SK hynix HMA851S6AFR6N 8GB 2x4GB DDR4 2400MHz CL17 laptop RAM

SKU CH-83G5-616HQ MPN HMA851S6AFR6N

An 8 GB DDR4 laptop memory kit with two 4 GB SO-DIMM modules running at 2400 MHz CL17

  • 8 GB total capacity from two 4 GB modules
  • DDR4 2400 MHz speed rated at PC4-19200 bandwidth
  • CL17 latency for responsive system performance
  • 2 V low-voltage operation reduces power draw
  • 260-pin SO-DIMM form factor fits standard laptop slots

Capacity and form factor

This kit delivers eight gigabytes of DDR4 laptop memory in two four-gigabyte SO-DIMM modules. It suits owners of compatible notebooks who need a straightforward capacity increase for everyday multitasking.

Slot count and pin layout

Verify that your laptop has two free 260-pin SO-DIMM slots and accepts non-ECC PC4-19200 modules running at 1.2 volts. Match the part number HMA851S6AFR6N-UH against your service manual because many parts are not interchangeable.

Sustained operation profile

The single-rank 1Rx16 organisation and CL17 latency provide stable throughput during extended workloads at the rated 2400 MHz speed. Standard 1.2 volt operation keeps thermals predictable without requiring extra cooling measures.

Questions about this item

Does the kit contain two 4 GB modules or a single 8 GB stick, and is anything else required for installation?

The kit includes two 4 GB SO-DIMM modules for a total of 8 GB; no extra components are needed beyond a compatible laptop slot.

Should I choose this 2400 MHz CL17 kit or look for a different speed or latency?

This kit runs at 2400 MHz with CL17 timing at 1.2 V; select it when your laptop specifies PC4-19200 DDR4 memory.

What does the 2400 MHz rating mean once the memory is installed in my laptop?

The modules operate at 2400 MHz with CL17 latency, delivering the rated PC4-19200 bandwidth when the system supports that speed.
