I have 2 256 MB Dimms, for a total of 512 MB. System Properties shows the
full 512. However, the System Information utility shows only 384MB Total
Physical Memory. The difference is 128MB, half of one Dimm. The POST
memory check seems to be seeing the full amount. Task Manager sees the full
amount also. I ran a memory tester I downloaded from Microsoft, and it
didn't get any errors, although I couldn't tell how much memory it was
testing.

Is this normal?

Thanks for any help.
