Why can't the sound of the sound card come out when the computer is overclocking

Q: My Computer motherboard is the elite, integrated sound card, CPU is Celeron Ⅱ900mhz. When I overclocking to 1035MHz, into the system, the sound is not coming out. Bring the FSB back, and the sound is there again. Excuse me, what is the cause of this?

Should the CPU overclocking to 1035MHz, the system uses 115MHZ non-standard FSB, PCI bus frequency from the original 66MHz up to 77MHz around, which makes all PCI bus devices are operating in an abnormal frequency. Not only the sound card, graphics, memory, hard disk, optical drive, etc. may not work normally, but the sound card performance is more obvious. To avoid the impact of overclocking on other computer parts other than CPUs, it is recommended that you use standard FSB (such as 133MHz) as much as possible to ensure that your sound card works stably.
