Ready-to-install 8 GB DDR4 module

This 8 GB DDR4 2133 MHz SODIMM delivers 8 GB of memory in a single 260-pin stick. It runs at the standard 1.20 V and uses CL15 latency. The module is unbuffered and non-ECC, matching the Hynix HMA41GS6AFR8N-TF form factor for laptop upgrades.

DDR4 2133 speed ceiling

The DDR4 2133 interface caps data-rate at 2133 MT/s and PC4-17000 bandwidth. Systems limited to lower DDR4 speeds will down-clock the module automatically. Builders needing faster transfer rates must choose a higher-rated DDR4 part because this module cannot exceed its rated frequency.

Single-rank or dual-rank requirement

This module uses a 2Rx8 organisation, meaning it presents two ranks per channel. Laptop memory controllers that accept only single-rank SODIMMs will not recognise the full capacity, so verify the platform rank limit before ordering.

Questions about this item

Should I pick the single 8 GB stick or look for a 2 × 4 GB kit for my laptop?

This listing is a single 8 GB module; if your system has two slots and you want dual-channel bandwidth, buy a second identical stick.

Will the advertised 2133 MHz actually run at that speed in my notebook?

The module is rated for DDR4 2133 (PC4-17000) at CL15; the memory controller in your CPU will set the final frequency, often matching the highest speed it officially supports.

Does the 260-pin SO-DIMM fit every DDR4 laptop slot, and what does PC4-17000 limit?

The 260-pin SO-DIMM is the standard DDR4 laptop form factor; PC4-17000 simply denotes the 2133 MT/s peak transfer rate, so the module will not exceed that bandwidth.
