Hey, everyone. I am Wei, I am a freshmen here, and in LN2 overclocking too. I try to pull my P4 651 to an extreme frequency, but coldbug bothers me

.
For example, Sometimes coldbug is below -170 C, Sometimes coldbug is above -160 C. The VID gets higher, coldbug becomes higher too. Now I only get 459 X 17 = 7.8GHz at VID= 1.848V, about -165 C.

How to deal with the coldbug? Can Socket 775 be moded to past coldbug just like the Clarkdale? Please help!
