Server Memory Kit

This OWC kit supplies 64 GB of DDR3L ECC Registered memory across four 16 GB modules. It is built for Dell PowerEdge R320, R415, R420, R420XR and R515 servers that require registered DIMMs. The modules will not work in standard desktop computers or in systems that only accept unbuffered memory. Buyers needing consumer DIMMs should look elsewhere.

Registered ECC Operation

Each module implements ECC and register buffering to correct single-bit errors and reduce electrical load on the memory bus. This combination protects data integrity in multi-socket server workloads and allows the platform to populate all slots at the rated speed. The kit cannot be mixed with unbuffered DIMMs, so the full upgrade must use matching registered parts.

1.35 V DDR3L Voltage

The modules run at 1.35 V rather than the standard 1.5 V used by regular DDR3. This lower voltage is required by the supported PowerEdge models and prevents damage or instability if higher-voltage DIMMs are installed. Verify that the target server specifies DDR3L 1600 before ordering.

Perguntas sobre este artigo

Will the 1.35 V DDR3L RDIMMs need any firmware updates or special handling when I swap them into a PowerEdge R420?

No firmware update is required; the 240-pin 1.35 V DDR3L 1600 CL11 2Rx4 registered modules are a direct replacement for Dell part numbers A6761613, A6994465, A7515505, A8255125 and SNP20D6FC/16G.

What is the first limit I will hit when running all 64 GB at full load in a PowerEdge R320?

The memory controller caps DDR3L speed at 1600 MT/s with CL11 latency, so bandwidth tops out at the PC3L-12800 rating rather than any thermal or power ceiling.

How much heat and power do the four 16 GB sticks add when the server runs 24/7?

Each 1.35 V DDR3L RDIMM draws only low-voltage registered power and has no heat spreader, so total added heat stays well within the PowerEdge R415/R515 cooling design.
