I have already stated my Opinion on HT Overclocking with Phenom like 3 times already But will do it again......HT Overclocking on Phenom Means (MOOT) and should be avoided unless you wish to dial in you're Overclock Incrementally and get some added performance and speed by Increasing the HT Bus after you have a Established Base Overclock working Its only my opinion but lets think about this for a second shall we?

HT = Can Be Independently Clocked
CPU = Can Be Independently Clocked
NB = Can Be Independently Clocked
Ram = Now has Dividers to be set from 400MHZ - 1066MHZ to Establish (Base Overclock)

HT Bus = Should be used to Tweak you're Base Overclock Established By Independently Overclockable Components .......NB - HT - CPU - RAM
