Hello,
I have Windows 7 x64 Pro and it was freezing occasionally. I discovered in BIOS that the multiplier is set to x34, but on initialization it reads x37, so it works on 3.7GHz. I tried to reset the BIOS to defaults, even with the jumper on the MB, but still the same. I now use RealTemp to disable the turbo so it can work at 3.4GHz as before and it doesn't freeze anymore. Can someone tell me what is the problem? I don't think that by using RealTemp is the solution.
Thank you in advance.

The P67 motherboard was released for Sandy Bridge. While it should be compatible with Ivy Bridge, I would expect a high probability that a BIOS update is available from Gigabyte that may iron out some / all of those issues. What BIOS revision are you at now? F7 is available, but F6 was the start for full Ivy Bridge support (I am assuming you have a Rev 1.0 board).

Hello sadams04, Thank you for your reply. The MB is Ivy Bridge compatible, Rev 2.0 and the BIOS version is FE. I downloaded the update and still the same.
I noticed some strange things in Windows 7. I have installed two instances of Windows 7. In the first Windows, when analyzed with CPU-Z, under the 'clocks' section the multiplier reads x37.0(works perfectly without RealTemp initialized to disable the turbo, but it makes the fan to cool it with 2500RPM or more which is annoying and the CPU temp reaches more than 65C), and in the second Windows it reads x16.0-x39.0 which means it varies the multiplying depending on the CPU usage.
I have tried to change some settings in the BIOS and found this:
Internal CPU PLL Overvoltage set to 'Enabled'; default is 'Auto'
Intel(R) Turbo Boost Tech set to 'Auto'; default is 'Auto'
Any other settings freezes my pc in either Windows, only the above mentioned function well and as I described.
You may download the manual and see for yourself if you are interested and go on pages 34-35
