I tried to install Opensuse 11.2 in my workstations.
It’s OK for our first one which is 16 GM memory
But it only recongnized 24 GB for our second machine which has 32 GB memory
However the windows 7 can recongnize the full 32 GB memory
So is there any way to support more than 24 GB?
Which openSUSE, 32-bit or 64-bit?
Hi
What is the output from the command;
uname -r
Also what CPU are you using (model number)

32bit openSUSE will suport up to 64Gb (with PAE).
64bit openSUSE will support up to 256Tb .
How do you determine how much memory your machine recognizes?

32bit openSUSE will suport up to 64Gb (with PAE).
Additional info: pae is offered by the “Desktop-Kernel”.

64 bit 。。。。。。。。。。。。
I think the 64 bit version doesn’t need PAE. Am I right?
In fact I only installed the default components.
I don’t know why there is only 24GB showed…

I am using two Xeon 5520 CPUs

That is correct. Maybe some BIOS-setting prevents the whole RAM being addressed?
Is there any problems with my installation or is the opensuse’s bug?
Hi
OK, just checking it wasn’t an i7 
Can you check your BIOS settings
are ok for memory? Also post the output from;
dmesg | grep BIOS

Really. You mean Desktop has PAE too.?
I didn’t realize.

There is no PAE for 64bit processors.

Could you post the output of:
dmidecode -t 6

“Too” as what kernel? Because the default-kernel does not.
You said
Additional info: pae is offered by the “Desktop-Kernel”.
Sorry, I don’t get your point at all, caf4926.
• bcboycn was asking what size of memory is supported by SuSE
• Per Jessen explains that the 32bit kernels with pae will support up to 64GB of RAM while 64bit kernels support up to 256TB
• Since there are several 32bit kernels for openSUSE (namely the “desktop” and the “default”), I added the information that pae is provided by the desktop kernel (while the default kernel does not include pae)
• Then you state you didn’t know the desktop kernel has pae too
That’s why I am asking what you mean by “too”? Because the desktop kernel is the only kernel by the openSUSE-team offering pae¹.
¹ I am leaving out “unofficial” SuSE-kernels such as jengelhs ‘rtpae’ kernel etc.
On a 32 bit install with say 6GB RAM
Will kernel-desktop address the memory
Like the kernel-pae
Does that make sense, or am I a numpty (feel free to confirm in the +) 
Whoops, I didn’t know openSUSE was actually offering a literal ‘kernel-pae’, that’s why the confusion happened - sorry about that, caf!
Yes, the desktop-kernel features pae out of the box:
kalle@hoppers:~> uname -r
2.6.31.12-0.2-desktop
kalle@hoppers:~> cat /proc/meminfo
MemTotal: 4099940 kB
...]
A 32-bit kernel would use only about 3.2 to 3.6GB of my 4GB RAM (I can see that whenever using a 32bit live-system such as Knoppix).
No worries. Enjoy
