Server ECC RDIMM Kit

This OWC kit provides 16 GB of DDR3L registered ECC memory in two 8 GB modules. It is built for Supermicro A+ Server series including 1012C, 1012G, 1042G, 1122GG and 2022G systems. The modules run at 1600 MHz with CL11 latency at 1.35 V.

Workstation and server upgrades only

It suits administrators who need to expand capacity in the listed Supermicro platforms with registered ECC DIMMs. It is not for standard desktop computers, laptops or any system that requires unbuffered non-ECC memory or a different DDR generation.

Registered ECC with 1Rx4 organisation

The 240-pin RDIMMs use 1Rx4 registered ECC organisation, which the target Supermicro platforms require for correct operation. Mixing these modules with unbuffered memory will prevent the system from posting.

Questions about this item

Will the 240-pin DDR3L RDIMMs fit the DIMM slots on a Supermicro A+ Server 1012C?

Yes, the 240-pin form factor matches the DDR3L slots on the 1012C, 1012G, 1042G, 1122GG and 2022G series listed for this kit.

What is the correct order for installing the two 8 GB modules in a Supermicro A+ Server?

Populate the lowest-numbered channel slots first — typically CPU1 DIMM slots A1 and B1 — so the registered ECC modules initialise in the sequence the firmware expects.

When should the 1.35 V ECC RDIMMs be replaced in a 24/7 server?

Run a full memory diagnostic at each scheduled maintenance window; replace any module that logs correctable ECC errors or fails the test to avoid uncorrectable failures later.
