Tags: Asus Motherboards Last response: June 4, 2012 6:47 PM in Motherboards Share venur June 4, 2012 4:39:27 PM Bought a new rig (spec on signature) and have a lot of problem with GPU (now it won,t even recognise it) Been told to switch the pcie 3.0 to 2.0 in the BIOS (it seems it has worked for many user of the p8z77), but I can,t find how to do it.

Besides your 670's are 3.0, not sure why you would want 2.0. If it's possible it will be in your manual. | Report abuse rolli59 Motherboard Master June 4, 2012 6:47:45 PM It should be automatic, it will just default to the speed of the installed hardware. | Report abuse Ask the community Publish Tom's Hardware>Forum>Motherboards>How can I set PCIE 2.0 instead 3.0 on p8z77 WS ?> Related ressources: ForumASUS Rampage IV Extreme PCI-E 3.0 Support ForumSabertooth vs P8Z77 Deluxe (Features that matter) ForumWhy should i get PCI-E x16 3.0 motherboard instead of 2.0 ?
