Green extended ATX motherboard with dual LGA771 sockets and eight FB-DIMM slots

Supermicro

Supermicro X7DAE Intel 5000X LGA771 DDR2 E-ATX motherboard

SKU CH-9AN3-YZTJS

Dual-socket LGA771 board with Intel 5000X chipset, eight FB-DIMM slots for DDR2 at 533 or 667 MHz, two PCIe x16 and two PCI-X expansion slots, six Serial ATA-300 ports with RAID.

  • Dual Xeon 5000-series CPUs boost multi-thread throughput with two LGA771 sockets
  • Eight FB-DIMM slots support 533 or 667 MHz DDR2 for high memory bandwidth
  • Dual PCIe x16 plus two 133 MHz PCI-X slots give flexible expansion
  • Intel 82563EB controller delivers Gigabit Ethernet connectivity
  • E-ATX board measures 12 by 13.1 inches for full-size chassis fit

Dual-socket Xeon workstation board

The Supermicro X7DAE is an extended ATX motherboard built around the Intel 5000X chipset for dual LGA771 Xeon processors. It targets professionals maintaining legacy compute clusters or specialised server workloads that still rely on DDR2 FB-DIMM memory. Eight 240-pin slots accept 533 MHz or 667 MHz modules at 1.8 V. The board measures 12 in by 13.1 in and includes dual Gigabit Ethernet via the Intel 82563EB controller.

Thermals noise and power

The board operates from 208 V to 230 V AC input and provides two CPU sockets with independent cooling zones. Two PCIe x16 slots and two 133 MHz PCI-X slots share airflow paths with the memory banks, so case ventilation must handle sustained multi-socket loads. Six Serial ATA-300 ports and one ATA-100 connector draw minimal extra power, while the onboard IPMI subsystem uses Web, SNMP and Telnet for remote sensor monitoring without adding acoustic load.

Replaces older dual-socket platforms

This motherboard upgrades systems that previously used single-socket or lower-bandwidth chipsets and now need 1333 MHz front-side bus throughput. The jump is worth it when workloads scale across two Xeon 5000 series processors and require the combined memory bandwidth of eight FB-DIMM channels. Buyers who need newer memory standards, single-thread optimisation or integrated modern storage interfaces will not be served by this platform.

Questions about this item

How do I install the board in a chassis and which standoff pattern must I use?

Mount the 12 by 13.1 inch E-ATX board using the extended ATX standoff holes; the step often missed is fitting all nine standoffs before tightening any screw to prevent flex.

What maintenance or replacement will the FB-DIMM memory need later?

The eight 240-pin FB-DIMM slots run at 1.8 V with 533 or 667 MHz DDR2; plan to replace any module that shows correctable ECC errors during POST.

What limit appears first when the dual Xeon 5000 series CPUs run at full load continuously?

The 1333 MHz front-side bus and FB-DIMM bandwidth saturate before the PCI-X 133 MHz or Serial ATA-300 interfaces become bottlenecks.
