OWC 64GB DDR5 5600 ECC SODIMM Kit

This kit provides 64GB of DDR5 memory across four 16GB modules. It runs at 5600MHz with CL46 latency and operates at 1.1V. The modules use the 262-pin SO-DIMM form factor and include ECC error correction. They are unbuffered and JEDEC compliant for warranty-safe upgrades.

Suited for laptops, all-in-one PCs

Buyers whose systems require registered or buffered memory cannot use this unbuffered kit. Machines limited to lower DDR5 speeds or non-ECC memory will not gain the data-integrity features these modules provide. The four-module layout fills all slots on platforms with four SO-DIMM sockets.

262-pin DDR5 SO-DIMM with ECC unbuffered

The 262-pin DDR5 interface and unbuffered ECC design decide whether this kit fits a specific platform. Only systems that accept 262-pin DDR5 SO-DIMMs and support unbuffered ECC operation can use these modules. Verify the motherboard or system manual for this exact combination before purchase.

Questions about this item

Does this kit use the 262-pin DDR5 SODIMM form factor required by my laptop?

Yes, every module in the kit is a 262-pin DDR5 SODIMM that matches the standard laptop slot.

What is the correct way to seat the four 16 GB modules so the system recognises all 64 GB?

Insert each stick at the same angle until the side clips click, then press down firmly until both latches lock; the common mistake is stopping at the first click.

When should I expect to replace these ECC SODIMMs in a typical workload?

DDR5 ECC modules have no scheduled replacement interval; they are replaced only if a memory test reports correctable errors that exceed the platform threshold.
