The Zephyr motherboard has 3 different versions with very minor differences.

Zephyr_A

Zephyr_A is the successor to the Xenon motherboard and is used in the Original Xbox 360 series. It is the first to feature HDMI.

Notable Differences

Zephyr_B

Zephyr_B is the successor to the Zephyr_A motherboard and is used in the Original Xbox 360 series.

Notable Differences

  • The Y1 GPU has been replaced with the Y2 GPU
  • The PCIe pads under the GPU have been de-swizzled in order to support the Y2 GPU
  • The extended GPU heatsink is always used, in place of the low profile GPU heatsink

Zephyr_C

Zephyr_C is the successor to the Zephyr_B motherboard and is used in the Original Xbox 360 series. The part number is the same as Zephyr_B.

Notable Differences

  • The Y2 GPU has been replaced with the Rhea GPU
