My CPU is an AMD Phenom II  X 4 905e. Its (default) settings are:

CPU Clock Ratio 		(Auto) 2500MHz
CPU Northbridge Freq. 	(Auto) 2000MHz
CPU Host Clock Contr. 	(Auto)
HT Link Width 			(Auto)
HT Link Freq. 			(Auto) 2000MHz
Memory Clock 			(x6.66 ) 1333MHz

I set the DDR3 voltage to auto, now it shows about 1.58V. 
Testing will take a little bit. Thank you for the hint.
