16 GB DDR4-3200 SO-DIMM kit

This kit provides 16 GB of DDR4 laptop memory as two 8 GB modules rated at 3200 MT/s with CL22 latency. It suits owners of compatible notebooks who need to reach 16 GB total capacity for everyday multitasking and office workloads.

Straightforward 260-pin installation

The modules use the standard 260-pin SO-DIMM form factor and operate at 1.20 V, so they fit the usual DDR4 laptop slots without extra configuration. Problems occur when a system only supports lower speeds or requires 1Rx8 organisation, which these unbuffered non-ECC sticks may not satisfy.

Verify DDR4 SO-DIMM support first

Before ordering, confirm the laptop accepts DDR4 SO-DIMM memory and can run at 3200 MT/s or will down-clock automatically. Check the maximum capacity per slot and the total limit in the manual, and ensure the board does not require registered or ECC modules.
