Hello, Pretty new to the mining thing here...
I currently have 5 ASIC USB sticks spread across a usb 2.0 hub, and 2 units directly connected to the machine. Having done research on these before purchase, they also have a small heatsink over the ASIC chip itself. Backed by a 120mm server (high RPM) fan less than an inch away.
I had gotten #5 in the mail today and went to work, once I was done messing with the hub and connectivity issues, I am up and running. However, I notice I seem to catch a few HW errors than I should, and probably more importantly, one of the USB miners is accepting shares at a lower rate. Example being :
ICA0: A:387 R:10 HW: 8 ICA1: A:385 R:5 HW: 4 ICA2: A: 80 R:4 HW: 3
etc...
According to CGminer 3.1.1, ICA2 is hashing at the targeted/advertised rate, though the accepted share is so low. Sadly, I was not paying close enough attention while mining with the four to know if this is an ongoing issue or not.
It seems to me I am having a high number of HW errors given that such a high flow fan and added heatsinks are onboard. Is it possible I have bad USB sticks, or is this more simple and along the lines of a USB hub being the cause?
Any help/pointers etc is much appreciated! I can provide Screenshots or anything if needed.
Thank you
System: AMD FX6100 Win7 64bit 990FX chipset
