CPU acting weird
CPU acting weird
What happens when you run Cinebench or another stress test/benchmark? Does same thing occur there? Only reason I can think of Turbo not staying at max is that load is changing too much, or that you are having temp issues and CPU is throttling because of those. As its locked CPU, you can't do much to fix those things. But to get better temps, if those are issue, is to set manual or adaptive voltage. Thats setting which should be available for you.
What driver would that be? Mobo is irrelevant for GPU drivers, and chipset ones support all supported Windows versions (7,8,.1 and 10).
