Color Black

  • 8 GB capacity lets you run more apps at once
  • 2133 MHz DDR4 speed delivers responsive everyday performance
  • 2 V operation reduces power draw compared to DDR3
  • CL15 latency keeps data access quick for smooth multitasking
  • 260-pin SODIMM fits compatible laptops, notebooks and all-in-ones

Capacity and Form Factor

This Timetec module delivers 8 GB of DDR4 memory in a 260-pin SODIMM package built for laptops, notebooks, mini PCs and all-in-one systems. It operates at 1.20 V with a CAS latency of CL15 at the rated 2133 MHz speed.

Build Integration

The stick plugs directly into a standard DDR4 SODIMM slot without extra cables or configuration, making it a straightforward capacity upgrade. It is not compatible with desktop DIMM slots, so the module must go into a mobile or compact platform that accepts 260-pin memory.

Speed and Headroom

At 2133 MHz the module supplies PC4-17000 bandwidth suited to everyday multitasking, office applications and light content workloads. Systems requiring higher frequencies such as 2400, 2666 or 3200 MHz will run this stick at the lower supported speed, limiting peak throughput.

Questions about this item

Will the 1.2V voltage limit the module under sustained heavy workloads?

The module runs at the standard DDR4 1.2V, so voltage is not a limiting factor during sustained use.

How much heat and noise does the CL15 SODIMM produce when running all day?

Memory modules have no moving parts and generate minimal heat; they operate silently in a laptop chassis.

Does my laptop need a 260-pin DDR4 SODIMM slot to use this 8GB stick?

Yes, the module requires a 260-pin DDR4 SODIMM slot and is not compatible with desktop DIMM sockets.
