Hello, I am new to overclocking and I just built my new rig. The case is the Thermaltake Level 10 GT LCS and I installed the liquid cooling on it.

I want to take advantage of that and overclock
my CPU to 4.5 ghz, but I have no idea how

Can anyone help please?

The cpu is the intel i7 3930k

Hi there. Got allmost the same system. P9X79 Deluxe with a i7 3930K.

Thats a easy one:

CPU multiplier @ 45
CPU bus speed @ 100 Mhz
CPU voltage @ auto

System 24/7 stable no problem. Dont know what memory you are using.

Further with some tweaking with the voltages you can reach 4.9 Ghz Stable ( with temps @ ~ 58 degrees full stressed ( Corsair 100I )

Give me a shout if I need to show you were you can find the settings in your BIOS.

Please don't advice people to use auto voltage..... :(

Normally indeed you dont use the auto voltage but tested a couple of these mainboards with the 3930K's here and they do fine at 4.5 Ghz at auto voltage ( will run arround 1.32 ~ 1.35 volt ) ;) . Offcourse if you go higher you need to give the CPU a bit more juice .

Auto voltage is notorious for giving far more voltage than is actually needed, and in some cases giving a dangerous amount of voltage.
Anyway it's always best to check for the lowest voltage value that is still sufficient for a stable overclock because you'll get the lowest possible temps and power draw for your overclock and you'll CPU will last longer compared to auto voltage.

Well, it will not raise the voltage - not anymore at least. At stock speed (3.2 plus 3.8 turbo) it vill stop att 1.288V. If you change the multiplier to 42 (4.2 GHz@100 MHz BCLK) it still maintains 1.288 voltage even at "auto" voltage settings.

Later C2 steppings are perfectly stable at this voltage and up to 4.2 GHz. Temperature readings should be in the 30-35 (celsius) area while idle and 60-65 at full load. CPU package drawing about 60W of power (8-9W at idle and speedstepping enabled (C1/C3/C6/C7) plus a "Balanced" power scheme if you're running Windows).
