Not a peep about this anywhere but I happened to be mining it for a while before it happened and made out well, over and over.

$10-$30 amounts, pm offers.

Thanks

I've been playing with these cards for quite a while, tracking every change in config and it's affect and I think I've found the perfect CGMiner settings.


These settings get me 480 khash/s

So here are my settings, cards are running at low temps, reject rate is low and like I said 480 khash/s per card.

For under $200 a card, I'm quite pleased.

I hope this helps someone, cheers!

I'm about to pull the trigger on purchasing the parts for a mining rig and was trying to work out profitability. Using coinwarz and middlecoin I came up with these figure.

Do you guys think I'm in the ballpark?

I didn't see any posts on this, has anyone else tried this out for fun?

I ran out my free credit with HP Cloud and AWS and decided to try Windows Azure. The prices fluctuate but you get $200 free credit and can get 20 cores going for about 100 hours at no cost.

I am getting about 4 khash/s for each core so 80 khash/s isn't bad for free and taking 15 minutes to set it up.

Once you're signed up, info on creating your VMs is here: http://www.windowsazure.com/en-us/manage/linux/tutorials/virtual-machine-from-gallery/

Use two 8 core Ubuntu 13.10 instances and one 4 core to get all 20 going.

Connect to each instance and run the below and you're ready to go.
