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.
