Z8NR-D12 -2 x Socket LGA1366, 12 x DDR3 1333/1066/800 RDIMM/UDIMM max. 192GB RDIMM/max. 48GB UDIMM, 1 x PCI 32bit/33MHz, 3 x PCI-E x8, 1 x PCI-E x16, SATA 2, Aspeed AST2050 8MB VRAM, 2 x Intel 82574L + 1 x Mgmt LAN
<b>Front "Parallel-Balance" CPU and Memory Design</b>
Z8NR-D12 is designed with front “Parallel-Balance” layout, with system fans cool down these two modules directly, the design also facilitates the smooth airflow of the system to get better thermal solution.
<b>ASUS PIKE supported</b>
With the ASUS optional PIKE providing slim-sized and flexible storage options, direct SAS RAID upgrades can be achieved directly via a unique slot—without sacrificing expansion capability. The ASUS PIKE further provides customers with multiple I/O solutions and RAID functions.
<b>ASUS Flex-E Technology</b>
The ASUS Flex-E Technology provides the flexibility to auto-switch between 1 PCI-Ex16 link (Graphic supported) and 2 PCI-E x8 link (for I/O expansion), allowing customers to use PCI-E flexibly.
<b>Optional ASMB4-iKVM Upgrade Kit for Easy Troubleshooting</b>
The optional ASMB4-iKVM upgrade kit provides remote real-time full control access based on BIOS-level to the system by keyboard, video monitor and mouse (KVM over Ethernet) from any local computer anywhere, anytime.
<b>High Quality Components for Greater System Reliability</b>
ASUS is the first company to phase in 6-Phase CPU power, 3-Phase memory power and All Ultra Long Life Solid capacitors on serverboard in the market. These features not only provide the support for high-end 130W CPU, but also delivers highly efficient and reliable operations.
<b>EPU for Extreme Energy Efficiency</b>
With current trends leaning towards energy savings, the Z8NR-D12 is equipped with the ASUS exclusive EPU technology to provide power efficiency by detecting current loadings and intelligently moderating power in real-time to ensure the best power management.
