[SOLVED]Full amount of Ram not detected

Greetings to the Forum!
I can see that the thread of gabe.benson is marked "solved". https://bbs.archlinux.org/viewtopic.php?id=126170. But my problem is quite similar and very weird so i decided to open the thread again. I am new in this forum.
I face the same problem, just like the person who opened the thread. My computer Ram is 8G. BIOS, live-cd's and other distributions detect it properly. I tried removing the ram sticks and puting them carefully back in place with no luck. I also tried reseting to defaults.

$uname -a
Linux lilwing 4.4.35-1-lts #1 SMP Sat Nov 26 17:36:32 CET 2016 i686 GNU/Linux

checking the ram on Arch :

$ free -m
              total        used        free      shared  buff/cache   available
Mem:           3285         626        2113          68         544        2415
Swap:             0           0           0

Checking with lshw :

$lshw | grep -A 8 bank 
        *-bank:0            
             description: DIMM DDR2 Synchronous 667 MHz (1,5 ns)
             product: PartNum0
             vendor: Manufacturer0
             physical id: 0
             serial: SerNum0
             slot: DIMM0
             size: 2GiB
             width: 64 bits

             physical id: 1
             serial: SerNum1
             slot: DIMM1

             width: 64 bits

        *-bank:2
             description: DIMM DDR2 Synchronous 667 MHz (1,5 ns)
             product: PartNum2
             vendor: Manufacturer2
             physical id: 2
             serial: SerNum2
             slot: DIMM2
             size: 2GiB
             width: 64 bits

        *-bank:3
             description: DIMM DDR2 Synchronous 667 MHz (1,5 ns)
             product: PartNum3
             vendor: Manufacturer3
             physical id: 3
             serial: SerNum3
             slot: DIMM3
             size: 2GiB
             width: 64 bits

I tried to give kernel parameter mem=8G on boot. the result is :

$ cat /proc/cmdline
BOOT_IMAGE=/boot/vmlinuz-linux-lts root=UUID=573c4ab8-ab66-4280-a215-b11fb7403665 rw mem=8G

I done it editing /etc/default/grub and after that :

sudo grub-mkconfig -o /boot/grub/grub.cfg

weird...the amount of ram is stil not real. Biggest problem for me is that i cannot assign more ram on virtual mashines. The primary desktop experience is not really bothering me.
My motherboard, old, not really ancient, perhaps king Henry's age, is an ASUS M3N78-VM. It's last update in 2010 allowed me to use AMD 1055T prc. Couple years ago Arch was running with no problems at all. The installation this week brings on this matter. The most exotic on the MB setup i would consider mentioning is that on PCIe SATA adaptor i connect a Kingston SSD with the root partition of Arch.
Is this a bug? Do you have any suggestions?

You're running a 32-bit OS.

Re: [SOLVED]Full amount of Ram not detected

That's what I thought, and why I asked for "uname -a" -- glad you got it sorted. Please remember to mark your thread [SOLVED] (edit the title of your first post and prepend [SOLVED] to the title.)


How to post. A sincere effort to use modest and proper language and grammar is a sign of respect toward the community.
