Capacity and form factor

This is a single 16 GB DDR5 module built to the 262-pin SO-DIMM standard. It runs at 5600 MT/s with a CAS latency of CL46 and operates at 1.1 V, making it a direct drop-in upgrade for compatible laptops, all-in-one PCs and NAS devices.

Suitable systems and limits

The module includes on-die ECC and is unbuffered, so it serves users who need error correction without registered memory. It will not work in systems that require registered DIMMs, desktop UDIMMs, or any platform limited to a lower DDR generation or a different pin count.

Deciding specification

The 262-pin DDR5 SO-DIMM form factor combined with on-die ECC at 5600 MT/s is the single attribute that determines whether this module fits and functions in a given machine.

Questions about this item

How can I confirm the 16 GB DDR5 5600 module is running at CL46 after installation?

Open Task Manager or your BIOS and check that the installed memory shows 16 GB at 5600 MT/s with a CAS latency of 46; the ECC unbuffered design will also be reported by most system utilities.

What comes in the box and do I need any extra parts to install this 262-pin SODIMM?

The package contains one 16 GB DDR5 5600 CL46 1.1 V ECC unbuffered SODIMM; no cables, brackets or tools are included, and none are required for a standard laptop or all-in-one slot.

Should I choose the single 16 GB stick or add a second one for my laptop?

This listing is a single 16 GB module (part number 5C6D51R816GB); if your system has two slots and supports dual-channel operation, buying two identical modules will enable that mode.
