ASUS Z8NH-D12 Series 1-5
DDR3 memory support
The Z8NH-D12 Series 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 17GB/s.
Furthermore, the supply voltage for the memory is reduced form 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.
