HP ProBook 4GB DDR3 SODIMM upgrade

This 4GB DDR3 1333 PC3-10600 CL9 2Rx8 204-pin 1.5V non-ECC SODIMM is built for HP ProBook 4720s 4730s 4740s 5310m and 5320m laptops. It adds a single JEDEC-standard memory module to increase capacity for everyday multitasking. The module is designed to meet or exceed the original manufacturer specifications for these systems. Buyers who need more than 4GB of memory or who use a different laptop model cannot use this upgrade.

Simple SODIMM installation for listed ProBooks

Installation requires opening the memory compartment on the underside of the compatible ProBook and inserting the 204-pin module until it clicks into place. No tools beyond a small screwdriver are typically needed and the process takes only a few minutes. Problems arise if the slot is damaged or if the notebook BIOS does not recognise the 2Rx8 rank configuration. Systems outside the listed ProBook series will not accept this module mechanically or electrically.

Steady operation under continuous workloads

The module runs at the standard 1.5V DDR3 voltage and CL9 latency without a heat spreader, relying on the laptop chassis airflow for cooling. During extended multitasking or large-file editing the memory maintains its rated 1333MHz speed because it is validated to JEDEC specifications. Sustained performance is limited by the single 4GB capacity and the DDR3 platform bandwidth ceiling.

商品問答

How do I confirm the OWC 4GB DDR3 1333 CL9 module is running at the correct speed after installing it in my HP ProBook 4730s?

Enter the BIOS or use a system-information tool such as CPU-Z; the memory tab should show DDR3-1333 (PC3-10600) at CL9 with 1.5 V and a single 204-pin SODIMM detected.

What comes in the box with the OWC 4GB DDR3 1333 SODIMM and is anything else required for installation in an HP ProBook 5320m?

The package contains one 4 GB 204-pin DDR3 Non-ECC SODIMM (part 1S3D32R804GB); no extra parts or tools are needed — just open the memory slot cover and insert the module.

Which capacity version of this OWC DDR3 1333 SODIMM should I choose if my HP ProBook 4740s has two slots and I want 8 GB total?

Buy two of the 4 GB modules (part 1S3D32R804GB) to reach 8 GB across both slots; each stick is a single 4 GB 2Rx8 SODIMM rated at PC3-10600 CL9.
