Antminer U1 help

post #1 of 8
Thread Starter 
Right now I'm running the Antminer U1 with CGminer 3.9.0 and it says I'm only running at .566 Gh/s. Now I am not a math major...but .5 doesn't seem like 1.6 Gh/s...I need help, any suggestions? I am a bit out of my element, any idea's on why it's going so slow?

Which launch options?

Are you using the 'special' cgminer (although I'm not sure specifically what would be different) ?

Did you solve this?

If not post your options. Lets see what you setup.

I did on my desktop I just had to install a different version of CGMiner (3.8.5).
I now have to get it set up on my raspberry pi...wish me luck...I have had none so far!

I had the same issue with the U1 being slow on the raspberry pi. My solution was to use a powered USB hub rather than plugging directly into the Pi. I've been running 2.0Gh/s for 10 days straight now.

I'm now using Minepeon and looking stable at the 24 hour mark...But why would I be saying this on the OCN forums if I am not going to OC it...Time to get to work (I got this great external fan I'm using for airflow so i should be able to hit 2.0 Ghz easy, and stable, maybe beyond...definitely beyond...)

NOTE: When I get to clock speed (overclocking) bench-marking I'm going to do it on a different thread I will eventually link to here:

I grinded down the screws that were protruding out the top of the stock heatsink and strapped an old CPU heatsink to it with some thermal grease. I run 2.0 all the time, if I try to bump it up to 2.2 I end up with 1.3-1.5 hash rate, probably due to errors. Anyway if you are brave the manual shows you which pins can be shorted to change the supply voltage, but I'm not that brave yet. Maybe when the difficulty goes up and it has a lower rate of return I'll try it.

Rip5, first off I hope I'm not the first to say: WELCOME TO OCN!

Using a Antminer U1 with BFGMiner (CGMiner will work fine as well) at the frequency speed of 881 (Mhz) I got a 1.88 GHs average on my PC, I'm slowly upping the core clock from stock again on the raspberry pi (hopefully getting to that on Monday). I will slow and steady (a.k.a. carefully: something new to overclocking (I kid, I kid)) raise my core clock and post ALL of the meaningful and helpful stats/tips I find from this project. So yeah! On Monday I will hopefully get the new thread up and running, I'll link to it then, and I recommend following it because "What could go wrong?" (everything)
