    How to Overclock ASUS RAMPAGE III Extreme BIOS GUIDE

    The ASUS Rampage III Extreme is an Overclockers dream. This board begs to ask how well can you overclock. At the hart of the Rampage III Gene is its the X58 chip set capable of Quad SLI, and Quadfire X the 1366 socket board is capable of Trippe Channel DDR3 and up 24GB of memory capacity


    System Specifications



    Defaults
    (22.22c Ambient Air Temperature)
    Core Voltage: 1.144V
    Temperature: 27c
    Core Speed: 3.33GHz
    Uncore Speed: 2670MHz
    Base Clock Speed: 133MHz
    Quick Path Interconnect Speed: 3200MHz
    System Memory: 3x Corsair Dominator GTX 4 2533MHz 2GB
    Voltage: 1.5V
    Temperature 25c
    Speed: 1333MHz
    Divider "Ratio": 2:10
    Timings: CL9-9-9-24 74 1T


    4GHz
    Processor: Intel Core i7-980X
    Core Voltage: 1.360V
    Temperature: 75c
    Core Speed: 4.0128GHz
    Uncore Speed: 2889.2MHz
    Base Clock Speed: 160.5MHz
    Quick Path Interconnect Speed: 2889.3MHz

    System Memory: 3x Corsair Dominator GTX 4 2533MHz 2GB

    Extreme Tweaker BIOS Settings
    Enter the system BIOS by presing Delete on the BIOS splash screen.
    Set Tuning mode to Exteme OC
    Set AI Overclock tuner to manual
    Increase CPU multiplier to 30X
    Enable CPU Load-Line Calibration
    Increase CPU voltage to 1.35V
    Set DRAM bus Voltage to 1.65
    Disable CPU Spread Spectrum
    Disable PCIE Spread Spectrum
    Advanced CPU confuguration
    Disable Intel speedStep
    Disable Intel C-State Tech

    Press F10 save changes and exit, press F8 and boot off of your MemtestX86 disk
    wait for atleast 1 full pass of error checking to complete before contunuing to boot windows

    if no memory errors found boot to windows and run Prime 95 Torture test select In-place large FFTs
    Install Core Temp we do not want the Maximum CPU temperature to exceed 80*C
    I recommend an error free pass of Prime 95 for 24hr to ensure system stability

    Random Access Memory Overclocking

    Now we move into memory overclocking
    Set DRAM Timing Control to Auto
    Manually change the DRAM clock frequency to the rating of you memory in this case *2133MHz
    Also change the DRAM voltage to match the rating of your memory *1.65V
    press F10 to save and exit.

    Boot into windows and open CPU ID to verify your memory clock speed.

    Run a stress testing program like Prime 95 or a quick test like Wprime
    To ensure stability I suggest creating a Memtest X86 CD to check for memory errors.

    Hi, my CPU is a i7-950 + 6gb 1866 RAM, I used this setting and my system got unstable. Also, my BIOS version is 1009, what settig shoud I use on my config?

    Thanks!

    not much, i started with 25x 145 = 3625.
    I made a bench with wPrime and my score was like 2x worst than the stock clock.

    All voltages I started at the minimum shown in the guide, you think i need to go higher with the voltages?

    Under CPU Management you need to enable Hyper threading "Intel HT Technology" this is disabling half of your Processor threads and giving you the experienced performance loss.

    CPU Voltage OCP "Over Voltage Protection" this limits the max value your can set for the CPU voltage

    A20M also known as "Gate A20" refers to memory addressing above 1MB- Enabling will enhance memory access speed, Disabling can lower performance but increase stability

    Hardware Prefetcher When enabled increases performance by pulling data likely to be required in the near future from the system memory (RAM) into the CPU cache before its needed to lower memory access times

    Adjacent Cache Line Prefetch When enabled increases performance by pulling "two" 64bit cache lines when "one" is requested by the CPU this reduces access time as an extra 64bit cache line is immediately available if needed
    This feature uses more bus bandwidth so performance gains may not be seen in all applications.

    CPU TM Function CPU "Thermal Management" Function throttles down the CPU clock speed this is primarily used for very hot chips to help keep them cool but lowers CPU performance

    Execute Disable Bit Also known as CPU XD, prevents the CPU from executing code in "Data Only" areas of Memory, this is a protection feature to help prevent "Buffer Overflow" attacks on the CPU

    Here's some questions.. so if I start the multiplier at 29x, bclk at 145mhz and cpu voltage at 1.4v and it crashes, do I *just* bump bclk and try again? then if it still crashes bump the voltage an increment and try again? Stepping upwards until stable?
