Extremly low Hash rate

[Betsi]

Hello,

I have a problem mining NMC. My system has 2 cards - 5770 and 6950 and while mining btc I usually get these hash rates: ~200(-v -w256) for 5770 and ~350(-v -w128) for 6950, however when I setup the GUI Miner to mine nmc I recieve these hashrates: ~2 and ~170. Do you have any ideas what may be causing this ?

Mining Namecoins is no different than mining btc. The only thing I can think of that is happening is you're trying to mine on only 1 card. I'm not a fan of GUI miner, I'd switch to phoenix with the phatk kernel for those cards.

Double check and make sure you're setting your device=# properly.
