Closely trailing the GA-X58A-UD7, Gigabyte is preparing a new high-end socket LGA-1156 motherboard based on the Intel P55 chipset. The GA-P55A-UD7 is touted to lead the new pack of motherboards under the P55A series, which bring technologies such as USB 3.0 and SATA 6 Gb/s integrated for the LGA-1156 platform. Observantly, after a very long time, Gigabyte has made use of an NVIDIA nForce chip on its high-end motherboards, certainly the first time it has made use of the nForce 200 PCI-Express bridge chip. Gigabyte made some clever use of its real-estate, especially with regards to the PCI-Express bandwidth.
The LGA-1156 socket is powered by a 24+3 phase circuit. It connects to four DDR3 DIMM slots for dual-channel memory. Its PCI-Express 2.0 x16 link is wired to an NVIDIA nForce 200 chip, which gives out 32 PCI-Express 2.0 lanes to ensure support for 3-way NVIDIA SLI, ATI CrossFireX is naturally supported. There are three PCI-Express x16 slots (which arrange into x16, x16, NC; or x16, x8, x8, depending on how they're populated). A PLX-made PCI-Express bridge chip (probably connected to the PCH) ensures full-bandwidth PCI-Express 2.0 x1 connections to the NEC two port USB 3.0 controller, and the two port SATA 6 Gb/s controller made by Marvell. Apart from the six (color-coded blue) SATA 3 Gb/s ports the PCH provides, the two color-coded white ports on the south are SATA 6 Gb/s, while the two on the north are connected to a Gigabyte GSATA2 SATA 3 Gb/s controller, which also gives out an IDE connector.
Other expansion slots include two PCI-E x1, and two PCI. Connectivity options include two color-coded blue USB 3.0 ports, several USB 2.0 ports, Firewire, two gigabit Ethernet interfaces, and 8-channel HD Audio with optical and coaxial SPDIF outputs. Apart from large heatsinks that cover the CPU VRM and PCH, a water-block cools the area which covers the two PCI-Express bridge chips, south of the CPU socket. This board should carry some of Gigabyte's top of the line overclocker-friendly features to make it deserve the UD7 identifier. With its LGA-1156 socket, it supports Intel Core i5 and Core i7 "Lynnfield" processors. It is expected to be out this shopping season.
