  • Non-ECC unbuffered design ensures broad notebook compatibility

Samsung 8 GB DDR4 laptop kit

This Samsung kit supplies 8 GB of DDR4 memory in a matched pair of 4 GB SO-DIMMs. Each module runs at 3200 MHz with a CL22 latency and operates at the standard 1.2 V. The 260-pin form factor fits laptops that accept DDR4 SO-DIMM memory.

Dual-channel configuration

The two-module layout enables dual-channel operation on compatible platforms, doubling the data path compared with a single stick. Ranked as 1Rx16, each module presents a single rank of 16-bit chips, which helps keep signal loading low for stable timing at the rated speed.

Suits mainstream notebook upgrades

This non-ECC kit is aimed at everyday laptops that support DDR4 SO-DIMMs up to 3200 MHz. Systems requiring ECC error correction, higher capacities per slot, or lower latencies should consider alternative modules.

Questions about this item

Will the CL22 latency or 1.2V voltage require any adjustment or replacement down the line?

The modules run at standard JEDEC 1.2V with CL22 timings; no firmware updates or voltage tweaks are needed, and the chips are rated for the full service life of the laptop.

What limit appears first when the kit runs at 3200MHz continuously?

Sustained operation stays within the 1.2V JEDEC envelope, so the first constraint is the laptop's own thermal design rather than the memory itself.

How much heat or noise does the 260-pin SO-DIMM add during all-day use?

The low-voltage DDR4 chips produce minimal heat and have no moving parts, so they add no audible noise and negligible thermal load to the system.
