Server-Specific ECC RDIMM Kit

This OWC kit supplies 32 GB of DDR3L 1600 registered ECC memory in four 8 GB modules. It is built for Dell PowerEdge R815, R820, T320, T420 and T620 servers that require 240-pin DDR3L RDIMMs. Standard desktop systems cannot use registered DIMMs and will not accept this upgrade.

240-Pin Registered DDR3L Fit

Each module runs at 1.35 V with CL11 latency and a 1Rx4 organisation. The registered buffer and ECC function demand a server chipset that supports registered memory; unbuffered consumer boards are incompatible. Installing the matched quad-channel set lets the platform populate four slots in a single operation.

32 GB Registered Capacity

The 32 GB total suits virtualisation hosts, database nodes and memory-hungry legacy applications on the listed PowerEdge models. Workloads that exceed this footprint will require higher-density RDIMMs or additional memory channels not provided by this kit.

Questions about this item

Does the DDR3L 1600 CL11 rating become the bottleneck once the server runs sustained workloads?

The modules operate at DDR3L 1600 with CL11 latency; the memory controller in the Dell PowerEdge R815, R820, T320, T420 or T620 determines the actual sustained throughput.

What is the thermal and power profile of the 1.35 V registered DIMMs during all-day operation?

Each 8 GB module runs at 1.35 V without a heat spreader; registered ECC buffering adds minimal overhead, so power draw and heat stay within standard DDR3L limits for the supported PowerEdge chassis.

Which existing server components are required for this 240-pin RDIMM kit to function?

A compatible Dell PowerEdge R815, R820, T320, T420 or T620 with free 240-pin DDR3L RDIMM slots and a BIOS that supports 1Rx4 registered ECC modules.
