new to phoenix and linux mining

just got a linuxcoin .2b worker up

phoneix.py  -v -k poclbm BFI_INT FASTLOOP=false AGGRESSION=11 DEVICE=0 WORKSIZE=128

on my 6950 2gb @ 840/1000 is pulling 315 hash.

seems a little low, my 6950 on my win7 box and guiminer is doing 330 with lower mem settings(and a lower fan speed in a hotter room)

is it low or am I just too used to staring at my 5870 miners?
