RAM not recognized on hard boot

[ascii11011]

Hi. I have an ASUS Chromebox running Ubuntu 16.04 LTS, standalone.

I upgraded the RAM from 2 to 8GB. Crucial 8GB Kit (4GBx2) DDR3/DDR3L 1600 MT/s (PC3-12800) SODIMM 1.35V/1.5V 204-Pin Memory for Mac - CT2K4G3S160BM

Upon initial boot, ie, pushing the on button, free -m shows only 2GB.

total used free shared buff/cache available
Mem: 1988 833 640 158 513 816
Swap: 2036 888 1148


However, sudo lshw -class memory
shows all 8GB.

Any ideas? Thanks

Currently does it show the 8gb total? What does ubuntu state the system has?

Nothing has changed. However, further experiments showed that when the ram is first installed, either 2 cards or one at a time, they show the correct RAM upon first boot.
Thereafter, it reverts to the screwed up behavior.

Sounds like a bios issue..

What is the model of your chronebox?

Thinking either the ram is faulty or the motherboard has an issue. Does the old ram get recognized the 2GB? If the answer is yes request a replacement for the ram.

It's the M004U. I've switched out the RAM --- no change.

Haven't tested the original 2gb memory. I'll try it tomorrow and post results.

Thanks for trying to help
