images/news/xbox.jpgRROD is caused by anything that fails in the "digital backbone" on the mother board. Also known as a core digital error. CPU, GPU, memory, etc. Bad parts, incompatible parts (timing problems) bad manufacturing process (like solder joints), misapplied heat sinks or thermal interface material, missing parts, broken parts, parts of the wrong value, missed test coverage. Any one or more, on any chip, or many other discrete components, would cause this. And many of the failures were obviously infant mortality, where they work when they leave the factory and fail early in use. The main design flaw was the excessive heat on the GPU warping the mother board around it. This would stress the solder joints on the GPU and any bad joints would then fail in early life.
There are also other significantly high failure rates in other areas, like the DVD.
Q: So what do you think the real failure rate of the Xbox 360 is? Some have estimated it as high as 30%. I got my Xbox in early 2007 and so far so good but what do you think the chance is that it's going to die on me one day.
It's around 30%, and all will probably fail early. This quarter they are expecting 1 M failures, most of those Xenons. Some of those are repeat failures. Life expectancy is all over the map because the design has very little margin for most of the important parameters. That means it's not a fault tolerant design. So a good unit may last a couple of years, while a bad unit can fail in hours. I have a launch unit and have not had a single problem with it. And it's used a lot. But I don't know anyone else with a 360 that hasn't broken, except you now. There's no way to tell when yours might die. But the cooler you can keep it, the longer it will probably last. So stand it up, keep it in free air, etc. :Note : Xenon was the code name for the first Xbox 360 mother board.
