Server ECC RDIMM kit

This OWC kit provides 64GB of DDR3L 1600 memory in four 16GB registered DIMMs. It runs at 1.35V with CL11 latency and 2Rx4 organisation. The modules carry ECC and are built to JEDEC PC3L-12800 specifications for Dell PowerEdge servers.

For PowerEdge R815, R820, T320, T420, T620

This upgrade suits administrators extending the life of the listed Dell PowerEdge rack and tower servers. It will not work in standard desktop PCs, consumer workstations, or any system that requires unbuffered non-ECC memory.

Registered ECC DDR3L 1600 1.35V

The decisive specification is the registered ECC DDR3L 1600 1.35V 240-pin RDIMM form factor. Only platforms that explicitly support this exact combination can use the kit; all other memory types are physically or electrically incompatible.

Questions about this item

Is the 64 GB kit the only capacity available for these Dell PowerEdge servers?

This listing is the 64 GB kit containing four 16 GB DDR3L 1600 registered ECC modules; other capacities would be separate part numbers.

Will DDR3L 1600 CL11 run at its rated speed in a PowerEdge R820?

Yes — the modules are DDR3L 1600 (PC3L-12800) CL11 and are validated for the R820, so they operate at that speed when the platform supports it.

What does the 240-pin DDR3L registered interface mean for installation?

The kit uses 240-pin DDR3L ECC registered DIMMs at 1.35 V; they fit only DDR3L registered slots and cannot be mixed with unbuffered memory.
