spread spectrum harmful to health?

[kankurou]

would disabling "spread spectrum" in bios be harmful to my health? cancer risks?

 

[Sylvanas]

No.

possible side effects include headache, drowsiness, nausea, dementia... if you overclock without spread spectrum, consult your doctor before trying lipitor. the surgeon general states women who are pregnant, nursing, or may become pregnant should not take lipitor while overclocking without spread spectrum.

I guess that depends on whether RF emissions in general are hazardous to your health. I don't think that anything has been proven yet, otherwise WiFi would be banned.

Then again, they thought smoking was safe too.

Why would it be??

 

[alyarb]

do stupendous magnetic fields or ionizing radiation come off the absorption of radio beams? has anyone gotten cancer from listening to the radio? i don't see how wifi is exempt from this.

Spread spectrum is not there for health reasons, neither to your health's benefit nor detriment.

Disabling spread spectrum will not effect your health anymore than enabling it has benefited your health.

Electromagnetic radiation - radio waves - are non-ionizing. The only thing that can happen from absorbing it is that you warm up.

Further information, in case anyone is interested:

Spread spectrum is a common way of reducing conducted emissions in modern switching power supplies. Instead of switching at a constant frequency, the frequency is varied - "spread" - over a set range.

The primary reason is for conducted emissions requirements for consumer electronics. Conducted emissions are measured by taking the quasi-peak value at different frequencies. Quasi-peak measurements are something like an average peak (see the Wiki article). The majority of conducted emissions come from radio sources, digital clocks, and switching supplies. Noise from switching supplies occurs at the switching frequency F and each multiple N*F for N=1 to infinity.

By constantly moving the fundamental switching frequency, the average noise at the multiples of the fundamental is reduced because the frequency is only at any particular value for a fraction of the time.

So, there you have the reason for spread spectrum power supplies.

yes, that's what i was saying.
