I think it is a software error . it is about 1.450 v on vcore.
the cpu temp is 36°c
you can see clearly on this picture

have you tried stability of your overclock setting with intel burn test or prime95?

because, if your setting is not stable, one or more of your cores may fail or stop working during benchmark..

that's why it lower than default clock.

Could be mem multi clocked down.

what should i do?

have you disable c1e and cool'n quite feature in your mobo's bios..?
that's the reason for the multi clocked down..
don't forget to disable turbo core too..


how about stressing your processor..? is it stable enough..?
at least with prime95 blend for one hour....

I disable c1e and cool'n quite,but I can't find any option to disable turbo.
I enable the High performance mode.
and then I overclock it @3.8Ghz run cpu z it runs @800mhz，prime95(64bit) cpuz shows 800mhz,
but run super pi cpu@3.8Ghz
I am so confused
thank you for hellping me
