4GB DDR4 3200MHz SODIMM for HP Laptops

This 4GB DDR4 3200MHz CL22 module is built as a direct replacement for HP part numbers L68529-001, L71643-001 and L83673-001. It suits owners of compatible HP laptops, notebooks or all-in-one systems who need a straightforward capacity increase. The unbuffered, non-ECC design matches the original specification for these platforms.

Low-voltage operation and passive cooling

Running at the standard DDR4 voltage of 1.2V, the module draws minimal power and produces little heat without a heat spreader. Passive cooling keeps the upgrade silent during everyday office work, web browsing and media playback. The single-rank 1Rx16 organisation supports stable operation at the rated PC4-25600 speed.

Steady performance under sustained workloads

The CL22 latency and 3200MHz data rate deliver consistent throughput during extended multitasking or larger dataset handling. JEDEC-standard signalling ensures the module maintains its rated timing without throttling when the system is under continuous load. Compatibility is limited to devices that accept 260-pin DDR4 SO-DIMMs at this voltage and speed.

Questions about this item

How do I install the 260-pin DDR4 SODIMM and what step do people often miss?

Align the notch on the module with the slot key, insert at an angle, then press down firmly until both side clips click; the step often missed is confirming both clips fully engage.

What maintenance or replacement will the 1.2V DDR4 module need later?

No scheduled maintenance is required; replacement is only needed if a memory test reports errors or you want more than the 4GB capacity.

What limit appears first on this CL22 3200MHz module under sustained use?

The 4GB capacity is the first bottleneck, limiting multitasking headroom before thermal or speed limits are reached.
