Tonasket, initially known as Jasper_B, is the successor to the Jasper_A1 motherboard, and is the final motherboard used in the Original Xbox 360 series.

Commonly referred to by the community (but not by Microsoft) as "Kronos", a reference to the GPU used.

Notable Differences

  • The Zeus GPU has been replaced with the Kronos GPU
  • Samsung K4J10324QD-HC14 RAM was added as an option
  • Hynix H5RS5223CFR-14C RAM is no longer used
  • 8x64MB RAM configurations are no longer used, but still supported by the motherboard
  • The 256MB nand chip was no longer used, only 512MB configurations were used in the Arcade SKU
  • The additional traces and pads for DUMBO/PANDA flash controller were removed
  • An alternate simplified standby circuit for V_3P3STBY and V_1P8STBY was added, but only some manufacturers used it
  • The board layout was cleaned up
  • All motherboards use the updated RF02 board
  • The extended GPU heatsink was reverted back to the low profile GPU heatsink
  • All boards now use solid state capacitors for the CPU and GPU output filters
  • There is no longer glue applied around the CPU and GPU
