Go to http://www.crucial.com run the system scanner tool to identify the machine. They will make recommendations at a reasonable price. ;-)

To find your specific model number or specific Product Number....

Go here:

Scroll down a bit.

Find the similar label on the outside of the computer's case.
- the specific model number - is at the end of the first line
- the specific Product Number - p/n - is on the third line

The Product Number is usually only useful on the HP web site.
If you search the HP web site with the Product Number, don't use the last part of it - # and the characters after it - to search with.

If you don't get a specific result on the HP web site when you search using the specfic model number or the Product Number, the country setting for the HP web site needs to be changed. If you search on the web using the specfic model number, at least one of the "hits" will be for the support of that model on a HP web site that IS set to the correct country, or that IS set to a country in the same region.

You can search search for ram that is listed for your mboard (that is compatible with it) on any ram manufacturer's or ram distrbutor's web site that allows you to search for ram by using the make and model of your brand name system, or the make and model of the mboard if it's a generic desktop system. The Crucial web site is just one of them. Those web sites often have somewhere where you can have their ram that is compatible with your mboard auto detected, if and only if the subject computer is the one that is accessing the web site.

Once you know the part numbers of brand name ram modules that are listed for your computer model, you can buy the ram from anywhere that has that/those part number(s).

Note that some ram is available that is specfied to use a non-standard higher ram voltage, e.g. DDR2 PC-6400 800mhz ram or faster. All the specs for all ram modules installed should specify it uses the same ram voltage - that's often printed on a stuck on label on the modules.

The model number should be on a tag on the underside of the laptop.
