System-specific DDR3 kit

This OWC kit provides 32 GB of DDR3 1333 memory across four 8 GB registered DIMMs. It is built for Supermicro X8DA6, X8DAE, X8DAH+, X8DAL and X8DT3 series motherboards. The modules run at 1.5 V with CL9 latency and include ECC error correction. Each stick is a 240-pin 2Rx4 RDIMM without a heat spreader.

Suitable for server upgrades only

This memory fits workstations, servers, NAS units and routers that require DDR3 ECC registered DIMMs. It will not work in standard desktop PCs that use unbuffered non-ECC modules. Mixing these registered sticks with unbuffered memory is not supported. Buyers whose systems need unbuffered DDR3 or a different pin count must choose another product.

Registered ECC DDR3 at 1333 MT/s

The decisive specification is the combination of DDR3 1333 speed, CL9 timing, 1.5 V operation, ECC and registered buffering in a 240-pin 2Rx4 form factor. Only motherboards qualified for this exact registered ECC profile will recognise and use the kit correctly.

Questions about this item

Which motherboards must I already own for this OWC 32GB DDR3 1333 CL9 ECC Registered RDIMM kit to work?

This kit is validated for Supermicro X8DA6, X8DAE, X8DAH+, X8DAL and X8DT3 series motherboards.

Can I keep my existing unbuffered DDR3 modules and add these registered DIMMs alongside them?

No, registered ECC memory cannot be mixed with unbuffered modules; all slots must use registered DIMMs.

How can I confirm the kit is running at the correct 1333 MHz CL9 1.5 V settings after installation?

Check the BIOS memory information or a tool such as CPU-Z to verify DDR3-1333 frequency, CL9 timings and 1.5 V voltage.
