Samsung Galaxy S II is already a very fast smartphone @ 1.2 GHz. And it can be even better and faster by overclock it to 1.4 GHz or 1.6 GHz. That’s 17% and 33% speed increased. However, official kernel does not support overclock ability as the highest speed stage is locked at 1.2 GHz. Basically, you need a custom modified kernel which have more and higher speed stages to overclock. And use SetCPU application to overclock it.

Overclocking is not a stranger to me. I overclocked my old Intel Core2 Extreme quad-core processor QX9650 to 3.6 GHz. And I can overclock my HTC HD2 with SetCPU’s help too. SetCPU is CPU speed tweaking application for Android. In details, it allows control of certain aspects of the Linux cpufreq driver by allowing for overclocking, underclocking and tweaking speeds. It works on most rooted Android 1.5, 1.6, 2.0, 2.1, 2.2 builds.

Introduction
After AMD took over ATI… ATI Radeon HD 4800 series broke lot of benchmark scores and they are selling at a very attractive price range too. There are lot of model in HD 4800 series like 4830, 4850 and 4870. And we have 512MB, 1GB and 2GB version of video memory to choose from. Not to mention X2 series like 4850 X2 and 4870 X2. There one that I have is Sapphire ATI Radeon HD 4870 Silent Efficiency 512MB GDDR5 PCI-E. How does it perform? Read on to find out…

GPU-Z ~ a free utility designed to give you all information about your video card and GPU. It provides displays adapter, GPU and display information. It also provides displays overclock, default clocks and 3D clocks. I use it to trace my ATI HD 4870 GPU temp and fan speed. It has log to file function. Therefore, you can trace these during game play.

Prime95 is also known as Great Internet Mersenne Prime Search (GIMPS). It is a tool to find World Record Primes. However, it can be used as CPU torture tool as well. It is a great tool to stress your CPU because the torture test will use up all your CPU core and 100% CPU utilization. Who want to torture his own CPU anyway? Overclocker like me will need it. Besides this tool, I also use SpeedFan to monitor CPU temperature and CPU-Z for CPU core speed and bus speed.
