Spread Spectrum?

post #1 of 17
Thread Starter 
I have seen a lot of posts recommending you disable spread spectrum as it interferes with overclocking. Before I do this I would like to know what exactly is spread spectrum and how disabling it will help.

Any help would be much appreciated.

spread spectrum basically creates minute changes to the frequency of the FSB or HTT to reduce the interference caused by RF waves. while this may be good for the average user these changes can cause instability when overclocked
post #4 of 17
Yes The spread spectrum modulates te FSB signal (minimally)

Meaning your FSB will minimally rise (faster) and lower (slower) a lot of time a second (don't know wich to be precise)

That minimal rise of the FSB is a certain reason for instability (when you've upped your FSB beyond what it's meant for

So do you think disabling it is a good idea?

yes definitly youll get a higher and more stable overclock i always disable any options in bios that i dont need
post #7 of 17
Definitely disable it unless you happen to have your PC next to huge magnets, a radio tower, or motors.
Once again...

Spread Spectrum, C1E, Cool and Quite, SpeedStep, Thermal Throttling/Monitoring, EIST, and anything else that tries to raise/lower stuff automatically is deadly poison to overclocking.

yes agreed, as everyone said, for the averager use do not disable it.

for overclockers disable it for higher overclock system stability

NO. Disable it in all cases unless you place your PC next to a large EMI or RF source.
