64GB DDR3L ECC RDIMM Kit for Supermicro SuperStorage

This kit provides 64GB of DDR3L 1600 registered ECC memory across four 16GB modules. It is designed for Supermicro SuperStorage 2027B, 2027R, 6027R, 6037B and 6037R systems that require 240-pin RDIMMs. It will not work in standard desktop computers or alongside unbuffered memory.

Capacity and headroom for storage workloads

The 64GB total capacity suits virtualisation, ZFS datasets and multi-tenant file services on the listed SuperStorage platforms. Four 16GB 2Rx4 modules fill four DIMM slots, leaving no room for further expansion on a four-slot board. Workloads that exceed 64GB will need a platform with higher density support.

Registered ECC build with 240-pin DDR3L interface

Each module operates at 1.35V with CL11 latency and carries a JEDEC-compliant registered ECC design without heat spreaders. The 240-pin DDR3L form factor fits only compatible Supermicro SuperStorage server and NAS chassis. Mixing with unbuffered DIMMs is not supported.

Questions about this item

Will the 1.35 V DDR3L 1600 ECC RDIMMs work in a Supermicro SuperStorage 6027R that currently runs 1.5 V DDR3 ECC RDIMMs?

The modules run at 1.35 V DDR3L; the 6027R platform supports DDR3L 1600, so they install and operate at the lower voltage without changes.

How can I verify the 64 GB kit is detected at 1600 MHz CL11 after installation?

Check the BIOS memory summary or run dmidecode — each DIMM should show 16 GB, 1600 MT/s, CL11, 2Rx4 registered ECC.

What comes in the box and what must be sourced separately?

The kit contains four 16 GB 240-pin DDR3L 1600 CL11 ECC registered RDIMMs; no cables, brackets or additional memory are included.
