32 GB DDR3 ECC RDIMM Kit

This kit provides 32 GB of DDR3 ECC registered memory in two 16 GB modules. It is built for workstations, servers, NAS systems and routers that require registered DIMMs. Standard desktop computers cannot use this memory and it must not be mixed with unbuffered modules.

DDR3 1600 CL11 2Rx4 capacity

The two modules run at 1600 MHz with CAS latency 11 and a 2Rx4 organisation. This configuration handles typical server workloads and multi-tasking scenarios. Systems needing higher frequencies, lower latencies or greater density per slot will exceed what this kit can deliver.

OWC validated upgrade kit

OWC tests every module in its own lab to meet JEDEC and RoHS standards. The kit replaces Supermicro part numbers MEMDR316LHL01ER16 and MEMDR316LSL01ER16 and carries a limited lifetime warranty with free technical support. No additional software or accessories are included.

Questions about this item

Will the 2Rx4 registered DIMMs run alongside my existing unbuffered DDR3 modules?

No, the 2Rx4 registered design cannot be mixed with unbuffered memory; the system requires all slots to use registered ECC modules.

How can I confirm the kit is running at DDR3 1600 CL11 after installation?

Check the BIOS memory information or a tool such as CPU-Z; it should report 1600 MHz, CL11 timings and 1.5 V operation for each 16 GB module.

Does the 32 GB kit include only the two 240-pin RDIMMs or are extra parts supplied?

The box contains the two 16 GB DDR3 1600 CL11 2Rx4 1.5 V ECC registered RDIMMs; no cables, brackets or additional hardware are included.
