Introducing the Motherboard
Introduction
Thank you for choosing the P43T-AD3 motherboard. This motherboard is a high
performance, enhanced function motherboard designed to support the LGA775 socket
Intel
® Yorkfield/Wolfdale processors for high-end business or personal desktop mar-
kets.
There is an advanced full set of I/O ports in the rear panel, including PS/2 mouse and
keyboard connectors, COM, four USB ports, one LAN port and audio jacks for
microphone, line-in and 6-ch line-out.
The ICH10 Southbridge supports two PCI slots which are PCI v2.3 compliant. In
addition, three PCI Express x1 slots are supported, fully compliant to the PCI
Express Base Specification, Revision 1.1. It implements an EHCI compliant inter-
face that provides 480 Mb/s bandwidth for twelve USB 2.0 ports (four USB ports and
four USB 2.0 headers support additional eight USB ports). One onboard IDE connec-
tor supports two IDE devices in Ultra ATA 133/100/66/33 mode. The Southbridge
supports six SATA ports with maximum transfer rate up to 3.0 Gb/s each.
The motherboard incorporates the Intel Eaglelake P43 Northbridge (NB) and Intel
ICH10 Southbridge (SB) chipsets. The Northbridge supports a Front Side Bus (FSB)
frequency of 1333/1066/800 MHz using a scalable FSB Vcc_CPU. The memory
controller supports DDR3 memory
DIMM frequencies of 1600/1333 (OC)/1066/
800. It supports four DDR3 sockets with maximum memory size of 8 GB. DDR3
memory bandwidth of 21.2 GB/s in dual-channel symmetric mode assuming DDR3
1333 (OC) MHz and DDR3 memory bandwidth of 25.6 GB/s in dual-channel sym-
metric mode assuming DDR3 1600 (OC) MHz.
High resolution graphics via one PCI
E xpress x16 slot, intended for Graphics Interface, is fully compliant to the PCI
