System-Specific DDR2 Upgrade Kit

This 4 GB kit contains two 2 GB DDR2-667 SO-DIMMs built for HP Pavilion dv9500 series notebooks. The modules run at 1.8 V with CL5 5-5-5 timing and use unbuffered, non-ECC chips on a 200-pin PCB. Computer Memory Solutions validates compatibility with the dv9500t, dv9500, dv9500Z and dv9501tx models.

Owners of Listed HP Pavilion Notebooks

The kit suits users whose dv9500-series laptop accepts DDR2 SO-DIMMs and has two free slots for a 4 GB total. Buyers whose machine requires DDR3 SO-DIMMs cannot use these modules because the pin layout and voltage differ. Systems already at the 4 GB maximum or with only one slot will not benefit from the second stick.

DDR2-667 (PC2-5300) Speed Rating

The decisive specification is the DDR2-667 speed grade, also marked PC2-5300. Only notebooks designed for this exact DDR2 rate will recognise the modules at full frequency; faster or slower DDR2 standards are not supported by this part number.

Questions about this item

My HP Pavilion dv9500 has two memory slots — will this 2 x 2 GB kit fill both of them?

Yes, the kit contains two 200-pin DDR2 SO-DIMM modules and the compatible systems listed have two sockets with a maximum of 4 GB total, so the kit fully populates the machine.

I plan to keep the original PC2-5300 stick already in the laptop — will this CL5 kit run stably alongside it?

Both the existing module and this kit are rated DDR2 667 (PC2-5300) with CL5 5-5-5 timing at 1.8 V, so they will operate at the same speed and voltage without manual adjustment.

After installing the two modules, how can I confirm the system recognises the full 4 GB at the correct 667 MHz speed?

Open Task Manager or the BIOS memory information screen; it should show 4 GB total capacity, DDR2 type, and a running frequency of 667 MHz.
