I have 16gb of ram when i did a check the system says im only using 2.6gb . I'm obviously missing something simple and not being as clued as i would like to be on computers I'm hoping you kind people can help.
The memory is from novatech with their own label so a lack of cl setting
my system is:-
AMD FX-8 8320 Processor - 16GB 1600Mhz DDR3 Memory (4x4GB) - AMD 970A motherboard
1100w psu
60gb ssd
3tb storage drives
g/card MSI R7 260X OC 2GB

other reason for asking is i keep getting low memory messages when playing world of warcraft (sorry if that a swear word :))
hoping you can help
many thanks in advance
