[GUIDE] GridSeed 5-Chip USB, Blade & Black Miner Support/Tuning

[daddyfatsax]

I used probably every cgminer fork ... and I want back to the first one andreed
.... which is working flawlessly and reports me on one blade around avg. 5.25mh on the pool with 800 freq ...

tryed jmordica, gynau, dbartles ... and so on all where lower in hashrate ... I remarked this already with my gs5 ... no idear why ...

...

Using a clean debian wheezy build ... following that order https://litecointalk.org/index.php?topic=9908.msg142718#msg142718

Is there a windows build of this anywhere? This is what I am using on my pi with 20 GS USB devices, and does work the best IMO.

Git and binaries have been updated.
TUI is included, and a number of bugs have been fixed.
A number of useful commands have been added, check --help for more info.

Thanks Sandor.   Working like a charm with my two gridseeds.

[csmflynt3]

This is perfect just what was needed. Can easily see what is really going on now

Thanks for your efforts

[jamieb81]

testing it now looks super!

how do you access the help ? cause in cpuminer I cannot write that command

[csmflynt3]

just run the minerd --help in a command prompt is the easiest way to see the list I think

[jamieb81]

Usage: minerd [OPTIONS]

Options:
  -G, --gc3355=DEV0,DEV1,...,DEVn                                       enable GC3355 chip mining mode (default: no)
  -F, --freq=FREQUENCY
        set GC3355 core frequency in NONE dual mode (default: 600)
  -f, --gc3355-freq=DEV0:F0,DEV1:F1,...,DEVn:Fn                 individual frequency setting
          --gc3355-freq=DEV0:F0:CHIP0,...,DEVn:Fn:CHIPn         individual per chip frequency setting
  -A, --gc3355-autotune
        auto overclocking each GC3355 chip (default: no)
  -c, --gc3355-chips=N
        # of GC3355 chips (default: 5)
  -a, --api-port=PORT
        set the JSON API port (default: 4028)
  -t, --text
                disable curses tui, output text
  -L, --log
                        file logging
  -o, --url=URL
        URL of mining server (default: http://127.0.0.1:9332/)
  -O, --userpass=U:P
        username:password pair for mining server
  -u, --user=USERNAME

i keep getting failed to open /dev/ttyACM0

I am running on Raspberry pi:
./minerd --gc3355=/dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2,/dev/ttyACM3,/dev/ttyACM4,/dev/ttyACM5,/dev/ttyACM6,/dev/ttyACM7 --freq=1000 --gc3355-autotune --url=stratum+tcp://usa-1.liteguardian.com:3335 --userpass=cxxx:x --retries=5

[csmflynt3]

working great but i think the TUI is displaying 5 mhz increments instead of 25 on the auto tune. I see my gridseeds at 845Mhz and 855 etc

It's averaging the frequencies.

Downloaded, what must be a newer version of cpuMINER and now I am able to configure each chips freq interdependently. This is truly AWESOME!!!!

Thanks for the help!!!

All i see on my minerd window is total Mhs, A, R, HW and connected to:
Cant get it to show detailed info with additional flags as well...
 
Either im missing something obvious, or new windows version has bug then running a lot of devices. Currently i tried with 30 gridseeds.

I have the same problem ... I'm using Kernel ... 3.10.37+

I don't have any ttyACM0 in my dev folder ... got 9 Blades connected thru 2 x 10 port usb hubs ... working well with cgminer ...

Anyone got -A / --gridseed-autotune option working in the latest binery? It seems broken. I'm testing in Raspberry Pi, with -D and -t option enabled.

Ah ok sorry that makes sense now

How is it broken?

Sandor would you add the coin difficulty to the TUI in the next update? CGminer shows it. Loving your work.

[Blisk]

I got it to dual mine last night, I was stuck in the back and forth of sha256 / scrypt as well. Before using zadig to overwrite the driver my com port was 4 then it disappears as stated above. I changed the com port to 1 it the batch file for cpuminer and it fired up, very slowly mind you. Once it started hashing scrypt I launched cgminer and it went to work also. I did drop the clock speed for both. I am only using one miner mind you. Currently I am only getting 250 KH/s and 8.77 GH/s

I am sure this is of no/little help but that is what I did messing around and it worked.

I will give this a try also see what happens

Update: Both are detected using com1 for cpuminer, however cpuminer is not finding any shares at all
See below:


So still no further ahead for me

I have the same problem with one miner, no shares at all, but I don't have dual mining, just LTC. Have anyone solve that problem?

How is it broken?

It accepts the --gridseed-autotune option but didn't state it has several steps to go before increasing to the next frequency, nor really increasing the frequency of any cores.

What is the full command line that you used?
