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

[Kergekoin]

Need some help with solo mining in to qt wallet. Sandor cpu miners give "stoped responding and needs to close" error while trying to mine in to --url=127.0.0.1:port.
Can minerd be used to solo mine to qt wallet at all?

I think it still doesnt support getwork protocol

[RowanX]

can someone compile (the latest tui) for windows 8 for me?

https://www.dropbox.com/s/ttqa9p851siz8oi/minerd-gc3355.zip

According to dropbox this was uploaded 20 hours ago.. but the latest commit on github is from 15 hours ago ("Optimize locks, handle invalid ltc responses"). Am I confused or are we waiting for a newer compile?

[sandor111]

in the actual version of cpuminer ... the autotune feature doesn't log when it changes a per chip frequency nor the steps to go .. right?
any way to re-add that log output which showed which chip running at which freq?

--debug shows the output from autotune.

Just got 3 Gridseed 5 chip miners today and am trrying to hook them up to my headless Ubuntu (13.10 - saucy) machine.

I haven't had much luck so far.

Using cpuminer (per https://bitcointalk.org/index.php?topic=454127.msg5005687#msg5005687) wont let me specify more than one Gridseed interface.
When using --gc3355=/dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2 minerd states:

Code:

failed open device /dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2

Using cgminer (using https://github.com/dtbartle/cgminer-gc3355) doesn't seem to generated any hashes.
Accepted, rejected, and work per minute stats all stay on zero.

So obviously I am missing something and would hugely appreciate a pointer to current best way of using all my miners for scrypt mining.

What is the full command line you used?

I have given cgminer another go and it seems to now do some hashing. Still not sure it is at the speed it's supposed to be.
I am getting on agverage 0.6 WO / minute.

Command line for cgminer I am using is:

Code:

sudo /home/syncapp/cgminer-selfcompiled/cgminer-gc3355/cgminer --scrypt --gridseed-options=baud=115200,freq=850,chips=5 --hotplug=1 -o stratum+tcp://middlecoin.com:3333  -u 1K5qx2wsjLxKZij8WdrV1rjNi6NDsdLsDc -p x

when using cpuminer I used the following command line that gave me the error message "failed open device /dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2":

Code:

sudo /home/syncapp/cpuminer/cpuminer-master/minerd --freq=850 --gc3355=/dev/ttyACM0,/dev/ttyACM1,/dev/ttyACM2 --url=stratum+tcp://middlecoin.com:3333 --userpass=1K5qx2wsjLxKZij8WdrV1rjNi6NDsdLsDc:x

You're using an older branch of cpuminer, which doesn't support multiple devices.
Try to compile this one: https://github.com/siklon/cpuminer-gc3355/

Hello.
So is the latest brand of Sandor's cpuminer sufficiently debugged so I can use it now without crashes or other strange anomalies?
Is it stable and ready to hash 24/7 non-stop as with previous versions?
Thanks!

I'm currently using the latest windows build v0.9a. So far so good, stable and hashing away.

I have had excellent results with it on Raspbian with 20 gridseeds.

Sandor, I just want to say thank you for developing this fork of cpuminer.  It is a solid solution for those of us that want to run gridseeds on a RPi and to be able to walk away and not worry about anything.  Is the BTC address in your sig current?  I'd like to throw you a tip for making my days easier lol.

Thanks... yes it's current.

Cool... sent you a little something.

Thanks, mate!

Pushed a little more those gridseed, more a proof of concept but still interesting...so max freq reached is 1320mhz 

VMOD3

vcore:1.82Volt
power consumption: 25.8Watt
hashrate: 560kh/s
frequency: 1320mhz
temperature: 38.1°C  (measured on the heatsink bottom - fan@5V - room temp 23.4°C)





Power consumption start to be pretty high compared to the hashrate, still if you don't pay the electricity surely it's worth it.

Couple of tweaks added to gc3355 code.
Binaries have been updated.

Hey you didn't update the version number. #justsayin'

thanks for the update! woke up this morning to find the last version stopped responding last night 20 min after i went to bed. looks like it was disconnected from the strata and wasn't able to get to the failover which usually it does fine. still says v0.9a in the tui.

Nothing major added/fixed so no need.

Something has gone wrong with reporting hashes:

I found the same thing as Kergekoin.



Here's the log file https://www.dropbox.com/s/jj1yneqjcrstr81/cpuminer-gc3355.log

[sandor111]

Whoops... fixed and updated.
Edit: current version is 0.9c now

I've been using your versions fine for several days now, however, today, Avast! has decided that it's a trojan, BitCoinMiner-FA https://www.virustotal.com/en-gb/file/2ec04f3507108061aae4b28e262f941632bfa4c067f725144f7177621691eef6/analysis/1399050193/
