SKU CH-14QH-3VXP2

A 4 GB DDR4 SODIMM running at 2666 MT/s with 260 pins and 1.2 V operation

  • 4GB capacity adds responsive multitasking headroom
  • 2666 MT/s speed keeps data flowing smoothly
  • 2V operation reduces power draw and heat
  • 260-pin SODIMM fits standard laptop slots
  • 75 ns cycle time enables quick memory access

Single 4 GB DDR4 module

This SK hynix SODIMM delivers 4 GB of DDR4 memory at 2666 MT/s with a 1.2 V operating voltage. The 260-pin form factor fits standard laptop slots and the Non-ECC design targets consumer notebooks. It ships as a single kit in OEM packaging.

Suits basic notebook upgrades

The 4 GB capacity works for everyday browsing, office applications and light multitasking on compatible DDR4 platforms. Users needing higher capacities for content creation, virtualisation or heavy multitasking should look at larger modules or multi-stick kits.

Handles standard office workloads

At 2666 MT/s with a 0.75 ns cycle time the module provides adequate bandwidth for typical productivity tasks. The single 4 GB stick will limit performance in memory-intensive scenarios and leaves no headroom for demanding creative or gaming workloads.

Questions about this item

Will this 2666 MT/s SODIMM work in my laptop that only has DDR4 slots?

The module uses the DDR4 interface and fits a standard 260-pin SODIMM slot, so it will install in any laptop that accepts DDR4 SO-DIMM memory.

Can I add this 4 GB stick alongside the original 8 GB module already in my machine?

Yes, the stick is non-ECC and runs at 1.2 V, matching typical laptop DDR4 specifications, so it can operate in dual-channel with a different-capacity module.

How do I confirm the RAM is running at 2666 MT/s after installation?

Open Task Manager or a tool like CPU-Z and check the reported memory speed; it should show 2666 MT/s (PC4-21300) with a cycle time of 0.75 ns.
