OWC 8GB DDR3L 1600 ECC RDIMM

This OWC module is an 8GB DDR3L 1600 ECC Registered DIMM designed for compatible workstations, servers and NAS systems. It operates at 1.35V with CL11 latency and a 1Rx4 rank configuration on a 240-pin form factor. The part is not compatible with standard desktop computers and cannot be mixed with unbuffered memory.

Sustained load behaviour

ECC circuitry detects and corrects single-bit errors during continuous operation, helping maintain data integrity in server workloads. Registered signalling reduces electrical load on the memory controller when multiple modules are populated. The DDR3L voltage lowers power draw compared with standard DDR3 at the same 1600 speed.

Pre-order checks

Verify that your system requires DDR3L ECC Registered DIMMs and accepts 240-pin modules at 1.35V. Confirm the platform supports 1Rx4 rank organisation and CL11 timing at 1600 MT/s. Ensure no unbuffered or non-ECC modules are already installed, as mixing is not supported.

  • DDR3L 1600 speed delivers responsive multitasking performance
  • Low 1.35 V voltage reduces power draw and heat
  • 240-pin RDIMM form factor fits compatible workstation slots

Questions about this item

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

The module operates at 1.35V, lower than standard DDR3, reducing power draw and heat output during all-day workloads in compatible workstations or servers.

What must my system already support for this 240-pin ECC Registered DIMM to function?

Your workstation, server, NAS or router must accept DDR3L 1600 PC3L-12800 CL11 1Rx4 240-pin ECC Registered RDIMMs; it will not work with unbuffered memory or standard desktop boards.

Can I add this 8GB DDR3L 1600 registered stick alongside older DDR3L unbuffered modules I already have?

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