OWC 32GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5V ECC Registered RDIMM 4x8GB memory upgrade

Server-grade ECC RDIMM kit

This OWC kit supplies 32GB of DDR3 ECC registered memory in a matched set of four 8GB modules. It is built for Dell PowerVault NX300 and NX3000 storage servers that require 240-pin RDIMMs. The modules carry the 2Rx4 organisation and CL9 timing specified by those platforms. Desktop or unbuffered systems cannot use this memory.

Steady throughput for storage workloads

At 1333 MT/s and PC3-10600 bandwidth the modules deliver consistent data rates during prolonged file transfers and RAID rebuilds. ECC correction detects and fixes single-bit errors without halting the array, while registered buffering reduces electrical load on the memory controller during sustained multi-threaded I/O. The 1.5V operating voltage keeps power draw predictable under continuous duty.

Validated fit for PowerVault bays

Each stick follows the JEDEC 240-pin RDIMM form factor with no heat spreader, allowing direct installation into the NX300 and NX3000 DIMM slots. The kit replaces the listed Dell part numbers, so firmware recognises the modules without extra configuration. Buyers needing unbuffered ECC or non-ECC UDIMMs for workstations or consumer NAS units should select a different product.
