OWC DDR3 ECC RDIMM Kit for Supermicro X8 Series

This 16 GB kit contains two 8 GB registered DIMMs built for Supermicro X8DTL, X8DTN+, X8DTT, X8DTU and X8OBN motherboards. It targets administrators who need to extend the service life of existing DDR3 server platforms or populate empty slots in qualified workstations.

Replaces Supermicro MEMDR380L series modules

The modules match the PC3-10600 1333 MHz CL9 1.5 V 2Rx4 specification of the listed Supermicro part numbers, so they serve as direct drop-in replacements. The upgrade is worth it when a system requires registered ECC memory and the current configuration cannot be expanded with unbuffered DIMMs.

Installs in standard 240-pin DDR3 slots

No heat spreader is fitted, so clearance is not an issue in dense server chassis. The main risk is mixing these registered modules with unbuffered memory or installing them in desktop boards that do not support ECC registered operation.

Questions about this item

Does the 240-pin DDR3 RDIMM fit the DIMM slots on a Supermicro X8DTU motherboard?

Yes, the 240-pin DDR3 ECC Registered DIMMs are built for the X8DTU and the other listed X8 series boards.

Which slots should I populate first when installing the two 8 GB modules?

Install the pair in the same channel, typically slots 1 and 3 or 2 and 4, following the board's population guide; the most common error is placing them in adjacent slots of different channels.

Can I later add unbuffered ECC DIMMs alongside this registered kit?

No, registered and unbuffered ECC memory cannot be mixed; any future expansion must use DDR3 1333 ECC Registered RDIMMs.
