USB 3 / SATA 6gbps on LGA 1156 Tags: Chipsets SATA USB3 Motherboards Last response: March 8, 2010 5:43 PM in Motherboards Share Kabobi March 7, 2010 1:54:51 PM I'm starting to put together plans for purchasing a new system, and at the moment I'm debating between 1366 and 1156. On the 1156, is it true that 1) Using USB 3 / SATA 6gbps will put all PCIE slots at 8x? and 2) that you cannot use both USB 3 and SATA 6gbps at the same time? I need to be able to use them both simultaneously and while I do not intend to SLI/Crossfire, I don't really want my single GPU to run at 8x. Could someone please clarify? Thanks. EDIT: perhaps I should add that when referring to USB 3 and SATA 6gbps I am talking about the controllers that come with the mobo, not the add in cards.

Kabobi March 8, 2010 5:38:41 PM Don't all current mobos use a NEC controller to provide USB 3 and SATA 6gbps support?
