I just got my second card :(

[LaRZ]

I just got my second card but I cant set any sli mode.

I have a Lanparty NF4 SLI-DR with two 7800 gtx Leadtek cards and I put the SLi bridge on and booted up the system. It detetected the second 7800 gtx in windows and appears next to the other in device manager. but when I go to set SLI mode under the Nvidia Control panel there are no options, it just says add a second gfx card still. I reinstalled the lastest drivers. and for a while I couldn't see the SLI option in the CP anywhere.

In the Bios My PCIX settings are x2 NC x16 x1, is this correct ?

any help muchly apprciated.

I believe you want 8x and 8x rather than 16x and 1x.
there might also be a jumper on your board which you have to switch to enable Sli.

Yeah, there's a jumper you need to switch over.
PDF manual

Click on the 'Sli Technology' link on the left hand side or scroll down to page 67.
It continues on for a few pages, but details everything that you need to know.

just looked on the DFI site for your mobo and you do indeed need to set sli mode to 8x 8x = x16 when using to cards

mainboard sli jumpers moved to sli mode?

if there is an option the bios to go to 2*8x slot select that as well.
