[Guide] Dogie's Comprehensive BTCGarden AM V1 Setup [HD]

[drmadison]

I got the first of my 2 AM V1s setup today.

I'm getting a TON of errors however:


And for those having issues with it not connecting to a pool at all:
You may need to set an ACTUAL DNS IP, not just your routers IP (depending on what you use for a router). In my case (I'm on comcast business cable) it's 75.75.75.75

Everyone is getting the same % on difficulty errors. I don't know how your router wouldn't also be a DNS server, that doesn't make sense. Its a router.

In my case I have a funky network setup (my miners go through a separate gateway so I can connect to them all through a server set between them and the rest of my network.

A few other things you may want to note in the guide:

1) If you have more than one miner daisy-chained, in the Cgminer tab (the first), under the pool settings is a setting for "Board nums". This value should be set to 2 * the number of miners (since each miner has 2 boards). I fought with wiring for like half an hour before I found out about this setting...

2) My boards look slightly different. They don't have a PCIE port on the blades themselves. Instead there are 2 ports which have an adapter that can either  take a single PCIE 6pin plug (it splits into 2 cables to plug into two sides). So the 2 6-pin PCIE plugs become 4 power "plugs" - two for each board. In this case I noticed that I had a single PCIE plug split between both boards instead of 1 plug covering the top boards' two power ports with another covering the bottom two. Between this and re-wiring everything (checking all the plugs etc.) I'm down to a reasonable number of errors (200 or so an hour, vs. 10000+).

I can take pictures of my version of the boards I have if it'd help!

I have the zip file downloaded. I'm uploading it to mega and will post a link when it's done in about 15 min.

Dogie,

Wuff a corsair 750 CXM power 2 units (4 boards) or should I get a bigger PSU?

I'm running two off of a CX750 - seems to be fine!

[ZBC3]

Thank you!

I've got 1222 GH/s hashing from 4 units with 2 corsair cxm 750's.

So far so good! Thanks BTCGarden.

It's even better knowing that I got my AM-V1 miners before a single S3 was shipped!

Anyone run into the issue of hashrate dropping after a few hrs?

Its pushing the power down each cable strand quite a bit, but overall power consumption is fine.

Yeah, sometimes CGMiner just needs to be rebooted

i got my 3 miners today .. but when i try to run them everything is discarded.. any suggestion what to do here ?

Triple check the wiring from the Pi to the modules. Do just one module at a time, from the Pi to the right hand connector with fans facing away. Check red line alignment.

[Chris_Sabian]

Has anyone been able to edit the cgminer config file by SSH into the r-pi to allow for solo mine?  I have mine running fine with servers but I cannot get it to connect correctly to my node.  I think that I need add:  --btc-address  to the config file but you can't do that with the webgui.

*UPDATE*

Per BTCGarden support, the code to edit the cgminer config file manually on the pi is:

sudo nano /var/www/run.sh

Then start cgminer via the web interface

[bbeesley]

sudo nano /var/www/run.sh

Then start cgminer via the web interface

just make sure you don't make any changes via the web interface because cgminer_update.php has code to overwrite your config changes to run.sh

Try connecting the pi with a different board, as well as changing the board_num to 1. This means only 1 board is mining. You can check which board is not working properly.

Wait, discards are just shares below difficulty. If you have a high worker diff set on the pool side it can take a while before a share is over the diff and gets accepted. I don't know what pool you were using, but back in the day when I was using ghash (don't judge me they were small at the time) the default worker diff was 512 even though it claimed it was 16.

How long did you try running the miner for?

I also had a problem with all my shares being discarded. Turns out I had my wire from the RPI to the board on the wrong set of pins. Double triple check all those
