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

[miner765]

Anything over 16 miners will get my cgminer to crash. Why so? It will just freeze and then crash. 16 miners work fine. Can anyone help please?

Cpuminer is the answer

I can't get cpuminer to see my miners for some reason. Just says not found.

And another question: is it possible to detach the fan from that LOUD psu? There is really no point of it and it creates so much noise. And how to connect miners to a outside psu?

Write out \\.\  before the com port, e.g. \\.\COM**, and do not use more than one Gridseed miner per instance of cpuminer.

Thanks, will try it out. What about the fan from PSU? I do think it's not necessary to cool the PSU with usage of 100 watts. Or how to attach my own PSU?

Ill just leave this here

Not that it matters for scrypt...but why do you have the miners bowing down? Those shelves do not restrict allow airflow blowing up. Would think that would be better especially for dual mining?

Hate to be posting this (especially on Pi day!) but here are my results of using the Pi with 17 miners.

Getting the Pi working was a breeze! Simply loading the OS (Raspian) and logging in through SSH (after the initial menu config) allowed me to compile cgminer just like on Ubuntu server....although a LOT slower.

After modifying the text file for stability (as posted in this thread) I fired up cgminer and it started hashing. Things were looking good and I was elated so I went to bed. I did notice that on the Pi cgminer takes from 10-25% CPU sometimes shooting up to 50%. Figured that was fine as long as the little guy was working.

Little backstory. Before using the Pi I was successfully mining using a ThinkPad laptop with Ubantu server. I took two screen shots in 24 hour intervals on that computer. First was at 800 and the second 850.

Back to the Pi...so I woke up and checked in on the Pi. Was disappointed to see some of the miners were not hashing as fast and that the average was low. HW was also MUCH higher.

Left it hashing and went to work.....checked on the pool to see how it did overnight...not good:



You can see where I started to use the Pi at around 2:00 AM. For some unknown reason it went WAY down from around 5ish to 8ish. Overall the hashrate looks lower than the Thinkpad.

Will keep it running on the Pi for another 7 hours but thinking that it will be going back to the store. I'm sure it beats using the controllers but perhaps it's just not fast enough.

I'm running 19 miners currently on the Pi and it has not had any stability issues. As you can see in the screenshot below, system load is under 0.1, cgminer processes are mostly sleeping. Some differences from your setup: 1) I'm using scripta and a precompiled cgminer posted by someone initially on litecointalk; 2) I'm running two separate cgminer instances (10 and 9 miners). I would suggest for you to try the precompiled cgminer and see if that performs better. If that doesn't help I would start narrowing the problem by disconnecting half of your miners to see if there is one malfunctioning device that might be causing cgminer to misbehave.

No issues here running Scripta on my Pi. Only drops in the graph are me messing with stuff.

Just make the height of the cgminer bigger before plugging the USB then nothing will freeze

Just tried it. Still freezes

Well it completely stopped so I switched back to Ubuntu server on the Thinkpad for now.

Will try again over the weekend but if it hashes less and produces more errors it's gone. Just communicating my results so far.

This graph shows that it hashes slower and the point where it died (12PM) before I switched back to the Thinkpad.

Another problem appeared. When I get all 40 connected, first 10 are declared SICK. And also some miner's Accepted Shares keep staying at 0. What could be the issue?

Cool! I'm doing it right now with cpuminer for SCRYPT only.
900MHz for several minutes. Excellent!

Check hubs and cables. Test 10 at a time and swap the cables around. If the problem persists with a known good cable and hub - defective miner (unlikely). If the problem appears only after connecting a certain number of miners (again, with known good cables and hubs), could be some sort of software/OS limitation. You don't mention what you are using and I'm too lazy to check if you had posted anything earlier :-)

And this is relevant how?

Yes. Please explain. With pictures if you can.

Does it count if it requires soldering and maybe replacing a resistor?

[bttalkdim]

Is it possible to run cgminer 3.8 for BTC and in same time cgminer 3.7 for LTC ?
to mine both cores in same time with good minres.. (Windows)
I don't like CPUminer...

I can't even get it to work! lol

What are your COM port settings?
