64GB DDR4 ECC kit for workstations and NAS

This OWC kit supplies 64GB of DDR4 memory arranged as eight 8GB unbuffered UDIMMs. Each module runs at 2666MHz with a CAS latency of CL19 and operates at 1.2V. The kit is built for desktop PCs, workstations, servers and NAS systems that require error-correcting code memory.

ECC unbuffered UDIMM with JEDEC compliance

The defining specification is the ECC unbuffered 288-pin form factor, which provides single-bit error correction without the latency penalty of registered modules. The memory meets full JEDEC PC4-21300 standards and is backward compatible with 2133MHz and 2400MHz platforms. No heat spreaders are fitted.

Eight modules give headroom for heavy multitasking

With eight populated slots the kit delivers ample capacity for virtualisation, large file handling and concurrent workloads. The 2666MHz speed ceiling and CL19 timing set the performance boundary; systems that demand higher frequencies or lower latencies will need faster-rated modules.

Perguntas sobre este artigo

Will this ECC memory work in a standard desktop motherboard?

The kit is built as unbuffered ECC UDIMM, so it only works in desktop, workstation, server or NAS boards that explicitly support ECC. Standard consumer boards without ECC support will not use the error-correction feature and may not boot.

What speed will the modules run if my system only supports 2400 MHz?

The memory is backward compatible with 2133 MHz and 2400 MHz platforms, so it will automatically down-clock to the highest speed the motherboard allows.

Do I need to populate all eight slots to get the full 64 GB?

Yes, the kit contains eight 8 GB modules; each must be installed to reach the total 64 GB capacity.
