32GB DDR4 3200 SO-DIMM kit

This kit provides 32GB of DDR4 laptop memory as two 16GB modules. Each stick uses the standard 260-pin SO-DIMM form factor and runs at 3200 MT/s (PC4 25600). The product is new and manufactured by Black Diamond Memory.

Speed rated at DDR4 3200 (PC4 25600)

The modules operate at 3200 MT/s with a PC4 25600 data rate. This speed rating is the primary specification that determines whether the kit matches the notebook's memory controller requirements.

Questions about this item

Does the DDR4 3200 speed stay stable under sustained laptop workloads?

The modules run at DDR4 3200 (PC4 25600) with standard JEDEC timings; sustained stability depends on the laptop's memory controller and cooling.

How much heat or noise do these SO-DIMMs add when the system runs all day?

DDR4 SO-DIMMs have no moving parts and draw low power, so they add negligible heat and zero audible noise during continuous operation.

What must the laptop already have for this 260-pin kit to work?

The notebook needs two free DDR4 SO-DIMM slots that accept 260-pin modules and a memory controller compatible with DDR4 3200 speeds.
