OWC 32GB DDR3L 1600 CL11 4Rx4 240-pin 1.35V ECC Registered RDIMM 1R6T34R432GB

SKU CH-Q3Y7-B61N6

32 GB DDR3L 1600 ECC registered RDIMM for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems

  • Total capacity32 GB
  • Rated speedDDR3L 1600 (PC3L 12800)
  • CAS latencyCL11
  • Rated voltage1.35 V
  • Buffer typeRegistered
  • Memory rank4Rx4

Capacity 32GB

  • ECC Registered design protects data integrity in server workloads
  • 32 GB capacity expands memory headroom for demanding applications
  • DDR3L 1600 speed at 1.35 V lowers power draw versus standard DDR3
  • Single 4Rx4 module simplifies upgrades on Supermicro SuperWorkstation 7037A, 7047AX and 7047GR
  • JEDEC and RoHS compliant for warranty-safe installation

Server-grade ECC RDIMM

This 32 GB DDR3L 1600 CL11 registered module is built for Supermicro SuperWorkstation 7037A, 7047AX and 7047GR systems. It delivers error-correcting, buffered memory required by workstation and server platforms that cannot use standard desktop DIMMs.

JEDEC and RoHS compliant

The module meets JEDEC standards and RoHS requirements, providing a warranty-safe upgrade path for qualified Supermicro workstations. ECC registration and 1.35 V operation match the original OEM specifications for these platforms.

Single-module 240-pin installation

Installation follows standard 240-pin RDIMM procedures for the listed SuperWorkstation models. The module must not be mixed with unbuffered memory, and it will not function in consumer desktop boards that lack registered DIMM support.

Questions about this item

Will the 4Rx4 registered DIMM need any firmware updates or battery-backed maintenance over its service life?

No firmware updates or battery-backed maintenance are required for this DDR3L ECC registered module; it operates as a standard JEDEC-compliant DIMM once installed.

What thermal or power limit appears first when the module runs continuously at 1600 MT/s and 1.35 V?

The 1.35 V DDR3L voltage ceiling is the first sustained-use limit; the module has no heat spreader, so case airflow must keep the DRAM within JEDEC operating temperature.

How much heat and acoustic noise does a single 32 GB 240-pin RDIMM add to a Supermicro SuperWorkstation running 24/7?

The module draws low power at 1.35 V and has no moving parts, so it adds negligible heat and zero acoustic noise; system fans remain the only audible source.
