Problem with Intel Turbo Boost

I just built this computer last week:
  • MSI P55-GD80 mobo
  • 8 GB Corsair Dominator RAM (240-Pin DDR3 SDRAM DDR3 1600 (PC3 12800))
  • Intel i5-750 CPU
  • Cooler Master Hyper 212 Plus
  • Corsair HX750 PSU
  • Radeon 5850
  • Windows 7 64 bit

I was getting random freezes in Windows (and not just Windows, the whole computer would freeze requiring a re-boot). I could discern no pattern in the freezes. They came at different times and length of operation. They came with different programs running.

When the system rebooted there was never any Windows error message.

I checked CPU temperature and it was running at a cool 28 - 30 degrees C.
I ran Memtest and everything passed.

On a lark (and because it had fixed another, different problem I had had earlier), I went into the BIOS and changed it from "Performance" defaults to "Fail Safe" defaults.

Lo and behold it stopped freezing up!

When I went back to look at what the differences were between the two defaults, the only thing I found was "Intel Turbo Boost". In "Fail Safe" it's disabled and in "Performance" it's enabled.

Obviously I can run it disabled (and maybe I don't even NEED to run it), but I was wondering if there was anything I can do to "fix" this problem.

And to be honest, I don't know if it's an MSI problem, an Intel problem, and/or a Windows 7 problem.

Any thoughts/suggestions would be appreciated.
 
If I recall, intel turbo boost OCs the processor slightly if not using all the cores. So perhaps it's just unstable with that minor overclock? You could try giving it some voltage or maybe the PSU is having issues.
