16 GB DDR4 3200 SODIMM kit

This SK hynix kit delivers 16 GB of DDR4 memory in two 8 GB SO-DIMM modules rated at 3200 MT/s with CL22 latency. The 260-pin unbuffered sticks operate at the standard 1.2 V and carry no ECC functionality. It is built for notebooks and small-form-factor systems that accept DDR4 SO-DIMM memory.

Suits mainstream laptop upgrades.

The modules fit typical consumer laptops and mini PCs that use unbuffered non-ECC DDR4 SO-DIMM slots. Buyers whose platforms require ECC protection, registered DIMMs, or a different DDR generation should look elsewhere. The kit also does not serve desktop DIMM sockets or systems limited to lower DDR4 speeds.

The deciding spec is DDR4 3200 SO-DIMM 260-pin

Compatibility hinges on the DDR4 SO-DIMM 260-pin form factor running at 3200 MT/s. If the target machine calls for this exact memory type and pin count, the kit will install and operate at its rated speed. Any other memory standard or pin layout means the modules will not fit or function.

Questions about this item

How can I confirm the 3200 MT/s speed and CL22 latency are active after installing the HMA81GS6CJR8N-XN modules?

Open Task Manager or CPU-Z and verify the memory tab shows 3200 MT/s and CAS latency 22; if the BIOS defaults to a lower JEDEC profile, enable the XMP or DOCP profile that matches the rated PC4-25600 specification.

What comes in the box with the HMA81GS6CJR8N-XN kit and what else might be needed?

The kit contains two 8 GB 260-pin DDR4 SO-DIMM modules for a total of 16 GB; no screws, tools or additional cables are included, and nothing else is required if your laptop has two free SO-DIMM slots.

Which capacity version of the HMA81GS6CJR8N-XN should I choose for a dual-channel upgrade?

This part number is only sold as a matched 2 x 8 GB kit totalling 16 GB; select this kit when you need a pair of identical modules to populate two slots for dual-channel operation.
