I only run a single gridseed, and it is not mining BTC... it is pointed to the TAK pool at minebig along with my other ASIC. Just a personal choice as I have been making damn good profit off it even with the trouble it is having right now. Scryptguild is where I am pointed now as well.

I am less concerned with making profit off this little guy, as I bought it with $1 worth of electricity via my profits from TAK on day 4. My ASIC currently costs ~$.5 a day to run... I sold 4 days worth of TAK starting from launch for a whole BTC and then used that to buy my gridseed shipped overnight and a PSU block for less than half a BTC... therefore... it cost me less than $1 in all reality.

Sorry, you lost me.
*How much are you making per day mining at minebig? What is the URL?

Dunno because I do not look at it in the way you do... I am mining for future sale at much better prices... I have a 34 GH/s ASIC and the 6 GH/s from the gridseed pointed at the tak.minebig.com pool.

*What is TAK? Is it a website? Can you provide a link to this?

Takeicoin but it is now being rebranded by a charity group into TakeActioncoin. It has had a rough ride the last few days but the arbitrage is continuing to fill my BTC coffers.

*You state that your pointed at ScryptGuild.
Are you pointing all of your miners there now or half and half or what?
I'm using ScryptGuild right now too. I'm still testing to see if they can actually back up their claim of providing me with 30 to 40% more profit per day than just mining straight LTC at LiteCoinPool.org

I only have the scrypt core of my single gridseed pointed at scryptguild... I do not care to speculate that they can make you 30-40% more than LTC mining because that is a broad statement you can make mining ANY scrypt coin from the top of the coinwarz chart.

*How exactly did you work it out to buy a GS3355 for $1, exactly?
Thanks

Simply that I mined Takeicoin from launch and after 4 days sold my entire stash for 1 BTC then turned around and bought the gridseed from Zoomhash. On my 34 GH/s ASIC that is about $2 in electric costs, which is my only overhead as this miner has paid itself off repeatedly already due to good mining choices. I took half of that BTC and used it to pay for this gridseed. So from an absolute cost standpoint... I came out of pocket ~$1 for the gridseed.

Only 35 running right now and 60 of the total 80 i will have. Need more barrel plugs the chinese vendor screwed up  Sad

Total   16,595.46 KH/s   Shares:1,760,128/14,464/0/0/0

35 gridseeds @ 850 + 8 r9 280x's

Scratch my last post, I downloaded the "fixed" version for LTC only.  Grin Grin so far 33W for 3 units (I am powering other smaller things also on this.)

Hah! Cool! I was coming to your rescue when I saw this. Yep, mining Scrypt at such high wattage rating really sucks!, eh?
Glad you got it sorted out.

I have sort of the same question:
is there a consensus on what's best hashwise: raspberry / windows PC / wiiboard?
Another question:
Is anyone dualmining these, or strictly scryptmining?

Consensus is whatever you have available that does not require more cost to use as a mining platform is best... if you have the controller... use it... if you have a Rpi... seems like a great way to go... if you have a PC then take the OS that best fits your needs... Windows if you have little Linux experience and less than 10 devices total (you can do more but the batch files and COM ports start to be hectic) or Linux if you have the experience and want to use dozens of devices without a ton of extra work scripting batch files.

I am dual mining on Win 7 64 and have had zero issues thus far... 6+ GH/s steady and 300+ KH/s (gotta use the cpuminer to dual mine so I do not have a reliable hashrate other than the pool).

how many gridseeks do you have -  6GH on a few can only be generating pennys a day at the most.... right?

Yeah, I'm curious about that too. I mean, if my 5 GS3355 5 chip miners can generate even $5/day mining btc, I might go that way bur right now they are making between $7 and $12 / day mining Scrypt only...

Thank you miaviator, nice guide and easy for someone like me to follow, I have however two questions.

1) my miner works for about 5 min submitting shares then just continues to "dispatching new work to gc3355 ltc core"? Exactly 1 min apart

2) the default core speed of 600 seams a little low according to your guide, Should I try and get around 750 with it?

Okay, sounds like a possible comm port overflow issue.
My PC's UART just can't handle constant flow traffic on Virtual comm ports.
Anyway, set your transmit buffer to 14 and see if that helps.
Right click computer, then properties/device manager/ports(comm & lpt), right click desired comm port, properties/port settings - set - bits per second to 115200 - data bits 8 - parity none - stop bits 1 - flow control none - click Advanced - leave receive buffer set at 14 - change transmit buffer to 14, right click the comm port in the listing that you just reconfigured, right click then click scan for hardware changes.
This will refresh the comm port/s so they are now seen by the machine.
After that, unplug and plug in the USB port in question. Unplug, wait 10 seconds, plug back in.
Set your GS5 clock to 850MHz. Then start it up and let it hash! That's the best performance you're gonna get out of it;). Happy hashing!
Doing so helped me and one other person on here. It's what I came up with as a solution to the problem you are experiencing but with 5 or more GS5 pods.
Let me know how it goes.
Good luck!
Wolfey2010

Thanks for this, At first it did not work, But then just did for some reason? But it's mining now.

Also, Each unit is using 60W of power and running in "single mode" is this right?

I am using the CPUMINER supplied on this OP.

Does anyone know if a single unit from Zoomhash includes the barrel power connector???  I want 20, but plan on using a RPI, so I dont see the point in spending the extra $$ on the controllers.

My single from zoomhash only had the mini usb, no barrel connector

Ah, didn't think of doing that! Did you happen to see the difference in amps?

It was drawing 0.017 amps at 120 volts with nothing plugged in (2 watts).
With all 10 ports plugged in, it drew .035 amps.
When they were all mining, it drew 0.57 amps (6.8 watts).

I am going to get the 24 port monoprice hub. It has 4 amps of power, which is 20 watts of power, which should be more than enough. It is also USB 2.0, which is the best the Raspberry Pi can use (no USB 3.0 drivers). I wanted the 28 port Manhattan hub, but that one has USB 3.0, so is not good for the Raspberry Pi.

I figure I will put most of the miners on the Pi. That will give me 2 controllers to babysit any marginal miners.

I haven't got any, so I'm trying to decide which to buy.
My mate is a linux expert, so that's no issue

what pool are you BTC mining at?

I have a question - I have a 20 pack on the way from zoomhash and wanted to know what PSU you folks would recommend?

aside from my pc to hook them all up to - am I going to need anything else? I ordered their kit which comes minus the psu.

thanks in advance...

Anyone know what the USB power draw is for each Gridseed 5 chip miner?

I measured the power draw of the usb hub lightningasic provided. It drew 2 watts with nothing connected. With 10 miners mining, it drew 7 watts, or .5 watts per miner.

I don't know if that is the miner drawing the power, or the hub increasing power usage to transmit data.
Ah, didn't think of doing that! Did you happen to see the difference in amps?

Has anyone successfully updated the firmware on the gridseed devices?

How would one do that? I got the red devices with a physical flash firmware button thing.

The gridseed unit also has a button but you have to take the heatsink off to get to it. When pressed while plugging in the USB it registers as an unknown USB device.

Everything has been going great. Clocked the units to 900 and now my pool is showing a lot different speed than cgminer.

Pool is only showing 5.2 MH/s. I guess just put them back to 850?

man you got a crap ton of hardware errors.... I have like 2 or 3 errors in the past 3 days on my RPi running 20 units

Danny





Same clock? I'm in a similar situation and kinda wonder what to do or if I should blame cgminer. Lol

Not cgminer... its the ASIC itself... not hardware wise either... i believe it to be firmware related. I get the same thing at 900... high hashrate locally... shit at the pool... you can watch share speed to see it is WAY slower to find shares compared to 850... that is not a hardware issue at all... that is flimsy firmware that needs to be updated.

Have any of you guys updated the firmware? Idk if an update is even out. Also my unit that is having issues has a more uneven heatsink then the other. Might be an issue as well.
Have you taken the unit apart, a couple of mine had the two wires for the fan stuck in between the heatsync and the chips.  So the chips were not contacting the heat transfer pad because the wires were in between. 

Yes, one of mine had the same problem. Talk about carelessness! Just inexcusable! I guess that's what happens when your using slave labor to do the assembly work! Cheesy

what usb hubs are you using?

What speed at you clocking them at with your Anker 3.0 hub? 850+ or 900 or what?
Thx

I am using those 60 dollar anker hubs... Might be the reason
