SK hynix HMA82GS6JJR8N-VK_UA 16GB DDR4 SO-DIMM accessory

SKU CH-7JWP-B9HGY MPN HMA82GS6JJR8N-VK_UA

A 16 GB DDR4 SO-DIMM module with dual-rank 2Rx8 organisation, 2666 MHz speed and CL19 latency at 1.2 V

  • 16GB DDR4 capacity expands laptop multitasking headroom
  • 2666MHz PC4-21300 speed keeps data flowing smoothly
  • Dual-rank 2Rx8 organisation boosts memory throughput
  • CL19 CAS latency at 1.2V balances responsiveness and efficiency
  • 260-pin SO-DIMM form factor fits standard laptop slots

Capacity and Compatibility

This is a 16GB DDR4 SO-DIMM module designed for laptop memory upgrades. It suits users who need to increase system memory for multitasking or demanding applications. The dual-rank 2Rx8 organisation and CL19 latency provide standard performance for compatible platforms. Buyers who require ECC error correction or higher-speed modules should verify their requirements before purchase.

Installation Requirements

The module uses a 260-pin SO-DIMM form factor that fits standard laptop memory slots. It operates at 1.2V, matching typical DDR4 laptop power rails, and requires no additional cables or configuration. The PC4-21300 rating indicates a 2666MHz data rate that will down-clock automatically if the system runs at a lower speed. Systems limited to single-rank modules or proprietary memory formats cannot use this part.

Power and Thermals

Operating at 1.2V keeps power draw low during normal workloads. The non-ECC design generates minimal additional heat compared with registered alternatives. No active cooling is required on the module itself; standard laptop airflow is sufficient. The component is rated for typical mobile operating temperatures without throttling.

Questions about this item

Will the 2666 MHz DDR4 module throttle under sustained workloads?

The module runs at standard 1.2 V with CL19 timing and no onboard thermal sensor, so the laptop's memory controller manages any throttling.

How much heat and power does the 16 GB SO-DIMM add during all-day use?

At 1.2 V the dual-rank stick draws only a few watts and produces minimal heat; the laptop's existing cooling handles it without extra noise.

What must my laptop already have for this 260-pin DDR4 stick to work?

A free DDR4 SO-DIMM slot that supports 2666 MHz PC4-21300 non-ECC memory at 1.2 V.
