CAS Latency CL40

  • 16 GB dual-channel kit expands multitasking headroom
  • DDR5 4800 MT/s delivers higher bandwidth than DDR4
  • CL40 latency keeps data access responsive
  • 1 V operation reduces power draw versus 1.2 V DDR4
  • 262-pin SO-DIMM fits DDR5 laptop slots

DDR5 4800 MHz dual-channel kit

This 16 GB kit contains two 8 GB DDR5 SODIMM modules rated at 4800 MHz with CL40 latency. It runs at the standard 1.1 V and uses the 262-pin form factor required by current laptop platforms. The memory is non-ECC and unbuffered for mainstream notebook use.

Ideal for notebook upgrades needing more capacity

Users who want to run heavier multitasking workloads or keep many browser tabs open will benefit from the extra headroom. The kit is not suitable for systems that only accept DDR4 SO-DIMMs or that require registered or fully buffered modules. Buyers who need error-correcting memory beyond the native on-die ECC should look at server-class hardware instead.

Speed and voltage decide compatibility

The modules operate at DDR5 4800 (PC5-38400) with a fixed 1.1 V supply and CL40 timings. Your laptop must explicitly support DDR5 SODIMMs at this data rate and voltage; otherwise the memory will not function. Verify the manufacturer’s supported memory list before ordering.

Questions about this item

Should I choose the 16GB dual-channel kit or a single 16GB module?

The 16GB kit contains two 8GB modules that run together in dual-channel mode, doubling the data paths compared with a single stick and giving noticeably smoother multitasking on DDR5 laptops.

What does the 4800MHz speed actually deliver in daily use?

At 4800MHz the memory moves data at the standard DDR5 base rate, so apps open faster, large files load quicker, and the system stays responsive when many programs run at once.

How does the 262-pin DDR5 SO-DIMM interface limit performance?

The 262-pin DDR5 SO-DIMM slot caps the kit at the JEDEC 4800MHz 1.1V specification, so it will not run faster unless the laptop BIOS explicitly supports higher DDR5 speeds.
