OWC 64GB DDR4 ECC SODIMM kit

This OWC kit provides 64GB of DDR4 memory in eight 8GB modules that run at 2400MHz with CL17 latency. It is built for laptops, all-in-one PCs and NAS devices that accept 260-pin SODIMMs. The modules are unbuffered and include ECC for data integrity.

ECC unbuffered DDR4 2400MHz CL17

The key specification is ECC combined with unbuffered operation at 2400MHz and CL17 timing. Systems that require error-correcting code memory but do not support registered modules will work with these sticks, while boards without ECC support will ignore the feature. Backward compatibility with 2133MHz platforms is included.

Eight-module kit for multi-slot systems

The package contains eight separate 8GB SODIMMs rather than a single stick or a matched pair. This lets you populate up to eight slots in compatible micro servers or high-capacity NAS units. No heat spreaders are fitted, keeping the modules low-profile for tight chassis. No software or additional accessories are bundled.

Questions about this item

What does 2400MHz mean for actual laptop performance?

The modules run at 2400MHz with CL17 timing, giving standard DDR4 throughput for everyday multitasking and file handling in compatible laptops.

What does PC4-19200 cap in practice?

PC4-19200 is the JEDEC speed grade for DDR4-2400; the memory will operate at 2400MHz or drop to 2133MHz if the system requires it.

Will these 260-pin sticks fit my laptop SODIMM slots?

Yes, each module uses the standard 260-pin DDR4 SO-DIMM form factor used by most modern laptops, all-in-ones and NAS units.
