Physical Memory not recognized by the PAE Kernel

What video chip do you use?

Hi,

my video chip is Intel GMA 950 with 256-bit graphics core with dynamic video memory technolgy up to 128 MB, 32 bit color depth;

my Chipset is:
Northbridge: Intel 945GM;
Southbridge: ICH 7-M

fujitsu official forum says that my chipset supports up to 4GB of ram (http://forum.ts.fujitsu.com/Forum/viewtopic.php?f=93&t=39275)

What is the output of:

uname -a; lsb_release -a

Thanks

No LSB modules are available.
Distributor ID: Ubuntu
Description: Ubuntu 11.10
Release: 11.10
Codename: oneiric

P.S. I had to downgrade to ubuntu 11.10 for problems with wistron_btns

Thats not the PAE kernel, so the maximum the kerne will see is 3.2Gb, minus the 128Mb for your onboard video and things add up nicely.

Just so you are aware, Oneiric has less than a few weeks support left. I suggest you upgrade to Precise soon and you will then be supported til April 2017.

ok,

now i upgrade to Precise Pangolin 12.04,2 LTS but I do not think this solves the problem.

Install the PAE kernel. What CPU do you use?

cat /proc/cpuinfo

Will tell you.

ok upgraded to 12.04.02

I restarted the system and I loaded linux-generic-pae 3.2.0.39

but in system settings - details, memory shows 2,9 GiB

I found a document which explains the reason why the 32-bit operating system sees 2.99 GB despite 4GB of physical memory installed : http://www.dcomputer.com/ProInfo/support/support/mainboard/4GB_Rev1/4GB_Rev1.pdf
