Dogecoin Mining rig and other Cryptocurrencies

dogecoin mining rig

I recently build a Dogecoin mining rigĀ and decided to write a blog post about it. This rig can be run for other scrypt coins such as Litecoins.

I felt this is both a hobby for me and an investment that generates some small returns for both the short run and long run.

Below is a quick schematic I drew up of how to put together the dogecoin mining rig. I didn’t include the hard drive in my costs since I just pulled out an old HD from a computer I had years ago that wasn’t being used.

Dogecoin Mining Rig Schematic

For the Operating system, I used a Windows 7 key I had bought back in 2009 under the student program. Since that key wasn’t being used, I applied that to this system. Assembling all the pieces together, my rig looked something like this.

The dogecoin mining rig in the above picture doesn’t show the hard drive since I was using a USB stick and Linux at the time. I switched to Windows when I realized I couldn’t run anything without an Ethernet cable and my router was upstairs while I was downstairs. Windows works perfectly fine though. I’ve heard stories of Windows not working with more than 4 GPUs. I currently only have 3 so I figured I wouldn’t run into that problem.

Dogecoin Mining Rig Software

I’m currently running cgminer 3.7.2. Use 3.7.2 since it’s the most supported one for Scrypt coins and Dogecoin mining rig. Newer versions have been getting issues with running and tweaking GPU settings for Dogecoins. Running 3.7.2 on your Dogecoin mining rig seems to be the easiest.

I created a .bat file to run cgminer on startup with the following settings:

setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
cd C:namcgminer-3.7.2-windows
del *.bin
cgminer.exe --scrypt -o stratum.fast-pool.com:3004 -u namnomnom.worker1 -p worker1 --auto-fan --temp-target 70 --temp-overheat 80 --temp-cutoff 90 -I 15,14,18 --thread-concurrency 20352,18304,24448 --gpu-engine 1000 --gpu-memclock 1400

My temperature had be rising past 90C under higher intensities. I was finally able to modify the settings to keep it constantly under or around 80C. Anything above 85C can be hazardous to your GPUs longevity.

Install Teamviewer so that you can monitor your Dogecoin mining rig remotely and fore-go having to purchase a monitor. I used another monitor to do all of the setup and then disconnected it and put it back on my daily PC.

Also you may want to uninstall features and disable any unnecessary services to keep your rig running optimally.

Currently my Dogecoin mining rig accumulates around 5000 coins per day.

Dogecoin Mining Rig on Multipools

Edit: I recently joined a Multipool, which automatically mines the most profitable coin and converts it to Bitcoin for you. Doge 1.6 was just released which makes it less profitable for Multipools so you see its USD value going down. This being the case, you may not see any accumulation in Dogecoins at all if it’s not currenly the most profitable coin.

The Multipool I joined was CleverMining. There’s 1% fee and payouts are automatic after a certain threshold or a certain number of days. There’s no registration required. You just use your Bitcoin wallet address as part of your script.

Oh and don’t worry about displaying your address publicly. The worst thing someone can do with your wallet address is send you coins ;P

My new .bat file:

setx GPU_MAX_ALLOC_PERCENT 100
 setx GPU_USE_SYNC_OBJECTS 1
 cd C:namcgminer-3.7.2-windows
 del *.bin
 cgminer.exe -o stratum+tcp://us.clevermining.com:3333 -u 1Bpi1QCzppHm2VnYvBkzKhp4Nh1jTn2QtV -p x --scrypt --auto-fan --temp-target 70 --temp-overheat 80 --temp-cutoff 90 -I 15,14,18 --thread-concurrency 20352,18304,24448 --gpu-engine 1000 --gpu-memclock 1400

Updates! (04-04-2014)

Adding Another GPU to the Dogecoin Mining Rig

So far this update, I’ve added another GPU, running 4 total now in my Dogecoin mining rig. Although the 4th one doesn’t seem to stay as cool as the other. I figured this may need some thermal pasting applied to it when I can get around to it.

 

 

Additionally, I am using a new configuration file and I’m getting the following hashrates:

 

cgminer.conf file:

{
"api-listen" : true,
"intensity" : "19,19,19,14"
"worksize" : "256",
"lookup-gap" : "2",
"thread-concurrency" : "16125",
"gpu-fan" : "20-90",
"gpu-engine" : "1150",
"gpu-memclock" : "1500,1500,1450,1300",
"gpu-memdiff" : "0",
"temp-cutoff" : "90",
"temp-overheat" : "85",
"temp-target" : "65",
"auto-fan" : true,
"expiry" : "120",
"gpu-dyninterval" : "7",
"gpu-platform" : "0",
"gpu-threads" : "1",
"hotplug" : "5",
"log" : "5",
"queue" : "1",
"scan-time" : "30",

}
