My computer died and in the interim, until I can get a new one, I'm using my quite old emachines T2245. The RAM is pretty terrible (256mb) so I'd like to upgrade it obviously. The RAM is DDR PC2100. I know nothing about RAM. Can I use the RAM from my old computer, which is DDR PC3200? I presumed not, but when I was looking online to buy upgrades a lot of sites were listing PC3200 RAM as compatible with this computer.
This old computer actually had some issues when I first hooked it up again with the RAM not being connected correctly (was giving me the beeps/not starting up). Perhaps from being moved around/sitting for a few years. I had to go in there and remove it and reconnect it, so I didn't want to mess with it anymore until I knew I had the correct RAM to go in there. If this one dies on me too, I'm stuck with the iphone as my only "computer" for a while...not desirable, haha.
