Topic: [GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher - page 44. (Read 365630 times)

Have a new problem now, my gridseeds were working in cpuminer, now they arent working with any software and are not showing up as COM ports in device manager anymore, they are showing up as "STM32 Virtual COM Port"......

That chart is extremely conservative to put it mildly. PCI-Express power connectors are pushing up to 6A per 18-gauge wire and don't seem to get warm let alone melt. These are bundled, often sleeved wires in enclosed cases next to 300-400W fire-breathing graphics cards. Not sure what kind of environment justifies 2.3A for 18-gauge. Maybe for transmission over long distances, not for a couple of feet.

It wasn't for the asic chip it was for the MCU on the board.  http://www.cybtc.com/thread-6262-1-3.html The beta red colored units have GD32F103C8T6 chip, which was changed to STM32F103C8T6 chip for the gold units.  The older chip was causing the red ones to crash alot when dual mining, and subsequently would need a relay to power off and on the boards every so often.  Curiosity got the best of me and I wanted to see if I could change out the chip like the thread above explains how to do.  I just got back from radio shack and now I have to correct equipment to try to fix what I screwed up yesterday.  Hopefully I am up to the task, and if not at least I will learn from my mistakes and have a better understanding and appreciation for the ones who are able to service small chips on circuit boards.  I like tinkering with things, I just made the mistake of learning on an expensive board when I should have tinkered with a cheap circuit board laying around the house.  Any how if I fail someone can take the chips off my hand if it helps them in any way, but I think that I will be able to fix my mistake.  The plan is to find where the leads go from the contact pads that I ripped off when removing the old MCU and just wire them directly.  Will see if my plan works. 

The watts for the Gridseed 5 is:

8 watts (0.67 amps @ 12 volts) for LTC only
52 watts (4.33 amps) for BTC only
60 watts (5.00 amps) for combined BTC/LTC

Based upon this chart
http://www.powerstream.com/Wire_Size.htm

The recommended gauge wire is:

23 gauge for 0.729 amps (0.67 required for LTC only)
15 gauge for 4.7 amps (4.33 required for BTC only)
14 gauge for 5.9 amps (5.00 required for combined BTC/LTC).

Given that the gauges are conservative, you can probably get by with 24 gauge (.577 amps) for LTC only mode, and 15 gauge for combined mining.

Note: If you use 23 gauge wire, and inadvertently invoke BTC mode, you risk melting the wire. 18 gauge would survive a short period of time, and may even work for a while. But, I wouldn't plan on BTC mode with 18 gauge.

Finally got my 12v stepdown to run the Controller/Raspi off the 12v supply.  (Testing on the controller since it's trash, I'll move it to the raspi after 24 hours)

Wolfey2014, it would be appreciated when you'd stop with always finishing a post with your name. Common forum stuff, your name is already on the left and you might notice that almost nobody does it besides you
 
Further it might be good to sometimes refrain from commenting when it's not 100% on topic. I do see your enthusiasm which is very good but like it has been mentioned before (probably also in other threads), when somebody asks about a problem with software A, there is no need to promote your software B (or point out that what you are using works). Even though it's better/cooler/hipper/cheaper/more effective/etc, that's not what the question is about. I've seen (so far) two annoyed responses on those "plugs" on cpuminer in the several threads I'm following and you don't really seem too happy with those remarks so far. To make a slight understatement

As a complete linuxnoob, I've installed 2 raspberries, put the suggested software on them and made 32 GSD's run for 72 hours already without a single hiccup or miner reconnecting/disconnecting. I'm -this- close to putting my version back into an image to share with everyone because it works so damn well
So cgminer (if you're into scrypt only) is a very decent piece of work, but just one of the flavors, just as your favo software works perfectly well

On the other hand, you're doing very good with your research on stuff, so keep that up, I've very happily used some advice from your posts already.

Oh, and starting a response with "no offense" but then clearly showing in your writing that you took offense is, ehm, well, an incorrect use of the term

No offense, but don't start shit where there ain't no shit to be thrown. It will only pile up on 'you'.
My opinions are backed up by fact, not fiction. READ!

LATER!

Maybe you should instead qualify that statement as "I have no idea what I'm talking about". Where did you get this: "line code intensive and you have to learn coding"? What does it even mean - "line code intensive"? Don't get me wrong, I appreciate your enthusiasm, but you could slow down on pitching cpuminer on unrelated posts and making bogus arguments like that. Feel free to highlight cpuminer advantages without making shit up.

Here here! If I had the financial backing, I'd figure out something like that, myself.
Evidently, GridSeed's HASHRA.com outlet has just what the doctor ordered.
But I do not know when they plan to release it.
One would think those guys would be the ultimate experts / authorities on the matter but, look at us all.....

Still, we all persevere. After all, these things are for generating income and growing a new world wide market and industry.

Crypto currency is here to stay. POWER TO THE MINERS!!!!!

Can anyone tell me the command for LTC mode only in the 'GridMiner' controller

HI
I have 18 gridseed miners
connected to a ras-pi running cgminer
it works very well

I did have it setup on a Windows PC running cpu miner
witch also worked very well but it was a total pain in the ass to change the pool information

that's why I moved across to a Ras-pi

Wolfey for noobs you are absolutely correct cpuminer all the way. For people with 10 or more cgminer or bfgminer. None of them are perfect yet thats for sure. Wish someone would build one that could dual mine with no extra added grief.

Yeah. I'm only running 6 right now. Wish I had a lot more though.
And at some point, I'll probably go with a different program like bfdminer.
When you're running 20 or more of these things, I am sure having one instance / window per miner becomes a bit of a pain in the arss!

I just like cpuminer because it sets up quick and it's easy to understand and apply for newbs where others require a steeper learning curve and time, plus all the other debugging issues I find rather inconvenient if not unnecessary.

Just my .0025btc worth!

I am running it on windows. So not sure i know it started on linux or one of the other operating systems and was compiled for windows from there. Its bfgminer 3.10.0 for gridseed.


you can see if there is anything that will run from here

http://luke.dashjr.org/programs/bitcoin/files/bfgminer/

will bfgminer run on the pi rasberry?

I tried the bfgminer and thats what I am sticking with. No extra drivers needed to be installed.no Plug and prey. Shows hash rate. Cpuminer requires one instance per gridseed. Cgminer requires extra drivers be installed usually have to plug the gridseeds in after starting cgminer. plug and prey all the way. 

wolfey2014, just a question here.
It seems from other comments like you need to have 1 cpuminer process for each miner, or am I mis-reading things? Can you run all 20 miners from one cpuminer process?
I kinda like the cgminer in that the screenshots I have seen show it hosting multiple miners per session, and there's no extra work involved. It seems like it should work out of the box (for the modified version anyhow)...
Im already use to cgminer from my GPU rigs, and the ability to use cgwatcher/cgremote is desirable.

Just looking for thoughts on the pros/cons of which software to use...

Nope! Not an issue, at all..
I can monitor them just fine one by one on the pool side. Weak ones show up as do the strong ones.
You'll see. Like I say, they are pretty accurate, from my experience.
You can try www.litecoinpool.org to see what I mean.
Enjoy!

One of my reasons for wanting to see local hashrate, aside from being able to tweak for max speed/stability, is that when running 10+ of these, I imagine it would be difficult to pinpoint an under-performing/defective unit, if all I have to go by is pool speed...
