OWC 128GB (4x32GB) DDR3L 1600 ECC RDIMM Dell PowerEdge M420 M520 M620 M820 M915

128GB DDR3L ECC RDIMM Kit

This kit provides 128GB of DDR3L 1600 memory across four 32GB registered DIMMs. It is built for Dell PowerEdge M420, M520, M620, M820 and M915 servers that require ECC registered modules. The 1.35V DDR3L specification reduces power draw compared to standard DDR3. It suits administrators upgrading blade or rack servers in virtualisation or database roles.

Replaces Unbuffered or Lower-Capacity DIMMs

The upgrade moves a system from unbuffered memory to registered ECC modules, which the target platforms require for stability. It is worth the change when the chassis supports 4Rx4 registered DIMMs and the workload needs error correction at 1600 MT/s. The kit will not work in standard desktop boards that only accept unbuffered memory. It also cannot be mixed with existing unbuffered sticks in the same server.

Four-Module Server Configuration

The 240-pin form factor fits the memory slots of the listed PowerEdge models without adapters. Populating four slots with matched 32GB modules leaves remaining banks free for further expansion if the platform allows. The 1.35V operation helps thermal headroom in dense blade enclosures. JEDEC and RoHS compliance ensures the modules meet the server vendor’s electrical and environmental requirements.
