    Size of installed RAM vs what KInfocenter reports

    Okay. Why, when I have 8 GB of RAM installed, does KInfocenter report 7.60 GB?

    Your brain is thinking in gigabytes, while KDE is thinking gibibytes.

      You can change this at System Settings -> Locale -> Country/Region & Language -> Other.

          Oh -- don't ever go around saying "gibibytes" at a geek party or whatever. I promise you'll get the snot kicked out of you

            Now THAT bit of advice (party protocol) is helpful
            Actually, I have never liked the "bi" business. It even sounds a little, shall we say, light off the tongue ...

                Truly, they are bits that swing both ways! BWAHAHAHAHA

                    Well, that just simply sends gi-bi-bytes up my spine ... I just love those powers of two, don't you?

                      Three is better.

                        While this surely explains why KInfocenter says 8,161,075,00 = 7.6 GiB, it does not answer the question as to why it does not show as 8 GiB, which is very likely to be the amount of RAM in Snowhog's computer.
                        I would guess that the computer has on-board graphics, and some of the RAM is dedicated to that.

                          Just waking up, too early here to poke around in my empty component packaging/manuals, but I suspect you have to read the specs that came with the memory modules--ditto for things like flash drives--to see how the manufacturer measures and advertises the memory specification, powers of 2, or powers of 10. Seems I recall this is an issue for flash drives. (Then, you still gotta minus the overhead-system or reserve memory used by the manufacturer.)

                            For example, Crucial memory:

                            "Gigabyte An amount of memory equal to 1024 megabytes (1,073,741,824 bytes) of information. Abbreviated GB. Other common DRAM units of measurement are kilobytes, megabytes, gigabytes, and terabytes. Because bytes contain 8 bits of information, gigabytes are naturally larger than gigabits."

                            http://www.crucial.com/usa/en/support-glossary

                            - - - - -

                            Powers of 2 for Crucial, then. I suspect that's usually the case; the term gigabyte is misused--as an industry norm. But, as mentioned above, you must still check to see how much of that theoretical capacity is reported in your utility.

                              For DRAM the term gigabyte still commonly refers to 2^30. But that's not the point, for addressing reasons it does not make sense to make RAM in anything other than powers of 2; in my admittedly limited (but long) experience I've never heard of RAM being made otherwise. The OP's computer's RAM is very unlikely to be 7.6 GiB.
