So I'm the sad owner of a Dell M17xR3 that hasn't had a driver update since 2010. I was managing with this for years and yesterday decided to use a modded nvidia driver (vs. 340.52) on my 280Ms.
Now, SLI is disabled and I can't seem to enable it....system is defaulting the to the integrated graphics (9400) and I can't make it even use a single 280M, let alone both.
Both of the 280M's are registering in the Device Manager as well as the Nvidia Control Panel, but I can't access them. The message says "SLI disabled" and will not change to the 280M's even when I click the "Maximize 3D performance. The system is running Windows 7 Ulitmate and is completely updated.
I have gone through several clean installs, enabled and disabled the hybrid graphics in the bios as well as enabled/disabled the PCI/Gen 2 option there as well - all of this to no avail.
Suggestions?
