ok so i set every settings one at a time before i changing the multipliers to 45. so far so good.had to restart for some settings but they did not all work. some did however. seems stable so far. 10m and max temps 67c. seems odd was maxing at 72c before. anywhoo my system is 4.5ghz at 1.280v, is this good? i tried 1.275 and was stable for 4hr stress test however my pc crashed playing mafia 3 after about 6hrs and then immediately after running it again. bumped to 1.280 and was good. ive read others are getting 4.5ghz at 1.225-1.25v and cooler temps. mine seem a bit high. im new to OCing, never cared for it before, also using intel extreme tuning utility. easiest way ive found
