The option description:
By means of this information option you can learn current pressure of a food of chains of input-output of the processor. Rating value in most cases — 3.3 Century
At some realisations BIOS there is a colour allocation of the deduced information. If pressure within norm, you see dark blue figures if it left for admissible limits, colour of figures will be replaced with the red. It is quite often possible to refuse control of pressure of a kernel of the processor in general. For this purpose it is enough to choose for an option value [Disabled] or [Ignore].
Be not surprised to constant "jumps" of displayed value — accuracy of schemes of measurement of the motherboard far from an ideal affects. At the serviceable power unit stability of all pressure is at rather high level, to be convinced of it it is possible, having connected any normal measuring device (the voltmeter or an oscillograph).
