In my quest to keep upgrading I was greatly disappointed to see the specs for my 2007 HP Pavillion dv2500 laptop was a maximum of 4GB of RAM. I had already upgraded it to that much, and need to upgrade another laptop in the house – nothing I love more than the opportunity to kill two birds with one stone. Through research I learned that the limit is actually based on your processor chipset, mine an Intel PM965. However both the specs for the chipset, and Crucial still tell me 4GB max. I didn’t believe it and enough of the Googles told me that: chances are it will support 8GB.
Proof is in the picture, slapped them in, started up, and I’ve got 8GB! For RAM I have had the best luck and least problems with Crucial memory, and you can get through Amazon cheaper than crucial.com, and Prime shipping:Crucial CT2KIT51264AC667 8GB (4GBx2) 200-pin SODIMM DDR2 PC2-5300 Memory Module
