Intel i5 3.1 clock speed voltages

[Renshaw]

Hello all I've built a new system and played with the software from Asrock who make the board that controls the clock speeds for the CPU... Like an idiot I've caused the system to keep locking up,I do not know what the orginal values are for each box on the page

in the program the option to change are as below.

Clock:-

Frequency

CPU Ratio

GT Frequency

Voltages:-

Cpu ofset voltag

Dram

PHC Voltage

Vtt voltage

Cpu pll voltage

Vccsa voltage

Igpu voltage offset

If someone could help this would be brilliant :)
