Rasperry Pi - High Hardware Errors

[Raptor2213]

Been having some trouble with my Pi, and wanted to ask about it. 

I'm running a Pi B with an old D-Link 7-port hub. 
I'm mining with 3 Gridseed 5-chip miners.

I've used:
 - MinePeon with BFGminer 3.99
 - Scrypta with BFGminer 3.99
 - StarMiner with CGminer 4.3.0
All 3 return 5-10% HW errors.

If I plug the same hub in to my Win7 PC and run from BFGminer 3.99 on it with the same settings, I get 0% HW.


Any ideas?

I assume that you've checked the 12 volt power to your Gridseeds?

Also, you can try Minera with Sandor111's cpuminer in auto tune mode. What it does is try to find the optimal per chip frequency for the GridSeeds.

Here's some threads that might be helpful:

I have not checked the power, but it works fine with the same power connector.  I currently have 2 undervolted Antminer S1s, and the 3 Gridseeds on one EVGA 1000W P2, so I doubt power is an issue.

I would suggest trying Minera, from my experience it is the most stable front end for Gridseed mining.
