SK hynix HMA81GS6CJR8N-VK_UA 8GB DDR4 2666MHz SO-DIMM accessory
8GB DDR4 SO-DIMM laptop memory running at 2666MHz with CL19 latency and 1.2V operation
- 8GB DDR4 capacity expands laptop multitasking headroom
- 2666MHz PC4-21300 speed matches system bus requirements
- 2V DDR4 operation reduces power draw and heat
- 260-pin SO-DIMM form factor fits standard laptop slots
- CL19 non-ECC timing delivers stable everyday performance
Purpose & fit
This SK hynix SO-DIMM module adds 8GB of DDR4 memory to compatible laptops. It suits owners who need a single stick to replace a failed unit or to fill an empty slot. Buyers who want more storage or a matched pair for dual-channel operation should look elsewhere.
Sustained behaviour
The module runs at 2666MHz with a CL19 latency rating and 1.2V voltage. As a 1RX8 non-ECC device it delivers steady throughput for everyday workloads without error-correction overhead. No thermal throttling or speed drop is specified under continuous use.
Thermals noise power
Operating at the standard 1.2V DDR4 level, the stick draws minimal power and produces no audible noise. The low-voltage design keeps heat output modest inside a laptop chassis. No active cooling or additional airflow is required for normal operation.

Questions about this item
Does the 1.2 V DDR4 module run cool enough for all-day use in a thin laptop?
The SO-DIMM operates at the standard 1.2 V DDR4 voltage, so heat output stays within normal laptop memory limits for continuous operation.
My laptop only has a 260-pin SO-DIMM slot — will this 8 GB stick fit and work without extra parts?
Yes, the 260-pin DDR4 SO-DIMM plugs directly into a compatible laptop slot; no cables, adapters or additional hardware are required.
I still have a CL19 2666 MHz stick in the other slot — will this 1Rx8 module run in dual-channel with it?
Both modules share 2666 MHz speed and CL19 latency, so the system can run them in dual-channel mode when capacities and ranks match.
