SAMSUNG M471B5673FH0-CH9 4GB (2x2GB) DDR3 1333 laptop RAM

What this kit adds to a laptop

This Samsung kit supplies four gigabytes of DDR3 laptop memory as two 204-pin SO-DIMM modules. Each stick is rated at 1333 MHz under the PC3-10600S standard and runs at the standard 1.50 V. The modules are unbuffered and non-ECC, matching the requirements of most mainstream notebooks that accept DDR3 SO-DIMM memory.

Check your notebook before ordering

Verify that the machine uses DDR3 SO-DIMM slots and supports 1333 MHz operation at 1.50 V. Confirm the motherboard accepts unbuffered, non-ECC modules and has two free slots for the pair. Some ultra-thin or older designs limit maximum capacity per slot, so consult the service manual for the exact per-slot ceiling.

Behaviour during extended use

Under sustained workloads the modules operate within the JEDEC 1.50 V specification, so heat output remains consistent with standard DDR3 SO-DIMM envelopes. No onboard thermal sensors or heat spreaders are present, so case airflow determines peak temperature. Stability over long sessions depends on the platform's memory controller maintaining rated timings without additional voltage headroom.
