1GB RAM linux says 905512kB

kule · 02-20-2007, 04:38 PM

I have 2x512MB of RAM, but whe I run:

# cat /proc/meminfo

it tells me that I have 905512kB.

Is this normal, 'cause in winxp it says 1GB RAM.

Well that is nearly 1GB. I guess that WinXP just rounds it up to 1GB.

On my system with 1GB ram, I get

Code:

MemTotal:      1028740 kB

Does anyone else know what could be the problem, cause my linux doesn't use 100MB of RAM which I have

Onboard video or certain low end video cards can steal ram. If you have a nvidia card with turbocache it will steal system memory for its own use. Mine takes 384mb of my system ram.

Alternatively, you mayb just have a bad stick of ram. Run memtest on your computer to check it.

Do you have any shadowing enabled in the bios?
That will lower the amount of physical ram available.

Hello,

maybe you have to adjust the AGP-Aperture in your BIOS.
Sometimes you can find this setting in some hidden/advanced Menu-Entry.
This helped me to free 128MB of RAM

Thanks for the replays, but I didn't compile High Memory Support (4GB).

Everything is working great now.

Very odd. So when you added the high memory support (up to 4GB), then you were able to get your full 1GB? Without the high memory support, Linux only supports less than 1GB?

That's right

It says in the help for High Memory Support, that if you have between 1GB and 4GB of RAM, that you should enable it.
