1  Alternate cryptocurrencies / Altcoin Discussion / Pump n Dump - Textbook Example on: April 19, 2014, 12:29:10 AM
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.

3  Alternate cryptocurrencies / Mining (Altcoins) / The Perfect Gigabyte R9 270 CGMiner settings on: February 11, 2014, 02:53:40 AM
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.

"api-listen" : true,
"intensity" : "19",
"vectors" : "1",
"worksize" : "256",
"kernel" : "scrypt",
"auto-fan" : true,
"temp-cutoff" : "85",
"temp-overheat" : "75",
"temp-target" : "70",
"expiry" : "10",
"gpu-dyninterval" : "7",
"log" : "5",
"queue" : "0",
"retry-pause" : "5",
"scan-time" : "5",
"scrypt" : true,
"temp-hysteresis" : "3",
"shares" : "0",
"shaders" : "1792",
"thread-concurrency" : "16000",
"gpu-thread" : "1",
"gpu-engine" : "1125",
"sharethreads" : "32",
"lookup-gap" : "2",
"gpu-powertune" : "20",
"gpu-memclock" : "1500"

I hope this helps someone, cheers!
4  Alternate cryptocurrencies / Mining (Altcoins) / Mining Rig Profitability on: January 11, 2014, 02:13:50 AM
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?



5  Alternate cryptocurrencies / Mining (Altcoins) / Mining with Windows Azure Cloud Service - 20 cores free for 100 hours on: January 02, 2014, 07:58:26 PM
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.


sudo apt-get update
sudo apt-get install build-essential libcurl4-openssl-dev
wget http://sourceforge.net/projects/cpuminer/files/pooler-cpuminer-2.3.2-linux-x86_64.tar.gz
tar xzf pooler*
