Very informative, thank you dc3
Herk. Yes, it can be a minefield. I told my supplier of my specs and the item I wanted, and asked him to confirm before he sent. This was the reply: "Hi Rob, It should be OK but I can't guarantee it and our supplier wont take back value ram unless its faulty. It is only guaranteed if you go with the Ram specified by Kingston for your model. Unfortunately I have looked on the Kingston site and they haven't tested your model but some close, This is what Kingston Ram recommend for both HP/Compaq Presario Notebook F553US and HP/Compaq Presario Notebook F555AU http://www.ec.kingston.com/ecom/configurat...;submit1=Search KTH-ZD8000A/256 256MB DDR2-533 Module

My reply was: "Thanks for that Tony. HP's part no. is 443489-001. Everything about the valueram checks out in the way of being DDR2 and PC2-4200 configuration so I guess we can chance it. At that price, who cares anyway. This is the first laptop I have ever bought, but with Vista and 512MB I can't get over how slow it is compared to my new Pavilion desktop, so the extra RAM should make a bit of difference.

] Now come on - they can't have it both ways. LOL. Cheers"
I thought it was very funny, but everything worked out well. You can't be too careful though.
