What this module is

This is a new 4 GB DDR4 SO-DIMM built to the PC4-19200 standard with CL17 latency and 1.2 V operation. It targets laptop, notebook and all-in-one owners who need a single 260-pin stick to restore or expand system memory.

Who this suits and who should look elsewhere

It fits AMD and Intel platforms that accept unbuffered non-ECC DDR4 2400 MHz memory and have a free SO-DIMM slot. Buyers whose systems require ECC, registered modules, a different pin count, or a larger single-module capacity should look elsewhere.

The specification that decides fit

The 260-pin DDR4 SO-DIMM form factor at 1.2 V determines whether the module will seat and run in a given laptop; verify the platform supports this exact pin layout and voltage before purchase.

Questions about this item

Should I pick a single 4GB stick or add another module for dual-channel?

This listing is a single 4GB DDR4 2400 CL17 SODIMM. If your laptop has two slots, adding an identical stick enables dual-channel bandwidth.

What does the 2400MHz rating deliver in everyday use?

The module runs at DDR4 2400 (PC4-19200) with CL17 timing, giving standard throughput for mainstream laptops and all-in-one systems.

Will the 260-pin DDR4 SO-DIMM fit my laptop's memory slot?

Yes, it uses the 260-pin DDR4 SO-DIMM form factor at 1.2V, matching the physical and electrical spec for compatible notebooks.
