I need to upgrade RAM on my machine.
I've done this before, but it was ages ago. There were rules or guidelines then as to what could and couldn't be done (some rather obvious) :
- All RAM to be of the same type
- When adding two sticks of RAM to parallel (twinned?) slots, both need to be of the same capacity and preferably of the same manufacturer.
There are lots more types of RAMs and processors now, and I'm not sure what I need to be aware of when I buy new RAM for my machine.
So my question is, what are the rules you know of that I need to follow while upgrading RAM ? Are there dependencies between processor and RAM type, or motherboard and RAM ? Do you know of any downsides to having 4GB RAM on a machine running a 32-bit OS, besides it not recognising the full capacity ? What are the chances I'll be able to use this RAM when I upgrade to a newer CPU/motherboard in future ?
