I think my favorite overclock was back in the early Conroe days when Intel first released the core m processor. I bought an Asus white book and after assembling everything and doing on a power-on test I immediately powered it off and did a pin modification to force the socket from 100 megahertz front side bus to 133 megahertz front side bus.
It was such a simple modification that netted me significant performance improvements and voided my warranty in the first 5 minutes.
When someone in the artist community says OC, it always means that, and nobody ever actually spells it out. So my thinking was, if there were as many artists on here as I thought there would be, someone might have one they could talk about.
