Some have had to "extend" the desktop along with having monitors in both cards ... also the cards cannot be linked in SLI ...

You could try the 185.66 (beta). It should be a bit faster, if it works correctly on your GX2.

In my case (one monitor plugged) setting the SLI-mode in the driver option to no MultiGPU-mode was sufficient to activate the second "monitor", without rebooting or anything else. 185.65 (Beta), WinXP/32, manager 6.5.0 (23101).

Perhaps you need restarting the BOINC-manager.
