ECC Registered DDR3L Kit

This OWC kit supplies 64 GB of DDR3L memory as two 32 GB registered DIMMs. It is built for Dell PowerEdge R520, R620, R715, R720 and R720xd servers that require ECC registered modules. Standard desktop systems cannot use this memory.

DDR3L 1600 Registered Limits

The modules run at 1600 MHz with CL11 latency at 1.35 V, matching the PC3L-12800 JEDEC standard. Registered buffering and 4Rx4 organisation add electrical load, so the platform chipset and BIOS must explicitly support registered ECC DIMMs. Mixing with unbuffered memory will prevent the system from booting.

64 GB Capacity And Headroom

Two 32 GB DIMMs populate two slots, leaving additional slots free for further expansion if the server supports more than 64 GB. The kit suits virtualization workloads and large database caches that benefit from registered ECC stability. Servers needing more than two DIMMs per channel or higher frequencies will exceed what this DDR3L generation can deliver.

Perguntas sobre este artigo

Should I choose the 64GB kit or buy single 32GB modules instead?

The kit provides two matched 32GB modules for a total of 64GB, ensuring dual-channel operation and balanced ranks across both channels.

What does the 1600MHz rating deliver in a Dell PowerEdge server?

The modules run at DDR3L 1600 with CL11 latency, providing 12800 MB/s peak bandwidth per module when the platform memory controller is set to 1600 MT/s.

Does the 240-pin DDR3L interface limit speed or capacity in these servers?

The 240-pin DDR3L RDIMM form factor is the native slot type for the listed PowerEdge models, so the 1600MHz speed and 32GB per module capacity are fully supported.
