Server ECC Memory Kit

This OWC kit supplies 64GB of DDR3 1333 registered ECC memory across four 16GB modules. It is built for Supermicro X8DA6 X8DAE X8DAH+ X8DAL and X8DT3 motherboards in workstation or server roles. The 240-pin RDIMM format and 1.5V operation match the platform specifications exactly.

Not for desktop or unbuffered builds

Buyers upgrading a standard desktop PC cannot use these modules because they require registered ECC memory controllers. Systems that only accept unbuffered non-ECC DDR3 will not recognise the kit. Mixing these registered DIMMs with unbuffered memory is also unsupported.

Registered ECC decides compatibility

The single specification that determines fit is the registered ECC RDIMM design combined with DDR3 1333 CL9 timing. Only motherboards that explicitly support registered ECC DDR3 at this speed and voltage will operate correctly with the kit.

Questions about this item

Will the 240-pin DDR3 RDIMMs fit the DIMM slots on a Supermicro X8DAH+ motherboard?

Yes, the kit uses the standard 240-pin DDR3 RDIMM form factor that matches the registered DIMM slots on the listed Supermicro X8 series boards.

What is the correct order to populate the four 16 GB modules on a dual-socket X8DAE board?

Install one module per channel per CPU, starting with the first slot of each channel; the silkscreen labels DIMM A1, B1, C1, D1 for the first processor and E1, F1, G1, H1 for the second.

When should the registered ECC modules be replaced in a server running 24/7?

Replace them if the system logs corrected ECC errors that exceed the platform threshold or if a memory diagnostic reports uncorrectable failures on any of the four sticks.
