I just got my motherboard and installed the Gigabyte drivers and have BIOS version FB or whatever and. I noticed in core temp that my cpu is rarely ever at the stock 3.4GHz frequency it should be at all the time. I have the UEFI duel bios that's kinda 'cutesy' i think is what its called where you can use your mouse to control it.

my questions:

1) regarding throttling...what settings and things do I need to disable in my bios? I know about cool n quiet, but I can't find it in the BIOS. People are mentioning in other threads to turn off some other settings that aren't needed and can hinder overclocking, but I don't know where these are in my bios

2) my ram timings got recognized in the bios as 1333 MHz, even though I just bought corsair vengeance pro series 1600 Mhz , 9-9-9-24, 1.5V.

how do I fix this problem and get the ram to be recognized at stock timings as advertised?

3)windows 7 home premium which I have a CD of retail copy I bought. Windows won;t activate .... such a pain in the you know what...

The statement "the stock 3.4GHz frequency it should be at all the time" is wrong. If you want to disable Cool n Quiet and C1E in the BIOS you can. C1E is a power management state that allows the processor to reduce power beyond just the cores. With C1E, the processor power can be reduced by lowering the memory controller clock speed. You can also set the Power Management Scheme in Windows.

To get the ram to be recognized at stock timings as advertised turn on XMP profiles in the BIOS.

Gotcha. Thanks for the reply !

On this board I can't find cool and quiet or c1e ! :( 

Simply turning on xmp gets the ram to 1600? Or is there more I have to do

with regards to the cpu throttling; in the bios find CORE PERFORMANCE BOOST and turn it off. I cuases the cpu frequency to bounce around all the time. As for the memory, turn on XMP and it will automatically drop the memory's stock timings in for you.
