1.1 Overview
2807940 uATX Motherboard
Figure 1-1: 2807940 uATX Motherboard
The 2807940 uATX form factor motherboard (Figure 1-1) is
Quad, Intel® Core™2 Duo or Intel® Celeron® CPU processor platform. Both 45nm core
(Wolfdale, Yorkfield) and 65nm core (Conroe) processors are supported. (For a full list of
supported processors please refer to Section 2.3)
Up to four 2.0 GB 667 MHz o
by the Intel® Q35 graphics memory controller hub (GMCH). The Intel® Q35 GMCH also
has a single PCI Express x16 (PCIe x16) expansion lane for a PCIe x16 graphics card.
The integrated Intel® ICH9DO I/O controller hub (ICH) supports six SATA II drives with
data transfer speeds of 3.0 Gbps with SATA RAID configuration support. Twelve USB 2.0
channels, one expansion PCIe x4 channel and two expansion PCI channels provide
flexible expansion options. Support for a (optional) trusted platform module (TPM)
provides additional system security during system boot-up.
r 800 MHz un-buffered DDR2 SDRAM DIMM are supported
an LGA775 Intel® Core™2
