Xenon is the first motherboard and is used in the Original Xbox 360 series. The motherboard has a unique board layout compared to the later boards, especially noticeable with the capacitors around the CPU heatsink, and use of the ANA chip. The production board is known as Fab K, which is version -011.
Notes
- At some point in 2006, at least one of the manufacturers of the Xenon started applying glue around the CPU and GPU
- Some consoles use small yellow 820uF capacitors, while other consoles use silver 820uF solid capacitors
- Some capacitors used for voltage regulation positioned around the CPU heatsink are defective and prone to failure (see Capacitor Plague for details)
- There are two different versions of the XSB southbridge used, initially G0, and later switching to R0
- At some point in 2006, the extended GPU heatsink started being used on some systems instead of the low profile GPU heatsink
