During an event by AMD held at its facility in Austin, Texas, the engineers took an engineering sample of the unrealeased Deneb core based Phenom II X4, installed a copper-pot for liquid nitrogen cooling, and dropped the operational temperature to -185 °C. They then jacked up the vCore to 1.90V, to facilitate a clock speed of over 6.00 GHz!
At this point the exact frequency isn't known. Cameras weren't allowed at the event, and so no clear pictures were taken. Earlier the company had released slides to its channel contacts, telling that Phenom II would overclock very well, and 24x7 overclocks beyond 3.60 GHz on air didn't sound unreal. At the same event, AMD showcased Deneb chips doing 4.00 GHz with air-cooling (with vCore set at 1.6V).
