Title: 2 of 4 Jalapenos throwing alot more HW errors than other two Post by: warhawk187 on June 22, 2013, 10:52:51 PM I have 2 out of my 4 BFL Jalapenos throwing out a significantly higher rate of HW errors in cgminer. Anyone know if this is fixable or if I should send it back for a replacement? Is every HW error also counted as a possibly lost share? Screenshot of cgimner:

Or he could sell me the two lower ones and "watch the HW errors go away".

Or you can donate them to me. :P Title: Re: 2 out of 4 Jalapenos throwing alot more HW errors than other two Post by: warhawk187 on June 23, 2013, 03:18:32 AM Interestingly the one hashing the highest >8Gh/s is throwing a 50% error rate. And the 2nd highest at 7.7Gh/s almost there as well. Whereas the two others going at 7.3Gh/s only have 18 and 33 errors out of 4000 shares Accepted respectively. Doesn't seem to be affecting the shares per minute rate enough to matter. It is just strange that two are producing almost none and the two others are producing over 100x that.

Check the FCC tag on the bottom and see what they're rated at. I'm curious as to how long the queue position for replacements is.

Its just funny seeing 2 throwing <1% HW error rate and the other 2 throwing 50-60% HW error rates. Just wondering if it was going to be an issue, and so far, it has not.
