AMT,
With my 4 cards working I'm getting a lower than expected hash rate. Can you let me know what to do to troubleshoot why the cards are working at a lower speed? I'm only getting an average of 730 GH. The 5th card is not attached right now since it doesn't work.
Let me know,
Thanks in Advance.
Just a quick idea before we get a technical answer on this. Get your brother to copy the card from his miner flash an sd card with the copied image. You can use win image 32 for making the copy.
