[SOLVED] VRM Spread Spectrum - does anybody use it? {M5A99X EVO}

post #1 of 15
Thread Starter 
Hello

my issue is about VRM Spread Spectrum
does anyone use it?

I tried to turn it to ENABLED
but then my memory (KHX1600C9D3K2/8GX) works only on 1333MHz

It should be enabled. It reduces emi output from the vrms.

It shouldn't have anything to do with memory though. Maybe it's a bug. Have you looked to see if there is a new bios update for your board?

No, disable it.

It modifies the signaling to reduce EMI.... but unless you have EMI issues, that modified signals will have issues at higher clock rates.

Unless you are working in a radio lab or audio studio, there really isn't a need for it especially for home use.

It's DISABLED
simply because I can't get 1600MHz on my RAM

Well...

atm im having VRM Spread Spectrum set to ENABLED
my RAM runs at 1600MHz and all works properly

I just have KHX1600C9D3X2K2/8GX instead of KHX1600C9D3K2/8GX biggrin.gif



funny but on Kingston website KHX1600C9D3K2/8GX is recommended...

So what did it contribute to your system?

Huh? Enabling VRM Spread Spectrum makes your system faster?
