Server ECC RDIMM Upgrade

This OWC module delivers 16GB of DDR3 ECC registered memory at 1600MHz with CL11 latency. It uses a 240-pin form factor and operates at 1.5V. The 2Rx4 dual-rank organisation suits compatible workstations, servers, NAS systems and routers.

JEDEC Standard Compliance

The module meets JEDEC and RoHS standards for a warranty-safe upgrade. It is tested to meet or exceed OEM specifications. ECC registered design provides error correction for data integrity in critical workloads. No heat spreader is fitted.

For Registered Memory Slots Only

This memory fits systems requiring DDR3 ECC registered DIMMs. It will not work in standard desktop computers or alongside unbuffered modules. Buyers needing unbuffered ECC or non-ECC DDR3 should look elsewhere.

Questions about this item

Will the 240-pin DDR3 RDIMM need any firmware updates or battery replacements over its service life?

No firmware or battery maintenance is required for this DDR3 RDIMM; it is a passive component rated for continuous operation in qualified workstations and servers.

What thermal limit appears first when the 16GB 1600 CL11 module runs at full load without a heat spreader?

The bare DRAM packages reach their maximum junction temperature before the 1.5 V power envelope becomes a constraint, so case airflow is the primary cooling factor.

How much power does the 1.5 V 2Rx4 registered DIMM draw and how much noise does it add when the server runs 24/7?

The module consumes only the 1.5 V supply current specified by JEDEC for DDR3 1600 and adds no audible noise because it has no moving parts.
