I just pay the man at crucial.com.

As to the memory retainer issue, only the top 2 percent of technicians that own and use solder irons might be able to fix that. In fact the more I think about it, I'm going to write ONE in ONE HUNDRED techs. I'm not saying the other 99 are terrible but just like a brain surgeon you won't find them in an emergency room (ie, your usual PC repair shop.)

So go with the name for memory and just use your retainer method to avoid a dead machine.
