Asus P5M2, User Manual, Page: 19 / 189

ASUS P5M2 Series 1-
DDR2-533/667 memory support
The motherboard supports DDR2 memory which features data transfer rates of
up to 667 MHz to meet the higher bandwidth requirements of the latest server
applications. The dual-channel memory architecture doubles the bandwidth of your
system memory to boost system performance, eliminating bottlenecks with peak
bandwidths of up to 10.7 GB/s.
PCI Express™ interface
The motherboard fully supports PCI Express, the latest I/O interconnect technology
that speeds up the PCI bus. PCI Express features point-to-point serial
interconnections between devices and allows higher clockspeeds by carrying data
in packets. This high speed interface is software compatible with existing PCI or
PCI-X specifications.
Zero-Channel RAID (ZCR) card solution (P5M2/SAS only)
The motherboard comes with a PCI-X slot (the green slot on the P5M2/SAS
model) that supports an optional Zero-Channel RAID card. The Zero-Channel
RAID card allows you to create all types of RAID configurations for your storage
devices. The ZCR capability provides a cost-effective, high-performance, and
added reliability for your server system.
Gigabit LAN solution
The motherboard comes with dual Gigabit LAN controllers and ports to provide
a total solution for your networking needs. The onboard Broadcom
®
BCM5721
Gigabit LAN controllers use the PCI Express interface and could achieve network
throughput close to Gigabit bandwidth.
Serial ATA II technology
The motherboard supports the Serial ATA II technology through the Serial ATA
interfaces controlled by the Intel
®
ICH7R. The SATA specification allows for thinner,
more flexible cables with lower pin count, reduced voltage requirement, and up to
300 MB/s data transfer rate.
Built-in SATA RAID solution
The Intel
®
ICH7R allows RAID 0, RAID 1, RAID 0+1, and RAID 5 configuration
for SATA hard disk drives via the Intel
®
Matrix Storage Manager (under Windows
Operating System) or the LSI Logic Embedded SATA RAID Setup Utility (no RAID
5).
