13.4MB of memory is missing!
Aloone_Jonez:
I removed the new module and Linux reported 238MB of RAM. I swapped the old module with the new and it still reported 238MB.
Let's see if it's a rounding error as you descried above:
238
Lead Head:
RAM has always been in MiB, and still is (as far as I know), hence why 1GB of ram is advertised as 1024MB
Aloone_Jonez:
That's what I thought.
MiB makes sense when you think of the addressing system on the memory IC.
I don't know though, what else could explain this mystery?
I ran a memtest and it reported 504MB so I assume it's a problem with the kernel as it's the only thing that seems to report a lower figure.
Lead Head:
Do you have an onboard modem/ethernet/sound that could be using some of that ram?
Aloone_Jonez:
I don't know, I would've thought that the BIOS would have taken that into account like it did for my on-board graphics.
I've installed a graphics card now so I'll have a look at the memory reported under Linux next time I reboot.
Windows: Control Panel -> System says 512MB and task manager says 523,760KB which works out just under 512MB but it's an acceptable rounding error.
