These should be getting 300 if not 400 each!

This is running "phoenix.py -k poclbm DEVICE=1 AGGRESSION=3"

When I run poclbm.py it runs for a little bit then says:

283051 khash/s

Update -- switched to:
./phoenix.py -k poclbm DEVICE=2 AGGRESSION=7 BFI_INT VECTORS

And now at 350 MHhash on each card.

Better. Not perfect... but acceptable for now :-)

What are you using for workload size? Should be -w128.

IMO if memory is underclocked at 300 MHz -w256 gives better results
