4GB DDR3 SODIMM for laptop upgrades
This 4GB DDR3 1600MHz module adds memory capacity to compatible notebooks and all-in-one systems. It targets users who need a straightforward capacity increase for everyday multitasking and smoother application loading. The single stick installs into an available 204-pin slot. Buyers who want more storage or a faster memory standard should look elsewhere.
Unbuffered 1.5V stick with major-brand chips
The module uses major-brand DRAM components on an unbuffered, non-ECC PCB rated at 1.50V standard voltage. Its 204-pin SO-DIMM edge connector matches the physical slot found in many DDR3-era laptops. CL11 latency and PC3-12800 bandwidth deliver the expected timing for this generation. Systems requiring registered or ECC memory cannot use this stick.
Replaces HP part numbers 641369-001 B4U39AA B4U39AT
This module serves as a direct equivalent for the listed HP part numbers, simplifying the search for a compatible upgrade. The jump is worth it when your current configuration leaves headroom for an additional 4GB and the platform supports DDR3 1600 operation. Verify your system's maximum supported capacity and slot count before ordering.

Questions about this item
Does the DDR3 1600 PC3-12800 interface limit the module to 1600 MHz in a laptop that supports higher speeds?
The module runs at 1600 MHz PC3-12800; a faster-capable system will down-clock it to this speed.
Will the 204-pin SO-DIMM fit a standard laptop memory slot without an adapter?
Yes, the 204-pin DDR3 SO-DIMM form factor matches the standard laptop slot exactly.
Is there a notch or key position I must align when inserting the stick, and which way does the label face?
Align the off-centre notch with the slot key, press in firmly until the side clips click, label side up.
