"The one we have in our test rig at the moment is the Paradox, which is another variation using DIP switches. Once we got it in we were pleasantly surprised by it's small size. The Paradox sits alongside the back of the Athlon taking up little vertical space. It has two sets of DIP switches, similar to the ones used by the Tweeking Device and the FreeSpeed Pro. There are 8 switches in all, the first 4 control the core voltage and the second set of 4 control the frequency."
