Mine does that too (2 clicks of vCore before CPU-Z shows it) Tool....it annoys the hell outta me. Although my 9550's a C1, i use :

CPU Clock Drive.................................[ 900mv ]
PCI Express Clock Drive.........................[ 900mv ]
CPU Clock Skew..................................[ 0ps ]
MCH Clock Skew..................................[ 0ps ]

I also use .63 on MCH Ref and CPU Ref(anything over. 65 crashes). Your VTT seems low...I need 1.38 VTT and 1.38 MCH for 4GHz(471x8.5).
