Spread Spectrum & Bios.

[Big Lar]

I've noticed quite frequently that there are some inteligent people who post here, and I have a question that I can't seem to get a grip on. Maybe someone here can help. I just purchased a BXMaster Motherboard, and in the CPU settings for Overclocking, is a setting called Spread Spectrum. I had noticed the same setting on my BE6-2, but even while fooling with it,( toggling it from enabled to disabled), I didn't se any real world difference in the setting, However, with the BXmaster, There seems to be more speed with this function Enabled. If anyone could explain what this setting actually does, I would highly appreciate it.
Thanks

Here is (http://whatis.techtarget.com/WhatIs_Definition_Page/0,4152,213041,00.html) an explanation of Spread Spectrum as used in radio communications. An interesting note is that it was invented by Austrian-born Hollywood actress Hedy Lamarr.

In a microcomputer, it means the clock frequency is intentionally jumping around a bit instead of sitting nicely on the exact frequency. This is done to reduce RFI ~ Radio Frequency Interference. MicroStar recommends it be Disabled for overclocking to obtain greater system stability. - Elf

Elf is correct. High-end cordless phones are also now using spread-spectrum, meaning they're broadcasting on a continually changing frequency. That means things like scanners can't lock-in on their frequency.

BTW, some of world's best theorists/theoretical physicists say that any alien civilizations communicating over the vast reaches of our universe would be using spread-spectrum technology. Which also means the SETI project is a complete waste of time.

TY Elf, Outpatient, Time for me to change that setting, thanks again for the fast and informative replys http://sysopt.earthweb.com/forum/smile.gif

I believe the SETI project was started to listen for ET's trying to communicate to us. That's the reason why they use the frequency of 1.42ghz, same as Hydrogen which is the most abundant known element in our universe.
