The the list of update in chipsets seventh series include the interface PCI Express 3.0 - Panther Point support all the same eight PCI Express 2.0, as their predecessors.
The performance of third PCI Express x16 slots on many motherboards based on chipset Intel Z77, will depend on the type of processor. In this expansion slot, which runs no faster than mode PCI Express x4, there are even special warning labels:
To use this slot for other purposes, you must install socket LGA 1155 processor generation Ivy Bridge. PCI Express controller of these processors allows for sharing of resources between the three devices (upper diagram), whereas its predecessor was limited to only two devices (lower diagram).
When we use all three slots, they work according to x8 + x4 + x4. Since we are talking about the interface PCI Express 3.0, the bandwidth is sufficient to maintain a bunch of three cards. This arrangement allows motherboard manufacturers to save the line PCI Express 2.0, which manages the chipset. Related Products :
