Server ECC RDIMM upgrade

This 8 GB DDR3 1600 module is built for Supermicro X9DAE, X9DAi, X9DBS, X9SRA and X9SRE motherboards. It targets administrators who need registered ECC memory for workstation, server, NAS or router platforms.

Capacity and headroom

A single 8 GB rank adds meaningful capacity to multi-slot server boards running memory-intensive workloads. The registered buffer and ECC protect data integrity, but the DDR3 1600 interface limits throughput on modern compute tasks.

Registered ECC constraint

This module uses 1.5 V registered ECC DDR3 technology and will not work in standard desktop systems or alongside unbuffered DIMMs. Buyers must verify their platform requires registered ECC memory before ordering.

Highlights

  • ECC registered design prevents data corruption in servers
  • 1600 MHz DDR3 speed matches PC3-12800 spec for responsive workloads
  • CL11 latency at 1.5 V keeps power draw low
  • Single 8 GB 1Rx4 module simplifies capacity expansion
  • Validated for Supermicro X9DAE, X9DAi, X9DBS, X9SRA, X9SRE motherboards

Questions about this item

Will this 240-pin DDR3 1600 ECC Registered RDIMM work alongside the existing unbuffered modules in my Supermicro X9DAE server?

No, the registered design cannot be mixed with unbuffered memory; all slots must use registered ECC modules for the system to operate correctly.

How can I verify the 8GB CL11 module is running at the correct 1600 MHz speed after installation?

Check the BIOS memory information or use a tool such as CPU-Z to confirm the module reports DDR3-1600 (PC3-12800) at CL11 latency.

Does the single 1Rx4 1.5 V stick ship with any additional parts or do I need to buy a heatsink separately?

The box contains only the bare 240-pin RDIMM; no heatspreader, cables or extra hardware are included or required for standard server use.
