何谓展频（Spread Spectrum）？

技嘉主板如何在BIOS下关闭展频(Spread Spectrum) 功能？

Spread spectrum simply means that data is sent in small pieces Over a number of the(46)frequencies available for use at any time in the specified range. Devices using(47)spread spectrum (DSSS)communicate by(48)each byte of data into several parts and sending them concurrently on different(49). DSSS uses a lot of the available(50), about 22 megahertz (MHz).

Spread spectrum simply means that data is sent in(66)pieces over a number of the discrete frequencies available for use at any time in the specified range. Devices using(67) spread spectrum (DSSS)communicate by splitting each(68)of data into several parts and sending them concurrently on different (69), DSSS uses a lot of the available(70), about 22 megahertz (MHz).
