64 GB DDR4 3200 ECC SODIMM kit

This OWC kit provides 64 GB of DDR4 memory in a four-module set of 16 GB each. It runs at 3200 MHz with CL22 latency and operates at 1.2 V. The modules use the 260-pin SO-DIMM form factor and include ECC error correction for data integrity.

Suited for ECC-capable laptops all-in-ones and NAS

The kit is designed for systems that support unbuffered ECC SO-DIMMs such as compatible laptops all-in-one PCs and NAS devices. It will not function as ECC on platforms that lack ECC support in the chipset and BIOS. Buyers needing non-ECC memory or higher speeds should look at other modules.

260-pin DDR4 3200 ECC SO-DIMM specification

The decisive specification is the 260-pin DDR4 3200 MHz CL22 ECC unbuffered SO-DIMM interface. Only systems with DDR4 SO-DIMM slots that explicitly support unbuffered ECC can use the error-correction feature. Verify your platform documentation before purchase.

Questions about this item

Should I choose the 64 GB kit with four 16 GB modules or a different capacity for my laptop?

This kit provides 64 GB total capacity using four 16 GB SODIMMs. Verify your laptop has four DDR4 SO-DIMM slots and supports 64 GB before purchasing.

What does the 3200 MHz speed mean once the memory is installed in my system?

The modules run at DDR4 3200 (PC4-25600) with CL22 latency. If your platform only supports lower speeds, they will operate at 2933, 2666, 2400 or 2133 MHz instead.

Does the 260-pin DDR4 ECC SO-DIMM interface limit the maximum bandwidth in practice?

The 260-pin DDR4 SO-DIMM form factor carries the PC4-25600 3200 MHz signal. Actual throughput is capped by your laptop's memory controller and the CL22 timing.
