SLI PCI-E Tags: Nvidia SLI PCI Express Graphics Last response: August 22, 2011 11:08 PM in Graphics & Displays Share STOPOT August 22, 2011 10:15:09 PM Hey, I have 1 PCI-E 16 at 16x and 1 PCI-E 16 at 8x, and my mobo is rated for SLI. I was wondering how? Don't I need 2 PCI-E 16 at 16x to do SLI, and if I can do it with a 16x and 8x slot, will it impact performance of SLI configuration?
