unfortunately it didn't recognise my laptop or its motherboardi don't see the max ram supported in the user manual nor anywhere else i can find.
try going to crucial and running their memory scanner from this page. it should be able to tell you the max supported and type of ram you can use.
those websites couldn't recognise my laptop .. cpu-z didn't tell me the max capacity tooRam vendors like Kingston or crucial have ram upgrade apps.
You enter the specific make/model of your laptop and you will get a list of supported upgrades.
Buy one of those, or at least the exact same specs from a different vendor.
Or, install and run cpu-Z
On the SPD tab, it will identify what ram slots you have and what is populated in them.
Laptops commonly only have two slots so you should be looking for a 2 x 4gb ram kit as a complete replacement.
