What's the price? He said, "pay for breakfast", which I did. My friend isn't technically inclined and asked me if I wanted it. His sonĭiscarded it in my friends garage. He told me his son bought an AntMiner U3 (the silver domed one) and couldn't get it working. So there I was sitting having breakfast with a neighbor/friend of mine about a month ago, and the conversation turned toĬrypto-mining. You should see the 1.6 Gh/s ASIC WUs download. Then go back and update BU in Boinc Manager. Then go to the your BU account and under the preferences, select the 1.6 Gh/s apps for the campaigns you want to support. If you do overclock, I'd recommend using a powered USB hub and put a fan on the U2 to keep it cool. There's a section for each of the campaign 1.6 Gh/s apps. If you want to overclock your U2, add this to your BU app_config.xml. If you do, I think you also have to upgrade BOINC to 7.4.22 or higher.Īdd this to your cc_config.xml file, where the count is the number of U2s you have. 05 of a CPU core, not much.Īfter re-thinking, if you only have one U2 and don't want to overclock, you might not need all the stuff below. I think I'm averaging about 1.5 million per day per U2 but they are overclocked to 2.0 Gh/s. Now maybe 1 blade per day needs to be reset. When running 4 r3 blades per WU, I'd have a blade lock up at least every few hours, sometimes sooner. I'll do another post about how I got the latest version of BOINC running on the Rpi.Īlso, running multiple WU with 1 ASIC per WU has really helped with the rockminer r3/rbox stability. (This example will run 3 concurrent WU with 2 ASICs per WU).ġ) Make sure your app_config.xml limits the max_concurrent WU for the project or appĢ) Make sure your app_config.xml has the correct option, for each BU app, to use the desired number of ASICs per WU. If you want to run multiple WUs using only 1 ASIC per WU, then.ġ) Make sure you are running the latest stable version of BOINCĢ) Make sure you have you have this section in your cc_config.xml file with the count set to the correct number of ASICs.ģ) Make sure your app_config.xml is not limiting the max_concurrent for the project or app Here is how you can control how many concurrent WUs you run and how many ASICs to use per WU. That also means only 1 ASIC will be used by the WU. I should have added this info before, so here it is.Ī recent change in the BU app now uses a default command line option -usb:1 which causes the cgminer program to only use 1 ASIC.
