Title: Bitcoin Erupter not hashing properly? Post by: ppumkin on June 25, 2013, 12:47:07 PM I setup p2pool on my ubuntu 12.04LTS x64 machine. Installed cgminer 3.3 and ran it. the newest cgminer is supposed to support the USB mode without any extra configuration.
I have 2 erupters on a powered usb2 hub and 2 running off the motherboard direct. the hashing is just not stable. jumping from 50mh to 300, then getting sick and restarting- there are a ton of rejects. I don't know what is wrong. I have been reading all the posts one after the other and I am stumped. Please can somebody help me. https://i.imgur.com/A9uUCKB.png Title: Re: Bitcoin Erupter not hashing properly? Post by: bobsmith652 on June 25, 2013, 02:14:26 PM How are you supplying the power? What is the rating of the supply?

What is the rating of the supply? 2 are on a powerd hub 2A .. and 2 are on the USB port on the back panel (not front panel) - I put those there to check if any difference.

Those things are already overclocked to a mid level. hence the HW errors every now and again. Those values only showed up for about 30 seconds. It settled down now to the advertised 335mh/s :) Possibly if they get cooled better it would increase it slightly. |
