What your settings? i'm @ 0.50%
same for AGP spectrum .
In the Bios.

I honestly don't think its very significant. I've read reputable sources claim its best to turn it off. I've also read just recently to keep it at 1.00%. Mine is like your's 0.50%.

I'm so dense that I have no idea what you guys are talking about here! Anyone wanna explain this to me in like, really small words that you'd hear every day in a shot & a beer joint?

FSB Spread Spectrum
Common Options : 0.5%, 1.0%, Disabled
Quick Review
This BIOS feature allows you to reduce the EMI of the front side bus (known alternately as the FSB or processor bus) by modulating the signals it generates so that the spikes are reduced to flatter curves. It achieves this by varying the frequency slightly so that the signal does not use any particular frequency for more than a moment.
The BIOS usually offers two levels of modulation - 0.5% or 1.0%. The greater the modulation, the greater the reduction of EMI. Therefore, if you need to significantly reduce the front side bus' EMI, a modulation of 1.0% is recommended.
In most conditions, frequency modulation via this feature should not cause any problems. However, system stability may be compromised if you are overclocking the front side bus. Of course, this depends on the amount of modulation, the extent of overclocking and other factors like temperature, etc. As such, the problem may not readily manifest itself immediately.
Therefore, it is recommended that you disable this feature if you are overclocking the front side bus. The risk of crashing your system is not worth the reduction in EMI. Of course, if EMI reduction is important to you, enable this feature by all means. But you should reduce the clock speed a little to provide a margin of safety.
If you are not overclocking, the decision to enable or disable this feature is really up to you. But unless you have EMI problems or sensitive data that must be safeguarded from electronic eavesdropping, it is best to disable this feature to remove the possibility of stability issues.
Oh, and....

I disabled it because my CPU is clocked - 2800+ Athlon @ 2.2Ghz - and it makes no noticeable difference to performance.

my min.fps dont drop below 10 since i disabled spread spectrum and game runs smooth now. Strange but true.
