Purpose and audience

This 4GB DDR3 SO-DIMM is built as a direct replacement for the HP 641369-002 module. It suits owners of compatible laptops, notebooks or all-in-one systems who need a straightforward memory upgrade to improve multitasking and application responsiveness.

Deciding specification

The module runs at DDR3 1600 (PC3-12800) with CL11 latency at 1.50V, using a 204-pin unbuffered non-ECC design. Systems that require a different voltage, pin count, speed grade or ECC support will not accept this stick, so verifying the exact memory specification of the target machine is essential before purchase.

Build integration

The stick installs in a standard DDR3 SO-DIMM slot and draws power at the standard 1.50V level without additional cooling or configuration steps. It adds 4GB of capacity in a single module, leaving any second slot free for a matching stick if the platform supports dual-channel operation.

Questions about this item

What does the 1600 MHz speed mean once the module is installed in a laptop?

The module will run at up to 1600 MHz if the laptop’s memory controller supports that frequency; otherwise it will downclock to the highest speed the system allows.

What interface does the 204-pin SO-DIMM use and what does it limit in practice?

It uses the DDR3 SO-DIMM interface, which caps the maximum data rate to 1600 MHz and the voltage to 1.5 V on this module.

Will the 204-pin SO-DIMM fit a standard laptop memory slot?

Yes, the 204-pin SO-DIMM form factor matches the standard DDR3 laptop memory slot found in compatible notebooks and all-in-one systems.
