  • Low 1.35 V voltage reduces power draw
  • JEDEC and RoHS compliant for warranty-safe upgrades

Server Memory Kit

This OWC kit supplies 64GB of DDR3L ECC Registered memory in a matched pair of 32GB modules. It is built for workstations, servers, NAS systems and routers that require 240-pin DDR3L RDIMMs running at 1600MHz with a CAS latency of 11. The modules operate at the low 1.35V standard and conform to JEDEC PC3L-12800 specifications for warranty-safe upgrades.

Compatibility Constraints

This memory suits administrators upgrading or populating DDR3L registered DIMM slots in qualified server or workstation platforms. It will not function in systems that accept only unbuffered non-ECC DIMMs, nor in platforms that require a different pin count, voltage or DDR generation. Mixing these registered modules with unbuffered memory is not supported.

Decisive Specification

The registered ECC RDIMM design with a 4Rx4 organisation is the single attribute that determines fit. Only motherboards and controllers explicitly qualified for 240-pin DDR3L 1.35V registered ECC DIMMs can use this kit; all other platforms will reject it.

Highlights

  • ECC registered design protects data integrity in servers
  • 64 GB dual-channel kit expands memory capacity
  • DDR3L 1600 speed with CL11 latency
  • Low 1.35 V voltage reduces power draw
  • JEDEC and RoHS compliant for warranty-safe upgrades

Questions about this item

How does the 1600 MHz speed translate once the modules are installed in a server?

The kit runs at DDR3L 1600 (PC3L-12800) with CL11 latency, delivering 12 800 MB/s per module when the platform supports that data rate.

What does the 240-pin DDR3L ECC Registered interface cap in practice?

The 240-pin DDR3L ECC Registered DIMM interface limits operation to 1.35 V and requires a server or workstation chipset that accepts registered ECC modules.

What physical space and slot layout does the 2 x 32 GB kit need to fit?

Each 32 GB module uses a standard 240-pin DIMM form factor without a heat spreader, so two adjacent DDR3L RDIMM slots are required.
