have you tried adjusting the clockspeed?
try setting your clock to this --set-device antminer:clock=x0781
Topic: Antminer U2 High Error Rates - Please Help (Read 887 times)
same problem w/ the u2. I get hw errors even when not overclocking. It won't get up to 1.5ghs without overclocking. I'm pretty sure it's just crap-quality hardware. I'm having better luck with a gridseed. You might want to check those out, it's a lil better gh/s for the dollar They can do both sha256 and scrypt, which scrypt coins are a lot more profitable.
bookiwp, I don't understand your post sorry.

Program configuration not to you, your machine configuration and fit the set procedure to configure your, I also get half a month before the promotion, has been often crashes.
I decided to get into mining for a little bit of fun and speculation.
I ordered three Antminer U2s and got them this week.
I'm running Ubuntu, bfgminer, purchased this USB hub: http://www.amazon.com/gp/product/B00ELPSEVW/ref=oh_details_o00_s01_i00?ie=UTF8&psc=1 (probably not the greatest in hindsight, but should be able to run at least three no problem)
and this fan: http://www.amazon.com/gp/product/B003XN24GY/ref=oh_details_o00_s01_i01?ie=UTF8&psc=1
So out of the first three I ordered, one was working great, 0.2% HW errors after about 18 hours, one not so great giving 12% HW error, and one 100% HW errors.
I sent the 100% HW error chip back and ordered two more.
I got my additional two today. One gives me 14% HW error, the other is giving me 70+%!
Am I just getting bad hardware, or is there some setup I'm missing? The chips run pretty cool, barely warm to the touch. I'm not overclocking.
Here is the command I'm using:
Any suggestions?
