* 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 [[Power Rails#V_3P3STBY|V_3P3STBY]] and [[Power Rails#V_1P8STBY|V_1P8STBY]] was added, but only some manufacturers used it
* The board layout was cleaned up
* All motherboards use an updated [[RF Board#RF02|RF02]] board
* The [[Heatsinks#Extended GPU| extended]] GPU heatsink was reverted back to the [[Heatsinks#Low Profile GPU|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

Notable Differences

A July 2009 Jasper with a Kronos GPU
  • The 80nm Rhea GPU has been replaced with the 65nm Zeus GPU
  • Hynix H5RS5223CFR-14C and Hynix H5RS1H23MFR-14C RAM were added as options
  • The XSB has been replaced with the PSB
  • Arcade Jaspers came with 256MB (later 512MB) nand chips that combine system storage and a Memory Unit
  • Traces and pads for an additional flash controller (referred to as "DUMBO" or "PANDA") have been added, but never populated
  • Other small changes were made to the board layout
  • Very late Jaspers manufactured in July 2009 come with the Kronos GPU instead of the Zeus GPU
  • Some of the boards no longer have glue applied around the CPU and GPU
