Need help - SLI setup

[Jase]

I've just built a machine with 2 x 8800 Ultras (on an Asus Striker Extreme MB) with XP Pro SP2.

I've installed Forceware 169.21 drivers but couldn't see any options for SLI. I checked device manager and under Display adapters only 1 card was showing.

I just got off the phone to OcUK tech support who advise that only one card will be shown in the device manager/Display adapters but both will be shown on the Nvidia panel with an option to enable SLI somewhere.

I don't know my way around the new Nvidia Control panel at all (seems more confusing than the old one), but I've searched and can see no reference to SLI.

Can someone point me in the right direction or give me an 'idiots guide' to setting it up as I've no idea whether it is working or not

Thanks

Jase

Thanks for the reply.. I'm using Windows XP Pro SP2 (I'll edit origial post now)...

I can not see any mention of SLI in the 3D settings page, it's not really I tab that I see its a list as below :

- 3D Settings
- Adjust image settings with Preview
- Manage 3D Settings
- Monitor temperature levels

- Display
etc

The cards were in the two blue PCI-E slots, the ones furthest apart. I've just moved one to the slot closest to the main one though to try but still the same.

I'm using a Coolermaster Real Power 1000w Modular Power Supply

I dont see the option "Set multi-GPU Acceleration" in the list

I thought it was strange that only 1 card was showing in the Device Manager but I was told it definetly only appears as one by Tech support.

Is there anything in the BIOS or MB I should be checking ? I had a look in the BIOS and couldn't see anything. I checked PCI-Express Broadcast Aperture to "Auto" was set as I read somewhere.

Thanks in advance for the help
