Overclock NVIDIA G210M & NVIDIA 9400G M GPU’s In A Dell Studio XPS 1340

This weekend I was investigating the capabilities of the two NVIDIA graphics cards in my laptop and a password cracking application called oclHashcat. The oclHashcat application uses OpenCL, the Open Computing Language, to utilize the processing power of your graphics cards GPU’s to crack passwords. My laptop is a Dell Studio XPS 1340 which utilizes Hybrid SLI technology to offer a good amount of graphics power while using the least amount of battery life possible. The laptop accomplishes this by mostly using an NVIDIA graphics card, which is a NVIDIA 9400G M, that is installed on the motherboard and only calling the second graphics card, which is a NVIDIA G210M, when it needs to render something in say 3D or higher quality than the 9400G M is equipped to handle. One thing I happened upon during my research was an NVIDIA utility that will easily allow you to overclock your NVIDIA graphics cards which I describe in more detail below.
