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.
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.
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.
