4GB DDR3L 1600 SODIMM for laptop upgrades

This 4GB DDR3L SODIMM runs at 1600MHz with CL11 latency and 1.35V operation. It uses a 204-pin SO-DIMM form factor and unbuffered, non-ECC architecture. The module suits laptops, notebooks and all-in-one systems that accept DDR3L memory.

Replaces specific HP part numbers

The module matches HP part numbers 637233-652, 641369-005, 687515-951, 687515-952, 687515-961, 689373-001, 698656-154 and 854975-800. The upgrade is worthwhile when your system supports DDR3L 1600 and has a free SODIMM slot or can replace a lower-capacity stick.

Simple slot installation with one common pitfall

Installation requires inserting the module into the SODIMM slot at the correct angle until the side clips engage. The most frequent issue is ordering DDR3L for a system that only accepts standard 1.5V DDR3, which prevents the laptop from posting.

Questions about this item

Will the 204-pin DDR3L SODIMM fit my laptop's memory slot?

This module uses the standard 204-pin SO-DIMM form factor for DDR3L laptop memory. Check your system manual to confirm it accepts DDR3L 1.35V modules before purchase.

Which way does the notch on the 204-pin module face during installation?

Align the notch on the module's gold edge with the key in the SODIMM slot, press firmly at a slight angle until seated, then push down until both side clips click.

Does the 1.35V DDR3L module need any special cooling or cleaning over time?

No active cooling or periodic cleaning is required for this low-voltage SO-DIMM. Ensure the laptop's vents stay clear so normal airflow keeps memory temperatures safe.
