Hi, this is my configuration

Core i5 750
Gigabyte P55-UD3
G.Skill F3-10666CL7D-4GBRH
Samsung Spinpoint F3 1TB
Corsair 750W

the rest isn't important i presume.

I'm currently running F3 version bios, and would like to upgrade to f4, but I would like to know what the recommended bios settings are (I presume they are not saved after bios flash)

Thank you for your help
