OC 960 1066 or 1333 what speed is better??

This is the list of voltages my board can do.

CPU base clock: From 100 MHz to 600 Hz in 1 MHz steps
PCI Express clock: From 90 MHz to 150 MHz in 1 MHz steps
CPU voltage: From 0.5000 V to 1.900 V in 0.0125 V steps
VTT (memory controller, QPI, and L3 memory cache) voltage: From 1.075 V to 2.015 V in 0.020 V steps
CPU clock voltage: From 700 mV to 1000 mV in 100 mV steps
CPU clock multiplier (PLL) voltage: From 1.300 V to 2.520 V in 0.020 V steps
PCI Express voltage: From 1.000 V to 2.140 V in 0.020 V steps
PCI Express clock voltage: 700 mV to 1000 mV in 100 mV steps
QPI PLL voltage: From 0.800 V to 1.600 V in 0.020 V steps
North bridge (ICH) voltage: From 0.920 V to 2.380 V in 0.020 V steps
South bridge (IOH) voltage: From 1.000 V to 2.000 V in 0.020 V steps
Memory voltage: From 1.300 V to 2.600 V in 0.020 V steps
Memory termination voltage: From 0.500 V to 1.205 V in 0.025 V steps
Memory data reference voltage (per channel): From 0.680 V to 0.950 V in 0.010 V steps
Memory address reference voltage (per channel): From 0.690 V to 0.950 V in 0.010 V steps

Dude, you put it at whatever it says on the sticker, not whatever you feel like putting it at.

I hope you don't have a sandy bridge cpu. If so 1.8v will fry the cpu.
