|Maybe "lightweight" wasn't the best term. What I meant was the hardware requirements aren't extremely high - your system far exceeds the minimum required.|
Can't help you with overclocking if you don't answer the questions:
- make/model of motherboard?
- speed of RAM?
DDR2 is not the speed, it's the type. Is it DDR2-667, DDR2-800, DDR2-1066, etc?
