HP ProBook DDR3 SODIMM Upgrade

This OWC module adds 2 GB of DDR3 1333 memory to compatible HP ProBook notebooks. It uses a 204-pin SODIMM form factor, runs at CL9 latency and operates at the standard 1.5 V JEDEC voltage. The single-rank 1Rx8 design is unbuffered and non-ECC.

Owners of listed ProBooks seeking a simple

The module suits HP ProBook 4431s, 4435s, 4436s, 4440s and 4520s owners who want an easy DIY upgrade. It is not for systems that require ECC or registered memory. Buyers needing more than 2 GB per slot or a different DDR generation should look elsewhere.

2 GB DDR3 1333 CL9 1.5 V SODIMM

The decisive specification is the 2 GB capacity combined with DDR3 1333 CL9 timing at 1.5 V in a 204-pin SODIMM package. Match these figures exactly to your laptop's memory requirements before ordering.

Questions about this item

Should I pick the 2GB module or add a second stick for my ProBook 4431s?

The module is a single 2GB stick; add a second identical module if your ProBook 4431s has a free slot and you want dual-channel bandwidth.

What does the 1333MHz rating deliver in my ProBook 4520s?

The memory runs at DDR3 1333 (PC3-10600) with CL9 latency, giving the maximum JEDEC-standard throughput the ProBook 4520s memory controller supports.

Is the 204-pin SODIMM interface the limiting factor for speed?

The 204-pin DDR3 SODIMM form factor carries the PC3-10600 signal; the ProBook chipset caps the data rate at 1333MT/s, so the slot itself does not restrict performance further.
