i just overclocked my AMD phenom II x2 555 to a x4 B55. everything was smooth i had all four cores running at 3.7 mhz. i am using Asus Overclocking program. and i pressed the Turbo V button to see what it does and it shut my PC off and when it restarted the cores were at 3.4 mhz. is there a problem or is it a good thing it's at 3.4 and not 3.7. at 3.7 there was more warm air coming out but now it's cool. i tried it once more and all cores were still at 3.4 except one which was at 4304 mhz. my system is stable and i have not gotten any blue screens. should i try to increase any further?
