16 GB DDR4 SO-DIMM for notebooks
This 16 GB DDR4 SO-DIMM uses a 260-pin layout and runs at 2666 MT/s with CL19 latency. It operates at 1.20 V and is unbuffered, making it suitable for standard laptop memory slots. The module is organised as 2Rx8 and carries SK hynix branding.
Dual-rank layout and PC4-21300 rating
The 2Rx8 organisation provides two ranks per module, which can improve memory-controller efficiency on platforms that benefit from rank interleaving. The PC4-21300 designation confirms the 2666 MT/s data rate, so the module delivers that throughput without manual configuration.
16 GB capacity ceiling
A single 16 GB module fills one SO-DIMM slot and suits workloads such as multitasking, virtual machines and large datasets that exceed 8 GB. Systems limited to one slot or a 16 GB maximum cannot expand further, and boards requiring ECC will not use this non-ECC module.

Questions about this item
Will the 2Rx8 rank configuration require any future maintenance or replacement?
The 2Rx8 dual-rank layout is a fixed hardware characteristic; no maintenance or replacement is needed for the rank structure itself.
What limit appears first when the module runs continuously at DDR4 2666 CL19?
Sustained operation stays within the 1.20 V specification, so the first limit encountered is the rated speed and latency envelope of DDR4 2666 CL19.
How much heat and power does the 16 GB stick produce during all-day use?
At 1.20 V the module draws only the power required for DDR4 2666 operation, generating minimal heat that a standard laptop cooling system handles without extra measures.
