Two green DDR4 SO-DIMM sticks with black chips, no heat spreader

OWC

OWC 64GB (2x32GB) DDR4 3200MHz CL22 2RX8 SODIMM 1.2V 260-pin laptop RAM

SKU CH-AD1J-C4Q3G

A 64GB dual-channel DDR4 3200MHz CL22 SODIMM kit for laptops, all-in-ones and NAS systems

  • Total capacity64 GB (2 × 32 GB)
  • CAS latencyCL22
  • Rated voltage1.2 V
  • Buffer typeUnbuffered
  • Kit configurationDual Channel Kit
  • Recommended forLaptops, All-in-One Systems, and NAS Systems

Capacity 64GB (2 x 32GB)

  • 64GB dual-channel kit enables heavy multitasking and large-file workflows
  • 3200MHz CL22 timing delivers responsive system performance for everyday tasks
  • 2V DDR4 operation reduces power draw and heat in thin laptops
  • 260-pin SO-DIMM form factor fits standard laptop and all-in-one slots
  • JEDEC-compliant modules ensure broad compatibility and stable operation

Upgrade Kit for Laptops and NAS

This OWC kit supplies 64 GB of DDR4 memory across two 32 GB SO-DIMMs rated at 3200 MHz with CL22 timings. It targets owners of compatible laptops, all-in-one PCs or NAS units who need more capacity for multitasking and larger workloads. The dual-channel configuration helps the memory controller move data efficiently.

JEDEC Compliant 260-Pin Modules

Each stick follows the JEDEC standard for DDR4 SO-DIMMs and runs at the standard 1.2 V without heat spreaders. The 260-pin edge connector fits the SO-DIMM sockets found in most modern notebooks and compact systems. Unbuffered, non-ECC design keeps installation straightforward for a typical DIY upgrade.

Low Voltage Operation in Confined Spaces

At 1.2 V the modules draw modest power and generate limited heat inside tight chassis where airflow is restricted. CL22 latency at 3200 MHz delivers stable throughput for everyday workloads without increasing thermal load. The absence of a spreader means the modules rely on case airflow, which is normal for factory SO-DIMM slots.

Questions about this item

What does the DDR4 PC4-25600 3200MHz CL22 rating mean for real-world speed?

The kit runs at 3200MHz with CL22 latency under the JEDEC PC4-25600 standard, so it will operate at that speed when the laptop’s memory controller supports it.

Will these 260-pin SO-DIMMs fit my laptop’s memory slots?

Each module is a standard 260-pin DDR4 SO-DIMM without a heat spreader, matching the form factor used in most laptops, all-in-one PCs and compatible NAS units.

How do I install the two 32GB sticks correctly?

Power off the system, open the memory compartment, align each module’s notch with the slot key, press firmly until the side clips click, then verify 64GB is recognised in BIOS.
