    Just noticed when I start my PC that my motherboard reads my RAM as 6134MB? Should this not read 6144MB? I do not have any shared memory within the system? What is wrong here, is it my mistake or should it not read 6144MB? And if I am wrong what is the other memory being used for?

    Thanks.

    Its 6144, but just because it equals that doesn't mean the motherboard will read all of it. There could be a stuck sensor or something else causing an improper reading. But uh, if its only 10MB.. I wouldn't worry about it at all.

    Simple math dude ... 6 * 1024 = 6144.

    Manufacturers may not provide the full 6144 to the number, since they usually round stuff off. This is like buying hard drives. It lists 500GB, but you tend to never get that much.

    Well I will run my system through Memtest86+ and see if I get any errors. System seems stable though, runs through Prime95 6 hour test fine.

    Motherboards used to do long tests on RAM as they started, and looked up the amount of memory twice.

    Now they do a quick estimate and move on, that might be why it's only showing as a little less.

    Either way, it doesn't matter.

    honestly that is NOT a good comparison..the reason it lists 500gbs is because manufacturers read 1000mb as 1gb and windows does 1024mb as 1gb..thats why u lose space.

    as far as memory missing idk..but mine in task manager reads 6135 but in cpuz it reads 6144..which are you looking at?

    Well i know build in sound/sound cards and Ethernet ports take up ram so guess that could be it.

    Yeah, but they wouldn't use 10mb surely? Anyway, what does Windows read the RAM as, or any of the programs mentioned above?

    Disk comparison is faulty even more, as after formatting partition you get less (like 305GB out of 320GB disk)
