if you have a bit coin miner can you please tell me how many g/h m/g or maby even t/h you have. and also is it worth it?. remember im a noob
I have 350 MH/s from 5850, but the GPU is not hashing anymore obviously yeah GPU hashing is not economical anymore, its ASIC's now, still wont get an ROI (return on investment) though, I have 8 GH with erupters running on raspberry pi. |

Welcome, interesting idea, anywhere we can get an update on progress

Right now my cpu utilization stays around 20-28%, That interesting your getting that high of cpu utilization, perhaps your using the older cgminer, i'm using cgminer 3.4.2 and its very stable. I know i had similar problem using older cgminer. what i mean by the load average are the load average numbers that appear after you type the command should have similar result like I have here 07:23:28 up 4 days, 12:02, 2 users, load average: 4.42, 4.65, 4.82 I could have add those wifi and bluetooth, it wouldnt effect the cpu utilization just load average. below is an article that explains in a bit more detail http://blog.scoutapp.com/articles/2009/07/31/understanding-load-averages |

I guess that depend on how many ASIC USB miners you have, I got 24 erupters with 612 (Reject all time) with 597454 (Accepted all time), generally I think rejected share should be around 1-2 percent.

Cool setup, I have about 24 erupters on a single usb port. originally had an edimax wifi and bluetooth dongle, it works fine, but what i found is these usb devices made load increase by 2 which made it slow, After i took the wifi and bluetooth dongle out the load avg came down to 4.5, i'm running latest raspbian with rpi-update firmware. I'm not sure if the MinePeon has the same issue.

Hi Everyone,
I'm a newly register user, i've been reading the forum here and there. I've got a Rpi with 24 usb erupters running raspbian. The interesting part is with running that many erupters on the RPi is loads would got as high as 7.50 which slow the system. However, it still submitted shares just fine and slush is reporting normal ~8GH. What I found is there is a need to remove any usb bluetooth, usb wifi dongles have significantly reduce load avg from 7.5 to 4.8. a big reduction. My setup require latest raspbian with latest hexxeh's rpi-update firmware with cmdline.txt with arguments "dwc_otg.speed=1 smsc95xx.turbo_mode=N " added and modified sysctl.conf line with vm.min_free_kbytes to 16384. Running cgminer 3.4.2. so far it has been running for 80 hours.
Welcome and interesting setup. I dont have so many usb erupters though with latest standard raspbian you can have up to 11 usb erupters on one usb port, given using a usb hub that can power all the erupters with each one taking max of .51A (for variance), without any special changes i mentioned above. Well, i figure if i dont have to keep my desktop on all the time, the savings in electricity each month would be enough to buy an erupter, I used kill a watt and found that my average cost per month for keeping the computer on was around ~28 bucks. However i could buy a laptop but no point since i already have the pi. Also, its more cost effective to use the pi in terms of power. |
