What this module is
This is an 8GB DDR4 SO-DIMM laptop memory module rated at 2666MHz with CL19 latency. It runs at 1.2V and uses a 260-pin non-ECC design. The single-rank 1Rx8 layout suits mainstream notebook upgrades.
Practical limits of DDR4 SO-DIMM
The 2666MHz speed and CL19 timing define the data rate your system can sustain. Non-ECC operation means no error correction for critical workloads. The 1.2V standard voltage matches typical laptop power envelopes.
Check your laptop before ordering
Verify the original part number matches HMA81GS6DJR8N-VK_UA or PC4-2666V-SA2-11 exactly. Confirm your notebook accepts 260-pin DDR4 SO-DIMM modules. Ensure the memory slot supports 1Rx8 rank configuration.

Questions about this item
Should I choose the 8GB 1Rx8 DDR4 SO-DIMM or a different capacity?
This module provides 8GB in a single 1Rx8 rank at 2666MHz CL19. It suits laptops with one free SO-DIMM slot; add a second identical stick for dual-channel bandwidth.
What does the 2666MHz speed deliver in my laptop?
The 2666MHz clock yields PC4-21300 bandwidth. Actual throughput depends on the CPU memory controller and whether the system runs single- or dual-channel.
Does the 260-pin SO-DIMM interface limit performance?
The 260-pin DDR4 SO-DIMM form factor caps the module at the JEDEC 2666MHz standard; faster DDR4 speeds require a different platform.
