64GB DDR4 2933MHz ECC SODIMM kit

This 64GB kit contains four 16GB DDR4 2933MHz CL21 ECC unbuffered SODIMM modules designed for laptops, all-in-one systems and NAS devices. It operates at 1.2V and fits 260-pin slots, providing error-correcting memory for workloads that require data integrity.

Capacity and headroom at 2933MHz

The 64GB total capacity handles large datasets, virtual machines and heavy multitasking in compatible micro servers and NAS units. Systems limited to 2666MHz, 2400MHz or 2133MHz will run the modules at the lower speed, so peak bandwidth is constrained by the platform rather than the memory itself.

JEDEC compliance and lifetime support

Full JEDEC and RoHS compliance ensures a warranty-safe upgrade without violating system warranties. OWC backs the kit with a limited lifetime warranty and a consumer-friendly advanced replacement programme that includes free technical support for installation assistance.

Soalan tentang produk ini

Will the 2933MHz CL21 modules down-clock to 2666MHz or 2400MHz in my older laptop?

The kit is backwards compatible with 2666MHz, 2400MHz and 2133MHz systems, so it will run at the highest speed your platform supports.

How can I confirm the ECC function is active after installing the four 16GB sticks?

Check the BIOS or UEFI memory information screen — it should report ECC enabled and show the full 64GB at the configured speed.

Does the 260-pin SODIMM package include any heat spreaders or installation tools?

The modules ship without heat spreaders and no tools are included; only the four 16GB DDR4 SODIMMs are in the box.
