My computer came with 256 MB of pc 133, and I then put another 256 MB of pc 133 ram in it. When I unplug my computer and turn it on, it reads like 480 MB of RAM, but if I unplug it again, and then turn it on, it will read 512 MB. This happends everytime I unplug my system. Once it reads 512, it is fine until the system is unplugged again.
