DDR3 memory support
The Z9NH-D12 supports DDR3 memory that features data transfer rates of
1600/1333/1066 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 37.5GB/s. This
voltage reduction limits the power consumption and heat generation of DDR3
which makes it an ideal memory solution. Also, the motherboard can support LR-
DIMM (Load reduced DIMM) which uses a specially designed buffer to reduce the
data load to a single load and can increase overall server system memory capacity.
PCIe 3.0
The motherboard supports the latest PCIe 3.0 device, which doubles the delivered
bandwidth of PCIe 2.0. This enhances system performance while still providing
backward compatibility to PCIe 2.0.
Intel 82574L Gigabit LAN Solution
®
This motherboard features the built-in dual server class Intel ® Gigabit LAN ports,
which helps reduce CPU usage, thus increasing throughput to achieve highly-
reliable network connections, outstanding performance, and better support for
diverse operating systems.
Intel 82574L chipset is VMware-certified to support the virtualization technology.
®
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 C602 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.
Serial ATA III technology
The motherboard supports the Serial ATA III technology through the Serial ATA
interface and Intel ® C602 chipset, delivering up to 6Gb/s data transfer rates.
Additionally, get enhanced scalability, faster data retrieval, double the bandwidth of
current bus systems.
