Jasper-based Xbox 360s beat RRoD problems

New info on RRoD causes

The new 360 graphics chip is also notably cheaper, which has allowed Microsoft to slash the costs of the console to the consumer right back for Christmas 2008. Newer models also have a 150-watt power supply, while earlier versions used 175 watts.

Takahashi has some new information on what caused the 360's RRoD. He claims that:"The main failure cause was "thermal fatigue" of the leaded C4 connections between the graphics chip die and its organic carrier.

"The underfill had too low a glass-transition temperature for the amount of heat generated. That caused cracking over time, resulting in graphics chips coming loose."
