SKU CH-4HJ3-CJSBY MPN SE7520JR2SCSID1

Dual-socket 603/604 server board with six DDR2-400 slots, dual-channel Ultra320 SCSI, two SATA 1.5 Gb/s ports and dual Gigabit LAN

  • Dual-socket Xeon support for scalable server performance
  • 16 GB DDR2-400 capacity with ECC for data integrity
  • Dual Ultra320 SCSI channels for high-throughput storage
  • Dual Gigabit Ethernet ports for redundant networking
  • SSI-TEB form factor fits standard rackmount chassis

Dual-socket Xeon server board

The Intel SE7520JR2SCSID1 is a dual-socket motherboard built around the Intel E7520 chipset for Socket 603 and 604 Xeon processors. It targets system builders assembling rack-mount or pedestal servers that need two CPUs and up to 16 GB of registered DDR2-400 ECC memory across six 240-pin slots.

Installation notes and common issues

The SSI-TEB form factor fits compatible server chassis, but the board requires a 24-pin main power connector plus auxiliary CPU power that some older PSUs lack. Builders often forget the LSI 53C1030 Ultra320 SCSI terminators or leave the onboard ATI RAGE XL video disabled in BIOS, resulting in no post display.

Sustained-load behaviour

Dual Gigabit Ethernet controllers from Intel 82546GB maintain 1000 Mbps throughput under continuous traffic without thermal throttling. The dual-channel DDR2-400 subsystem and Ultra320 SCSI channels deliver steady bandwidth for database or file-serving workloads, while the E7520 chipset handles prolonged 800 MHz system-bus activity within its thermal envelope.

Highlights

  • Dual-socket Xeon support for scalable server performance
  • 16 GB DDR2-400 capacity with ECC for data integrity
  • Dual Ultra320 SCSI channels for high-throughput storage
  • Dual Gigabit Ethernet ports for redundant networking
  • SSI-TEB form factor fits standard rackmount chassis

Questions about this item

How do I confirm the board is running at the correct 800/533 MHz system bus after installing Xeon CPUs?

Enter the BIOS setup during boot and verify the reported front-side bus frequency matches 800 MHz or 533 MHz for the installed processors.

What is included with the SE7520JR2SCSID1 and which parts must be sourced separately?

The motherboard itself is supplied; you must add dual or single Xeon CPUs for socket 603/604, up to 16 GB of DDR2 400 ECC memory in the six 240-pin slots, storage drives for the two SATA 1.5 Gb/s or two ATA 100 ports, and an operating system.

Which memory capacity should I choose for the six DDR2 400 slots to reach the 16 GB maximum?

Populate all six 240-pin slots with 2 GB DDR2 400 ECC modules to achieve the full 16 GB dual-channel limit supported by the E7520 chipset.
