Closed How about the third PCI-e x 16 Tags: Graphics Cards Motherboards PCI Express Graphics Last response: October 12, 2012 4:32 PM in Graphics & Displays Share kdy77k October 8, 2012 8:39:40 AM I found that a lot of mother boards based on Z77 contain third PCIe 16x. According to the Ivy-bridge CPU's specification, Z77 supports 3-way graphic card (8+4+4). I have some questions: 1) If it just plugs a graphic card on the third PCIe x16, what the bandwidth of the graphic card in Max. ? x4 or x16? I find that some Asus's motherboards just support PCIe2.0X16 on the third PCIe lane, how about plug a single graphic card on this lane? 2) If the third PCIe lane just support PCIe X4 at Max. , why the lane is full-length (x16)? 3)If I plug a Graphic card on the first lane and a Video capturing card on the third lane, how the about the bandwidth of the two devices? 4)I am DV fan(not crazy fan) and play the video game (ex: battle field3 ) sometimes (not enthusiast). Whether I need a motherboard which support 3 PCIe X16 lanes? 5) Please recommend some devices which need PCIe X4 even PCIe X16 lane Thx More about : pci kdy77k October 12, 2012 5:39:06 AM Who can answer the question?
