I know that is a little diference between 7.8gb to 8gb, but still a diference, why Ubuntu dont recognizes all of my RAM? I had the same case with my 32 bit Pc, 3gb RAM and Ubuntu only recognized 2.98gb, again, it is a little direfence but I wish to know why that happens.

There's nothing wrong, it all comes down to this: IEC Units-7.8GiB, SI Units-8GB. – Uri Herrera Jan 1 at 20:14
What application in Ubuntu shows this? Please provide the output of free -m from the terminal to have a non-ambiguous representation. – gertvdijk Jan 1 at 20:31

It could be either that the system is using IEC Units instead of SI units, or that your Graphics card reserves space for its personal use.

For example I have 2 GB Ram installed, but only 1.7GB is usable because 256MB are dedicated to my Graphics Card.

0.2MB is not RAM taken for an IGP.. they usually use 256MB or more. – Uri Herrera Jan 1 at 20:25
I just noted both situations. I know it's probably the first. – Dialogos Jan 1 at 20:29
well, I just wanted to know if this was normal, and I see that it is, thank you for the comments. – David Jan 1 at 20:43
