SK hynix 8 GB DDR4 laptop module

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

Speed and pin count compatibility

The module runs at PC4-17000 (DDR4-2133) across 260 pins, so the laptop must accept this exact speed and form factor. A system limited to a lower DDR4 rate or a different pin layout will not recognise the stick. Buyers who need a higher frequency or a different capacity should look elsewhere.

Steady thermal behaviour

Rated at 1.20 V, the module maintains its specified latency during extended workloads without requiring extra cooling. The unbuffered architecture avoids added latency that registered designs introduce. Sustained throughput stays consistent as long as the laptop’s own thermal solution handles the system heat.

Questions about this item

How does 2133 MHz DDR4 perform once it is installed in a laptop?

At 2133 MT/s and CL15 the module delivers the standard DDR4 2133 data rate with 15 cycle latency for typical notebook workloads.

What does the PC4 17000 rating actually limit in practice?

PC4 17000 certifies 17000 MB/s peak bandwidth on the DDR4 2133 interface; the laptop's memory controller caps real throughput.

Will the 260 pin SO-DIMM fit my laptop's memory slot?

The 260 pin DDR4 SO-DIMM form factor matches the standard DDR4 laptop slot; physical fit depends on the notebook's slot design.
