This is almost certainly due to RAM timings and CRC checks were implemented and it fails repeatedly. My xcodes are based on cromwell and dont appear to do exactly what retail does.

Forcing some RAM timing from a 1.6 retail console improved things but there is more work here.

I added this in xcodes.
