Four green 260-pin DDR4 SODIMM modules, no heat spreaders

OWC

OWC 64GB (4x16GB) DDR4 3200MHz CL22 1.2V 260-pin SODIMM laptop RAM

SKU CH-5190-135RM

Four 16 GB DDR4 3200 MHz CL22 SODIMM modules provide 64 GB of unbuffered non-ECC laptop memory at 1.2 V

  • Total capacity64 GB (4 × 16 GB)
  • CAS latencyCL22
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Kit configurationDual Channel Kit
  • Recommended forLaptops, All-in-One Systems, and NAS Systems

Capacity 64GB (4 x 16GB)

  • 64 GB total capacity lets you run more apps simultaneously
  • 3200 MHz DDR4 speed transfers data faster for smoother multitasking
  • CL22 latency reduces wait cycles for quicker response
  • 2 V operation lowers power draw and heat in laptops
  • 260-pin SODIMM form factor fits standard notebook memory slots

Capacity and kit layout

This OWC kit delivers 64GB of DDR4 memory across four 16GB SODIMM modules. It is built for laptops, all-in-one PCs and NAS units that accept 260-pin DDR4 SO-DIMMs and can address the full capacity.

Installation requirements

The modules are unbuffered, non-ECC and run at the standard 1.2V JEDEC voltage, so they drop into any compatible slot without extra configuration. No heat spreaders are fitted, leaving maximum clearance for tight chassis designs.

Thermals and power

Operating at 1.2V keeps power draw low and heat output minimal in typical workloads. The bare PCB design relies on system airflow, so noise remains unchanged from the factory cooling solution.

Questions about this item

Will the CL22 latency become a bottleneck during sustained heavy workloads?

The CL22 timing is a standard JEDEC specification for 3200MHz DDR4. Under sustained use the modules run at this rated latency without throttling, so the limit you hit first will be your system's maximum supported capacity or memory-controller bandwidth, not the CAS latency itself.

How much heat and power do four 16 GB sticks draw when the laptop runs all day?

Each module operates at the standard 1.2 V DDR4 voltage with no heat spreader. Total kit power stays within the normal SO-DIMM envelope, and because they are unbuffered non-ECC parts they add minimal thermal load to a typical laptop chassis during continuous operation.

What must my laptop already have for this 260-pin kit to work?

Your system needs four free 260-pin DDR4 SO-DIMM slots and a memory controller that supports 3200 MHz PC4-25600 unbuffered non-ECC memory at 1.2 V. The kit is a matched set of four 16 GB modules, so all four slots should be populated together for best performance.
