trouble with poclbm (shows only a couple of MHash/s)

[yigga]

first off, if this problem was solved before, please point me to the right thread, but i couldn find anything similar

I have trouble setting up poclbm.

i only get a 2MH/s hashrate. tried it with the dos promt (cmd.exe) and guiminer.

i checked both my gpus device=0 and device=1
it seems poclbm cant detect the gpus.

everything runs smooth with phoenix, but i was wondering if i could mine more efficient with poclbm.

Any help advice appreciated.
