******Motherboard Voltage Control******

Load-Line Calibration: disabled (can be used if volt drop is to big at higher core speed. (I always use LLC when overclocked)

CPU Vcore: The voltage applied to CPU @ varying speeds in order to achieve stability

CPU Termination: 1.20 aka "FSB voltage", keeps your system stable at a certain bus speed, higher bus, higher CPU Term

CPU PLL: 1.50 (it helps you to boot into OS, higher bus speed, higher CPU PLL) 1.50 is good enough up to 450 FSB with a quad

CPU Reference: 0.760 (aka CPU GTL Ref, set this value when CPU Term is at 1,20 because it changes/scales with the CPU Term, this one is a bit tough to explain but in short, this one helps to have the CPU stable when increasing bus speed)

MCH Core: 1.20 -1.30 (aka NB voltage, this P45 setting is a bit sensitive, both too low or too high and it will not boot)

MCH Reference: (0.840?) (aka NB GTL Ref, set this value when CPU Term is at 1.20 because it changes/scales with the CPU Term, this one is a bit tough to explain but in short, this one helps to have the NB stable when increasing bus speed, this one is also a bit sensitive, one step up or down should be fine though)

MCH/DRAM Reference: Auto (reference between NB and ram, best set to auto) I use normal

ICH I/O: 1.50 (aka SB bus voltage, one or two steps up if you run raid or many HD)

ICH Core: 1.10 (aka SB core voltage, one or two steps up if you run raid or many HD)

DRAM Voltage: You know what to set for your ram

DRAM Termination: auto (termination voltage for the ram) I use normal

Channel A Ref: auto (reference voltage for ram slots A) I use normal

Channel B Ref: auto (reference voltage for ram slots A) I use normal

And nice job Serg!!!!!
