256GB DDR4 3200 ECC Kit

This OWC kit provides 256GB of DDR4 3200MHz ECC SODIMM memory across eight 32GB modules. It runs at 1.2V with CL22 latency and uses the 260-pin SO-DIMM form factor. The modules are unbuffered and JEDEC compliant for broad compatibility.

Suits ECC-capable laptops and NAS

This kit suits micro servers, NAS systems, POS terminals and ECC-enabled laptops or all-in-ones that accept 260-pin DDR4 SO-DIMMs. It will not benefit systems that cannot use ECC memory or that are limited to lower maximum capacities per slot. Buyers needing non-ECC modules should consider other options.

256GB total capacity

The single specification that determines fit is the 256GB total capacity delivered as eight 32GB sticks. The platform must support this density per slot and accept an eight-module population. Without that support the kit will not be recognised or will run at reduced capacity.

Questions about this item

Should I pick the 8-module 256GB kit or a smaller capacity for my laptop?

The kit contains eight 32GB modules totalling 256GB; choose it only if your laptop has eight SODIMM slots and supports that density per slot.

What does the 3200MHz rating deliver once the memory is installed?

It runs at DDR4 3200 with CL22 latency at 1.2V, and will down-clock to 2933MHz, 2666MHz, 2400MHz or 2133MHz if the system requires a lower speed.

Does the 260-pin ECC SODIMM interface limit the usable speed or features?

The 260-pin DDR4 SODIMM form factor carries ECC unbuffered operation at the rated 3200MHz; actual throughput is capped by the laptop's memory controller and slot count.
