rofl was gonna say...
Beauchampy, its a step by step process to get a rig to run fast, stable,
lowest possiable voltage, case temps and yes did i mention STABLE? You got
alot to learn, type: 'overclocking cpu' in google/yahoo/blah blah and start
reading, that probally the best advise you'll get, cept for 'dont do it if
you dont know what your doing'...
