Is it possible to overclock antminers separately with different oc?  I have one antminer I would like to oc to 0881 and the other one to 0981?

One of my antminer has 14% HW and the other one 0% HW with 0981 oc.

Yes you can. First run bfgminer with -d? -S antminer:all to list the devices and their paths:

Code:

bfgminer -d? -S antminer:all [2014-01-12 13:16:59] Started bfgminer 3.9.0
 [2014-01-12 13:17:00] Devices detected:
 [2014-01-12 13:17:00]  Device (driver=antminer; procs=1; path=/dev/cu.SLAB_USBtoUART)
1 devices listed

Then use the path displayed (above) in the --set-device argument:

Code:

bfgminer -S antminer:all --set-device antminer@/dev/cu.SLAB_USBtoUART:clock=x0881

The format is now:

Code:

--set-device antminer:clock=x0981

Thank you!

I am using this (https://www.dropbox.com/s/z29x4n6ng510joi/bfgminer-npw-antminer.7z) in Win7x64 with the parameter "--set-device antminer:freq=0981" It starts up ok, finds the antminer but reports that
"AMU 0: Applying rule antminer:freq=0981: Unknown option:freq" and then starts hashing at the standard speed. Why? Supposedly overclocking is working? Am I doing something wrong?

Full start parameter is "bfgminer.exe -S antminer:all -o pooladdress:port -u XXX -p XXX --set-device antminer:freq=0981"

The format is now:

Code:

--set-device antminer:clock=x0981

I have just tried this update.
My hash speed has gone up from 2.05 to .............................2.05
If I go any higher I have massive HW errors

From what I understand, depending on the unit you can't over-clock it higher without giving it more power.

One of the forum pages has some more info on changing the power resistors, to improve the overclocking.
I will stick at this level for now, 2.05Gh at the 5 second interval and 1.98Gh average at the pool.
Not bad at all for the price and power consumption. 1.28watts/Gh on 11 sticks.
Blue/RedFury are showing at 1.23watts/Gh but cost 3 or 4 times more to buy.
(starting to become a power tart)

You know, you are really good and fast! Thank you very much, it works perfectly.

So, if I download the bfgminer-npw-antminer from the link posted previously ... I just have to run that by itself for now correct?

In other words, I can't drop those files into the 3.9.0 directory.

[twib2]

Hi nwoolls,

I've got the newest version of your 3.9.0 build for the antminers, and I do all the steps for linux - autogen.sh, configure, make, and antminer shows up on the -h switch.  However, even though my ants work with the bitmain cgminer 3.8.5, and with fractalbc's cgminer 3.9.0, I can't get your bfgminer to recognize them.  bfgminer -d? -S antminer:all shows no devices, yet they're there just fine in lsusb, and of course for the two cgminers.  I don't notice any errors during compilation, configure shows it as enabled for the antminer, and I'm using the correct binary - even called it by the full path just to be sure.

FWIW, this machine is Edubuntu 13.10, 64 bit version.

Any idea what could be going wrong?
Thanks,
- Tye

Running the new antminer version of bfgminer with the antminer overclocked and two usb block erupters. Look at the Hardware Error Rate:

https://dl.dropboxusercontent.com/u/15558107/Pictures/bfgminer_antminer_HW.png

On bfgminer 3.9.0, I was only receiving errors on the antminer because it didn't realize what it was.  The ASIC Block Erupters never really threw an error.

Running the new antminer version of bfgminer with the antminer overclocked and two usb block erupters. Look at the Hardware Error Rate:

They're all less than 1%. You are doing good.

Yup ... should have looked before I posted.  I overlooked the "/" for some reason.

Greetings,

I'm running a cube using the bfgminer proxy but the longpoll is showing as inactive & I'm only getting 67% efficiency as well as 34% rejects - can you tell me the command to enable longpolling as I can't find it in the readme......thanks anyone.

Peace.

Peace.  

I had this discussion with Luke-Jr about a month ago.  There is no Longpoll support, but he said he'd look in to adding it.  

I found that running bfgminer on Linux helped a lot - I'm getting a solid 38GH out of my Cube connected to bfgminer on a Celeron 847 PC running Debian Wheezy. 
When I point the Cube to the Pi running MinePeon and bfgminer, the Pi's CPU is running flat out and efficiency goes to crap.  It runs OK on the BeagleBone Black running Debian, too (dual 1GHz ARMv7).  The same Celeron machine running a stripped down Windows 7 install is also inefficient.

Well bugger me sideways, that's several hours wasted then, thanks HelldiverUK. I'm running Xubuntu 12.04 but was unable to get slush's proxy working with my cube & p2pool for some reason, it just wouldn't connect, but works fine on other pools - any pointers or ideas my man?

Peace.

Greetings. I too have an antminer that is throwing a high rate of errors and I'm having problems with downclocking a single antminer. When I run the device list, I see all of them listed as \\.\COM(NUM). of course this doesn't help when you have more than one as you don't know which is which. but i deduced it was COM54. when I run bfgminer with the --set-device for that path, it seems a random antminer will be downclocked. never seems to be the same one nor the problem antminer.

any suggestions?

The U1 may support sending it an identify command so that its LED lights up. I'll have to look into it.

I'd try Debian or Arch.  

Ubuntu seems to be bugged or just broken in a lot of stuff that isn't desktop related.  I never had any luck getting mining stuff working properly on Ubuntu, yet everything worked perfectly first time on Debian.  I've had p2pool working on Debian, I have slush's proxy as backup to BFG running, and I run bfgminer on one Debian machine and cgminer on the other - both compiled and worked perfectly first time, and I'm a bit of a linux noob.

Neil (mineforeman) said he'd recommend Arch over Ubuntu-based OS, too.

I had slush proxy running previously on 12.04 & p2pool before I switched my node off - but after switching it back on again I can't for the life of me remember how I done it....   This bfg proxy is losing me 30+%!

HellDiver, I don't suppose you remember the slush startup command line for p2pool can you? I can't find an example anywhere my man. I seem to remember having to change something on the cube webface too - but my brain fade has got the better of me today......

If you do a mining_proxy.py --help that'll bring up the commands available. 

I'm using screen -dmS proxy mining_proxy.py -o <pool host IP> -p <pool port> -gp <getwork port for your Cube> -cu <your payout address> -cp x -q

That spawns the proxy on it's own screen, and allows your miners to connect with any username, and the proxy will submit the shares to your p2pool node with your payout address.  You'll want to change the -gp port to something different to p2pool's port (say 8330).

Yeah, that's what I tried earlier, plus a number of variations too - I just can't get it to click, sure it's something stupid I'm missing. Did you make any changes to the cube webface at all?

Thanks for the ideas by the way, it's appreciated - I hate seeing a third of my work going to waste with this proxy.....
