hey i have 2 8gb sticks running at 1600mhz, so going into system info it says i can only use 7.98gb out of 16gb , ive tried everything, driver updates, putting the sticks in different slots, doing the msconfig and changing max ram but still nothing after restarting many times. ive only noticed this problem after going into BIOS and also seeing that its running in single-channel mod for 2 sticks???? PLEASE HELP!!!!
