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

[sandor111]

why is there not a similar com option to set all 5 together?

What's wrong with --gc3355-freq=\\.\COM20:1163,\\.\COM21:1163,...  ?

Or just --freq=1163 if you are running them all the same.

Well shyt, Suchmoon, I actually guessed and tried --gc3355-freq=\\.\COM20:1163,\\.\COM21:1163, and it didn't work.
When run, I get the response, Mp GC3355 devices specified, please use --gc3355-detect o-detection, or manually specifiy with --gc3355=DEV0,DEV1,,,,,DEVn
I don't know how to find out what each miner's dev name or number is...
Do you?

Thanks for trying to help!

So how did you make the screenshot then? You had to specify the device names and the frequencies somehow?

You can look in Device Manager to find the COM port numbers.

Hey, give me some credit, eh? I mean, I'm no longer a newb 
Yes, the standard cpuminer command line, as such, is:
minerdoc --freq=1163 --gc3355=\\.\com2,\\.\com4,\\.\com5,\\.\com6,\\.\com7,\\.\com8,\\.\com19,\\.\com20,\\.\com21,\\.
\com22,\\.\com23,\\.\com24,\\.\com25,\\.\com26,\\.\com27,\\.\com28,\\.\com29,\\.\com30,\\.\com31,\\.\com32,\\.\com33,\\.
\com34,\\.\com35,\\.\com36,\\.\com37,\\.\com38 --url=stratum+tcp://dosumining.com:3000 --userpass=xxxx:xxxx
That's all there is to it.

I have not tried this , but I believe you need to specify the frequency for each chip? Like so  --gc3355-freq=\\.\COM20:1163:0,\\.\COM20:1163:1,\\.\COM20:1163:2,\\.\COM20:1163:3,\\.\COM20:1163:4

IDK thought I saw that in some readme somewhere that may be worth a try

This should work: --gc3355-freq=\\.\COM20:1163

Hey, I've been having recent loss of comm with stratum and it doesn't try to reconnect after it loses comm.
I have to reset the usb hubs by re-powering them or resetting them each individually via device manager. After that they run fine for hours then just crap out again. This only started happening a day ago. I have each hub powered separately each with 2+Amp supply which well more than they need for 26 miners pulling maybe 100 or so mA each.
I have noticed some of the usb plugs are not keeping seated / connected properly and I have to wiggle one or two of them to get them to connect better again but even if one fails it causes only 10 or so of them to quit working due to the daisy chain setup I have going.
I have 3 hubs each daisy chained off each other.
The main hub feeds into my laptop USB port where it's controlled via cpuminer.
Anyone having similar issues?
It's not the internet connection causing it because if/when it does go out and comes back up, the system simply reconnects and starts accepting / submitting shares again.
Weird.
Any ideas?
Thanks

GC3355 device detection + serial string display has been added for Windows.
Binaries are updated, current version is 1.0c
Edit: You can now also set frequency by serial instead of COM port.

Sandor I tried replacing COM numbers with serials in my BAT file but it didn't seem to work, it just sets everything to 850. My config:

minerd-gc3355 --freq=850 --gc3355-detect --url=stratum+tcp://multi.ghash.io:3333 --userpass=user.1:pass --url=stratum+tcp://xxxxx.com:3333 --userpass=user.1:pass --gc3355-freq=\\.\8D6E30845355:850,\\.\8D6E30845355:875:3,\\.\8D6E30845355:875:4,\\.\6D91458E5748:850:0,\\.\6D91458E5748:825:1,\\.\6D91458E5748:825:2,\\.\6D91458E5748:850:3,\\.\6D91458E5748:825:4

pause

EDIT: oops maybe I should remove the \\.\ prior to each serial... Yes that worked.

Nice work Sandor loving the new features.

Sandor111 thanks for the gpuminer for the gridseeds.

May I ask how I get the serial?

Just start the program as normal and it shows in the log and permanently displays at the top of the display. Its a 12 digit string.

It seems that one of my Gridseeds is not actually hashing. See the pic to get what I mean. This is confirmed by my pool speed of barely 3,000 khs.

I rebooted the raspberry several times to no avail. The only difference is that the #Gridseed changes (here is #3, before a reboot was #4).
I got this batch a few days ago and in the first days all 10 were mining.
Now I don't even know how to find the culprit: can i disconnect one by one while they are operating without risking to damage others?
Any advice? tia
 
@darkfriend77: it was a batch2 from you. Is there a warranty?

it's running just han;t gotten any shares to work on.

give it  some time or join a larger pool

Same Problem, it´s a faulty Miner. Got refunded my 70$ from minereu.com.

Well, I am preparing myself for my Raspberry Pi Model B RASPBRRY-PCBA512 Broadcom BCM2835 700MHz ARM1176JZFS.

-
Steps that I have prepared myself so far with.

A1). Installed SDFormatterv4.
A2). Installed Win32DiskImager-0.9.5.
-
~
-
=
Goals:
=
+
B1). Picking an image. SCIPTA or HASHRA
B2). Asking if Sandor111 program is supported in either images of SCIPTA or HASHRA.
B3). Asking which Image would best fit me or my setup?
+
-
Description:
I will be running five volt modded for higher overclock and fan volt modded 5-chip gridseeds. +one unmodded untouched as for now 5-chip gridseed. Grand total of 6 gridseeds.

Notes:
I do have a little experience with debian based OS's like, ubuntu, linuxmint.

I've used Scripta with three different versions of cgminer. While that rig works, it's not optimal. I get occasional cgminer crashes, which I've worked around by using daemontools to keep the miner software running. Sometimes a GridSeed will stop producing accepts, so I have to bounce cgminer. And lastly, there are certain features of Scripta that have just never worked for me (including the graphs).

If I was starting from scratch, I would go with Minera and Sandor111's cpuminer. I've been running that combo on a test rig for a couple of weeks and am happy. I've found cpuminer to be very stable, and it's auto tune function gets you close to optimal per-chip frequencies without a lot of messing around.

I'm hoping to move my main rig to Minera/cpuminer this weekend. I'm waiting on a new Minera feature of running cpuminer as a service.

So take a look at this thread. The OP (michelem) has a Raspberry Pi image:

https://bitcointalk.org/index.php?topic=596620.0

It's good that you have some *nix experience. While all of the above mentioned images strive to provide a mining appliance, there will definitely be some work that you will have to do to update, troubleshoot, and keep things running.

[wolfey2014]

Hey, is 'any frequency' supported in the latest version of cpuminer, ver 1.0c ?
I presume any frequency means you can step it at 1Hz increments too?
Thanks

It seems to be.  I have one of my miners at 1170Mhz.

Once again formatted my test SD to use with my testing rig, this time with Minera+cpuminer. I've been having the following problem:

Stratum just disconnects randomly. I don't know if it's a cpuminer problem, but i presume it is since Minera is working perfectly. Any workaround for this? I have to keep resetting this rig.

Tip sent to "edonkey 0.00433728" and "sandor111 0.01069322"

Wow! That's unexpected considering how little I did. Sandor111 and michelem have done all the work.

Anyway, thanks very much!

[wolfey2014]

Let me RECOMMEND CPUMINER Ver. 1.0c!
It has to be the best work Sandor111 has done on this program yet!
I LOVE it!
Thank you Sandor! Very Well Done!

[wolfey2014]

Let me RECOMMEND CPUMINER Ver. 1.1c!
It has to be the best work Sandor111 has done on this program yet!
I LOVE it!
Thank you Sandor! Very Well Done!
Wolfey2014

Thought the last one was 1.0c?

GC3355 device detection + serial string display has been added for Windows.
Binaries are updated, current version is 1.0c
Edit: You can now also set frequency by serial instead of COM port.

Some people call it 1.0c. I call it 1.1c 

D-OH!

New issue with one of my Blades. Every so often, I'll get one of the Blades having a "USB failure". Of course, using CGMiner, this kills the program and then ALL the Blades stop mining. 

I've tried using a different USB cable and I've tried a different power source. Nothing changes. When its mining, its awesome. Fast. I was running everything at 838Mhz, but I've gone back down to 800 to see of that was the problem. Nope, every time, eventually, there will be a USB failure and CGMiner has to shut down.

Search for FIFO Buffers in this thread.
Your solution may be there.
Good luck!
