HP ProBook DDR3 SODIMM Upgrade

This 2 GB DDR3 1333 CL9 module is built for HP ProBook 4330s, 4331s, 4340s, 4421s and 4430s notebooks. It adds 204-pin non-ECC unbuffered memory to systems that accept PC3-10600 SO-DIMMs running at 1.5 V. Buyers who want more storage or need ECC support should look elsewhere.

Simple Laptop Memory Installation

Most ProBook models expose the SODIMM slot under a bottom access panel, so the module drops in without tools. Align the notch, press firmly until the side clips snap, then replace the cover. The usual issue is mixing speeds or capacities; keep all slots identical at 1333 MHz CL9 to avoid boot failures.

DDR3 1333 SO-DIMM Practical Limits

The DDR3 SO-DIMM interface caps at 1333 MHz with 1.5 V operation, so this module cannot run faster or at lower voltage. A single 2 GB stick leaves total capacity limited by the laptop's slot count and chipset maximum. Systems needing higher bandwidth or larger modules require a newer memory generation.

Questions sur cet article

How do I confirm the module is running at 1333 MHz CL9 after installation?

Open the BIOS or a system-information tool such as CPU-Z and verify the memory tab shows DDR3-1333 with CAS latency 9 and 1.5 V operation.

What comes in the box and what must I source separately?

The package contains one 2 GB 204-pin DDR3 SODIMM module; no tools, screws or additional components are included.

Which capacity should I choose for an HP ProBook 4330s?

This part is a single 2 GB module; add a second identical module if your ProBook 4330s has two slots and you want 4 GB total.
