is my hardware defective?

Post by Hashing Tortoise » Sun Jan 24, 2016 6:28 am

I have a small asic device (gridseed), Want to get more but according to cgminer, set @ a speed (conservitive) where hardware erros and rejects are rare. Increase in mh/s makes hardware and rejects increase. Tweek higher seems detrinental. The speed (megahash accepted rate) can fluctuate between 6.3m to 4.5m. That's a bit of a range. 4.5ms/s means I should turn it off and 6.3mh/s means I should give it a chance. Did I buy a lemon (?), or is that normal? Thats an wide range. Room temp is 70 F or less. Stock fan, yes I have gotton used to how loud it is, added passive heatsinks, touch anything, it's near room temp or better (to my finger). I could buy more units, but electric/benefit is questionable.
Opinions appreciated...No opinions probably means give up / shutdown.
Not looking for sprikles and ice cream, but real thoughts, including guesses on BTC in the future. True thoughts requested!

You'll find over time that the quality control on these ASICs is amazingly low. I don't know of any other industry where corporations put out products that continually fail and still make money.

When buying hardware, it's always a good idea to assume a 50% failure rate, so multiply the price by 2 when you are trying to figure out whether to mine or not. Cloud mining services take this risk of hardware failure off your back, but they have their own problems.
