    Question How to best overclock the Intel Core i7-3930K?

    I have a Core i7-2700K 3.5 Ghz (seen by Windows as an 8 core CPU) and a Noctua D14-2011 air cooler. I'm looking to buy a new motherboard however on my current Asus P8Z77-V Pro motherboard to overclock to 4.4 Ghz I did this:

    • Put the AI Overlcock Tuner on XMP
    • I left the Memory Frequency on the default of 100 as increasing it caused instability. I could only get 0.046 Mhz extra in my overclock safely so I didn't bother.
    • I set "CPU Multiplier" to 44. I left Turbo mode on as disabling it made things much slower.
    • I changed the CPU voltage from offset to manual and set it to 1.220
    • I have the following RAM: 8GB (2x4GB) Corsair DDR3 Vengeance Jet Black Low Profile, PC3-12800 (1600), Non-ECC, CAS 9-9-9-24, XMP, 1.5V


    I got that RAM as I was told overclocking works best with 1600 RAM.

    Overclocking the Core i7-3930K

    Would I be able to get from 3.2Ghz to 4.4Ghz with my air cooler doing the same as the above or should I use different settings and buy different RAM?

    I read this on another website:

    "Using a CPU voltage of 1.4V, a CPU multiplier of 38x, a Base Clock of 123.75MHz, a CPU strap of 125MHz and a memory speed of 1.98GHz, we could also run the i7-3930K stably at 4.7GHz."


    Is the base clock the RAM memory frequency? What's a CPU strap of 125Mhz?
    Is the memory speed the CPU multiplier?

    Also I noticed people mention on another site that they disable Turbo Mode but that doesn't make sense as on the Asus P8Z77-V Pro that gives a much slower speed.
