Bitmain AntMiner U1 Tips & Tricks

[BRADLEYPLOOF]

im getting  unexpected command argument when runing  .bat file, what am i doing wrong

bfgminer.exe –set-device antminer:clock=x0981 -o stratum+tcp//us1.ghash.io:3333 -u 1122.ghash -p 123 -S antminer:all

bfgminer.exe –set-device antminer:clock=x0981 -o us1.ghash.io:3333 -u 1122.ghash -p 123 -S antminer:all

i uses these so far and btcguild, i dont think its a url  ,user ,password issue.

use two dashes for set-device.  it should look like --set-device antminer:clock=x0981

thanks man , im really bad with tech stuff. does the overclockin run better on bfg 3.10 or the nwo 3.9

I like BFG 3.10.  Seems to work really well for me.  Plus Luke-Jr is pretty quick at answering questions that arise when using his software...

add a timeout so they don't run at the same time if that's what your tryin to do but the top line will grab all the miners im thinkin

bfgminer.exe –set-device antminer:clock=x0981 -o stratum+tcp//us1.ghash.io:3333 -u 1122.ghash -p 123 -S antminer:all
timeout 5
bfgminer.exe –set-device antminer:clock=x0981 -o us1.ghash.io:3333 -u 1122.ghash -p 123 -S antminer:all

Is there any way to get the correct clock speeds in cgminer instead of the block erupter speeds? I have a large config file with many pools and don't feel like making that all over again

Guys, I have a strange Problem. Hope someone is able to help me. 0.05BTC bounty for getting my miners to atleast 2,6 Ghash each

I got 16 Antminer U1. All are running at 1,088 V. I have a 49 Port USB Hub and a 450W PSU exclusively for those 16 U1. I have additional coolers attached and a fan blowing cool air. The Miners get definitely not too warm.

I tried Bitmain´s Cgminer, different BFGminer version on Windows, Minepeon and Raspcontrol. Cgminer gave me too much errors and for BFGminer I have the following Problem:

While I should be able to get 48 or atleast 44,8 Ghash out of the 16 U1, I get far less. Recently did some testing with BFGminer 3.10 and Raspcontrol

At 4D81 I get 6 Ghash
At 4C81  I get  10 Ghash
At 0B81  I get  12 Ghash
At 0A81  I get  15 Ghash
At 0981  I get  14 Ghash
At 0781  I get 10 Ghash

The Problem here is, that most Miners run somewhere under 500 Mhash. No Hardware Errors. Those U1 who do more Ghash are getting warmer then those who only do some Mhash. From test to test the variance is very big.

Currently they run with 4C81 under BFGminer 3.9.0 and Minepeon with 25Ghash. For some reason the hashrates with bfgminer 3.9.0 are similar among all sticks. The best result I got so far was about 30Ghash (also BFGminer 3.9.0 and Minepeon). The funny thing is, that I didn't give any frequenzy to BFGminer in this test so that the Miner should have run with 1,6Ghash. For some reasen they did nearly 2Ghash. This was absolut stable (ran for <24 hours). Again: I do not get any errors (or very very few on some sticks <.1) beyond 4E81.

Sorry for the bad english  

Thanks

Use bfgminer 3.10  Works the best! Also, to bump each of those past 2.2 GH/s each, you'll need to solder in a 10k and 2.49k or 3.74k 603 type resistors in the R1 and R2 slots as seen here in the AntMiner U1 User Guide: https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&ved=0CCYQFjAA&url=https%3A%2F%2Fraw2.github.com%2FAntMiner%2FAntGen1%2Fmaster%2Fmanual%2FAntMiner-U1%2520user%2520guide.pdf&ei=Ntz6UqaUAsH30gGloIHwCQ&usg=AFQjCNHyBa6WMwUpIpV_aHdL27m5KxKn1g&bvm=bv.61190604,d.dmQ

The power supply should be adequate so no problems there.  There is definitely going to be soldering involved though so you'll need a very fine soldering iron tip, a very powerful magnifying glass, and some very delicate tweezers...

[muto]

Unfortunatly for me 3.10.0 is not working as "good" as 3.9.0. Can´t imagine why

I (it was not me but MansenP who has alredy soltered several U1s successfully) already soldered in 10k and 3,6k resistors. Because of that I wrote that de U1s are running at 1,088V. Should be enough for 3Ghash. But I do no think the problem is there. Even 2,2 Ghash is  not working. And I should get hardware errors when my voltage whould be too low.

[Dunkelheit667]

muto, do you know, how many A your 450W PSU can deliver on the 5V rail? With this mod, each U1 will draw at least 1A for 2.6 GHash/s as MansenP measured here.

This means your PSU should deliver at least 16A on the 5V rail, would personally feel comfortable with 20A.

Would test again with 10 Antminer's plugged into the Hub and check if they are running stable or not. In case they do, plug in additional Ants one by one, to check the critical mass for your PSU.

Just a thought.

Do You use --icarus-options 115200:2:2 switch in Your start line?

hi to all,

maybe someone already had post about this, but I need to know how many u1 I can connect to a raspberry:
my plan is to connect 2 Dlink DUB-H7 7-Port USB 2 Hub to the ports of the raspberry. How many u1 I can connect to each hub? 1 port will be for the fan, anyway, and I know one of the 7 ports is not usable... so 10 u1 is ok for a single raspberry? I'm worrying about the bandwidth mainly

what if I want to overclock @ 2,2Gh/s? will be a problem?

I have 8 connected to mine, along with a 120mm fan on a 10 port hub. It's all running happily from a 5A/5V power supply and uses 26W at the plug. I've modded the hub so the Pi takes its power from the hub to reduce the cable clutter.

[Mudbankkeith]

using BFGminer 3.10.0
this .bat will get you to 2.2Gh                         after that you need a soldering kit.

By the way, the first official cgminer fully supporting these devices is 3.12.3, and only one command line based on frequency is required instead of the numerous command line options all other software seemed to copy from each other:
--anu-freq 275
will get you 2.2GH. Most will run reliably with much lower hardware error rates at 250 but also lower hashrates.

great! overclocked? can I ask what usb hub you are using?

I have that same hub with a 8A psu.
What mod have you done? Soldered a cable in the +5V rail?
I have 4 Ants @ 0A81, 2 BE OC'd @ 447 and one normal BE in that hub.
I have other hub I can't plug in it, I had to plug it on the computer, since whenever I plug one more BE, 2 or 3 BE go zombie after sometime. Even the Ants get wrong clocks, so I've wondered if it has anything to be with the mod.

There is a diode which stops power going the wrong way up the USB host cable, I just soldered in a wire to bypass that so that the Pi can draw its power from the host cable. It isn't necessary if you power the Pi from another plug, but I wanted to keep the rig as neet as possible.

the +5v from the power section and +5 from the usb section are wired togheter, but if you get power from the usb, you are bypassing all the buffer/filter/protection section on the input part of the raspberry... or I lost something? how long have you modified the hub in this way?
