SK hynix HMA41GS6AFR8N-TF 8GB DDR4 2133 laptop RAM

8GB DDR4 SO-DIMM for notebooks

This module adds 8 GB of DDR4 memory to a laptop using a 260-pin SO-DIMM slot. It runs at 2133 MHz with a CAS latency of 15 and operates at the standard 1.20 V. The unbuffered, non-ECC design suits mainstream notebook upgrades and replacements.

Straightforward slot installation

Align the notch with the key in the SO-DIMM socket, press the module in until the side clips click, and the firmware will detect the new capacity on the next boot. Problems usually come from mixing speeds or capacities across channels, or from a BIOS that has not been updated to recognise the full 8 GB density.

Steady throughput under load

Rated at PC4 17000 bandwidth, the stick sustains its 2133 MT/s data rate during extended workloads such as large compiles or virtual machines. The 1.20 V supply keeps thermal output modest, so throttling is unlikely in typical laptop cooling envelopes. Single-module configuration means dual-channel bandwidth is not available unless a matching second stick is added.
