190 GPUs

So your farm is around 150Mhs ?? Where did you place your farm?? I don't find any place in western world with cheap electricity, so I plan to extend my farm to Asia (China or Vietnam). But maintain it would be a nightmare so I still consider. Could you share some tips how you maintain your super big farm??

More like 120 to 125. We don't live in a perfect world. I'm incorporated and I pay. 07 cents per kw. There are a lot of places in the US are there is cheap electricity. Just have to look.

I programmed my own miner monitoring application that controls the cards and redistributes them to different coin networks and restarts the gpus.

The biggest thing you should worry about is airflow. Hire an HVAC specialist to do it right.

The best price I paid in Europe right now is 0.15 USD / kW (incorporated too. The base price is around 0.07 USD too but one hell of tax here in West Europe) . And price for electronic equipment is a lot higher than in US. It made me sometimes to think that USA is the true paradise for technology Cheesy

I have a pretty big industrial warehouse here so I will split my next rigs for better airflow. Thanks for your tips.

Uhm you mean you have completely rewritten miner from scratch or you wrote your monitor app which uses cgminer api to check and control your rigs?? Or you forked cgminer and rewrite the interface for your need ?
It's pretty good idea. I don't think it is very hard but it still requires time. Could you tell how long did you take to write your app ??

Thanks for answering

Hey no problem, its about sharing knowledge. I'm not as cutthroat about mining like others here. US is not necessarily a paradise. You have to look long and hard. I went through about a hundred townships in my region to find the one with the lowest cost. It was a geothermal plant so is low cost. Plus incorporating they exclude delivery charges. Yes EU is terrible for taxes.

I did not rewrite cgminer. I wrote a monitoring app that is installed on and monitors each rig. It reports back to a server that has a rules engine that defines how I want the network to operate. The head server commands each rig to mange gpu settings, restart even change pools. It also distributes rigs to different pools mining the same coin so distributed hashing. Its proprietary to the corporation.

I wrote the app part time so about 20-30 hours a week and it took 2 months. Then on going upgrades and improvements, so maybe 500 hours or more. I have had offers to license it, but I have not taken any yet.
