Coinmonkey has just received their 1st Gridseed ASIC Scrypt miner from GAW Miners. I’ve been fighting the Mid-West heat with my current GPU setup and this is the savior that I’ve been waiting for.

1st to get the 5 Chip Gridseed up and hashing on a MAC OSX I had to download Gridseed MacMiner.

You’ll have to run the following on a term window to get your Gridseed device name

ls -l /dev/cu.*

Look for something like : /dev/cu.usbmodem24111

When you launch MacMiner you have to use the following switches:

–freq=850 –gc3355=/dev/cu.usbmodem24111

As far as the hashrate goes, I wasn’t able to get MacMiner to display the correct hashrate for the Gridseed. Additionally, I found that Pools with higher diff’s showed a much lower hashrate for the Gridseed. You should expect 300kh/s+ from a 5 Chip Gridseed. These Gridseeds run very quiet and very cool.

I can’t wait to get my hands on a few more of these and finally be done with the GPU noise and heat in my apartment.

Here are the specs on the 5 Chip Gridseeds:

• Allows you to mine Bitcoin and Litecoin at the same time!
• 340 KH/s on Litecoin/Scrypt only, using just 5-7 watts of electric!
• Dual mode hashes up to 10 GH/s on Bitcoin and 200 KH/s on Litecoin using 60 watts!
