May I join in
I was playing with these values recently but
unfortunately...my GTL gettings has become +-mv which allow fine tuning but difficult to control. Spec as sig.
The problem is I was never be able to find out what the current values of CPU GTL Ref and NB GTL Ref are (especially on "AUTO") so I wonder where should I start with...
I've heard alot of overclockers said CPU GTL Ref. don't have much effect with Dual Core chips. Is that true...if so..seems I'm wasting my time messing up these settings

Adjusting the CPU GTL Ref. will case wierd screen display, frequent crashes in programs:
CPU GTL 0: auto
CPU GTL 1: -5mv
CPU GTL 2: auto
CPU GTL 3: -5mv
NB GTL: auto

VTT was about 1.28v, can someone please tell me why this would happen? Any help would be much appreciated.
