RAM memory is reserved by the system. Why can't I use all the memory, but only a part of it?

Worth Windows 7 Maximum 32 bit ... Only 6 RAM and only 2.5 GB is used. Could it depend on OS architecture?

32bit Win addresses 3 GB.
With special option up to 4, but part it still goes to video memory, so about 3.3-3.5 will still be available.

Yes, it's 100 percent architecture dependent - 32-bit systems can't address all 6 gigabytes.

Yes, for x32 the maximum usable RAM is 4 GB. Minus non-relocatable device address ranges. Usually it turns out ~ 3.7 GB. You have much less - it is worth looking for the reason.
