With a non-modified ASUS P5B motherboard they managed to reach a whopping 7520MHz, but pointed out that the motherboard made it impossible to go any further. Now that they have once again mounted the copper pipe and made the necessary voltage modifications, the liquid nitrogen once again did its thing and made it possible for them to finally reach 8000MHz!
Big congrats to OC Team Italy for this crazy acheivement. Bare in mind that this is originally a 3.0GHz chip and now retails for around $100. It’s hard to top a 266% overclock!
