Gigabyte Readies GA-P55A-UD7 to Lead P55A Series
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.

Why is it still there? or w/e thats there.
Only way i can say it, thats AMD. dunno how the absolute newest fare, bad experience on extreme clock, how the hell can they burn up when the cooler is -20 ?
Well basicly it got 32 2.0 lanes but communicates with the old(interconnect), and when all of the guys are at it, they can just buy a I7 and enjoy the trichannel, good chipset, and well, mobo probally will cost the same...
I ve read somewhere that they are actually 12 phases just in half or something that filters better,something like that...:rolleyes:
EVGA did it first:
www.evga.com/products/moreInfo.asp?pn=160-LF-E659-KR
but i still confused how nforce mobo can run ATI crossfire
Even more so than that, any nForce motherboard can run crossfire. If you have multiple PCI-E slots of x4 bandwidth or higher, you can run crossfire. SLIa requires an SLI-certified chipset (which P55 and X58 are, with or without an nForce chip onboard).
Gigabyte announced their reasoning through Raymond Tseng (Associate Vice President, Firmware Division) 27th October in Paris. :pimp:
Anyone check that raid 0 speed will decrease when no CD/DVD ROM connect to the GSATA port (Marvell)?
Lab 1
2 x HD at SATA2_0 / SATA2_1
1 x ROM at SATA2_5 (Intel chipset)
Load default in BIOS
Set raid 0 in BIOS
install windows / driver
download HD tune 4.01 trail version
check raid HD read speed
result
Lab 2
continue above
shutdown
unplug the rom
power on and run HD tune
check raid HD read speed
result
Lab 3
shutdown
connect ROM to GSATA6 or GSATA7 (marvell chipset)
run HD tune
check raid HD read speed
result
Lab 4
continue above
open Intel Matrix storage software
click action / advance
enable write back cache
run HD tune
check raid HD read speed
result
(enable write back cache see follow link)

Lab 1 and 2 result is very slow
Lab 3 result is faster
Lab 4 result is the most faster
But the problem is - IF connect the rom to GSATA port(Marvell) the raid HD speed will increase.
