Besides what's already been mentioned, I'm not sure why you'd bother overclocking anyway. You won't notice any difference in today's games and programs on such an old chipset. This is exactly why I returned my 8-year old Core 2 Duo E8400 former gaming rig back to stock 3.0GHz from an overclocked 4.2GHz state used for a few years. Makes no difference for today's applications since newer tech is so far advanced. It's also a waste of electricity and just a way to early kill an otherwise decent general use chip (Youtube, Office, email).
