Targeted DDR3 Upgrade

This 2GB DDR3 1333 SODIMM is built specifically for HP ProBook 4230s, 4310s, 4320s, 4325s and 4326s notebooks. It provides a direct memory increase for owners of those models who need more capacity for everyday multitasking.

JEDEC Standard Build

The module follows JEDEC and RoHS specifications at 1.5V with CL9 latency and a 1Rx8 unbuffered layout. Its 204-pin SODIMM form factor fits the factory memory slot without adapters, and the lack of a heat spreader keeps the profile low for tight chassis clearance.

DDR3 Platform Limits

DDR3 memory tops out at the 1333 MT/s speed rating used here, so bandwidth cannot scale beyond this interface. The single 2GB density also caps total capacity per slot, which may restrict users running memory-intensive workloads or newer operating systems.

Questions about this item

What speed does the DDR3 PC3-10600 interface actually run at?

The module operates at 1333 MHz with CL9 latency, which is the native data rate for the PC3-10600 standard.

Will this 204-pin SODIMM fit the memory slot in my HP ProBook 4320s?

Yes, the 204-pin form factor matches the DDR3 SODIMM slots used in the ProBook 4230s, 4310s, 4320s, 4325s and 4326s.

How do I install the module, and what step do people often miss?

Power off the laptop, remove the battery, open the memory door, align the notch on the 204-pin module with the slot key, press firmly until the side clips snap shut, then replace the door and battery before booting.
