In a chat session with a Dell tech I was informed Dell does not
recommend a processor upgrade. All the pieces must fit and work
together, he said. I have a Pentium III 550 MH and would like to do
better. Is it possible to upgrade and what are the risks/rewards?
Whether you can upgrade a processor depends on the motherboard. Every
motherboard has a limited range of what processors it can accept. Since you
haven't told us what motherboard you have, we can't answer your question
directly. Dell is the best source of that information.
However, even if you could upgrade, it would likely only be a small step up.
You couldn't put a fast modern processor in a motherboard as old as yours.
So that means you also need a new motherboard.
If you get a new motherboard, your old RAM probably won't work in it, so
you'll also need new RAM (and probably more than you had before).
Will the old power supply be adequate for the new motherboard, cpu, and RAM?
You may need a new power supply too.
How about your hard drive? If it's of the same vintage as your 550MHx PIII,
it's probably very small and slow. You probably should upgrade that too
while you're at it.
If you haven't yet seen where this is going, the real point here is that,
rather than upgrade anything, with a computer that old, it's probably best
to discard what you have entirely and buy a whole new computer. You can
probably keep your monitor, and Dell can sell you a new computer that will
run rings around your old one for someplace around $400 or so.
