Of course, all this pinmod will be useless if you are not overclocking, so your motherboard should at least have an FSB adjustment to make full use of it. But the author mentioned that they will be adding FSB pin mod as well, though I am guessing it's just a bootstrap option change (i.e. 533MHz, 800MHz, 1066MHz, 1333MHz or 133MHz, 200MHz, 266MHz, 333MHz).
The Core 2 Duos bring the joy back for the Intel Overclockers with their easy to handle heat and ample of overclock head-room. However, the overclocking capacity depends as much on the motherboards paired with them. Some of the enthusiasts on a tight budget are stuck with a limiting motherboard , particularly in the voltage department. (ASRock Motherboard Users come to mind ;) ) Well now here's a way out for you!
You can basically over-ride the default voltage of 1.325v inherent on many of the Intel Core 2 Duo CPUs, E6300 to X6800, with a simple "pin-mod". Well yes, there are no longer pins on these LGA packaged processors... in fact that makes them easier to modify! All you need is some electrical insulation tape and some conductive ink!
