Topic: [GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher - page 59. (Read 365630 times)

I know it isn't an issue with scryptguild as I'm running the gridseed I have on it and it's been running for 5 days straight.  The only difference is I'm running it on Linux on a pi :/ Sorry it doesn't really help since you are running windows but I can confirm no issues with scryptguild.

2.1mm plugs do fit and I would say they are better really as a slightly tighter fit is a good thing. I would strongly advise against using those octopus cables though as the wires in them are so thin its a joke. Definitely useless for BTC mode and not even good for LTC only mode as even if they dont get hot you dont need any extra impedance to increase power line noise.

Has anyone successfully run these hanging off a Linux-CGMiner box that is also running GPUs? I am considering two instances of cgminer, one for my 280x cards and one for these?

Apologies if I missed this earlier in the post. I went through the whole thread and I think i have seen it implied.

Thanks,
Woody

The link points to connectors which are 2.1mm in size, I thought that they were suposto be 2.5mm? Anyone tried this specific connector to see if it fits?

I've been having a problem with my miners disconnecting and just showing "dispatching new work toGC3355 LTC core" and nothing else. WTF???

It started happening after I pointed them to ScryptGuild.com
Before that, they had pretty much "yay" hashed full time without any interruptions.

Does anyone know if a pool server can cause this to happen? Make them quit running by perhaps, quit sending work to them for a few minutes which causes them to just - hang?

I don't think it's the USB hub causing it.

This happened 6 hours after I signed up with ScryptGuild, then another 2 hours after that, then another 18 hours after that. It's not the USB hub or lack of power causing it.

To get them running again just now, I have re-set all the ports using disable-enable which saves me from having to physically unplug and re-plug each one. I'm going to figure out a way to make this problem 'auto detect this failure and run disable-enable for each port automatically so they keep on hashing.

I have also disabled the power saving feature on each 'root hub' in device manager just to make sure WinBlow$ doesn't cause it to happen too.

I'm using Win7. I don't know if XP allows one to make these types of config changes or not.

I"m not interested in putting up with this disconnect shyt! I am sure no one else is either

mini usb is the plug that goes into the gridseeds

could someone PLEASE tell me exactly what type of USB Cable end goes into the gridseed so that I know what to buy when I visit Tigerdirect today - thanks. I can't make it out from any of the photos.

thanks

sweet
that's almost plug and play!
bought it

thanks

From someone else's post:

any tips on how too hook up 26 units on one power supply?
that' a lot of wires ....

26 is OK depending on your hubs power usage.

Lol Thanks Eric

Wrong calculator:

Assume 10W per unit as a safe load so 36 units would hit 80-100% on your power supply at 900 clock.

I'll edit my above post.

And think a little next time.

May I volunteer my escrow services if you guys are going to order a few hundred to a few thousand gridseed pods? Noted about the power supply, I'll go test it with one unit first.

Unplug the USB then plug it back in... run cgminer... should pick it up this time, then once you see accepted shares launch cpuminer and it should start as well...

I had issues with this where after starting and stopping, it required unplugging the USB before it would pick up again.

WARNING
12v 30A is 360W, so around 30 units max.
I think you mixed 120v and 12v in your computation.

thanks mate, why would I cut of the fan though?
does it stay cool enough from the natural airflow it generates?

anyway, it's more than enough, I was looking for permission   to hook up 26 pieces (2 13port hubs on 1 RaspPI) on one PSU

Okay so I tried the dual mining last night and I know you have been dealing with this for a week if not more. I get cpuminer not doing work and cgminer for BTC just freezes. When i run it just has cgminer 3.8.5 and thats where cgminer hangs. Thanks

UPDATE
On windows 8.1 you have to do a double tap. Start CGminer 3.8.5 then start CGminer 3.8.5 close the one that doesnt work. Leave the one open that does.

Part 6: Power Usage, Clocks, Temps

That was for 10 units.  103Watt at 120V is .85Amps (.085Amps each device) If you cut off the fan and use a higher rated PSU this would be 50-70 Watts vs 103 Watts.

EDIT: Wrong calculator. 

Assume 10Watts per device in scrypt only with the Fan attached.
You are at 36 units max so use 80% safe load to leave 20% headroom you are at 28 devices.

I'm in for another 30 or 40

Hello guys,
How many gridseeds can I connect to following powersupply if they were running Scrypt-only/overclocked at 850Mhz (take 900, just to be safe)
12v 30A switching power supply
Is there any danger involved if I hook up too many?
