OWC 16GB DDR3L ECC RDIMM kit

This OWC kit supplies 16 GB of DDR3L ECC registered memory in two 8 GB modules. It is built for Dell PowerEdge M420, M520, M620, M820 and M915 servers. The modules run at 1600 MHz with CL11 latency at 1.35 V. They are intended for workstation and server platforms that require registered ECC DIMMs.

240-pin DDR3L 1600 registered ECC

The decisive specification is the 240-pin DDR3L 1600 registered ECC form factor. Only systems that accept DDR3L registered DIMMs at 1.35 V can use this kit. Mixing with unbuffered memory is not supported and will prevent operation.

Suits Dell PowerEdge M-series owners

This upgrade suits administrators extending the life of the listed Dell PowerEdge M-series servers. It is not for desktop PCs, laptops or consumer motherboards that require unbuffered non-ECC memory. Buyers needing higher capacities or different voltages should look elsewhere.

Questions about this item

What does the 1600 MHz speed rating actually deliver inside a Dell PowerEdge server?

The modules run at DDR3L 1600 with CL11 latency, providing the rated PC3L-12800 bandwidth when installed in supported PowerEdge M420, M520, M620, M820 or M915 systems.

How does the DDR3L 1.35 V registered ECC interface affect compatibility?

These are 240-pin DDR3L ECC registered DIMMs at 1.35 V; they only work in servers that accept registered ECC DDR3L and cannot be mixed with unbuffered memory.

Will the 240-pin RDIMMs fit the memory slots in a PowerEdge M620?

Yes, the kit uses standard 240-pin DDR3L RDIMM form factor, which matches the DIMM slots in the PowerEdge M620 and the other listed models.
