4 GB DDR4 laptop module
This SK hynix SO-DIMM delivers 4 GB of DDR4 memory at 3200 MHz for laptops, notebooks and all-in-one PCs. The 260-pin unbuffered module runs at 1.20 V with a CAS latency of 22. It suits users upgrading a single slot or adding capacity to a compatible system.
Sustained operation at 3200 MHz
The module maintains its rated 3200 MHz speed under continuous workloads thanks to standard DDR4 signalling and 1.20 V operation. Single-rank 1Rx16 organisation keeps electrical loading low, helping stability during extended sessions. No ECC circuitry means all bandwidth serves application data.
CL22 latency at 1.20 V
The decisive specification is CAS latency 22 at the standard 1.20 V DDR4 voltage. Systems requiring lower latency or higher voltage modules will not match this timing profile. Buyers needing ECC error correction or registered buffering must choose a different part.

Questions about this item
How much heat and power will this 1.20 V DDR4 3200 MHz module draw during continuous all-day use?
The module runs at the standard DDR4 voltage of 1.20 V, keeping power draw and heat output low for typical laptop workloads.
What slot type and form factor must my laptop already have for this 260-pin SO-DIMM to fit?
Your laptop needs a 260-pin DDR4 SO-DIMM slot; the stick measures 133 mm long, 30 mm high and 3 mm wide.
Will this CL22 single-rank stick run at its rated speed when paired with slower DDR4 modules already in the system?
The memory controller will down-clock all modules to the speed of the slowest stick, so this 3200 MHz module will run at the lower frequency.
