Hello Guys,
if i playing Diablo 3 my fps drops down to 3 - 10 and its nearly unplayable. After some research, i saw that only 4 gb ram of my 8 gb are in use. I tried many things, uncheck maximal memory in msconfig, memtest, bios settings... but nothing changed. I have two Ram Slots and in both is the same RAM -> 4bg, 1600 MHZ, but dual channel mode is not activating automatically, like it should. After all, i have no ideas what i could do now. Here are some screens of my CPU-Z testing. Thanks for your help.
