Asus Vivobook Asus VivoBook D509DA-EJ098 RAM NOT DETECTED CORRECTLY

Hi,

I've been playing around with arch in VirtualBox a few months now, and I have just decided to buy a new laptop and go ahead to install it.
I have already installed a tiling WM, sound, graphics & touchpad drivers... etc, but the computer has 8 GB ram and the system does only detect 6.

I've been time searching for a solution but I just can't get it right, can someone help me?

Thanks.

Okey, sorry.

When I check the total memory this is what I get:

# cat /proc/meminfo | grep MemTotal
MemTotal:        6099892 kB

But when I check the RAM sizes this is what I get:

# sudo dmidecode -t memory | grep Size
    Size: 4096 MB
    Size: 4096 MB

This is my dmesg: https://pastebin.com/XnEypYEW

OT but:

# cat /proc/meminfo | grep MemTotal
MemTotal:        6099892 kB

Useless use of cat:

grep MemTotal /proc/meminfo

And please use code tags rather than quote tags when posting terminal output, as I have done above.

This is my dmesg

[    4.005506] amdgpu 0000:03:00.0: VRAM: 2048M 0x000000F400000000 - 0x000000F47FFFFFFF (2048M used)

^ Your Vega iGPU is grabbing 2GiB. Try using the vramlimit option for the amdgpu module to change that: https://wiki.archlinux.org/index.php/Ke … le_options

Reference: https://dri.freedesktop.org/docs/drm/gpu/amdgpu.html

And it looks like you haven't installed the linux-firmware package, the graphics chip will need that for full performance.

All right, that is enough. I have so many things to learn.

Thanks for your help
