Following up on the Conroe news, Nordic Hardware has a crazy overclocking article here. With a cascade they get the chip up to 4.73 GHz and with LN2 they're up to 4.95 GHz!

DreamHack Summer 2006 has come to and end and most of us from NordicHardware has just arrived at home or are on the verge of it at least. Some of the people who kept going to the very last minute at DH in NordicHardware's booth was Kinc and Crotale which seemed impossible to separate from their bench system, which actually didn't receive its final ingredients until Monday evening, an Intel Core 2 Extreme X6800 and a cooler ambience after moving into Elmia's C hall. The last hours were used solely to pressure the system to the outmost limits and already during Monday we could report that they'd reached 4.8GHz with SuperPi 1M by using a compressor cascade cooler with about -100°C on the processor. This speed was enough to achieve the second best SuperPi 1M time in the world at 10.735 seconds, a very impressive achievement.
