16 GB DDR4 SODIMM for laptop upgrades

This 16 GB DDR4 SODIMM module operates at 2666 MHz with a CL19 latency and 1.20 V voltage. It uses a 260-pin SO-DIMM form factor suited to standard laptop memory slots. The unbuffered, non-ECC design matches typical consumer notebook requirements. Buyers needing ECC or registered memory should look elsewhere.

Sustained throughput at PC4-21300 rating

The module is rated for PC4-21300 bandwidth, delivering consistent transfer rates during extended workloads. CL19 timing and 1.20 V operation keep power draw stable across long sessions. Dual-rank 2Rx8 organisation helps maintain throughput when the memory controller accesses multiple banks. Thermal behaviour follows standard JEDEC DDR4 specifications for SO-DIMM modules.

Simple slot installation with key alignment

Align the notch on the 260-pin edge connector with the slot key and press firmly until the side clips engage. No drivers or BIOS configuration are required for basic operation. Common issues include inserting the module at an angle or not seating it fully, which prevents the system from recognising the capacity. Ensure the laptop supports DDR4 SO-DIMM before purchase.

Questions about this item

How much heat and power does the 1.2 V DDR4 module draw when running continuously?

The module operates at 1.2 V, the standard low voltage for DDR4 SO-DIMMs, so power draw and heat stay minimal during all-day use.

What must my laptop already have to accept this 260-pin SO-DIMM?

Your laptop needs a free DDR4 SO-DIMM slot that supports 2666 MHz (PC4-21300) unbuffered non-ECC memory.

Will this CL19 2666 MHz stick work alongside my existing slower DDR4 modules?

Yes, it will run at the speed and latency of the slowest installed module, so mixing with slower DDR4 is trouble-free.
