Multi dropping to 16x

post #1 of 7
Thread Starter 
Ok, I changed my multi to 45 and my vcore to 1.30 and didn't crash after running intel burntest. I pulled up cpu z and it showed my freq at 4500, but then as I was watching it dropped down to 1600. Is this some sort of bug, or power saving feature, or is my mobo underclocking my cpu so it doesn't fry itself. First time overclocker, so sorry if this is a dumb question.

It's a power saving feature. Turn off C1E and EIST in the bios.

Yup, turn off C1E and EIST in the BIOS

phew, was hoping it wasn't my new toy dying. If I leave it turned on will it automatically bump up performance whenever it is needed? Or should I turn it off regardless?

First time recent CPU user?

Everyone's actually wrong with their statements. It's called C-State; a power savings feature on Intel processors. Leave it on if you care about your electricity bill. From my experiences, it does nothing to conflict with any overclocks set unless you have a bad motherboard which causes lockups when it changes states.

I keep it enabled. I'd love to keep the voltage level down too, but my motherboard isn't so hot.

There's also no reason to disable EIST either..

C3/C6 states are disabled by defaults, C1E can do this, but EIST is to blame in most cases.
