    Its most likely 1GB but some might be used for onboard graphics or just the way Linux has sliced it up

    1GB is 1048576KB, so your figure is 76932 (~75MB) short of that. It is normal for the OS kernel to reserve some memory for itself that doesn't get counted in the total displayed by commands like "free", though a quick check on a 1GB server I have access to shows a descepency of only ~20MB so 75 might be a little high.

    I say "might be" rather than "definitely is" a little high, as this is likely to be very dependent on your kernel configuration. I would expect it to be higher if you had a large monolithic kernel rather than a modularly compiled one, for instance.

    Also, some systems claim some main-board RAM for the graphics chip-set instead of it having RAM of it's own. It is not unlikely that your graphics controll has been given 64MB of main-board RAM and the remaining 11Mb is what the Kernel has statically claimed.

    just not understand... my friend setup a server with 1gb and in SSH it shows:
    ===============
    total 8.9% 2.8% 3.7% 0.4% 1.8% 82.1% 0.0%
    Mem: 971644k av, 942352k used, 29292k free, 0k shrd, 61640k buff
    614548k active, 265780k inactive
    Swap: 1959920k av, 0k used, 1959920k free 548700k cache
    ==============

    whyle i have a server with 1gb and it shows:
    =============

    Mem: 1048576k av, 361240k used, 687336k free, 0k shrd, 0k buff
    0k active, 0k inactive
    Swap: 0k av, 0k used, 0k free 0k cached
    =============

    think there is somehting wrong...

    usually it is less than what is in your system. THis could be reserved memory for system, etc.. but yeah 1024MB = 1GIG

    942352 + 29292 + 61640 = 1033284

    1033284 / 1024 = 1009MB

    Other 25MB probably Kernal related...
