[MSI X58A-GD65] Overclocking, stabilizing and testing a Core i7 920

Question

Greetings,
I have overlcoked my i7 920 to 4.000 MHZ and I would like to run some tests just to be sure about it's stability.
The RAMS have been succesfully tested with Memtest86+ which is included in Ubuntu 11.10 distributions.
However,  blue screens rarely occur.
If my current knowledge does not deceive me:
a) The more volts the more stability, heat and power consumption rate
b) Green/eco, less power consumption, Intel states are cr*p, right? I use a Power Wattage meter and the watt consumption does not fall below 400 Watts (it's the same when it's overclocked).
c) In my own experience Intel Turbo (21x Multiplier), states cause instability

Looking for more advice/suggestions about getting more stability and performance
I know that overclocking is dangerous and can damage/destroy/cook the components such as the CPU, RAMS etc.
However, whatever happens it's my responsibility

Answer 1

Why are you using X.M.P. with Memory and Uncore being adjusted manually? What are the random BSOD codes? VDroop should be set to Low. PLL and CPU V. seem to be ridiculously high for a 4.0 OC. What does CPUID's CPU-Z utility show for CPU voltage? PLL, IOH, and ICH should only require the Auto setting.
