Chris Miller :
I have recently set my cpu to 4.20ghz in the bios, the weird thing is it shows that its running @ 3.50ghz and only uses 4.20ghz under load, how do i get it so that it runs constantly at 4.20ghz instead of 3.50ghz at startup.
What is showing it is only running at 3.5ghz?
Many programs only report the stock speed of the CPU you have to use something like CPU-Z to monitor the actual core speed.
Additionally your 3770K overclocked speed is dependent on the Intel features you leave enabled to accomplish your overclock, click on my CPU-Z validation.
