4GB DDR3 1333 SO-DIMM upgrade

This 4GB DDR3 module runs at 1333 MHz with CL7 timing and 1.5 V operation. It uses a 204-pin SO-DIMM form factor and is built with major-brand chips in an unbuffered, non-ECC 2Rx8 configuration. The stick carries the Computer Memory Solutions CM5126410600SODRH part number and is sold as a single-module kit.

For HP Probook 4435S 4436S 4520S 4525S 4530S owners

The module is validated for those specific HP Probook notebooks, making it a direct drop-in upgrade for users of those models. Builders working on other laptop platforms or desktop systems should look elsewhere, as the SO-DIMM form factor and the vendor-verified compatibility list limit use to the named machines.

DDR3 1333 PC3-10600 speed rating

The decisive specification is the DDR3 1333 (PC3-10600) bus speed combined with 1.5 V voltage and CL7 latency. Matching these figures to the host system's memory controller requirements determines whether the upgrade will function correctly.

Questions about this item

Will the CL7 2Rx8 chips need active cooling or replacement in a ProBook 4530S?

The module has no heat spreader and runs at standard 1.5V; DDR3 SODIMMs of this type typically operate for years without maintenance or cooling upgrades.

What sustained-load limit appears first — voltage throttling or CAS timing ceiling?

The stick is rated for CL7 at 1333 MHz and 1.5V; the platform’s memory controller enforces those timings, so the CAS ceiling is the practical limit.

How much extra heat and fan noise does the 4 GB stick add during all-day use?

A single unbuffered 1.5V DDR3 SODIMM adds minimal thermal load; the laptop’s existing cooling handles it without audible fan-speed changes.
