Title: How do I reduce hardware errors with my ASIC USB miners? Post by: NullVoxPopuli on October 29, 2013, 01:33:52 PM See my console below, it is showing a pretty good hash rate (in GH/s, rather than MH/s)
On coinex, it says I'm getting from 400 to 800MH/s... but cgminer says I'm getting 4.6 GH/s. I've tried multiple pools, and the speed discrepancy appears to be the same for every pool. Code: cgminer version 3.6.3 - Started: [2013-10-25 17:08:01] what do I do? Title: Re: How do I reduce hardware errors with my ASIC USB miners?

Get a better USB hub, there's a thread out there listing known good ones. Either that or just buy a dlink dub-h7. Title: Re: How do I reduce hardware errors with my ASIC USB miners? Post by: NullVoxPopuli on October 29, 2013, 02:37:15 PM .

This is the hub I'm using: http://www.amazon.com/gp/product/B0051PGX2I/ref=oh_details_o01_s00_i00?ie=UTF8&psc=1 It has external power. What about a hub makes it good or not? Title: Re: How do I reduce hardware errors with my ASIC USB miners? Post by: pontiacg5 on October 29, 2013, 02:59:00 PM I have that exact hub, it only has a 2A power supply. Each block eruptor uses .5A, so that hub can only theoretically run 4 miners.
It's a steaming pile of crap though and won't even run two miners. You need a new USB hub. Search USB hub for miners on this forum and I guarantee you will find the thread with lists of good hubs. |
