OWC 1R3D32R408GB 8GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5V ECC Registered RDIMM Server Memory

8 GB DDR3 ECC Registered RDIMM

This 8 GB DDR3 module runs at 1333 MT/s with CL9 latency and 1.5 V operation. It uses a 240-pin registered DIMM form factor with 2Rx4 organisation and ECC error correction. The part is designed for workstation and server platforms that require registered memory. It replaces Dell part numbers A4188276, A6199968 and A6996808.

Registered DDR3 interface limits

Registered DDR3 memory cannot be mixed with unbuffered modules in the same system. The 1333 MT/s JEDEC standard defines the maximum data rate for this module. Capacity scales with the number of slots and the memory controller's rank limit. Exceeding the controller's supported rank count per channel will prevent the system from posting.

Check your platform before ordering

Verify that your motherboard or server explicitly supports DDR3 ECC registered RDIMMs. Confirm the maximum memory capacity per slot and the total rank limit per channel. Ensure all installed modules share the same capacity, speed and rank configuration for stability. This module will not work in standard desktop computers that require unbuffered memory.
