Two green SO-DIMM modules with black chips and gold contacts

SAMSUNG

SAMSUNG M471A1K43CB1 16GB (2x8GB) DDR4 2400MHz CL17 laptop RAM

SKU CH-FJSC-HHXWZ MPN M471A1K43CB1

Two 8 GB DDR4 SO-DIMM modules running at 2400 MHz CL17 for 16 GB total laptop memory

  • 16 GB dual-channel kit upgrades multitasking headroom
  • DDR4 2400 MHz PC4-19200 bus speed accelerates data throughput
  • CL17 CAS latency tightens response times
  • 2 V operation reduces power draw and heat
  • 260-pin SO-DIMM form factor fits standard laptop slots

Kit contents and target users

This Samsung kit provides 16GB of DDR4 laptop memory using two 8GB SO-DIMM modules. It suits owners of compatible notebooks who need to reach 16GB total capacity or replace a failed stick. Builders requiring more than two slots or higher frequencies should look elsewhere.

Build details and daily handling

Each module uses a 260-pin SO-DIMM form factor with a 1Rx8 single-rank layout and runs at 1.2V. The gold-edge connector slots into standard DDR4 laptop sockets without tools. Non-ECC operation means the kit works in mainstream consumer notebooks that do not support error-correcting memory.

Compatibility checks before ordering

Confirm your laptop accepts DDR4 SO-DIMMs at 2400MHz with CL17 timing and 1.2V voltage. Verify the board has two free slots or can replace existing modules to reach 16GB. Cross-reference the listed part numbers such as PC4-2400T-SA1-11 or 862398-856 against your service manual.

Questions about this item

Does the PC4-19200 rating limit the kit to 2400 MHz on a laptop board?

Yes, the kit is specified at 2400 MHz and will run at that speed when installed in a compatible slot.

Will the 260-pin SO-DIMM modules fit a standard laptop memory slot?

The 260-pin SO-DIMM form factor matches the standard DDR4 laptop slot, so the modules seat directly without an adapter.

What is the correct way to seat the modules, and what step is often missed?

Align the notch with the slot key, press firmly until the side clips click, and verify both sticks are fully latched; the step often missed is pressing hard enough to engage both clips.
