[GTALUG] Not recognizing added RAM

[Evan Leibovitch]

Hi all,

I thought I would know how to handle this but it turns out that I don't.

I just added two new sticks of RAM to a system but it's not recognized by
the BIOS or OS.


# inxi -m
Memory:    RAM: total: 7.74 GiB used: 2.93 GiB (37.9%)
           Array-1: capacity: 16 GiB note: est. slots: 4 EC: None
           Device-1: DIMM_A1 size: 4 GiB speed: 800 MT/s
           Device-2: DIMM_A2 size: 4 GiB speed: 800 MT/s
           Device-3: DIMM_B1 size: 4 GiB speed: 800 MT/s
           Device-4: DIMM_B2 size: 4 GiB speed: 800 MT/s

So Inxi sees all 16GB (as does memtest) and yet in the first line it shows
RAM total at 8. dmidecode output is below

Motherboard is an Asus F2A85-M. BIOS has been reset to defaults but not
updated since the mobo was purchased.
OS is current Manjaro KDE.

The website specs say it can take 64GB.
Is updating the BIOS necessary or are there other solutions?

All help is greatly appreciated.

- Evan
