How do you tell if RAM is compatible

I've two laptops, a old one and a new one. The new one is overall good except it has virtually no RAM, my old one is nackered but has a gb of RAM in it. How can I tell if the RAM from the old would be compatible in the new?

I'd suggest running the Crucial scanner on each, see what results it comes back with - it'll tell you what kind of memory is right for each machine. If there's more than a couple of years difference between the two laptops, I'd be surprised if the memory was compatible - but you never know.

The ram will most likely have a sticker on it with information e.g.

PC2700

512MB DDR 333Mhz CL2.5

Size type speed latency

type and latency must match with what you already have

there is a notch in the contacts at the bottom if the RAm is wrong type then the notch will be in a different spot i.e. a third of the way along or central. This stops you trying to physically fit the wrong RAM
