Notable Differences

• The 90nm Waternoose CPU has been replaced with the 65nm Loki CPU
• Around March 2008, fixed GPUs started being used in some units, but was not universally used until roughly June/July 2008.
• When the revised GPUs started rolling out, all board started using Qimonda HYB18H1G321AF-14 RAM in a 4x128MB config
• Qimonda HYB18H512322AF-13 RAM has been replaced with Qimonda HYB18H512321BF-14
• When the revised GPUs rolled out, Hynix HY5RS123235BFP-14 and Qimonda HYB18H512321BF-13 RAM are no longer used
• The V_CPUCORE voltage regulation is now 2 phases, down from 3 phases, but the pads and silkscreen for the third phase still remain
• The V_CPUVCS rail was added for the Loki CPU
• The board layout has been modified to support the Loki CPU
• The J7G3 Titan connector on the front of the motherboard was left on the final motherboard
• Some later boards use solid state capacitors for the CPU and GPU output filters
• The heatpipe CPU heatsink was replaced with the aluminum CPU heatsink, however some early boards did not have this change

Opus

The Opus name describes a project of fitting a Falcon board into the casings for a Xenon. This was done with a custom A/V port, and the removal of the HDMI port. Opus was used for refurbishing defective consoles until the Elpis boards started being produced.

Notable Differences

• Removal of the HDMI port
• Custom A/V port to fit the HDMI board layout while being able to fit into the Xenon casing
• All Opus boards use revised versions of the Rhea GPU with higher Tg underfill
• All Opus boards use 4x128MB Qimonda HYB18H1G321AF-14 RAM
