Dell PowerEdge server memory kit

This 64GB kit contains four 16GB DDR3L 1600 ECC registered RDIMMs built for Dell PowerEdge M420 M520 M620 M820 and M915 blade servers. It targets administrators who need to expand capacity in those specific platforms without mixing registered and unbuffered modules.

Capacity and headroom

The 64GB total provides ample headroom for virtualisation workloads and database caches typical of the supported blades. Systems requiring more than 64GB or configurations that demand unbuffered DIMMs will not be served by this kit.

Registered ECC DDR3L 1600 CL11

Registered ECC operation at 1.35V and CL11 latency is the decisive specification; the modules will not function in desktop boards or in servers that require unbuffered memory.

Questions about this item

Will these 240-pin DDR3L 1600 RDIMMs work alongside existing 2Rx4 modules in my M620?

Yes. The kit uses the same 240-pin DDR3L 1600 PC3L-12800 CL11 2Rx4 registered ECC specification, so it matches the electrical and timing parameters of identical modules already installed in the M620.

How can I confirm the 64 GB kit is running at 1600 MT/s with ECC active after installation?

Enter the system BIOS or iDRAC interface; both will report each DIMM as 16 GB DDR3L 1600 registered ECC and show the total 64 GB operating at the rated speed with error correction enabled.

Does the box contain only the four 16 GB RDIMMs or are any tools or cables included?

The package contains the four 16 GB DDR3L 1600 CL11 2Rx4 240-pin 1.35 V ECC registered RDIMMs and nothing else; no tools, cables or additional hardware are supplied.
