OWC 16GB DDR3 1333 ECC RDIMM

This OWC 16GB DDR3 1333 PC3-10600 CL9 2Rx4 240-pin 1.5V ECC Registered RDIMM is built for Supermicro X8DTL, X8DTN+, X8DTT, X8DTU and X8OBN motherboards. It targets server and workstation administrators who need registered ECC memory to maintain data integrity in multi-socket systems. Standard desktop boards cannot use this module because they require unbuffered non-ECC DIMMs.

Registered ECC with 2Rx4 organisation

The single specification that decides fit is the registered ECC design with 2Rx4 organisation. Only motherboards that explicitly support registered ECC DDR3 at 1333 MHz will accept this module; mixing it with unbuffered memory prevents the system from posting. The 240-pin form factor and 1.5 V operation match the JEDEC DDR3 standard for the listed Supermicro platforms.

Simple DIMM installation with one common pitfall

Installation is a straightforward DIMM insertion into the 240-pin slots, but the most frequent error is populating slots in the wrong order for the specific Supermicro board. Consult the motherboard manual for the correct population sequence and ensure all modules in a channel share identical registered ECC specifications to avoid boot failures.

Questions about this item

How does the 16GB capacity affect a Supermicro X8DTL system?

The single 16GB module adds 16GB of ECC registered memory to a compatible Supermicro X8DTL, X8DTN+, X8DTT, X8DTU or X8OBN motherboard, expanding total system memory for server or workstation workloads.

What does the PC3-10600 1333MHz CL9 rating limit in practice?

The DDR3 1333 PC3-10600 CL9 specification sets the maximum data rate at 1333 MT/s with a CAS latency of 9 cycles; the motherboard chipset and CPU memory controller determine the actual operating speed.

Will the 240-pin 1.5V registered DIMM fit my Supermicro X8DTN+ board?

Yes, the 240-pin DDR3 ECC registered DIMM at 1.5V matches the physical slot and voltage requirements of the listed Supermicro X8DTN+ series motherboards.
