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.

AMT,
I got my brothers card and tried it on my machine this morning. The top card is still dead and the hashing on "one" of the other cards looked better this morning. However I did notice that on the card that seems like its not hashing fully, the heat sink is not properly placed on the card (its lifted up from one side). So it may be that the heat on the chips on that card are overheating which causes the card to not fully hash.

Let me know if and how I should return the top card as its not turning on at all. I will let you know what the other cards hash rate it later on when I get back home.

Thanks in Advance.

AMT,
So to summarize here are my current machine's standing...

1. Top card is completely dead - Never worked
2. Second card is only partially hashing - Never fully hashed. This is the card that its heat sink doesn't look like its fully seated from one side.

Let me know what I should do to further troubleshoot or if I should return the cards or unit?

Thanks in Advance.

Download this image, write to an SD card using win32 disk imager, and replace the existing one in the PI. See if that helps.
