Server memory kit

This OWC kit delivers 64 GB of DDR3L 1600 ECC registered memory across four 16 GB modules. It is built for Supermicro A+ Server 1012C, 1012G, 1042G, 1122GG and 2022G systems. The modules use 240-pin RDIMM form factor with 2Rx4 organisation and 1.35 V operation. They will not work in standard desktop computers or alongside unbuffered memory.

Capacity and headroom

The 64 GB total provides substantial headroom for virtualisation, database workloads and multi-user file services on supported platforms. Four populated slots leave no room for further expansion on boards limited to four DIMM sockets. Workloads that exceed 64 GB or require higher memory speeds will hit the kit's ceiling.

Build integration

Each module is a registered ECC RDIMM, so the host platform must support registered memory and ECC correction. The 1.35 V DDR3L voltage matches the specified Supermicro servers without additional configuration. Mixing these modules with unbuffered DIMMs is not supported and will prevent boot.

Questions about this item

Will the 1.35V DDR3L 1600 CL11 modules work alongside existing 1.5V DDR3 1600 DIMMs in my Supermicro 1012G?

No, the 1.35V DDR3L RDIMMs cannot be mixed with 1.5V DDR3 or any unbuffered memory; the server requires all slots to use identical registered ECC modules at the same voltage.

How can I confirm the 64GB kit is running at PC3L-12800 CL11 after installation?

Check the BIOS memory information screen or run dmidecode — it should report 1600 MT/s, CL11 timings, 1.35V, registered ECC and 2Rx4 organisation for each of the four 16GB DIMMs.

Does the 4 x 16GB box include heat spreaders or any extra cables?

The kit contains only the four 240-pin DDR3L 1600 CL11 1.35V ECC registered RDIMM modules; no heat spreaders, cables or additional accessories are supplied.
