Server ECC RDIMM kit

This OWC kit supplies 32GB of DDR3 ECC registered memory across four 8GB modules. It is built for Supermicro SuperServer 1026GT, 1026T, 1026TT, 2026TT and 6016GT systems that require registered DIMMs. The modules will not work in standard desktop computers or alongside unbuffered memory.

Registered ECC requirement

The single specification that decides compatibility is the registered ECC design. Only platforms that explicitly support 240-pin DDR3 registered ECC DIMMs can use this kit. Mixing these modules with unbuffered memory or installing them in a non-ECC board will prevent the system from booting.

32GB capacity headroom

The 32GB total capacity handles typical server workloads such as virtualisation, database caching and multi-user file services. It runs out when applications demand more memory than the four installed modules provide or when the platform's maximum supported memory per channel is reached.

Questions about this item

What does the 1333 MHz speed mean once the modules are installed in a Supermicro SuperServer?

The modules run at DDR3 1333 (PC3-10600) with CL9 latency, delivering the rated throughput when the server's memory controller operates at that frequency.

How does the 240-pin registered ECC interface affect what the memory can do in practice?

The 240-pin registered ECC design adds a register between the DRAM and the memory controller, enabling error correction and the 2Rx4 organisation required by the listed Supermicro SuperServer models.

What physical slot and voltage do the 4x8 GB sticks need to fit the compatible Supermicro systems?

Each 8 GB stick uses a standard 240-pin DDR3 DIMM slot and operates at 1.5 V, matching the Supermicro SuperServer 1026, 2026 and 6016 series requirements.
