Title: CGMiner and ZTEX: High HW errors okay? Post by: oxident on August 14, 2012, 09:29:31 PM I've recently started mining with a ZTex 1.15y (quad FPGA) using CGMiner. As far as I can tell everything works fine (2 chips run @ 212MHz, 2 @ 216MHz) but I'm quite unsure about the stats:
After running nearly 4h, each FPGA showed about 4% rejects and three of them had about 150 HW errors. One surprisingly had only 15 errors. I don't know how to deal with these errors because I haven't seen them in the past on my GPU rigs... Is this a normal behavior because the chips are simply regulating their clock speed on high error rates or should I check my setup? Title: Re: CGMiner and ZTEX: High HW errors okay?

I have a modminer quad and running > 10% hw error on bfgminer - is that normal? Title: Re: CGMiner and ZTEX: High HW errors okay? Post by: oxident on October 17, 2012, 06:11:42 AM Someone told me it is. Like I guessed above, the HW error rates are absolutely okay because that's the only way for CGMiner to test if the board can handle the requested speed.
Please correct me if I'm wrong... Title: Re: CGMiner and ZTEX: High HW errors okay? Post by: el_rlee on October 17, 2012, 11:00:38 AM Code: Summary of runtime statistics: 2217/13338=16.6% of my hashing power goes to hardware errors? is that how it should be? |
