    So Do I Have a 32 bit or a 64 bit System?


    This laptop has been with me for more than three years already but it is only now I notice this output. Particularly the ones in Bold.

    Code:
    jun@jun:~$ lscpu
    Architecture:          i686
    CPU op-mode(s):        32-bit, 64-bit
    Byte Order:            Little Endian
    CPU(s):                2
    On-line CPU(s) list:   0,1
    Thread(s) per core:    1
    Core(s) per socket:    2
    CPU socket(s):         1
    Vendor ID:             GenuineIntel
    CPU family:            6
    Model:                 15
    Stepping:              13
    CPU MHz:               2166.000
    BogoMIPS:              4322.39
    L1d cache:             32K
    L1i cache:             32K
    L2 cache:              1024K
    jun@jun:~$
    Does this mean I can install say..... an Ubuntu 64 bit in this same machine and add more RAMs and espect my machine to be able to make use of the RAM?

    I read that if my system is 32 bit, it can only make use of 3G RAM and anything extra will not be utilized.

    I have always installed a 32 bit version in this machine and used a 3G RAM. I want to upgrade to 8G if ever.

    Thanks!

    Yes, that means it will operate with a 32-bit OS, or a 64-bit OS. You'll need the 64-bit OS if you install 8 GB of RAM and want it all to be used.

    Even if it turns out to be 32 bit (the op modes suggest it won't) you can install a PAE kernel which will allow it to address upto 64GB RAM although each process will be limited to 4GB.
    What do we want?
    Time machines!

    When do we want 'em?
    Doesn't really matter does it!?

    This is good information even if I don't understand this at the moment!
