CAS Latency CL19

  • 64 GB dual-channel kit expands multitasking headroom for demanding workloads
  • Two 32 GB modules deliver full capacity in a matched pair
  • DDR4 2666 speed reduces load times and improves system responsiveness
  • CL19 latency at 1.2 V balances performance with standard laptop power limits
  • 260-pin SO-DIMM form factor fits compatible notebook and all-in-one systems

Capacity and fit

This A-Tech kit delivers 64 GB of DDR4 memory across two 32 GB SO-DIMM modules. It targets owners of laptops, notebooks and all-in-one PCs that accept 260-pin DDR4 SODIMMs and need a straightforward capacity increase for heavier multitasking.

Build and daily use

Each module is an unbuffered, non-ECC dual-rank x8 part rated at CL19 and the standard 1.2 V. The 260-pin edge connector drops into any compatible SODIMM slot without adapters, and the dual-channel pairing lets the memory controller interleave access for smoother throughput under load.

Compatibility check

Confirm that your system supports DDR4 SODIMMs at 2666 MT/s and can address 32 GB per slot before ordering. Some platforms cap per-slot capacity or limit total memory below 64 GB, so consult the manufacturer’s memory-qualified-vendor list or manual to avoid a mismatch.

Spurningar um þessa vöru

Will the DDR4 2666MHz speed run at its rated frequency or drop lower?

The kit is rated for 2666 MT/s (PC4-21300). It will run at the highest speed supported by the laptop's memory controller, which may be 2666, 2667, or a lower JEDEC standard.

Does the 260-pin SO-DIMM form factor fit my laptop's memory slot?

Yes, these are standard 260-pin DDR4 SO-DIMM modules. They fit any laptop, notebook, or AIO slot designed for DDR4 SO-DIMM memory.

How do I install the two 32GB modules correctly for dual-channel operation?

Power off and unplug the laptop, open the memory compartment, insert each module at an angle into the two SO-DIMM slots until the retention clips click, then reassemble.
