I made a small purchase.
I bought 2x ZOTAC nVidia GTS 450's and a SLi Bridge connector.

I've read around that the SLi enable option should be available under the 3D section, with the PhysX configuration, but it's just simply NOT there.

Even GPU-Z says that SLi is disabled!

The video cards are installed, I disabled my onboard video from my Motherboard Bios.
But still, it does not let me SLi those bad boys to squeeze max performance out of my pc.

What should I do?

For starters you cannot run SLI on an AMD chipset, you need a motherboard with a Nvidia chipset. Short of replacing your motherboard or running a single card, there isn't much you can do other than returning the cards and going with a single card or getting two AMD cards to run in Crossfire if you want dual cards.

Personally I would return them and go with a single card. For what you paid for those two (or at least the price on Newegg at the moment) you could have got a GTX 470 or HD 6950, either of which performs about the same (or a bit faster in some cases) as 2 GTS 450's in SLI.
