Server ECC RDIMM kit

This OWC kit supplies 64GB of DDR3L ECC registered memory in four 16GB modules. It is built for Dell PowerEdge R520, R620, R715, R720 and R720xd servers that require registered DIMMs with error correction.

240-pin registered design

Each module uses the 240-pin DDR3L form factor and operates at 1.35V with CL11 latency at 1600MHz. The registered buffer reduces electrical load on the memory controller, a requirement for the listed PowerEdge platforms, and the modules cannot be mixed with unbuffered memory.

Verify registered ECC requirement

Confirm your system requires DDR3L registered ECC RDIMMs before ordering; standard desktop boards and unbuffered memory configurations are not compatible. Check that all four DIMM slots can accept 16GB modules and that the server BIOS supports the total 64GB capacity.

Questions about this item

What DDR3L speed and CAS latency does this 1600 kit run at?

Each 16 GB module runs at DDR3L 1600 (PC3L-12800) with CL11 latency and 1.35 V operation.

Will these 240-pin RDIMMs fit a Dell PowerEdge R620?

Yes — the 240-pin registered ECC DIMMs are validated for PowerEdge R520, R620, R715, R720 and R720xd servers.

How do I install the four 2Rx4 modules, and what mistake should I avoid?

Populate identical modules in matched channel pairs per the server manual; do not mix these registered DIMMs with unbuffered memory.
