I just got a kingmax stick of memory from newegg today, but when i brought my pb back to work with the new 1gb stick in my apps have been crashing. CS2 crashed 3 times and mail crashed 1 time. This seems a bit shady to me. I know there is a memtest on the tiger DVD, right? If I put it in, will it boot off the DVD and give me an option to load it there? I need to figure out if thing is bad so I can RMA it.
