bought 3 4670k's cant Overclock past 4.3GHZ
Building a side pc and Im having problems overclocking a 4670k. I was planning on delidding, but the first processor I bought was only stable at 4.3GHZ at 1.26V steady under load. I bought another 4670k thinking I had lost the silicon lottery, and it only did 4.1GHZ at 1.25V, which is worse than I have ever heard of. I sold that cpu and bought another yet and this one also only hits 4.1GHZ at 1.26V!
I assume something is wrong here, from what I see the average 4670k hits 4.5ghz, the very worst 4.3, and the best 4.8, so the odds I buy 3 and they are all literally worse than the worse is very very low.
I'm here to see if any of you have suggestions? maybe there is a setting I need to change or something that might help the overclocks?
