Optimizing Your Phenom II Overclock For Efficiency

Settings: 3.4, 3.6, And 3.8 GHz

Phenom II X4 940 BE @ 3.4 GHz

The 3.4 GHz setting still was reliable at automatic CPU voltage settings. The Jetway system nevertheless applied 1.375 V (CPU-Z shows 1.392 V).

Phenom II X4 940 @ 3.6 GHz

The 3.6 GHz setting required a slight increase in CPU core voltage to 1.40 V, as the 1.375 V that was applied by the automatic mode didn’t gurantee stability.

Phenom II X4 940 @ 3.8 GHz

3.8 GHz was the fastest reliable setting for our Phenom II X4 940, and we had to increase the core voltage to 1.5 V to realize stability. Unfortunately, we were not able to hit 4.0 GHz no matter which voltage we chose.
