no I double checked. in fact I've been checking everytime I type it wondering if it was something so stupid.
./phoenix.py -u
http://username.workername:workerpassword@api.bitcoin.cz -k phatk DEVICE=1 WORKSIZE=256 VECTORS BFI_INT AGGRESSION=7
for slush's pool
&
./phoenix.py -u
http://user@email.com_workername:workerpassword@pit.deepbit.net -k phatk DEVICE=1 WORKSIZE=256 VECTORS BFI_INT AGGRESSION=7
for tycho's pool
I just kept getting fail to connect retrying. there is no reason for this to fail if poclbm is able to connect properly no?
*Anyway I'm still wondering about the underclocking for memory

you have missed something, the port

it should be like this:
./phoenix.py -u
http://username.workername:workerpassword@api.bitcoin.cz
:8332/ -k phatk DEVICE=1 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=7
not this:
./phoenix.py -u
http://username.workername:workerpassword@api.bitcoin.cz -k phatk DEVICE=1 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=7
you can also use poclbm instead of phatk, i get more hash/s when im using poclbm:
./phoenix.py -u
http://username.workername:workerpassword@api.bitcoin.cz:8332/ -k poclbm Device=0 VECTORS AGGRESSION=13 WORKSIZE=128 BFI_INT FASTLOOP=false
