Bitmain AntMiner U1 Tips & Tricks

[philipma1957]

Nothing goes to waste in my mining rig tangle.

bitmaintech cgminer, built as per cs2000's post on a fresh install of ubuntu desktop 32-bit, cgminer args include –bmsc-freq 0981
(–bmsc-freq A081 gave me nonce timeouts. Which is only funny in british english.)

The asus eee netbook istelf is also cpumining at a hilarious 0.69 khash/s but meh the machine is on and sucking negligible power, so why not.

I like the fan. it will keep those sticks cool.  I  have an asus eee notebook  a 1215 I think.  I should dig it up  and see what I can get it to do.

My antminers arrived but I was still a hub short to add them to my raspberry pis, so broken screen netbook seemed the obvious choice!

I had to install fresh linux to get it to compile nicely, which was fast on the SSD. I tried to have the patience to install to an SD card but nope. Ubuntu desktop almost fills the 4GB SSD but miners are tiny and I should've used Ubuntu server anyway. Those L-shaped USB elbows are the crazy useful too, since you can bend them the way you wouldn't dare bend a miner to get two in neighbouring USB ports. I think an eee might take an unpowered hub, too.

It's kind of hilarious seeing miner output fullscreen in a cracked LCD. It feels very postapocalyptic.

How comes  you have so low HW rate?
  My ANTIMNERS are running at 2GHS @ diff 8. and i have about 150 HW to 1000 Accepted shares.
 What do i do wrong?
The  Antminers are  powered from SUB3:0 hub with 4 A output.
The hub is connected to the USB2.0 port on my PC, but i assume that  there is not so much data to transfer, so speed shouldn't be a problem.
 Miners are pretty well cooled to  about 35 C°
 What am i missing?

I have 30 u1 oc @ 2GH/s :
one has a lot of HW err ( 13 %)
bot others have less than 1% HW err


running on powered hub with 80 plus gold PSU

Hm,
 I also had one  faulty Antminer with high  HW Rate, it died today:(
It starts at 2 GHS as intended, but  after 2-3 min  it slows down to about 200 MHS. Most propably it is some  physical damage due to the  thermal expansion.
Lets see if my warranty will work in this case ( purchased on ebay)

how did you OC with bfgminer? did you solder resistors? thanks!

Funny that, I was just coming here to ask that very same question.



There's plenty of power on an Antec USB hub, and the .bat:

Code:

C:\Users\M\Downloads\CTB\Antminerminer\cgminer.exe -o stratum+tcp://stratum.mining.eligius.st:3334 -u <"Shut up, Flanders."> -p xxx --bmsc-options 115200:20 --bmsc-freq 0981

They're plenty cool, is there anything I can do, or, do I ~need~ to do anything?

Thoughts, anyone?

I gave up on the bitmaintech branch because of some of the other changes they made to cgminer and pulled the latest ckolivas 3.9.0 repository, merged the bmsc driver and posted it to https://github.com/fractalbc/cgminer.git

This is very interesting.

Can you just clarify what you did when you "merged the bmsc driver"

The bitmain version of cgminer is terribly unstable and doesn't work with the adafruit piminer lcd scripts because of the API changes Bitmain have made so id be keen to replicate what you have done.

I cloned the official cgminer repository and added the bmsc driver to it without the other cruft from the bitmaintech branch.  It might be worth testing your piminer with that branch to see if it works.

As a side note I tested a blue fury and it crashed after a couple of hours.  This happened twice.  I will test the blue fury by itself on a stock 3.9.0 build to figure out if it is something I did or not.

I've got two Antminers U1 running on an old Linksys Nslu2 NAS. Tested with 200 gh/s. The picture shows my first configuration.

So, will your ~second~ configuration be to reverse the two devices?   8^]

Got mine up and running with bfgminer on a RPi thanks to you guys!

Overclocking in bfgminer would be awesome

Thanks again,

Tek

You've just reminded me that I've got a D-Link DNS-320 hiding under my desk... Half tempted to try getting some use out of that!

This is the latest Nslu2 set. 2x antminer, Debian Weezy, nwoolls bfgminer and some old hardware.
Thanks again for the support.

Brilliant, thanks.

Have done this through the evening and am having at about 1ghs faster with your build. Plus, as a bonus, the LCD works again due to the api.c file being standard. Im still testing for stability obviously but im just running with the 3 ants in here, left my BE's out for now.

[lajz99]

Can someone post an rPi image with minepeon for this?

Will reward .01 if it works.

[nwoolls]

Got mine up and running with bfgminer on a RPi thanks to you guys!

Overclocking in bfgminer would be awesome

Check the repo in an hour or so. Device detection and overclocking are done. You can run them side-by-side with Erupters and all. Just tweaking things now.

How do I build for antminer nwoolls?
I cloned the repo and built but it doesn't detect my devices. At the end of the ./configure it didn't list the antminer there at all. Still didn't detect my ants.

[elpres]

Interestingly fractal's cgminer crashed on the pi after about 1-2 hours. It runs fine on ubuntu for about a day so far.

Haven't been able to get bfgminer to detect my ants.

I had to find some time to solder up a new power plug to give that silly power brick a rest.  I now have 7 U1's and 9 erupters all powered by a 80+gold rated supply seen in the background.



Works pretty well



Everything is in the config file.  Command line is a simple

screen -fa -d -m -S miner ./cgminer -c ~/btcguild.conf

where the config file contains

Code:

{
"pools" : [
 ... my pool info
]
,
"api-listen" : true,
"api-mcast-port" : "4028",
"api-network" : true,
"api-port" : "4028",
"expiry" : "30",
"hotplug" : "5",
"log" : "5",
"no-pool-disable" : true,
"no-submit-stale" : true,
"queue" : "1",
"scan-time" : "15",
"shares" : "0",
"kernel-path" : "/usr/local/bin",
"bmsc-options" : "115200:20",
"bmsc-freq" : "0981",
"icarus-options" : "115200:1:1",
"icarus-timing" : "3.0=100"
}

I still haven't had time to find out what's wrong with the blue fury.

Make sure you run it as:

./bfgminer -S antminer:all

Wow, you rock! Thanks! Will def. check the repo after work today.

Are you saying that I will be able to run my Erupters, Blue Furies and the U1s off one single instance of bfgminer?    

Please give advice how to enable overclocking when you are finished.

One last noob question: Do I have to rebuild bfgminer or just perform a "git pull"? Much to learn I have.

Thanks again!
