Not to hijack, but I'm looking to max out my laptop with plans of eventually installing Vista 64 Ultimate. I currently have Vista 32 Home Premium. It's a newer HP Pavilion laptop and has two slots, which they claim a max of 4GB. Will 2x2GB sticks WORK on the laptop? I know 32bit OS won't see 4gb total, but they will work until i upgrade the OS to 64 bit right? Sorry for the newb question, just wanna make sure.
