Athlon II 435 overclocking results
In order to test the overclocking performance we used the 3D Mark Vantage Performance test, since I am only really interested in seeing how overclocking the CPU can improve gaming performance. However, the 3D Mark Vantage scores are still a good measure of overall CPU performance. The graphics card we used was the Radeon HD 5870 1GB version at reference core and memory speeds.
You can see the results below:
As you can see the scaling is quite impressive. We were able to increase CPU performance in 3D applications by 27% which corresponds to the magnitude of the overclock which was also 27%. We were also able to boost the performance of the graphics card by a margin of 8% which is quite impressive, it shows us that the Athlon II X3 435 was bottlenecking the HD 5870 quite a bit at its stock 2.9GHz speeds but after 3.48GHz the HD 5870 starts to reach its full potential. The overall combined gain was 16%. It is worth noting the settings that we finally settled on before getting the 3.7GHz overclock stable on our Athlon II X3 435:
255 X 14.5 = 3.7GHz or 3700MHz
255 X 8 = 2040MHz for both the NorthBridge and Hyper Transit.
255 X 3.33 = 850MHz for the RAM speed.
CPU core voltage = 1.475V
