Yes, the A5 has 264 cores on 33 chips (8 cores per chip).

One of my A5's is having a problem with 1 board so I'm only running at 2/3 capacity.

On my A5, on the left most board, the LED goes out as soon as the mining starts. Do your boards stay lit?

Can you post the entire output of --debug here?

Cheers,
