Asus P8B-E/4L User Manual

ASUS P8B-E/4L 1-5
DDR3 memory support
The P8B-E/4L supports UDIMM DDR3 memory that features data transfer
rates of 1333/1066 MHZ to meet the higher bandwidth requirements of server
and workstation applications. The 2-channel DDR3 architecture boosts system
performance, eliminating bottlenecks with peak bandwidth of up to 21GB/s.
Furthermore, the supply voltage for the memory is reduced from 1.8 V for DDR2 to
just 1.5V for DDR3. This voltage reduction limits the power consumption and heat
generation of DDR3 which makes it an ideal memory solution.
PCIe 2.0
This motherboard supports the latest PCIe 2.0 device for twice the current speed
and bandwidth. This enhances system performance while still providing backward
compatibility to PCIe 1.0 devices.
Intel
®
82574L LAN Solution
The motherboard comes with quad Gigabit LAN controllers and ports which provide
a total solution for your networking needs. The onboard Intel
®
82574L Gigabit LAN
controllers use the PCI Express interface and could achieve network throughput
close to Gigabit bandwidth.
Enhanced Intel SpeedStep Technology (EIST)
The Enhanced Intel SpeedStep Technology (EIST) intelligently manages the
CPU resources by automatically adjusting the CPU voltage and core frequency
depending on the CPU loading and system speed or power requirement.
Serial ATA II technology
The motherboard supports the Serial ATA II 3 Gb/s technology through the Serial
ATA interface and Intel
®
C204 chipset. The Serial ATA II specication provides
twice the bandwidth of the current Serial ATA products with a host of new
features, including Native Command Queuing (NCQ), Power Management (PM)
Implementation Algorithm, and Hot Swap. Serial ATA allows thinner, more exible
cables with lower pin count and reduced voltage requirements.
Serial ATA III technology
The motherboard supports the Serial ATA III technology through the Serial ATA
interface and Intel
®
C204 chipset, delivering up to 6Gb/s data transfer rates.
Additionally, get enhanced scalability, faster data retrieval, double the bandwidth of
current bus systems.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0 specication,
dramatically increasing the connection speed from the 12 Mbps bandwidth on USB
1.1 to a fast 480 Mbps on USB 2.0. USB 2.0 is backward compatible with USB 1.1.
