Asus Z8PE-D12X - Motherboard - SSI EEB 3.61 User Manual page 19

DDR3 memory support
The Z8PE-D12X supports UDIMM and RDIMM DDR3 memory that features data transfer
rates of 1333/1066 MHZ to meet the higher bandwidth requirements of server and
workstation applications. The 3-channel DDR3 architecture boosts system performance,
eliminating bottlenecks with peak bandwidth of up to 32GB/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.
82574L LAN Solution
The motherboard comes with dual 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 ICH10R chipset. The Serial ATA II specification 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 flexible
cables with lower pin count and reduced voltage requirements.
USB 2.0 technology
The motherboard implements the Universal Serial Bus (USB) 2.0 specification,
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.
Temperature, fan, and voltage monitoring
The CPU temperature is monitored to prevent overheating and damage. The
system fan rotations per minute (RPM) is monitored for timely failure detection.
The chip monitors the voltage levels to ensure stable supply of current for critical
components.
