Server ECC RDIMM Upgrade

This 16GB DDR3 registered DIMM targets administrators who maintain Supermicro X9-series motherboards in workstation or server roles. It is not for desktop builders or anyone whose board requires unbuffered memory. The module will not function in consumer platforms that lack ECC registered support.

Registered ECC Specification

The single deciding factor is the registered ECC design with a 2Rx4 organisation running at DDR3 1600 CL11 on 1.5V. Only systems that explicitly accept registered ECC RDIMMs can use this part; unbuffered or non-ECC slots will reject it.

Supermicro Cross-Reference Included

The package provides the OWC part number 1R6D32R416GB as a direct replacement for Supermicro MEMDR316LHL01ER16 MEMDR316LSL01ER16 MEMDR316LSL03ER16 and MEMDR316LSV01ER16. This cross-reference lets procurement match the module to existing spares lists without guesswork.

Questions about this item

What does the 1600MHz rating mean when the module is installed in a Supermicro X9 server?

The module runs at DDR3 1600 speed with CL11 latency, delivering PC3-12800 bandwidth for registered ECC workloads on supported X9DAE, X9DAi, X9DBS, X9SRA and X9SRE boards.

How does the registered ECC interface affect compatibility with standard desktop memory?

Registered ECC modules cannot be mixed with unbuffered desktop DIMMs; they require a workstation or server chipset that supports registered signalling and error correction.

Will the 240-pin 1.5V DIMM fit in the X9DAE memory slots without a heat spreader?

Yes, the bare 240-pin RDIMM at 1.5V matches the X9DAE slot keying and voltage, and the low-profile design clears standard server heatsinks.
