64 GB DDR5 5200 ECC SODIMM kit

This OWC kit delivers 64 GB of DDR5 memory across four 16 GB modules. It is built for laptops, all-in-one PCs and NAS appliances that accept 262-pin SO-DIMMs and can use ECC unbuffered memory. The package targets professionals who need data-integrity protection in compact systems.

DDR5 5200 CL42 at 1.1 V

The decisive specification is the JEDEC-standard DDR5 5200 speed with CL42 latency at 1.1 V. Systems that require this exact speed grade and voltage will recognise the modules automatically; platforms limited to lower DDR5 speeds or non-ECC memory will not be compatible.

Steady throughput with ECC overhead

Under sustained workloads the ECC circuitry continuously corrects single-bit errors without halting the controller. The unbuffered design keeps latency low while the 1.1 V operation limits thermal output during long compile, virtualization or file-serving sessions.

Questions about this item

What does the 5200 MHz rating mean once the kit is installed in a laptop?

The 5200 MHz rating is the JEDEC-standard data rate the modules run at by default, delivering PC5-41600 bandwidth without manual overclocking.

How does the DDR5 interface and CL42 latency affect real-world throughput?

DDR5 at CL42 provides the standard 5200 MT/s transfer rate; the CAS latency of 42 cycles is the JEDEC baseline for this speed grade.

Will the 262-pin SODIMM modules fit my laptop's memory slots?

Yes — each 16 GB module uses the standard 262-pin DDR5 SODIMM form factor and 1.1 V operation required by compatible laptops and all-in-one systems.
