64GB DDR4 ECC SODIMM Kit

This OWC kit provides 64GB of DDR4 ECC memory in a matched pair of 32GB modules. Each stick runs at 3200MHz with CL22 latency at 1.2V. The 260-pin SO-DIMM form factor fits laptops, all-in-one PCs and compatible NAS units that accept unbuffered ECC memory.

Suited for ECC-capable mobile systems

The modules are designed for laptops, all-in-one desktops and NAS devices that specifically support unbuffered ECC SO-DIMMs. Builders whose systems require registered or load-reduced memory, or platforms that only accept non-ECC modules, should look at a different specification.

Unbuffered ECC with 3200MHz JEDEC rating

The decisive specification is the combination of unbuffered ECC operation at a standard 3200MHz JEDEC speed. Systems that need registered ECC or cannot enable ECC in the BIOS will not benefit from this kit.

Questions about this item

Does the 1.2 V DDR4 3200 MHz ECC SODIMM run hot or draw extra power during all-day use in a laptop?

The modules operate at the standard 1.2 V DDR4 voltage with no heat spreader, so thermal output and power draw stay within normal JEDEC limits for continuous laptop or NAS workloads.

What must my laptop or NAS already have to accept this 260-pin 64 GB dual-channel ECC kit?

The system needs two free DDR4 SO-DIMM slots, a memory controller that supports ECC unbuffered modules, and BIOS or firmware that can initialise 32 GB per rank at 3200 MHz.

Will these CL22 3200 MHz sticks down-clock reliably if I keep my older 2666 MHz or 2400 MHz DDR4 modules installed?

Yes, the kit is backward compatible with 2933, 2666, 2400 and 2133 MHz speeds, so mixed populations will run at the highest common frequency supported by the platform.
