Introducing the Motherboard
Introduction
Thank you for choosing the IC41T-A motherboard. This motherboard is a high
performance, enhanced function motherboard designed to support the LGA775 socket
Intel
® Core ™ 2 Extreme/Core ™ 2 Quad/Core ™ 2 Duo/Pentium ® Dual-Core/Celeron ®
Dual-Core/Celeron
®
400 series processors for high-end business or personal desktop
markets.
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 line-out.
*Due to the DRAM maximum size (2 GB per DIMM) at present, the
memory maximum size we have tested is 8 GB.
The ICH7 Southbridge supports three 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 1.0. It implements an EHCI compliant interface
that provides 480 Mb/s bandwidth for eight USB 2.0 ports (four USB ports and two
USB 2.0 headers support additional four USB ports). One onboard IDE connector
supports two IDE devices in Ultra ATA100/66 mode. The Southbridge integrates a
Serial ATA host controller, supporting four SATA ports with maximum transfer rate
up to 3.0 Gb/s each.
The motherboard incorporates the Intel
®
G41 Northbridge (NB) and Intel
®
ICH7
Southbridge (SB) chipsets. The Northbridge supports a Front Side Bus (FSB) fre-
quency of 1333/1066/800 MHz using a scalable FSB Vcc_CPU. The memory con-
troller supports DDR3 memory DIMM frequencies of 1333. It supports two DDR3
sockets with up to maximum memory of 16 GB*. DDR3 Maximum memory band-
width of 12.8 GB/s in dual-channel symmetric mode assuming DDR3 1333 (OC)/
1066/800 MHz. High resolution graphics via one PCI Express slot, intended for
Graphics Interface, is fully compliant to the PCI Express Gen 2.
