How to get access to all 4G of RAM?

[patkoscsaba]

I just upgraded my system to 4G RAM and I use MDV 2011 64bits with kernel nrj-desktop 304. However it reports only 3.2 GB RAM. My computer and the BIOS can tells me correctly that there are in fact 4GB.

Any ideas on how to make my system see all the 4G of RAM???

PS: I also installed a server-rsbac kernel, also version 304, but it can not boot. It tries to connect to some rsbac socket on boot and it fails and it indefinitely retries.

A 64bit arch 2011 should use all memory, I can't understand
The your seems a problem could happen only in a 32bit OS

My PC:
I have 4G ram, and 256M is for video card shared memory
and as you can see (4096M - 256M), i have 3.8 total ram!

With 2010.2 64bit, you used all 4 giga ram?

Just now, workin on kernel 3.0.7, if you can wait, you could try this newest for tomorrow

Hi Nicco, I've put all the outputs from dmidecode, proc/meminfo, hwinfo and free on this comment at mandrivausers.ro: http://www.mandrivausers.ro/comment/25527#comment-25527

Additionally I checked:
- I have NO options for PAE in BIOS
- I have NO options for any memory parameters in BIOS
- the bios DOES correctly show 2x2GB and a total of 4GB RAM

uname -a:
Linux localhost.localdomain 3.0.4-desktop-nrj.69mib #1 SMP PREEMPT Thu Sep 1 23:15:03 VLAST 2011 x86_64 x86_64 x86_64 GNU/Linux

Also other users on mandrivausers.ro seems to not have my problem.
I checked HP support (this is a HP DX2300 micorotower) and all official documentation says 4G supported for my computer.

[NicCo]

then wait for kernel 3.0.7, it's upcoming soon

[NicCo]

kernel nrj-desktop 307 for 2011.0: ready and available

Kernel 3.0.7 + -NRJ and -NRJ-PAE for 2010.1, 2010.2, 2011.0
http://mib.pianetalinux.org/mib/forum/v ... =38&t=3074


bye, NicCo

[patkoscsaba]

Thanks. I installed it, same problem. I think I will make some test with the original kernel version (2.6 desktop and server) to further test it, but only tomorrow.

Congrats for the new kernel release.

[NicCo]

You could try to specify the exact memory amount that you own, in kernel line,
i don't remember the command and the syntax, but you can search in the web


bye, NicCo

[patkoscsaba]

So, I found out that I can use the "mem=4G" kernel option at boot to specify the exact amount of RAM I have. However, this has no effect. The system still reports the same 3.25G available.

Here is a grep for "mem" on my logs from the last boot. Can anyone see any problems here?
