OWC 64GB DDR5 4800 ECC RDIMM

This OWC module delivers 64GB of DDR5 4800 memory with CL40 latency and 1.1V operation. It is a 2Rx4 registered DIMM with ECC, built to JEDEC standards for workstation and server platforms. The 288-pin form factor fits compatible DDR5 slots.

For ECC registered server upgrades only

Suits administrators upgrading or repairing systems that require registered ECC DDR5 memory. Not for standard desktop PCs, laptops or consumer motherboards that accept only unbuffered non-ECC modules. Cannot be mixed with load-reduced or unbuffered memory types.

64GB capacity for multi-tasking headroom

Comfortably handles virtualisation workloads, large databases and memory-intensive applications that benefit from error correction. Runs out when a single workload exceeds the module capacity or when the platform limits total installed memory below the required amount.

Questions about this item

Does this 64 GB DDR5 4800 CL40 ECC Registered RDIMM require a motherboard that supports registered ECC DDR5 memory?

Yes. The module is a 288-pin DDR5 ECC Registered DIMM rated at 4800 MT/s with CL40 latency and 1.1 V operation, so the platform must support registered ECC DDR5 memory.

Can I install this 2Rx4 registered ECC module alongside unbuffered or load-reduced ECC DIMMs in the same server?

No. The manufacturer states this registered ECC memory cannot be mixed with unbuffered or ECC load-reduced modules; all DIMMs should be the same registered type.

After installation, how can I confirm the module is running at its rated DDR5 4800 speed and CL40 timings?

Check the system BIOS or a hardware-information utility; it should report the memory operating at 4800 MT/s (PC5-38400) with CAS latency 40 and 1.1 V.
