I have Ubuntu 16.04.1 LTS and it only reads 3.6 GB of it. I tried to configure the graphics memory size in BIOS and made it the least value but it is not solved. Can anyone help me? Cause I'm doing a heavy process and I need my whole RAM.

  1. You most likely have only 3,90625GB of RAM, producers mark 4000MB as 4GB, but ubuntu iterprets it as 4000/1024 GB, which equals to mentioned value.
  2. If you have integrated GPU then some RAM is reserved for it, also system reserves a bit. Let's say that sums up to about 306MB, that's it, now you have 3.6GB left.

Keep in mind that in spite of comments, 32 bit Linux OS also support huge amount of RAM due to using PAE.
