Turbo Boost causing random freezes on P55-GD80

[CNauta]

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, and Intel problem, and/or a Windows 7 problem.

Any thoughts/suggestions would be appreciated.

Any thoughts?

No one has any thoughts/suggestions?

Any suggestions on where else I could look/search for answers?

Performance mode probably means having higher voltages or higher "optimized" settings to run the system. Fail safe mode already spelt out its intentions to keep the system from failing.

For details, you can contact MSI for more information.

As I stated in my first post, I carefully went through all of the BIOS settings and the only thing I could find different between 'default' and 'optimized' is the setting for 'Intel Turbo Boost'.

I will post a question on the BIOS board about any other differences, but until then my original question remains...

...does anyone know of any problems (and hopefully FIXES) with the P55-GD80 and Intel Turbo Boost?

Have you tried disable the phase controls in the Green Power section?  When I do,the weird reboot and lockup on my system stop.

If your are running the memory at 1600 MHz (XMP) you must disable Turbo Boost and/or make sure the CPU is running at a proper frequency by lowering the CPU multiplier.

To have the memory running at 1600 MHz the base frequency is raised from 133 to 160 and thereby overclocking the hole system!

As I also had problems with instability like this, I intend to make a topic about this, because XMP is very confusing.

On my computer, I have to have the auto phase controls in the Green Power section disabled. 
When that is done, I can turn on both XMP at 1600MHz and Turbo Boost.  The computer will run stable.

If I didn't disable the auto phase controls in the Green Power section, the computer will reboot and lockup even with both XMP and Turbo Boost disabled and the base frequency at 133MHz.
