OWC 32GB DDR3L 1333 PC3L-10600 CL9 4Rx4 240-pin 1.35V ECC Registered RDIMM server RAM

SKU CH-E3XN-WZ78G

A 32 GB DDR3L 1333 ECC registered RDIMM for servers and workstations needing 240-pin 1.35 V memory

  • Total capacity32 GB
  • Rated speedDDR3L 1333 (PC3L 10600)
  • CAS latencyCL9
  • Rated voltage1.35 V
  • Buffer typeRegistered
  • Memory rank4Rx4

Capacity 32GB

Rank 4Rx4

  • 32GB capacity expands server memory headroom
  • DDR3L 1333MHz speed matches PC3L-10600 system requirements
  • ECC registered design protects data integrity in critical workloads
  • 35V low-voltage operation reduces power draw and heat
  • 240-pin RDIMM form factor fits compatible workstation and server slots

Capacity and platform fit

This OWC module provides 32GB of DDR3L ECC registered memory in a single 240-pin RDIMM. It is designed for workstations, servers and NAS systems that require registered error-correcting memory and will not function in standard desktop computers or alongside unbuffered modules.

Sustained-load behaviour

The module runs at 1333MHz with CL9 latency and a low 1.35V supply, matching JEDEC PC3L-10600 specifications. ECC registration adds a clock cycle for address and command buffering, which stabilises data integrity during continuous multi-threaded workloads in server environments.

Installation notes

Insert the 240-pin DIMM into a compatible registered-memory slot; the key notch position prevents misalignment with unbuffered sockets. Because the module is 4Rx4 organisation, the platform must support quad-rank registered DIMMs or the system will not recognise the full capacity.

Questions about this item

How much power does the 1.35V DDR3L module draw when the server runs continuously?

The module operates at 1.35V, which is lower than standard DDR3 voltage, reducing power draw and heat during 24/7 server workloads.

What must the system already have to accept this 240-pin ECC Registered RDIMM?

The motherboard must support DDR3L ECC Registered memory in a 240-pin DIMM slot and cannot mix with unbuffered modules.

Will this 4Rx4 32GB stick work alongside older 2Rx4 DDR3L RDIMMs in the same channel?

Mixing ranks is not recommended; the 4Rx4 organization may prevent dual-channel operation with different rank modules.
