fedora core 7 and chcekcing for ram

paul62 · 09-09-2011, 02:51 PM

I have a compaq evod300v how can I check the amount of ram that is being detected with fc7?

Try this in a console:

Quote:

cat /proc/meminfo

to see the status of the memory...

paul62 you are aware that fedora 7 died way back in July 2008 when it hit it's End Of Life

this is the output that I am getting. I would just like to be able to see what my bios is detecting.

is there a simple way to see what the bios is detecting I have 630 mb installed and I would like to be able to verify it.

Ummm...not to kill the fun here, but, as John VV mentionned: FC7 is ... ancient history. Please consider a newer Fedora, or a rolling distro to prevent you ending up with some antique...newer versions are better equipped to handle today's challenges...

Yes there is. At startup, hit the Del key (F10 if it's a Compaq/HP or F2 for a Dell) and look around in the BIOS. Note what's detected and compare...however, and this is an eye-opener:

...and you have...630Mb installed? The memtotal comes about 144Mb more than what you've menionned...

You can also use lshw to check what is installed-
*edit make sure you are running lshw as su/sudo, it returns less info if run as a normal user.

Code:

*-memory
          description: System Memory
          physical id: 25
          slot: System board or motherboard
          size: 4GiB
        *-bank:0
             description: DIMM 1800 MHz (0.6 ns)
             physical id: 0
             slot: A0
             size: 2GiB
             width: 64 bits
             clock: 1800MHz (0.6ns)
        *-bank:1
             description: DIMM 1800 MHz (0.6 ns)
             physical id: 1
             slot: A1
             size: 2GiB
             width: 64 bits
             clock: 1800MHz (0.6ns)
        *-bank:2
             description: DIMM 1800 MHz (0.6 ns) [empty]
             physical id: 2
             slot: A2
             width: 64 bits
             clock: 1800MHz (0.6ns)
        *-bank:3
             description: DIMM 1800 MHz (0.6 ns) [empty]
             physical id: 3
             slot: A3
             width: 64 bits
             clock: 1800MHz (0.6ns)

Here I have 2 x 2GB sticks.

lshw is also handy because it will show you the 'real' amount of installed memory, not 'the amount of installed memory minus any memory shared for onbaord video, etc. use'.

4059612 kB = 3.87GB (OK, 3.87GiB for those that like XiX sizing), not the 4GB that is really installed. That 3.87GB figure is accurate (as far as I know) for what the system can actually use though.
