OWC 4R8D52R464GB 64GB DDR5 4800 CL40 ECC RDIMM memory upgrade

Targeted server upgrade

This OWC module delivers 64GB of DDR5 4800 memory in a single 288-pin ECC Registered RDIMM. It is built for Gigabyte H273-Z82, MZ33-AR0, MZ33-CP0, MZ73-LM0 and MZ73-LM1 workstations and servers. The 2Rx4 organisation and 1.1V operation match the platform requirements exactly. It will not work in standard desktop computers or alongside unbuffered or load-reduced DIMMs.

Sustained workload behaviour

ECC correction and registered signalling keep data integrity intact during continuous operation in servers, NAS systems and network switches. The CL40 latency and PC5-38400 bandwidth provide stable throughput for multi-threaded services and virtualisation hosts. JEDEC and RoHS compliance ensures the module meets industry specifications for long-term deployment without error-rate drift.

Replaces lower-capacity RDIMMs

Installing this 64GB stick upgrades from smaller registered ECC modules to maximise memory density per slot. The jump is worthwhile when current capacity limits container counts, database caching or virtual machine density. It does not add slots, so total capacity still depends on the motherboard's DIMM count and maximum supported memory.
