CPU main power supply 1.5V ~ 1.75V, the third line of the fourth pin is a reset signal, 1.5V ~ 0V of hopping, the contractor will do their normal, measured it at boot watch the moment whether there is voltage hopping. The third line of the fifth needle called POWS lines, good signal voltage 2.5V, the voltage of the specific good signal, the generated voltage is not the same as, whether it is 370 motherboard, or 462 or 478 motherboard
motherboard, it signals the general good of the edge gray lines are from, or arising from the power supply IC, the first line of twelfth pin is a benchmark job clock, 14.318M Hz, operating voltage is 1.1V ~ 1.6V, the base clock by the clock chip job to provide, if not normal When we as long as the overhaul of the test points to the clock circuit between the resistor to see if this little damage, is also working clock, the clock does its work is the first column of the eighth and ninth pin, and its operating voltage it is 1.1 V ~ 1.6V, provided by the clock chip, the third out of the ninth pin, and the tenth pin is also the two clock, its working voltage is 1.1V ~ 1.6V, then by the clock chip to provide them separately, and this 462 motherboard is the key test points, when we do not work, CPU time, that is to say when the test card appears FF00, the focus has to check the CPU is that part of the working conditions, working conditions, when a problem appears after along the circuit-related damage to identify the relevant components, 478 motherboard, which is the key to P4 motherboard CPU test points, P4 motherboard so that it is only a lack of needle mouth, missing the mouth of the direction of the needle it up, then it , keyboard and mouse population down, and none of the places the needle at the top left, second row the first needle, VCC are the main power supply, operating voltage 1.5V ~ 1.75V, this job is the countdown clock the first column of the left fourth needle, and its Operating voltage is 0.4V ~ 1.0V, this is, the CPU and other key test points different from the other are 1.1V ~ 1.6V, then have the first column of the penultimate fifth needle, but also a working clock, is 0.4V ~ 1.0 V, from beneath the penultimate line of a few, from the left side of the fifth RESET pin is a reset, 1.5V ~ 0V, measured at the boot moment whether there is voltage hopping. Countdown to the fourth line of the left fifth pin is a PG signal, power good signal 2.5V, in order to do that we talked about, memory slot, PCI, AGP slot, CPU, such as have some of the key test points, stresses at these The key test points of time to do so, they have a test for the same point, they all have this power supply, clock, reset, then after the equipment is not normally encountered in the work of time,
