Not sure what I am missing, but what screw are you using to attach the Nepton 280L cooling head to the board, nothing seems to fit.
I used the shorter set of screws that came with the Habaneros, combined with the little black plastic spacers from the Nepton 280 Kit.

Only got the boards here :|
Batch 1 thing maybe. $250 more but came with socket cap screws. Cost was easily offset by a similar amount of mining profits and having fun sooner than everyone else.

As for your trouble - the only time I've seen the regulator programming error is when there is an issue with power.
Have you tried a different PSU? What's your mining platform? What's your commandline to launch cgminer?
Have tried a different PSU, but same gigampz breakout board (will try another breakout board now).
Mining platform is Ubuntu running cgminer 4.4.1.
cgminer --hfa-fan 100 --hfa-temp-target 0 --api-listen --api-network --hfa-temp-overheat 106 --hfa-hash-clock 100
