8 GB DDR4 laptop memory

This Patriot Signature module provides 8 GB of DDR4 capacity in a 260-pin SO-DIMM form factor. It operates at 2133 MT/s with CL15 timings and a 1.2 V power requirement. The unbuffered, non-ECC design targets standard notebook upgrades.

Suits mainstream notebooks needing a single 8 GB

Ideal for owners of compatible laptops that accept a 260-pin DDR4 SO-DIMM running at 2133 MT/s and 1.2 V. Not suitable for systems requiring ECC, registered modules, speeds above 2133 MT/s or capacities beyond 8 GB per slot.

260-pin DDR4 SO-DIMM at 2133 MT/s CL15

The decisive specification is the 260-pin DDR4 SO-DIMM interface combined with a 2133 MT/s data rate and CL15 latency. Verify that your laptop supports this exact pin count, voltage and speed before purchase.

Questions about this item

Will the 260-pin SO-DIMM slot or the module's PCB height of 1181 mil require any service later?

The module is a non-ECC unbuffered DDR4 SO-DIMM with no moving parts; the 1181 mil PCB height is a fixed physical dimension and the gold edge contacts do not need maintenance.

What limit appears first when the 8GB module runs at 2133 MT/s continuously?

Sustained operation is bounded by the 1.20 V supply and the 7.8 µs refresh interval (8192 cycles per 64 ms) that the DRAM must meet to retain data.

How much heat and power does the 1.2 V DDR4 module produce during all-day use?

The module draws 1.20 V at the rated 2133 MT/s speed; with no fan or active cooling on the stick itself, heat stays within the standard SO-DIMM thermal envelope.
