RAM upgrade impossible?

Hello,

are more than two GB of RAM unusable?

We have two 2 GB RAM modules inserted and the BIOS recognizes 4 GB but ASG shows only 2 GB.


# dmesg|grep -i mem (after reboot)

3200MB HIGHMEM available.

896MB LOWMEM available.

  HighMem zone: 819200 pages, LIFO batch:31

Memory: 2056716k/4194304k available (1720k kernel code, 39040k reserved, 647k data, 172k init, 1179584k highmem)

Freeing initrd memory: 2061k freed

Freeing unused kernel memory: 172k freed

ASG 7.404

Any ideas?

Thanks!

That's probably 2GB _per process_.

type 'free' to check available RAM.

It is a dual cpu system.

What exactly do you mean with per process?

Hi,
more importantly is it a user built ASG or an Astaro hardware/software package?

Some motherboards will only recognise part of a 4gb system eg my HP laptop recognises 2811mb out of the 4gb installed, not impressed.

Strange; dmesg shows 3.2gb but then only 2gb are available.

Can anyone else post the output of 'free' on a 4gb Astaro system?

We located the problem at the bios. SoftwareMemory hole was activated. After disabling, ASG recognizes 4 GB how it should.

Thanks for all.

But another question: Is ASG a PAE Kernel using, so we could use above 4 GB RAM ???

Greetings

Astaro hasn't yet had a PAE kernel, unless the new beta has one (I'm running it but unsure how to test for PAE).
uname -a does NOT show pae.
