The '''Elpis''' motherboard is exactly the same as the Xenon, with exception to the GPU, and the software. Elpis motherboards were used for refurbishing defective Xenons up until 2011.
=== Prototypes ===

Various part numbers have been spotted on stickers placed on the top edge of Elpis boards. They include:
There are 12 major versions of the Xenon motherboard. The production variant is the 11th version, Fab K (-011).

* The board uses the 7xxx series [[CB]] bootloader instead of the 1xxx series used on Xenon
** The reason for this is unknown as the 1xxx series bootloaders work just fine with Elpis

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
