1.1 Overview
Figure 1-1: 3307840 PICMG 1.3 CPU Card
The 3307840 PICMG 1.3 form factor CPU card (Figure 1-1) is an LGA775 Intel® Core™2
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 or 800 MHz un-buffered DDR2 SDRAM DIMM are supported by
the Mobile 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
on the backplane.
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, four expansion PCIe x1 channels and four expansion PCI channels provide
flexible expansion options. Support for a(optional) trusted platform module (TPM) provides
additional system security during system boot-up. High Definition Audio (HDA) support
ensures an HDA audio kit can be easily implemented on the 3307840.
