SAMSUNG 16GB DDR5 4800MHz CL40 1Rx8 1.1V 262-Pin SODIMM laptop RAM M425R2GA3BB0-CQK

SKU CH-8FZE-CJMS0

A 16 GB DDR5 laptop module running at 4800 MHz with CL40 timing and 1.1 V operation

  • Faster data handling with DDR5 4800 MHz speed
  • Lower power draw at standard 1.1 V JEDEC voltage
  • Fits laptops, mini PCs and AIOs via 262-pin SO-DIMM slot
  • Single-rank 1Rx8 layout helps reduce memory bottlenecks
  • Non-ECC unbuffered design keeps compatibility simple for supported systems

Samsung 16 GB DDR5 SODIMM

This Samsung module adds 16 GB of DDR5 memory to a compatible laptop, notebook, mini PC or all-in-one system. It operates at 4800 MHz with a CAS latency of 40 and runs at the standard 1.1 V. The single-rank 1Rx8 design fits a 262-pin SO-DIMM slot and follows the JEDEC DDR5 specification.

Upgraders adding capacity to DDR5 mobile systems

Buyers who need more memory for multitasking or heavier workloads on a supported DDR5 platform can use this module. Systems that require ECC or registered memory cannot use this non-ECC unbuffered part. Desktop computers are not compatible with this SO-DIMM form factor. Check the device manual to confirm DDR5 SO-DIMM support before purchasing.

4800 MHz DDR5 speed rating

The module is rated for 4800 MHz (PC5-38400) operation, which determines the maximum data rate the memory can deliver in a compatible system. This speed sets the performance ceiling for the upgrade. If the platform only supports a lower DDR5 frequency, the module will downclock automatically.

Questions about this item

Does the 262-pin SODIMM arrive alone or with any installation hardware?

The module ships as a single 16 GB stick; no screws, tools or thermal pads are included.

Should I pick the CL40 4800 MHz version or a lower-latency alternative?

This part is only offered at CL40 4800 MHz; choose it when your laptop's manual lists DDR5 4800 support.

Will the advertised 4800 MHz speed actually run at that rate in my notebook?

The stick operates at 4800 MHz / PC5-38400 when the system's memory controller supports that JEDEC speed; otherwise it downclocks to the highest common setting.
