A-Tech 4 GB DDR4 2400 SODIMM

This A-Tech module delivers 4 GB of DDR4 laptop memory at 2400 MHz with CL17 latency and 1.20 V operation. The 260-pin SO-DIMM format fits standard notebook and all-in-one slots. Major-brand chips and unbuffered, non-ECC design provide a straightforward capacity upgrade for compatible systems.

Suits owners of DDR4 laptops needing a single 4 GB

Buyers whose notebooks require ECC or registered memory cannot use this module. Systems limited to lower DDR4 speeds or different pin counts will not accept it. Machines already at maximum supported capacity or with no free SO-DIMM slot gain no benefit from adding this part.

Deciding specification: DDR4 2400 260-pin SO-DIMM

The module runs at DDR4 2400 (PC4-19200) with CL17 timing at the standard 1.20 V. The 260-pin edge connector and unbuffered, non-ECC layout determine whether the laptop can recognise and use the memory. Verify the platform supports this exact speed, voltage and form factor before purchasing.

Questions about this item

Should I pick the single 4 GB DDR4 2400 SODIMM or look for a larger kit?

This listing is a single 4 GB module at DDR4 2400 CL17; add a second identical stick if your laptop has two slots and you want 8 GB in dual-channel mode.

What does the 2400 MHz rating actually deliver in a laptop?

The module runs at DDR4 2400 (PC4-19200) with CL17 latency at 1.2 V, giving the standard bandwidth and timing for that speed grade.

Does the 260-pin DDR4 SO-DIMM interface limit the speed in any way?

The 260-pin SO-DIMM form factor carries the DDR4 2400 signal natively; the bus caps at the module's rated 2400 MT/s.
