Guys...
Im having a problem here and i cant see to find the problem...

Im using guiminer because its fast and intuitive...
I have 2 rigs, both with 2 cards...

One rig is working ok, but the new one i have setup this weekend is giving me headaches...

I have everything correctly configurated on the CGMiner, but i cant see the accepted starting to add numbers...

When i do start, it will start the mining process, but it seems nothing happens... most of the time the accepted stays the same... or appears a new number from hours to hours...

im minin at 670 and 530 for both cards...

I cant see what could it be...

Can anyone help me out?

Best Regards,

LPC
