2GB Pine 64 only has 1GB

what about running a memory tester just to see what happens ?

I installed Armbian and this is what I get one login

Welcome to ARMBIAN 5.38 stable Ubuntu 16.04.3 LTS 3.10.107-pine64   
System load:   0.24 0.36 0.22  Up time:       12 min Local users:   2

Then I tried the memtester and get the following result

You can see the picture of the hardware, its a 2GB model but showing 1GB with all the OS i tried.
I have opened a claim to the seller now as a hardware fault.
