Green extended ATX server motherboard with multiple expansion slots and connectors

Supermicro

Supermicro X6DHE-XB Xeon E7520 DDR SDRAM Extended ATX server motherboard

SKU CH-XGPC-RF15F MPN X6DHE-XB

Supports dual Xeon processors with DDR SDRAM ECC memory and integrated ATA-100 plus Serial ATA-150 RAID storage controllers

  • Dual Xeon E7520 support for parallel workloads
  • Intel E7520 chipset manages multi-processor data flow
  • DDR SDRAM with ECC protects data integrity
  • ATA-100 and Serial ATA-150 RAID controllers secure storage
  • Extended ATX form factor fits high-density server chassis

Server motherboard for dual Xeon systems

The Supermicro X6DHE-XB is an Extended ATX server motherboard built around the Intel E7520 chipset. It targets administrators deploying dual-processor Xeon platforms with DDR SDRAM and ECC memory integrity. The board includes integrated ATA-100 and Serial ATA-150 RAID storage controllers. It is sold without accessories.

Thermals noise and power in normal use

Passive chipset cooling and standard server airflow keep the E7520 within specification during continuous operation. Power draw scales with the installed Xeon processors and populated DIMM slots. Acoustic output depends on the chassis fans required by the Extended ATX form factor. No active cooling components are mounted on the board itself.

Upgrade path from single-socket

This board replaces single-socket server boards when workloads demand a second Xeon processor and ECC memory capacity. The integrated ATA-100 and Serial ATA-150 RAID controllers consolidate storage without a separate HBA. The jump is worth it when your application needs dual-processor throughput and onboard RAID in an Extended ATX footprint.

Questions about this item

How is the Extended ATX board mounted in a chassis and which standoff pattern catches people out?

Mount the board using the Extended ATX standoff layout; the extra row near the rear I/O is often missed, leaving the PCB unsupported at the back edge.

Which components will need replacement after long-term operation?

The DDR SDRAM DIMMs and the onboard CMOS battery are the parts most likely to require replacement over the server's service life.

What throughput ceiling appears first on the storage interfaces during sustained transfers?

The Serial ATA-150 controller tops out at 150 MB/s, so that bus saturates before the parallel ATA-100 channel under heavy sequential I/O.
