SLI not working Tags: Nvidia SLI Devices Graphics Last response: January 4, 2012 5:31 PM in Graphics & Displays Share SothemX June 7, 2011 1:08:08 AM I ran a diagnostic with SiSoft and it said that "no PCIe device was detected" !? Yet I have two GTX460 cards installed. This could be why SLI is not working but how could that be possible? could PCIe actually be disabled?
