Before install of the chipset the cpu runs at 2.5ghz and 86% at full load. (its an i7 3520m). After chipset is installed, it goes to it's advertised 3.6ghz and runs at 100%. Ok, seems fine, then without warning: poof it's back to 2.5ghz and 86%. Rerunning the installer with -overall (command for reinstalling everything) it only sometimes works. It this a hard drive problem, an os problem, or what? PS: my laptop is dell latitude e5430. I have tried this on two different hard drives (because one has some - but slight errors) and the result is generally the same after installing the drivers from the manufacturer. I reinstalled the drivers on both hard drives. It worked, but it will probably just revert back. There are also some rare instances of it only going up to 1.8ghz
