OWC 1R6D31R408GB 8GB DDR3 1600 ECC RDIMM Supermicro 5037A 7047A memory upgrade

SKU CH-SDTE-15SGB

Adds 8 GB of DDR3 ECC registered memory at 1600 MHz for Supermicro SuperWorkstation 5037A and 7047A systems

  • Total capacity8 GB
  • Rated speedDDR3 1600 (PC3 12800)
  • CAS latencyCL11
  • Rated voltage1.5 V
  • Buffer typeRegistered
  • Memory rank1Rx4

Capacity 8GB

  • ECC registered design protects data integrity in servers
  • 1600 MHz DDR3 speed matches PC3-12800 spec for responsive performance
  • Single 8 GB module simplifies capacity upgrades in Supermicro workstations
  • 5 V operation meets JEDEC standard for reliable compatibility
  • Validated for Supermicro 5037A and 7047A series systems

Targeted server upgrade

This 8GB DDR3 1600 ECC registered DIMM is built for Supermicro SuperWorkstation 5037A and 7047A systems. It delivers 1600MHz speed with CL11 latency at 1.5V for stable server operation.

Single-module simplicity

The upgrade consists of one 1Rx4 240-pin module that installs directly into a compatible slot. No extra cables, brackets or software are included, so deployment stays straightforward for IT staff.

ECC registered requirement

This module uses registered ECC technology and will not work in standard desktop computers or alongside unbuffered memory. Buyers needing non-ECC or consumer-grade RAM must choose a different product.

Questions about this item

Will the 240-pin DDR3 1600 ECC RDIMM need any periodic maintenance or replacement during its service life?

No routine maintenance is required for the module; it is a solid-state component rated for continuous operation and is covered by OWC's limited lifetime warranty with free tech support.

What limit appears first when the 8GB 1Rx4 registered DIMM runs at full DDR3 1600 CL11 speed under sustained load?

The primary limit is the 8GB capacity ceiling; once the working set exceeds that, the system must swap to storage, which is far slower than the 12800 MT/s memory bus.

How much heat and power does the 1.5 V DDR3 ECC RDIMM produce when the workstation runs all day?

At 1.5 V the module draws modest power typical for DDR3 RDIMMs and has no heat spreader, so it relies on chassis airflow; no active cooling is needed on the DIMM itself.
