SK hynix HMA82GS6CJR8N 16GB 2Rx8 DDR4 SO-DIMM 2666MHz laptop RAM

SKU CH-5DAK-NX25D MPN HMA82GS6CJR8N

16 GB DDR4 SO-DIMM module rated PC4-21300 at 2666 MHz with CL19 latency and 1.2 V operation

  • 16GB capacity expands multitasking headroom for demanding workloads
  • 2666MHz DDR4 speed delivers responsive data throughput
  • Dual-rank 2Rx8 organisation improves memory bandwidth efficiency
  • CL19 latency at 1.2V balances quick access with low power draw
  • 260-pin SO-DIMM form factor fits standard laptop memory slots

Direct laptop upgrade

This 16 GB DDR4 SO-DIMM is built for notebooks that accept 260-pin PC4-21300 modules. It suits owners who need a single high-density stick rather than a matched pair. Buyers whose systems require ECC registered memory cannot use this non-ECC module.

Simple slot-in install

Align the notch with the socket key, press firmly until the side clips lock, then restart to let the BIOS detect the new capacity. The most common issue is leaving the module partially seated, which causes a blank screen or beep codes. No drivers or configuration utilities are required.

Dual-rank 2Rx8 organisation

The 2Rx8 layout puts two ranks on one module, which some chipsets treat as two logical banks for better bandwidth utilisation. Systems limited to single-rank modules per slot will not recognise the full 16 GB. Verify the motherboard documentation before purchase.

Questions about this item

How can I verify the module is running at 2666 MHz after installation?

Open Task Manager or a tool like CPU-Z and confirm the memory speed shows 2666 MHz with CL19 timings at 1.2 V.

What comes in the box and do I need any extra parts to install it?

The box contains the 16 GB 260-pin SO-DIMM only; no tools or cables are required for a standard laptop memory slot.

Should I choose the 2Rx8 dual-rank version or a single-rank alternative for my laptop?

Select this 2Rx8 dual-rank module if your laptop supports dual-rank 16 GB SO-DIMMs; otherwise a single-rank 16 GB stick may be needed.
