HP ProBook memory upgrade

This 2 GB DDR3 SODIMM is built for HP ProBook 4720s 4730s 4740s 5310m and 5320m notebooks. It adds 2 GB of PC3-10600 memory at 1333 MHz with CL9 latency. The module is unbuffered non-ECC and runs at 1.5 V. Buyers who need more than 2 GB per slot should look at higher-capacity kits.

Thermals noise and power

The stick has no heat spreader and draws power only through the 204-pin socket at the rated 1.5 V. Passive cooling inside the laptop chassis handles the thermal load without extra fan noise. Power consumption stays within the standard DDR3 envelope for this speed grade.

Compliance and installation help

JEDEC and RoHS compliance make the upgrade warranty-safe for the listed ProBook models. OWC supplies a limited lifetime warranty with free technical support and an advanced replacement programme. An online installation video guides the DIY fitting process.

Questions about this item

How do I install this 204-pin SODIMM in my HP ProBook 4730s and which step do people often miss?

Power off the laptop, remove the battery, open the memory access panel, insert the module at a 30-degree angle until the gold contacts are hidden, then press down firmly until both side clips click into place. The step many skip is verifying the clips have fully locked on both sides.

What maintenance or replacement will this DDR3 module need over time?

No scheduled maintenance is required for the memory itself. Keep the laptop's cooling vents clear of dust so the module stays within its 1.5 V operating envelope. Replacement is only necessary if you need more than 2 GB of capacity or if a module fails.

What limit appears first when this CL9 1333 MHz SODIMM runs sustained workloads?

The 2 GB capacity ceiling is reached before any thermal or timing limit. With only 2 GB available, the system will swap to storage during heavy multitasking long before the DDR3 1333 CL9 module hits its voltage or temperature boundaries.
