setting I used :
Ai Overclock Tuner - Manual
CPU Ratio Setting – 21
DRAM Frequency –1140
Intel Speedstep Tech - Disabled
Intel Turbo Mode Tech - Disabled
QPI Frequency – 190
PCIE Frequency - 100
UCLK Frequency – Auto
QPI Link Data Rate - Auto
DRAM Timing Control – 7 7 7 20

  1. I managed to get this apparently stable overclock (which survived successfully a x20 with Linx):



    As for my setup: I am using a Full Tower Thermaltake Element V which sports 5 fans (2x120 on the Front Panel, 1x230 on the side panel, 1x200 on the top and 1x120 in the rear), cable clutter is to a minimum since they are tied in order to grant a decent air flux.

    Other specs include:
    MB: Asus Rampage Formula II
    CPU: Intel i7-930@2.8 Ghz
    RAM: 3x2GB Corsair Dominator DDR3 PC12800 CL7
    Cooling: Cooler Master V8
    Case: Thermaltake Element V
    VGA: Nvidia GTX 275 (1896 MB)

    Currently the BIOS settings are like that:

    Anything which could improve my temperature (I idle at 41° and top 91-89-87-87° with Linx x20) without giving up further speed or stability?
