Hi guys,
I have 8 GB DDR3 kingston ram
its bus is 1333
but when i installed the control center (program by msi)
i found that the windows is using only 667 MHz !
I want to work with the whole 1333 MHz
one other problem
ive never used my ram at its maximum power
i want to use the whole 8 GB of my ram
my computer remains slow when copying or doing any thing else and it doesn't use the ram !
please tell me what to do !?
