Ram issue in OpenSuse

English Install/Boot/Login
#1

Hi,

I have just installed OpenSUSE 12.1 from Live CD. Installation was done on my machine which is having 8GB ram. Eveything went well but when i check the ram consumption using the command free -m.

i got to see that total memory is 3497. I am not able to see the whole memory…

I was previously having ubuntu, it showed completed 8GB Ram, Why is that in opensuse i am having less memory.

You probably installed from the KDE live CD, which defaults to the “default” kernel. Check with


uname -a

to see which kernel you are using.

If you are using the default kernel, then install the desktop kernel and all should be well (after a reboot to the desktop kernel).

Hi
Can you post (in code tags) the output from the command;


dmesg |grep e820

Hi. Have you installed 32-bit or 64-bit?

Hi,

 I have installed the GNOME Live CD. The kernel details are as follows:

Linux -i65x 3.1.0.1.2-default #1 SMP

Please let me know what is the issue. I am looking to use this as a server for my home activities. I am using the correct installation of OPEN SUSE.

The output is as follows:

I was left wondering if you have installed a 32 or 64 bit OS? Now I have installed a custom kernel version, but when I run:

uname -a
Linux LinuxMaster 3.3.1-1.4-desktop #1 SMP PREEMPT Mon Apr 2 20:00:12 CDT 2012 **x86_64 x86_64 x86_64** GNU/Linux

I can see that I am using 64 bit. If I use this command I get:

uname -p
**x86_64**

So lets make sure we know if this is 32 or 64 bit before we proceed. A 32 bit system has around a 4 GB limit minus local memory mapped devices as I recall.

Thank You,

Does your BIOS have a Memory Remap feature … and is it disabled?
3.2Gb out of 4Gb RAM showing in System Monitor

The e830 mapping is finding all 8GB in the usable category as follows:


limits (base 16)      total (base 10)

0 - 9fc00                     654,336
100000 - ddd80000       3,720,871,936
100000000 - 220000000   4,831,838,208

It seems to me that all the memory is found. Is there any other clue in dmesg as
to why it is not all being used? Have you run memtest86+ to see what it finds,
and it it is all usable?

Please krishna_36,

People asked you above to post computer text between CODE tags. They are to polite to ask you again, but you didn’t. And you also did not tell you could not find it or did not understand what it is.

Thus I take the liberty to ask you again: http://forums.opensuse.org/english/information-new-users/advanced-how-faq-read-only/451526-posting-code-tags-guide.htm
