[Solved] Dual gigabyte gtx 260 oc on asus p6tse help

No - the P6T SE only supports Cross fire and not SLI. If you want to run dual graphics cards on this mobo you need to swapp the nvidia based cards for ATI chips.

Either that or swap the mobo to the P6T instead

there are some posts out there that claim to have a solution to make SLI work on chipsets not originally intended to run multi nvidia set ups.
I remember reading a few months back on Custom PC that despite everyone thinking it was a hardware issue, it turns out Nvidia rely on a piece of sftware to make SLI work.

Now both the P6T and P6TSE have the same chipset so in theory it should be possible.

If I can come across the original post on how to "force" sli on non SLI boartds I will post the link

Excellent !

Thank you Ulysses that post gives clear instructions as well.

I am expecting delivery of all parts in the next couple of days and will post back to see how I went !

In my past experiences the mobo manufacturer usually includes a bridge in the box - either that or the video card usually comes with one..

Success
I flashed the p6t se with the p6t bios
installed the second gtx 260 and the sli bridge
enabled sli and all is working well

3D Mark vantage score went from 14,000 ( approx) to 24,133 with sli

Thanks for the help Ulysses

much appreciated
