Compatible HP ProBook models

This 2GB DDR3 SODIMM is validated for HP ProBook 4525s, 4530s, 4535s, 4540s and 4545s laptops. It follows the PC3-10600 1333MHz CL9 JEDEC standard and runs at 1.5V without ECC or buffering. The single 1Rx8 rank module fits the 204-pin slot used by these specific notebook platforms. It provides a direct warranty-safe memory upgrade for the listed models.

Suitable for owners of listed notebooks

Users with an HP ProBook 4525s, 4530s, 4535s, 4540s or 4545s can install this module to add 2GB of DDR3 memory. Builders working on other laptop families, desktop boards or servers should look elsewhere because the pin-out, voltage and SPD programming are tailored to these ProBook systems. Buyers who need more than 2GB per slot or require ECC error correction cannot use this part.

Speed grade PC3-10600 CL9

The module operates at DDR3 1333MHz with a CAS latency of CL9, which is the single specification that determines compatibility with the target ProBook chipsets. If your service manual calls for PC3-10600 CL9 1.5V non-ECC SODIMMs, this part matches that requirement exactly. A different speed grade or voltage will not work in these machines.

Questions about this item

Which HP ProBook models must I already own for this 204-pin SODIMM to fit?

This module is validated for HP ProBook 4525s, 4530s, 4535s, 4540s and 4545s laptops.

Can I keep my existing PC3-10600 CL9 stick installed alongside this 1Rx8 module?

Yes, both run at 1333 MHz and 1.5 V so they will operate together in dual-channel mode.

How do I confirm the 2GB DDR3 module is running at 1333 MHz after installation?

Open Task Manager or BIOS and verify the memory speed reads 1333 MHz with CL9 timings.
