Yes, i know. Thats why i wonder.
I use to have 3 GB DDR3 in triple channel ( 3 x 1 GB ) and i added soon 2 x 2 GB DDR3
Maybe the order they are in the RAM slots on the mobo is not okay?
Could that be the reason ?
My mobo is Gigabyte GA EX58 UD5
I have 3 x 1 GB DDR3 in 2 / 4 /6 slots and the other 2 x 2 gb are in slots 5 and 3

I'm not positive, but I think the sticks may all need to be the same size. I could be wrong though.

Another x58 memory problem. Lots to try here,

Asus X58 + 6/12GB memory overclocking - detecting less memory than installed - i4memory.com - different look at memory

and hope you don't end up like the two here that never didn't manage to fix it,

Should i try to change the memory slots ?
Or maybe an BIOS update ? I have now the BIOS version F9 and, as you can see in the image, BIOS vers. F10 and F12 have ENHANCED MEMORY COMPATIBILITY.
What do you think ?
Thanks a million.

While matching sticks is not essential it is highly recommended.

Some ram just acts up when pared with non identical moduals.

Also its not uncommon for a issues to occure if all 4 ram slots are used. But its sometimes only mobo specific.

Less than 4.0 GB RAM usable?
It's funny, because ALL of my RAM was usable some time ago. (I have no idea how long ago this was, but it was on the same OS) I am using Windows 7 Professional 32-bit. I know about the whole 32-bit issue where some say you can't use much more than 3GB. Well, I WAS. I wouldn't be writing this...
