Why is the CPU voltage inconsistent

 asked: My Computer CPU nominal voltage of 1.7V, why the BIOS measured out is 1.77V (I did not adjust the voltage), please tell me what is going on? In addition, I would like to ask whether the CPU down-frequency use of the system has a bad effect?

 A: Motherboard BIOS measured CPU temperature, voltage equivalent, by various factors, such as power supply, motherboard quality, CPU individual differences, and not necessarily with the nominal value of the CPU exactly the same. From your actual situation, should be within the error range, the normal use of no impact.

 in most cases CPU frequency reduction use is not any harm, you may use it with ease. But this is not absolute, we know that 100MHz, 133MHz down to the common standard FSB, the use of standard FSB motherboard PCI bus speed automatically for three-or four-frequency, keep the standard speed of 33MHz unchanged, However, if you reduce the CPU FSB from the standard 133MHz to 112MHz and other non-standard FSB, on some motherboards due to PCI bus speed may be higher than 33MHz, it is possible for graphics cards, hard drives and other accessories caused adverse effects.
