Capacity 64GB (4 x 16GB)

  • 64GB total capacity across four 16GB modules for heavy multitasking
  • ECC support detects and corrects memory errors in critical workloads
  • DDR4 2400 CL17 at 1.2V balances speed with low power draw
  • 260-pin SO-DIMM form factor fits laptops, all-in-ones and NAS units
  • Backward compatible with 2133MHz systems for flexible upgrades

Capacity and kit layout

This kit provides 64GB of DDR4 memory in four 16GB SO-DIMM modules. Each stick runs at 2400MHz with a CL17 latency and operates at 1.2V. The unbuffered ECC design adds error correction for data integrity in supported systems.

Suitable systems and limits

It fits laptops, all-in-one PCs, micro servers and NAS units that accept 260-pin DDR4 SO-DIMMs and can use ECC memory. Systems that lack ECC support in the BIOS, desktop boards requiring full-size DIMMs, or platforms restricted to a different DDR generation will not work with these modules.

Deciding specification

The modules are ECC unbuffered DDR4 SO-DIMMs running at 2400MHz CL17. If your hardware requires non-ECC memory, registered DIMMs, a different form factor or another DDR generation, this kit is incompatible.

Questions about this item

Does my laptop need a 260-pin DDR4 SO-DIMM slot to use this kit?

Yes, the modules are 260-pin DDR4 SO-DIMMs, so the system must provide a matching DDR4 SO-DIMM socket.

Will these 2400MHz ECC modules run in a system that only supports 2133MHz?

The kit is backwards compatible with 2133MHz and will operate at the lower speed if the platform requires it.

How can I confirm the full 64GB is recognised and ECC is active after installation?

Check the BIOS or OS memory report for 64GB total and verify ECC status shows enabled or corrected errors are logged.
