Stable overclocking fails on PC reboot

[misterbeam]

Hello,

I overclocked my 6600K to 4.7Ghz, and made sure it's stable using a long realbench stress test, but whenever i restart my computer the overclocking fails, what could be causing this ?

Thanks,

More than likely your memory overclock isn't stable.

Are you using the XMP profile or manual memory bios settings?

Unstable overclock. You need to finetune it some more.

I am using XMP profile.

EDIT: you were right!

I'm already @ 1.36V on the Vcore, don't wanna go further :D, but i will try higher LLC setting, maybe it will help.

Enabling XMP profile is overclocking in its own right. So you need to make sure your instability isn't caused by running memory at 3000MHz.

It is memory indeed, i'm even running lower cpu voltage now 1.34V, but with 2133 MHZ.

Running memory at lower speed usually doesn't require as much voltage on the Vcore as with high speed kits.
