I here the solder-less ones fall off over time and you can do irreversible harm.
ugh this happened to me on my first xbox. I was playing a game and it just up and came off. my xbox gave me some error and red ringed on me. even after opening it up and pulling the chip back in my xbox wouldn't boot. So I took it out and....er same problem.
I know its an xbox and not a ps2 but just be wary with those solderless pieces. like the rest say swap magics the way to go. I myself am ordering a modded ps2 right now, should be good.
