Sorry .... posted in the wrong place before.
I have Gigabyte's Z87X-UD3H mobo with a F7 bios running an Intel cpu i5 4670 and it doesn't seem to carry the cpu settings I apply into Windows according to Cpuz and OCCT. I ask for 4.6 or 4.5 (with all the other appropriate settings) and I only see 4.2 or maybe 4.3 displaying in those apps UNLESS when I'm in Window7 enviroment I use Gigabyte's TweakLauncher and set core and uncore in it. Then I go back to Cpuz and my settings show up correctly. So I know my system is capable. I suppose I could just launch TweakLauncher each time but why won't the bios correctly set my input??? I erased, reset and loaded optimized settings numerous times but it doesn't make any difference. Maybe I should go back to bios version F5 ?? It is confusing .... any ideas I can try?
