Server ECC Registered Memory

This OWC kit provides 64GB of DDR4 3200MHz ECC Registered RDIMM memory across four 16GB modules. It is built for workstations and servers that require registered, error-correcting memory. Standard desktop computers cannot use these modules. Mixing them with unbuffered memory is not supported.

288-Pin RDIMM Upgrade

Each module fits a 288-pin DDR4 slot and operates at 1.2V with CL22 latency. The registered design places a buffer between the memory controller and the DRAM chips, reducing electrical load on the server platform. A motherboard with registered DIMM support and ECC capability is required for operation.

64GB Quad-Channel Capacity

The four-module kit delivers 64GB total capacity for multi-threaded workloads and virtualisation. JEDEC compliance ensures stable operation at the rated 3200MHz speed. Systems needing more than 64GB or unbuffered memory will require a different memory type.

Questions sur cet article

Will the CL22 latency become the bottleneck when the server runs at DDR4 3200 continuously?

CL22 is the rated timing for DDR4 3200; the controller operates at this latency under sustained load.

How much heat does a 4 x 16 GB registered kit produce when fully populated all day?

Each 1.2 V module runs without a heat spreader; registered DIMMs typically stay within JEDEC thermal limits in normal server airflow.

Must the motherboard already support 2Rx4 registered ECC RDIMMs for this kit to work?

Yes, the platform must accept 288-pin DDR4 registered ECC memory with 2Rx4 organisation.
