I'm having some weird trouble with my i5 4670K. A few weeks ago I got some frame rate issues (which were caused by my really bad placement of the RAM its solved now) and I thought its my CPU's overclock messing with me. So I went to BIOS and defaulted everything, at the end everything worked out, but now I'd like to get my OC back. I got a great stable 4.2gHz at the default Voltages, but now my CPU-Z is showing my CPU only going to 1.7gHz (multiplier is at 17) and the voltages never rise above 0.816V so I thought its the program messing with me, I checked with AI-Suite III (which is really terrible, but it works) and it's giving me the same numbers. ATM my multipliers are at 8-38 but it is still stuck at 0.816V an 1.7gHz. PS, it isn't fixed at 1.7gHz it just is the max for some reason, thought you professionals could help me. Sorry about the long text.
