OLD: BFGMiner 3.10.0: modular ASIC+FPGA, GBT+Strtm, RPC, Mac/Lnx/W64, AntU1, DRB

[Luke-Jr]

I get a little better performance on my GPU miners running scrypt with cgminer than I could tweak out with bfgminer. 

When I switched to BFGminer, I also noted the big performance differences, but then found I was able to get the same performance once I used optimized .bin files again, as I was using in CGminer. I know NWoolls has mentioned this to Luke, and I'm able to reproduce it on all 45 mining rigs.

Where did the optimised .bin files come from?

[nwoolls]

Where did the optimised .bin files come from?

The Litecoin forums. I have some ideas on these, but so far they don't actually improve performance with my own GPUs.

The idea is this: take the existing .cl files, and then take the known GPU models you are working with. Then remove all of the branching logic in the .cl files and create files that are specifically for your GPU, specifically for the thread-concurrency you will be providing, specific to the work-size, etc.

My thoughts were that it should really be trivial to add an optional process that does this as a pre-processor to the actual .cl to .bin compilation, but again so far I have not been able to reproduce the improvements (much less had the time to implement this).

Thoughts?

If you "HAVE" to use CGminer,( LOL ) then you need to specify each type of miner with the required arguments.

Why's it LOL?     I HAVE to run cgminer because bfgminer doesn't support my Bitburner Fury.  That one board makes up nearly 1/3 of my hashing speed, but I can't run it off bfgminer.  So, I run cgminer off a BeagleBone Black, and the other 100GH runs off a PC running bfgminer (I only run a PC because my hubs are USB3 and none of my ARM machines play happily with the USB3 hub).

What do the three speeds for each device mean, relative to each other? I just updated to 3.10.0, and plugged in the antminers that arrived today, and I see the third speed reported as 2GH, but the other numbers are half that. Is this normal?

Hiya mate,

I see that you have the antminer working on your bfgminer 3.10.

I cannot get the S All option to run -- in fact bfg 3.10 cannot find my 2 Antminer U1 units.

My OS is Win Vista.

Should I add the S and Com port in bfg 3.10?

What should I add to this line to make the antminer run with 0781 freq option:?

bfgminer.exe -o pool.emercoin.com:3333 -u xxxxxx.xxxx -p myworker -S \\.\COM3 -S \\.\COM4

At the moment I am using cgminer 3.10 and can only get hash rates of approx. 450 Mh/s  

Thanks in advance for any help.

[TheGreatWhatsIt]

The only way I was able to get my antminer U1 devices to work was to go to:

https://github.com/antminer/antgen1/tree/master/cgminer

and follow the directions precisely. the "--bmsc" portions of the command line tell CGMiner how to talk to the Antminers, and I'm not sure those "--bmsc" options are compiled in every build or the default build. I haven't really experimented much after I got everything working. I figured if it is broke, don't fix it.

So on one Win 8.1 box I have Easyminer running my BFL SC 50 Gh/s with the latest CGMiner, and an instance of CGminer 3.8.6 from that github address running my 4 antminers overclocked at 1.9GH/s.

[marcocoin]

Hiya mate.

Thnks for your post.

I think I will try CGminer 3.8.6 tyo see if ithat version will accept the --bmsc options.

Did you have to give the COM port numbers?

If possible can you post your antminer run command syntax?

Cheers

do like this -S antminer:\\.\COM3 -S antminer:\\.\COM4

[marcocoin]

WWWIN -- thanks for your reply.

I will try that.

Cheers

[TheGreatWhatsIt]

cgminer.exe --bmsc-options 115200:20 -o stratum+tcp://stratum.mining.eligius.st:3334 -u walletid -p x --bmsc-freq 0881

use freq 0781 as the default then try 0881/0981/0B81

Like I say, once I got this working the way i wanted I didn't attempt another method, and I'm sure if Luke Jr. says BFGMiner works with antminers, then you can get it to work.

[wwwin]

WWWIN -- thanks for your reply.

I will try that.

Cheers

but you have to uninstall Zadig driver for the antminer to use with BFG, the com port should show this Silicon Labs cp210x USB to UART Brigde, not the Zadig USB driver that you installed to use cgminer.

[marcocoin]

WWWIN

I will remember that.

I am using zadig for the cgminer 3.10, but that program refuses to accept the bmsc options as adding it to the command line makes the command window to appear for a second and disappear.

Perhaps that was the problem.

I will try the BFGminer 3.10 with the Silicon Labs cp210x USB to UART Brigde drivers first and work my way down the versions.

Thanks

[TheGreatWhatsIt]

I'm 99% sure the antminer bmsc options only work with the CGminer build from that address in my first reply.

[marcocoin]

Cheers.

I will download it and try it.

Thnks

So, has anyone ben able to use BFGminer 3.10 in OpenWRT  to mine with a antminer S1?  I have installed to into Openwrt and can run it but

It does not detect any devices.  Bitmain has not released official firmware for this that includes BFGminer.  Their official firmware includes CGminer

3.8.5-1.

[Luke-Jr]

So, has anyone ben able to use BFGminer 3.10 in OpenWRT  to mine with a antminer S1?

Only U1 is supported by 3.10, sorry.
S1 support is on our todo list, though!

Thanks for quick reply.  Nice to see this will become available later.

Thanks Luke, this 3.10.0 works pretty easy for a newb.

BG was a long drawn out fail on windows here. (those weird drivers and the zdiag thing of plugin and pullin was to wear out my ports fast.) Bitminter Java client crapped out on me after I said it was working,, hrs later Ran the ant for a week or more just slow, and alot false errors. That is what I get for opening my mouth.
haha.

rem # bfgminer  -o stratum+tcp://mint.bitminter.com:3333 -u freddyfarnsworth.1 -p x -S antminer:\\.\COM5  --set-device antiminer:clock=x0881

bfgminer.exe -o stratum+tcp://mint.bitminter.com:3333 -u freddyfarnsworth_1 -p x -S antminer:all -S all --set-device antminer:clock=x0881

Top one was a fail I commented it out and added line 2

Line 2 is working, any changes needed ?

Also wat is the "pool 0 is hiding block contents from us ? 
I got that on the top one not the working one ? Bad Login ?

[BillTech]

hi all new forum user here waving a hand
hi just took up the hobby
and I have a question
ok I currently have 4 ants
I want to run 3 on one pool one on another pool
the way I set up my command it seems to work right
if I start one after the other is this the proper most efficient way thx

cd I:\Antminer.U1\bfgminer-3.10.0-win64
TIMEOUT 5
start /min "Bitcoin" "I:\Antminer.U1\bfgminer-3.10.0-win64\bfgminer.exe" --set-device antminer:clock=x0981 -o url:port -O user:pass -S \\.\COM26 -S \\.\COM27 -S \\.\COM28
TIMEOUT 5
start /min "PPC" "I:\Antminer.U1\bfgminer-3.10.0-win64\bfgminer.exe" --set-device antminer:clock=x0981 -o url:port -O user:pass -S \\.\COM29

thanks

2. Is it normal that they show as Icarus?

Yes, you need to pass in -S erupter:all in order to have them detected as a Block Erupter

Must I do it or may I leave them being recognised as Icarus? Does it change anything from practical point of view?

3. BFGminer doesn't show me the temperature, what to do to have it shown?

Block Erupters do not report their temperature.

Ok... I have a radiator and it is a bit warm in the place it touches erupters (not hot) - I hope it's sufficient cooling?

erupter or icarus its only a name at this level.    If you have any other devices then you can name them, but then you need      -S erupter all -S otherdevice all

A small USB fan for some cooling is helpful.

Hey, I have the problem with 2 erupters on a usb hub. I've put a command like before and the bfgminer could not see them, but tried a few times, and it started to see both. BUT one of them began to make a lot of HW - I mean one of them was working OK, getting accepts and so on, but the second one gets 95% HWs. I've tried changing their physical positions in the hub, but it didn't help (the roles changed, the first one started making HWs). Now cgminer doesn't start at all, I have only: " [2014-01-24 18:53:56] Started bfgminer 3.9.0". I've tried with option "--icarus-options 115200:1:1 --icarus-timing 3.0=100" and without.
What to do?

get another hub, or hub psu, it's not providing enough power for 2 devices
