SK hynix HMA81GS6AFR8N-UH_UA 8GB DDR4 2400MHz CL17 1Rx8 260-pin laptop RAM

SKU CH-Y07M-MBXD7 MPN HMA81GS6AFR8N-UH_UA

8GB DDR4 laptop module running at 2400MHz with CL17 latency and 1.2V operation

  • 8GB capacity for smoother multitasking
  • DDR4 technology at 2400MHz for responsive performance
  • CL17 latency for efficient data access
  • 2V operation reduces power consumption
  • 260-pin SO-DIMM fits standard laptop slots

8GB DDR4 2400MHz SO-DIMM

This is an 8GB DDR4 laptop memory module running at 2400MHz with CL17 latency. It uses a 260-pin SO-DIMM form factor and operates at 1.2V. The non-ECC, 1Rx8 stick is suited for upgrading compatible notebooks.

Who this suits and who should look elsewhere

Buyers needing a single 8GB DDR4 SO-DIMM at 2400MHz for a laptop can use this module. Systems requiring ECC error correction, higher speeds, larger capacities, or desktop DIMM form factors cannot use this part.

Deciding spec: 260-pin SO-DIMM DDR4

The 260-pin SO-DIMM DDR4 interface is the single specification that determines fitment. Only laptops with DDR4 SO-DIMM slots accepting 2400MHz PC4-19200 modules at CL17 can install this memory.

Highlights

  • 8GB capacity for smoother multitasking
  • DDR4 technology at 2400MHz for responsive performance
  • CL17 latency for efficient data access
  • 2V operation reduces power consumption
  • 260-pin SO-DIMM fits standard laptop slots

Questions about this item

My laptop only has one SO-DIMM slot — can I run this 8 GB module as the single stick?

Yes, the module is a single-rank 1Rx8 design, so it works alone in a lone slot without needing a matched pair.

I plan to keep my existing DDR4 SO-DIMM — will this CL17 2400 MHz module run at the same speed and timings as the older stick?

The system will clock both modules to the lowest common speed and latency, so the new stick will match the older one automatically.

After installing the module, how can I confirm the system sees the full 8 GB at 2400 MHz CL17?

Open Task Manager’s Performance tab or run CPU-Z; both will show 8 GB, 2400 MHz and CAS 17 for this module.
