I have a laptop with this cpu that I can overclock to 3.0 ghz I get the extra 0.5 ghz from increasing the multiplier from 9x to 11.5 and increasing the turbo core boost to max but Thats not all I can overclock it more with my laptop motherboard by boosting the fsb witch will get me to 3.6 to 3.9 ghz which is amazing for a laptop: 1 benchmarking battlefield 4 on low settings with 4 gigs go ram :( but cpu overclocked to 3.0 ghz ; ) it's amazingly gets 11.2 to 31.2 frames per second which means still playable but with more ram: 2 benchmarking MINECRAFT with highest settings and get a real smooth 67.1 to 123.3 frames per second but it's overclocked to 3.0 ghz, now let's test 5x by 5x TNT raped fire TNT cannon that shoots about 11to 22 or more TNT per second for 4 min and well my frames dropped to 31.3 to 62.1 frames per second no lag. works beautifully . Btw if you want to know the overclocking tools I used is 1: AMD overdrive 2: setfsb ,, sorry I doint have the links so yea that you will have to do you, and I nearly forgot the temps , the temps will be on the edge to unhealthy temps when overclocked to 3.0 ghz and wile playing battefield 4 on low settings also if your realy want more power out of the cpu setting the fsb is a way of adding more power but risking the life of your computer which I'm happy enough for good frame rates for battlefield 4 and minecraft have givin me I suggest not to set fsb because a dead computer is useless.
