I have an Fx 8320. I've downloaded amd overdrive and it has the option to change the turbo core settings. I've increased the turbo core settings from 3.7ghz to 4 ghz and it is set to 4 cores. However, when I start playing games, it shows that all cores are raised to the 4ghz I set it at, not just 4. Is it supposed to do this? Also, why are there 2 boost levels options in amd overdrive. It seems that only changing boost level 1 will affect the turbo speeds.
