OWC 2S1D42R808GB 8GB DDR4 2133MHz CL15 1.2V 260-pin SODIMM laptop RAM

SKU CH-TDRS-1GK4P

An 8 GB DDR4 SODIMM running at 2133 MHz with CL15 latency and 1.2 V operation for laptops, all-in-ones and NAS units

  • Total capacity8 GB
  • Rated speedDDR4 2133 (PC4 17000)
  • CAS latencyCL15
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Recommended forLaptops, All-in-One Systems, and NAS Systems

Capacity 8GB

  • Boosts multitasking with 8 GB DDR4 capacity
  • Runs at 2133 MHz CL15 for responsive performance
  • Low 1.2 V voltage reduces power draw
  • 260-pin SO-DIMM fits laptops and NAS systems
  • JEDEC compliant for warranty-safe upgrades

8GB DDR4 2133MHz SODIMM Upgrade

This 8GB DDR4 2133MHz CL15 module upgrades laptops, all-in-one systems and NAS devices that accept 260-pin SO-DIMMs. It runs at 1.2V and follows JEDEC PC4-17000 specifications for a warranty-safe installation. The unbuffered, non-ECC design matches the majority of consumer notebook memory slots.

Suitable for standard DDR4 SO-DIMM slots

The module fits systems requiring a single 8GB 260-pin DDR4 stick at 2133MHz with CL15 timing. It is not suitable for machines that require ECC error correction, registered buffering or a different pin count. Buyers needing higher capacities per slot or lower latency ratings should verify their platform requirements first.

260-pin DDR4 SO-DIMM form factor

The decisive specification is the 260-pin DDR4 SO-DIMM form factor combined with 2133MHz speed and 1.2V operation. Only systems built for this exact physical and electrical interface will accept the module.

Questions about this item

Will the 260-pin DDR4 2133MHz CL15 1.2V module run at its rated speed if I keep my existing DDR4 SODIMM in the second slot?

The system will run both modules at the speed of the slowest installed stick; if the existing module is slower than 2133MHz, this OWC module will downclock to match it.

How can I verify the module is running at 2133MHz with CL15 timings after installation?

Open Task Manager on Windows or use a tool like CPU-Z; the memory tab will show the current operating frequency and CAS latency values.

Does the 8GB 260-pin SODIMM come with a heat spreader or any installation tools in the box?

The module has no heat spreader and is shipped as a single stick; no tools are included, only the memory module itself.
