Default Sabertooth X79 O/C settings

I'm a complete newbie to O/C. I have the ASUS Sabertooth X79 with Intel i7 3930K chip.
Before I started to O/C, I check stock speed. Imagine my surprise when I found this stock 3.2 GHz chip was shown in CPU-Z as having a "Core Speed" = 1200 MHz; Multiplier = 12.0;
Bus speed = 1000 MHz; QPI Lind = 3200 MHz.
First question, how to I recover from this severe underclock and achieve the stock speed of the chip?
Second question, what do I increase in the AI Tweaker to achieve an O/C?
I could not find any "Multiplier" setting.
Thanks in advance to the experts.

To recover from your severe underclock, put your chip under load, it will ramp up to the correct speed.

My preferred way to overclock is with Intel's extreme tuning utility, download it from Intel's site, it's pretty straightforward.

Yuriman, thank you for the response. I realize that when I put the chip under load, it will go to the correct speed. However, I want to change whatever setting in the BIOS (or Windows 7) that is causing the underclock. I want to have the system run at stock speed before I start the O/C.

Not sure why you want to but it does look like it's possible to do what you want to do with your motherboard.

In UEFI advanced > CPU Configuration > CPU Power Management Configuration > CPU ratio looks to change the minimum clockspeed at least on the youtube video I found.

Guess you'd have to try it and see.

Ken, thanks for the tip. I will try it tomorrow. Since my system will be running O/C almost all the time (if I can figure out how to use the AI Tweaker to do an O/C), I don't see a reason to have it run severely underclocked ever.

Modern processors underclock when not in use to reduce power consumption and increase the life of the chip. As a side effect it also dumps less heat into your room.

My 3570k for example sits at 1600mhz while I browser the web or am away from my pc and don't need the extra speed, but when I open a game or unzip a file for example, it instantly ramps up to 4.7ghz, giving me the power when I need it and not wasting energy when I don't.
