4GB DDR4 2400MHz SODIMM Upgrade

This 4GB DDR4 260-pin SODIMM module operates at 2400MHz with a CL17 latency and 1.20V voltage. It is an unbuffered, non-ECC memory upgrade built with major brand chips for laptop, notebook and all-in-one systems.

For single-slot capacity boosts

The single 4GB stick suits owners of compatible HP platforms such as 854915-001, Y7B55AA, Z4Y84AA, Z9H55AA and Z9H55AT who need a straightforward capacity increase. Builders requiring larger single-module densities, ECC error correction or registered buffering should consider other options.

260-pin DDR4 SO-DIMM form factor

The module uses the 260-pin DDR4 SO-DIMM interface, which determines whether it physically fits and electrically functions in the target notebook. Verify the system's supported memory specification before purchase to ensure compatibility.

商品問答

Does the 260-pin DDR4 SO-DIMM fit a standard laptop memory slot?

Yes, it matches the standard 260-pin DDR4 SO-DIMM form factor used in compatible laptops, notebooks and all-in-one systems.

How do I install the 260-pin module and what step is often missed?

Align the notch on the gold edge with the slot key, insert the module, then press down evenly until the side retention clips snap into the notches on both sides.

Will the 1.20V CL17 module need any future maintenance or replacement?

No scheduled maintenance is required; the module is tested for reliability and covered by a lifetime warranty if a fault ever develops.
