CWmike writes "Advanced Micro Devices on Thursday introduced the latest member of its Phenom II X4 family of high-performance quad-core CPUs, which the No. 2 chip maker said it had run as fast as 7 GHz in extreme overclocking tests. Out of the box, the new X4 955 Black Edition, which is aimed at gamers and hobbyists, runs at 3.2 GHz, giving it similar performance to Intel's fastest desktop chips at lower cost, AMD says. The company was able to more than double the CPU's speed during its tests using extreme cooling technology that is not safe at home, said Brent Barry, an AMD product manager. The Web site Ripping.org notes that hobbyists with early access to the X4 955 chip have been able to clock it at up to 6.7 GHz. AMD said the chip was safe with fan cooling at up to 3.8 GHz."

CarnegieScience writes "The most powerful earthquakes happen at the junction of two converging tectonic plates, where one plate is sliding (or subducting) beneath the other. Now a team of researchers, led by Teh-Ru Alex Song of the Carnegie Institution's Department of Terrestrial Magnetism, has found that an anomalous layer at the top of a subducting plate coincides with the locations of slow earthquakes and non-volcanic tremors. The presence of such a layer in similar settings elsewhere could point to other regions of slow quakes."

SailorSpork writes to tell us that the rumored LEGO Rock Band has been confirmed, and it's set to be released later this year. The game is being developed for the Xbox 360, PS3, Wii, and DS. The press release lists the first five songs selected for the game, and says players will "work their way through local venues, stadiums and fantasy locations on Earth and beyond, that mimic the imaginative settings that the LEGO world offers. Also continuing the LEGO 'build-and-play' gaming experience, players will be able to create their own LEGO Rock Band style as they customize their minifigure avatars, band and entourage, including roadies, managers and crew." A new page on the Xbox website provides more (slightly odd) details: "Play killer riffs to destroy a giant robot, summon a storm, and demolish a skyscraper using the power of rock!"
