Subject: [gentoo-user] Kernel doesn't use all of the available memory
Date: Thu, 09 Dec 2010 22:24:34 +0100	[thread overview]
Message-ID: <1291929874.17444.0@numa-i> (raw)

Hi,

I see a strange effect which puzzles me.
I have two AMD64 (~amd64) Systems. Both have 8Gb memory installed
as reported by their BIOS as well as by lshw.
One is a somewhat older Opteron, the other one a recent Phenom II.
But the output of 'free -m' differs significantly

On the Phenom II       there a total of 7738 Mb
but on the old Opteron there a total of 6477 Mb only.

The 2.6.36 kernel is configured nearly identical (just a different SATA 
driver).

Has anybody an idea where this comes from?

Many thanks for a hint,
Helmut.
