Here is something I found in another thread here on this forum :

"CPU Spread Spectrum: Modulates the processor clock to reduce radiated noise emissions. Disable if overclocking, as clock modulation will increase instability."

Not much to find about VRM Spread spectrum though, most I see on google is to disable it...

Me too, most say to disable VRM Spread Spectrum unless you are in a lab or something.

rep that bro....
nice find and I knew I had it disabled for a reason..

Disabling CPU Spread Spectrum is only necessary for enhancing BCLK overclocking.  If you're leaving it at 100.0 MHz, then there's no need to disable CPU Spread Spectrum.  The BIOS itself even says that disabling it "might enhance BCLK overclocking ability" (but it doesn't say that it will).

 

Any guide that recommends disabling it while simultaneously recommending leaving the BCLK at 100.0 MHz is simply going by the way it used to be when all overclocking was done by overclocking the FSB.  As some of you may remember, we had to disable Spread Spectrum, C1E and EIST in order to enhance FSB overclocking.  The same is true for BCLK overclocking.  Therefore, if you are not doing any BCLK overclocking, then there's no reason to disable these because it won't make any difference to your system's stability (because you're not touching the BCLK).  Disabling CPU Spread Spectrum while leaving the BCLK at 100.0 MHz doesn't make any difference to your system's stability or your overclocking potential.

But I thought that with Z68 boards keeping it enabled will produce a 99.8MHz BCLK?

Nothing has changed.  Pretend that I added this in the post:  "Of course, if you have the Z68 or Z77 chipset, then having CPU Spread Spectrum enabled can result in a BCLK of 99.8 MHz"

 

I guess I was just assuming that we all know this by now.

post #8459 of 9343
Hi to all...

I have the p8p67 rev 3.0 and i want to try using Lucidlogix Virtu mvp 2.0. I don't know if anyone has alredy asked this question because of the hundreds of pages XD
So, can i use Virtu mvp 2.0 on P67 chipset? Or it requires z77 chipsets?
post #8460 of 9343
It was never licenced for P67 chipsets.
