16GB DDR3 1333 ECC Registered Kit

This OWC kit provides 16 GB of DDR3 1333 memory in a matched pair of 8 GB modules. Each stick is a 240-pin ECC Registered DIMM rated at PC3-10600 with CL9 latency and 1.5 V operation. It is built for workstations and servers that require registered error-correcting memory.

Supermicro X8 Series Compatibility

The modules are validated for Supermicro X8DA6, X8DAE, X8DAH+, X8DAL and X8DT3 motherboard series. They will not work in standard desktop computers and cannot be mixed with unbuffered memory. Buyers needing non-ECC or unbuffered DDR3 for a consumer platform should look elsewhere.

Registered ECC DDR3 Requirement

This upgrade only fits systems that accept 240-pin DDR3 Registered ECC DIMMs running at 1.5 V. If your motherboard requires unbuffered, non-ECC or a different DDR generation, these modules will not function.

Questions about this item

What is the maximum capacity this 16GB DDR3 1333 ECC RDIMM kit can reach in a Supermicro X8DA6 system?

The kit provides 16GB total across two 8GB modules. Maximum capacity depends on the specific motherboard model and its populated DIMM slots.

How much heat does this 1.5V registered DDR3 memory produce during continuous server workloads?

These modules run at 1.5V without heat spreaders. Registered ECC DDR3 typically operates within standard thermal limits for server environments with adequate chassis airflow.

Which motherboard feature must already be present to use this 240-pin registered ECC memory?

The motherboard must support DDR3 registered ECC RDIMMs. Compatible Supermicro X8DA6, X8DAE, X8DAH+, X8DAL and X8DT3 series boards provide this support.
