I have experienced this with GTX 260's in SLI, GTX 285's in SLI, 2 GTX 295's in Quad SLI ( with 2 gtx 295s without a bridge I get the option to enable Multi gpu but if i do, it tries to enable both and causes a driver crash) and also GTX 470's in SLI. So it would seem that SLI without a SLI bridge in place isnt an option any longer.

So my question is do either one or both of you have a SLI bridge in place.

Thanks, that helped immensely. Seems like I'll have to wait until I get my bridge yessir.gif

Refer to my post #9 here (http://www.overclock.net/nvidia/918375-kfa2-gtx460-razor-review.html), GTX280 (not a weak card) was tested in SLI with and without a SLI bridge by TomsHardware as recent as August 2010. The motherboard was a Gigabyte P55A-UD7 and the OS was Win 7 Ultimate 32-bit with driver 197.45.

The trick is driver. Now as pointed out above by hodgoes2011, Nvidia has stopped supporting such a feature (ie SLI without a bridge) after certain driver (258.96).
So, if you really cannot wait any longer for your ordered bridge, try that driver.
When you do get it to work, run some tests and then rerun those tests again when your bridge arrives. I think, the comparison could be interesting.

I believe sli without bridge was used for low ends card like 8600 or something...

Evev if you can, I dont think running sli without bridge is a good idea.

yeah, thanks everyone, but I've decided to wait until my bridge comes.

I don't want to switch drivers because I get my best scores in 3DMark Vantage and 3Dmark 11 with the 260.99 drivers.

I tried the latest WHQL drivers and I scored awful.

A bridge is essential in high-end cards. The days that we couldve ran SLI without a bridge (7 series and other low-end ****) are OVER smile.gif
