[GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher

[IchibahnSLC]

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

what usb hubs are you using?

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

Another user was running 48 units with those hubs with no problems...

Could you link or PM me the exact model number?

I can't right now. Its title 50 gridseed setup or similar. He lists it in the thread.

Just buy these, they are the same hubs as Anker and cheaper!~

[BrandonMcPherson]

It's cheaper, but it has a 3A power supply, while the Anker unit has a 5A. One pays for what one gets.

Here's the Anker hub that was most likely referred to. Is there a known issue with them? I've been happy with several of them.

[CartmanSPC]

I am using the Etekcity 10-port USB hub 3A with 10 miners x2. Seems to be working fine.

I believe that Anker hub only has a 5A power supply because of the extra charging port?

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

Was thinking of replacing my Etekcity hubs with ORICO A3H10 10-port USB 3.0 4A hubs but would rather not if it is not needed.

I expected to receive the Orico hubs instead of the Etekcity from my vendor but whatever...figure I got a decent enough cost on the miners that the accessories don't matter. :/

[chanberg]

Etekcity, Orico, Anker, Aitech are all the same crap. Just different badging. But now Anker it seems is branching out as their 13 port looks nothing like etekcitys or oricos. But Aitech is still pushing the old aluminum design

And yes, the only reason Anker is 5A is because of the charging port which gives 2.1amps, and both of these give 1A to each port...

Here found another rebadged one:

But yeah i guess don't believe in the hype of Anker, just buy the 25 dollar variant!

Has anyone successfully updated the firmware on the gridseed devices?

[surgexvb]

Just thought I would chime in.  I am running 24 off one rasberry pi.  Scrypt only.  So far stable.  Using the monoprice 24 port hub.  All including hub and pi running off an atx power supply.  Running at 850 mhz.  Multipool reports 8500 kh on the 10 minute.

Used the raspbian wheezy image and cpuminer.  Command line interface only, not booting to desktop.

[daddyfatsax]

Everything is fine once I set them back to 850.

I am using one Anker 9 port hub and a 12 port hub supplied by Zoomhash. Good the see the monoprice hub works, I am going to need that once I get my Spotswood case.

Hopefully we can get a firmware update. There is a significant amount of headroom in these devices. I have not removed the fans on any of mine, my office already sounds like a jet engine with my 5 Ants, and these things stay cool to the touch even after days of running.

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.

[richmke]

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.

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.

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

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!

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.

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

[jjj0923]

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...

[Mymine]

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).
