Topic: [GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher - page 11. (Read 365630 times)

I got 3 dualminer2 today as well as a Gridseed.  I am able to get them all up and running (using different versions of cgminer for each) without any problems-- at least when testing to wafflepool, scryptguild and clevermining.   
I was actually trying to solomine an altcoin directly to a wallet-- I've got a GPU box doing that just fine (host:8332) to the exact same wallet however when I point either the gridseed or the dualminers at the wallet it connects and appears to be hashing away just fine except I never get any accepts or rejects.  The hashrates the cgminers report are reasonable yet no accepts.   
 The only thing I can think of that is different between mining to a multipool and a local wallet is that the local wallet is using http (getwork I believe) rather than stratum.  cgminer shouldn't have an issue mining to a wallet-- after all I use an unmodified cgminer on my GPU box with no problems also using http.   Anybody have any ideas why this isn't working?

Anyone have any idea why a blade would hash but not submit work?  I am using cgminer on windows 7.  No matter how many blades i plug in, it sees them all, and they all hash, but the last board never submits any work (based on device id it is a different one each time but i don't know if the device id is unique to each unit or of it changes each time i plug it in).  What I mean is, if i plug one blade in, one board submits work and one doesn't.  If i plug two blades in, i get 3 boards submitting work, one not.  If i plug 3 blades in, 5 boards submit work, 1 doesn't.  etc. etc.  The "non working" board does hash though, it just doesn't submit work.  I have checked everywhere and see other people have had this issue, but not found a solution.

Any have any ideas?

For real? NICE!
That's really decent performance for a non-overvolted unit!
Have a look at today's update from http://cryptomining-blog.com
They're over volting one right now!

Perfect, thanks!

I briefly skimmed the last few pages looking for mods on the Gridseed 80, any known ones yet? Power consumption isn't really a concern, and I'm currently getting ~6MH/s @ 850MHz

Thanks for this awesome topic! Made my day

PUE - Probable User Error : LOL

and why the hell did you quote the whole OP with pictures just to say "it doesn't work"? :-)

Works not well? works fine for thousands of us here.

care to explain what's the problem?

https://github.com/siklon/usb-miner/tree/master/software/cpuminer

Short summary:
* Added hashrate statistics
* Added auto per-chip frequency tuning
* Added JSON API at port 4028 -> send {"get":"stats"} to get stats for each miner/chip
* Input any frequency you want


It should work on Rpi, but I haven't tested it yet.

Are you running cgminer as root? I think you have to do that or it won't be able to talk to the GSD's.

I have two rigs, one is Gridseed 5 chip based and the other uses DualMiners. In both cases I run cgminer as a service via Daemontools. I've posted a "how to" here in case you're interested:

https://bitcointalksearch.org/topic/guide-configure-your-miner-software-as-a-service-under-daemontools-577018

If you're on a real linux box and not a Raspbery Pi, then you can probably skip my instruction about installing ramlog because you probably don't need it.

If your cgminer still can't see the GDSs, then you can tell if they're visible on the USB bus via this command. This might help rule out a USB hub or connection problem:

lsusb -t

If you need an example config, here's the one that I'm using with the mox235 variant of cgminer (same as girnyau but with better JSON API output):


The above config defaults to a frequency of 850 unless overridden. You can see that the "gridseed-freq" option demonstrates overriding the frequency on a per serial number basis.

You have to replace "REPLACEME" in all cases above with your bit coin address. Do yourself a favor and copy and paste the address. These addresses are case sensitive, so one upper or lower case mistake and your earnings go into a hole. Change "workername" to the name you want for your rig, in case you have more than one and you want to be able to tell them apart.

I'm also using the mox235 version of Scripta as the web front end, but it's kind of involved getting it installed and working on an existing Linux system. Here's a link to the basic instructions I followed, if you're feeling up to it:

https://litecointalk.org/index.php?topic=9908.msg138403#msg138403

Remember to use the mox235 version of scripta with the mox235 version of cgminer. They've both been modified to provide improved information, including displaying the serial number and frequency of each GSD (which is insanely useful if you have more than one and want to tune them).

Note that if you use my mechanism of running cgminer under a service, you don't want to integrate the Scripta rc.local file. Also you should replace their start/stop scripts with your own that call daemontools to start and stop the miner. But frankly I just use Script for status, not control.

Also, when I leave the Scripta cron jobs on, they cause USB disconnects. I suspect this is a cgminer bug when multiple cron jobs hit the API simultaneously. Some people have successfully staggered their Script cron jobs to avoid the problem.

Probably too much information, but I hope some of it helps...

Hello all,

I have ordered my first gridseed from GAWminers, and have followed the guide to download cgminer for Ubuntu from this post. I believe I have succussfully downloaded it as I was able to get it to start up at the end, but obviously it says no USB device detected.

I have been mining with 3 r7 265's for the past month, but before that had no experiece in linux or computer building. I built my first computer and with some help was able to get my cards mining. I use sgminer and get it started by cd ~/ and then ./mine.sh.

I was wondering if there was a way to start cgminer like that, as I think the only way I was able to get it running was by calling cd ~/ then ./cgminer/cgminer -o xxxxx and all the information for gridseed after. I was wondering if there was a way to start the gridseed mining by calling on a .sh file like I do for my gpus. I am hoping someone doesn't mind answering my elementary question. I want to be prepared to have the gridseed up and running right when it gets here and not have any software issues. Will the gridseed work by running cd ~/ then ./cgminer/cgminer -o stratum+tcp://server:port -u username.worker -p password  --gridseed-options=baud=115200,freq=888,chips=5 --hotplug 30? It currently starts to look for a pool when I type that in now and feel like it should work once the gridseed is hooked up, and is there any easier way to get it running other than how I stated.

I also plan to just open cgminer in a second terminal, as my gpu's currently run on sgminer. Will this cause any problems?

Thanks!

I've got my 10 units up and running but am having problems with them shutting off. I am using the dbartle version of cgminer on a raspberry pi. They'll work great for 4-6 hours, but then will turn off and is shown as "OFF" in cgminer. I haven't changed the wiring and it's always different units so I don't think it's the hub or cables. I've got hotplug set to 30, and restarting the hub gets them all back on for another few hours. Any suggestions?

You can get them OC to 3.6Mhs per 40 Chips X 2  So total it will be around 7mh-7.2mh per blade but This pumps the wattage to over 400watt, Its cheaper to get the Gridseeds and mod them yes same wattage range but you can get more for the price, and mod them all to a 510Kh stable

meaning for 20x gridseeds @ $2000 you will have just 10.2Mh once all modded. Only difference is more space and wires.

Hi Guys,

I would like to use the latest Cgminer but I do not know how to compile it to windows? Also why doesnt this version have frequencys in small steps all the way to 1400 because I will soon be modding my miners for a stable 513kh AT 1200freq , I am very curiuos why this was not compiled using the lastest OC freq cgminer..

i want this version of cgminer that outputs the serial number and frequency for each unit - but tjis says itt only has max 1000freq

Not sure where to put this as I'm new to this forum.
Anyhow, I just disconnected the fans from my gridseeds and restarted cgminer.  After an hour I have zero rejects on most devices whereas before I had about 3% reject rate.  I don't know why disabling the fan would improve acceptance but it actually seems to be working better without the fans than with them, maybe the power is more stable or something?  Anyone else notice this?  Also, I'm running USB antminers U2 and cgminer keeps trying to use them (gridseed detect, failed to initialize)  I'm successfully using bitminter to run the antminers but i am wondering if there is a way to tell cgminer to ignore them.  I just opened a bitcoin wallet, is there anyway to test it buy getting some micro bitcoin deposited?
