Disabling Spread Spectrum on a K8N Neo2 platinum?

Anyone know how to do this? I unlocked the extra options in the Cell Menu with Shift-F2, Alt-F3, but "Spread Spectrum" is still highlighted in blue and I can't even select it. When I looked in my manual, it also simply skipped over it.

Do I need to flash to a new bios to be able to access it? I'm currently running 1.36beta.

Thanks!
UWS

Are you overclocked? I have a K8N Neo 754 and I can only select this option at 200MHz and 205Mhz (not sure why 205). Any other setting and it's disabled.

I have a k8n as well and it lets me alter it
why do you want it off by the way? I found that it interferred wth my sound card when it ws off and I got a high pitched buzz at high volumes and it barely affects performance

The 'Spread Spectrum' setting is designed to minimize the amount of electronic 'noise' your computer throws out in the EM spectrum at a particular frequency. It does this by ever so slightly varying the base freqencies the components are running at. For example, a computer running with a setting of 200 MHz FSB and 'Spread Spectrum' on, might actually be running at a a speed of somewhere between 199.5 and 200.5 MHz and would be randomly changing that frequency constantly.

If you are running a highly OC'd system, this is a Bad Thing, because you are already pushing your system to the ragged edge of stability for maximum performance, and now you've got the system trying to, in essence, self destruct.

So, turning off "Spread Spectrum" allows you to achieve higher overclocks, at the expense of perhaps rendering your cordless phone unusable.
