CPU/HT Reference Clock (MHz) 200
Auto Detect DIMM/PCI Clk Enabled
Spread Spectrum Enabled
CPU Voltage Disabled
NB Voltage Disabled
CPUNB Voltage Disabled
DIMM Voltage Disabled
Advanced Clock Calibration (Disabled)
This item can enable greater performance turning margin for the AMD Phenom
TM
Black Edition CPUs. The optimal gain can be seen in configurations that use high-
end CPU cooling solution in combination with elevated CPU core voltage (CPUVID)
value. The motherboards that support ¡ °Advanced Clock Calibration¡±-feature
should enable power delivery capabilities that exceed the 140W CPU TDP specifica-
tions in order to maximize the performance tuning potential.
