OWC 64GB (2x32GB) DDR5 5200 PC5-41600 CL42 2Rx4 ECC Registered RDIMM server RAM

ECC Registered DDR5 for servers

This 64 GB kit delivers two 32 GB DDR5 5200 modules built to the PC5-41600 standard with CL42 latency. Each stick is a 288-pin registered DIMM operating at 1.1 V and organised as 2Rx4 with on-die ECC. The memory is designed for workstations, NAS appliances, servers and network switches that require registered ECC modules.

Replacing unbuffered or lower-capacity DDR5

The jump is worth it when a platform demands registered ECC and cannot accept unbuffered or load-reduced DIMMs. Moving from single-rank or non-ECC memory adds the error correction and signal buffering that multi-socket boards and mission-critical workloads expect. The dual-channel kit also doubles density per slot compared with 16 GB or 8 GB alternatives.

Fits registered-DIMM slots in qualified systems

Installation requires a motherboard or riser wired for 288-pin DDR5 RDIMMs and a BIOS that supports the JEDEC PC5-41600 speed grade. No heat spreader is fitted, so airflow across the modules must be provided by the chassis. The kit frees the remaining DIMM slots for further registered ECC expansion up to the platform limit.
