I wish I had a golden CPU, my X3370, albeit a quad, struggles to stay stable at 4 GHz

Hopefully I can get this sorted after my build is done and get to at least 4.2.

Some n00b questions:
What is VID?
What is VTT and what does it directly translate to in BIOS?

I'm sure it will take a lot more Q and A before I have a properly OCed processor.
