Have you test the 64bit install image ?
We told you several days ago that your cpu (AMD FX[tm]-8150 Eight-Core 
Processor) is a 64 bit cpu.

You'd better reinstall a 64bit system.
Using a 32 bit system nowadays is not a good choice.

Be patient and careful.
Install and config a new gentoo may very painful at start, but when you 
did it, you will happy for a long time.

i686 is a 32-bit kernel. Where it says "i686" it should instead say
"x86_64". For example, on my Gentoo server:

Linux legend 5.4.80-gentoo-r1-x86_64 #1 SMP Wed Dec 2 10:51:23 PST 2020
x86_64 Intel(R) Core(TM) i5 CPU 650 @ 3.20GHz GenuineIntel GNU/Linux

I don't know. You've done something wrong.

Do you have a /proc/config.gz file? zcat it and look for settings of the
running kernel that indicate limiting memory or something.

Sorry. I'm not able to help you much more at this distance.

You show all 16GB but as others have stated you are likely running the
wrong kernel.

Or lshw and look for the DIMM modules themselves


Or is this a 32-bit system WITHOUT extended memory support?

I don't properly understand it, but with a 32-bit system the kernel uses 
1GB of memory and user-space uses the other 3GB. Extended memory support 
means each process can have its own 3GB space which enables you to use 
all available memory, but without it I think the entire system is stuck 
in the first 4GB.

Wol

Are you perhaps booting a 32-bit kernel? A 32 bit kernel is not going to
see all 16GB of RAM, only what fits in its 32-bit address space. You need a
64-bit kernel (or a 32-bit kernel with Physical Address Extensions enabled)
to be able to see all the RAM.

I run Memtest86 on my old box and it completed 1pass without any errors.
Memtest86 reports 16G memory

When I boot Gentoo it shows only 3282Mb
free -m
  totalusedfree  shared  buff/cache

Is it a motherboard? How to test it?
