Phenom II X4 970 and Phenom II X6 1075T CPU Review
Overclocking
Contents
We did some basic overclocking with both CPUs. We used the AMD stock cooler and didn’t play a lot with all options available, so with more time and patience you may achieve results even better than ours. We ran Call of Duty 4 to test the system stability.
With the Phenom II X6 1075T we were able to increase its base clock from 200 MHz to 223 MHz, making the CPU basic internal clock to be 3,345 MHz, an 11.5% increase on its internal clock rate. In order to achieve that we had to reduce the memory multiplier, as it was the component limit our overclocking, and increase the CPU voltage to 1.300 V.
The Phenom II X4 970, on the other hand, proved to be a fantastic overclocker, thanks to its unlocked clock multiplier. We increased the clock multiplier from x17.5 to x21 and were able to immediately see our CPU running at 4.2 GHz stable. Then we played with the base clock, which we were able to increase to 206 MHz after increasing the CPU voltage to 1.425 V. The final result: 4,326 MHz, a 23.6% increase from the CPU’s 3,500 MHz default clock.
