The MadShrimps crew have been up to some serious overclocking it seems. They've putting an FX-55 through its paces & producing some serious results. Of course, don't try this at home; that is, unless you've got ready access to LN2 & another FX-55 ;)

"When you have the fastest CPU (at stock speeds) on the planet, you just have to push it further, although phase change cooling can get your underway, LN2 is bound to give you the edge. Let´s pour a few litres on this blazingly fast A64 FX-55 to see how high it can fly."
