The specs for my laptop is in my sig, and according to the info on newegg, it can only support up to 4gigs of ram, but I'm running Vista Ultimate 64bit. I'm pretty sure it's not possible, but does anyone know from experience if I'd be able to replace the two 2gig sticks it came with with two 4gig sticks to up it to 8gigs? 6gigs even? I priced the rams for it and the prices ain't so bad if I can upgrade it. Plus, it doesn't state how fast my harddrive speed is. Is it possible for me to find out any other way other than calling Acer themselves? I'd like to upgrade this to a 7200rpm drive if it's only 5400 also.
