Query: Compatible and worked first time out

Popped this into my Toshiba Satellite M45, and lo and behold, it worked right away! Compatible out of the box. I had 2 x 512MB (1.0 GB total), now have 512MB + 1.0GB = 1.5GB total. Although this didn't speed up the system when I'm only running a couple of applications, when I'm running half a dozen or more simultaneously, the system is quite a bit faster. This allows me to not have to close down applications to get the speed, so I have apps available when I need them without delay.
