    So I recently had my system board replaced, and I *seem* to recall various things reporting MORE memory before the replacement, than before.

    The BIOS says I have 4096MB memory, as I'd expect.

    But when the BIOS prints its diagnostics at startup, it says:

    637K System RAM Passed
    4029M Extended RAM Passed
    System BIOS Shadowed
    Video BIOS Shadowed    ​

    That figure of 4029M is also reported by memtest86+ when I run it.

    Is this the normal set of values for system with 4gb of ram? I'm presuming that the 2 BIOS's and the System RAM take up the 67MB missing from that figure, is that the case?

    Try turning off system and video ram shadowing.

    Unless you're running a 64-bit OS (or PAE, but let's not go there), you won't be able to access more than ~3.2-3.5 GB of RAM anyway (and individual applications are usually limited to 2 GB).
