Targeted upgrade for HP ProBook 4545s

This 16GB kit contains two 8GB DDR3 SODIMM modules built for the HP ProBook 4545s and ProBook 4540s. It raises the notebook to its maximum supported memory so multitasking and larger datasets stay in fast RAM instead of paging to storage.

Passive operation at 1.5 volts

Unbuffered, non-ECC modules run at the standard DDR3 1.5V without a heat spreader, so they add no active cooling noise and draw minimal power from the laptop’s battery. The CL9 9-9-9 timing delivers the rated 1333 MHz speed within the platform’s thermal envelope.

Drop-in 204-pin SO-DIMM pair

Each stick uses the 204-pin SO-DIMM form factor that matches the factory slots, so installation requires only opening the memory door and seating both modules. The kit occupies both DIMM sockets, leaving no free slot for further expansion. Buyers who want more storage capacity or a different memory generation will need a different platform.

Questions about this item

How do I install the 204-pin DDR3 SODIMM modules in the ProBook 4545S, and what step is often missed?

Power off the laptop, remove the battery, open the memory door, insert each module at a 30-degree angle until the gold contacts disappear, then press down firmly until both side clips click — the click is the step many forget.

What maintenance or replacement will this 16GB kit need over time?

No routine maintenance is required; the modules carry a limited lifetime warranty against manufacturing defects, so replacement would only occur if a stick fails and is exchanged under that warranty.

What limit appears first when the ProBook 4545S runs sustained workloads with this 1333 MHz memory?

The memory bandwidth ceiling of PC3-10600 at CL9 1.5 V becomes the bottleneck before thermal throttling, since the unbuffered 2Rx8 SODIMMs have no heat spreader to dissipate prolonged heavy traffic.
