[mazedk]

Does anyone know if theres any .eu importers with stock?

[stewmath]

Is there any sellers in the UK i can buy from??

I can buy from aliexpress for around £157 a unit with free postage

Do they not scam you?, i guess its easy to fake feedback

I ordered one off eBay so I'll be looking forward to getting it.I have a question about that USB controller that people sometimes recommend for these.What does this controller actually do?Does this connect the ASIC directly to the internet without the need for me to run a computer 24/7 to run this?As I haven't seen a clear description of it's purpose anywhere online,not here,not eBay etc.

I would appreciate some clear guidance on this as I'm looking for a way to run 1 or a few in future independently from a computer,while still being able to manage and change settings remotely.

Thanks

I am in your postition somewhat as I own two of these and run them on a pc.  In fact I can only get one to run on the pc not both.

In my case I have 5 pc's running gpus to mine various coins along with the gridseeds and  some btc usb sticks.

I have 4 more gridseeds on order. this will bring me to 6 gridseeds 5 pc's 8 gpu's.  I think I may need a controller

I don't recomend the wiibox or lightening asic controller.  People have had much better luck using PC's or RPi's

Not sure why you can't just plug these into your current miners since they are running already 24/7 (I would hope)

Not sure if you realise it but that's a link to my profile,not an actual guide.You should take a closer look at your links next time before posting.
Would adopt a Raspberry Pi except I don't know how to use one for this purpose so I thought one of those controllers would give me a better chance but I guess I'll have to look into buying one of those mini PCs instead (with Atom CPUs and run windows) so I can finally free up my MacBook Pro for other things and retire that noisy,hot GPU mining rig (old desktop)

Aliexpress? LOL Good luck!

The controllers get a lot of bad reviews for reliability.  It seems to be more stable running on a bit higher end hardware.  There are simple guides for installing on windows/linux/pi all over.

I can say that without a doubt these things are easier to run WITHOUT the controllers. I've been going back and forth with 12 of them and a controller ALL DAY. They will connect and mine for some period of time then out of no where disconnect while still drawing full power form the wall..

I think I'm going to try to dual mine with a PC and if that doesnt work I'll go back to single mode and mine LTC only. It sure would be nice to have 200ghs of BTC mining though.

Hi all, i made a video how to install this new gridseed asic miners.
The included software is the same for the dualminer usb erupter of the 5 chip miner unit.
https://www.youtube.com/watch?v=rWa6EDjWii8

Latest Software can Downloaden here: http://www.bitcoinupdate.nl/1/post/2014/03/dual-miner-setup-software.html
We now have the Gridseed 5 chip miner (300-400 kh/s) in stock and are selling this right now


Hope you like the video

Anyone has experience in how many you can run off one computer? Say I can find one or several USB-hubs , how many will run off one pc? I read they suggest 10-15 per 1 raspberry, but I have several mainboards/psus.

You guys think 100 per computer could be possible? 11 USB hubs with 10 ports and own powersupply should do the job. Thoughts?

Isnt there a 127 device limit on USB? Dont know if thats per controller or within the OS though.

I've got 20 running on one PC right now and they are all working great. One things I've noticed for those of you running cgminer to control these things. My pool was reporting about 75% of what cgminer said my speed was. After switching back to cpuminer (one instance per miner) I'm seeing average speeds of 355khs on my pool now.

I think its or the controller, but i imagine windows itself can only handle so many.

keep in mind the bandwidth. 100 gridseeds sending a few kb back and forth would overwhelm the capacity of USB2 controller and likely cause some bad latency issues

[forzendiablo]

i got mine yesterday and im mining SUN with them right now just not sure how to run dual mode to do some CTM

[User705]

Best place to buy a single unit in the US? And also if these work as well as advertised best place to sell my current rigs?

Probably go with zoomhash. His prices are actually pretty good considering importing is around $150 for 200+ units and worrying about customs and import tariffs

$150?  Isn't it $160 before shipping/import costs?

You need a Powerd hub to, no problems whit 30 gridseeds.

Can an electrician help me out.... or armchair electrician!

I'm trying to figure out a custom power setup using ATX power supplies for Scrypt mode only. Would something like this work?

Utilizing 12v PCIe Cables:
PSU -> PCIe cable -> PCIe 8 pin to double 6 pin Splitter (could be replaced with 6 pin to 6 pin splitter if neccesary) -> Two PCIe 6 pin to double 6 pin Splitters -> Produces 12 hot and 12 ground wires after cutting off the ends -> 12 barrel plugs per PCIe cable

Utilizing 12v Molex Cables:
One 4 pin Molex Cable with 3 connectors -> Splitter all on three connectors -> Produces 6 hot and 6 ground wires after cutting off the ends -> 6 barrel plugs per Molex cable

Utilizing 12v 8 pin CPU Cable:
PSU -> CPU 8 pin cable -> Produces 4 hot and 4 ground wires after cutting off ends -> 4 barrel plugs

Assuming I used a Corsair CS750M PSU (http://www.newegg.com/Product/Product.aspx?Item=N82E16817139061) it would have:
Four 8 Pin PCI-E Cables -> Splitter -> Double Splitter -> 12 barrel plugs each -> Powers 48 Gridseeds
One 4 pin Molex Cable with 3 connectors -> Splitter all on three connectors -> 6 barrel plugs -> Powers 6 Gridseeds
One 8 pin CPU Cable -> 4 barrel plugs -> Powers 4 Gridseeds

58 Gridseeds total powered @ 10 watts each = 580 watts = an efficiently loaded PSU imo.

There is 62 amps on the +12 v rail of that PSU... by my calculation up to 744 watts. So I could probably power more gridseeds if I wanted to? Any ideas of how to add more units easily?? Possibly by adding more connectors/adapters?? using the ATX connector? I liked the idea of using splitters because I can just cut off the end and jam them into the barrel plug connectors pretty easily.

$6.50

The 6 pin to 6 pin adapter: http://www.outletpc.com/jp1932.html?gclid=CNvu3ZXQlL0CFSNp7Aodmh0A2A

100 for $24.21

Any ideas to reduce costs??? Source the splitters somewhere cheaper, add more adapters/splitters? etc.

Note: If you try this, it is at your own risk. I'm not positive this will work but I don't see why it wouldn't...

thanks guys. In the picture thread I found someone powering 100 grids from two computers. Will let you know soon how many we can run off one pc

There is a theory that you can run up to 127 gridseeds per USB controller.

I think it's practical to manually set the limit to a lower number unless you actually have 127 units to test this on.

The next step is to then try and see how many USB controllers your system or motherboard has, otherwise you could just buy a PCI USB expansion card, then you are limited by how many slots your motherboard has.

For most people, this should not be an issue. You could theoretically run 240+ on just one motherboard, on the assumption that there are two separate USB controllers (north and south? or whatever). And an additional 120 per PCI USB expansion card.

The next issue is what OS to run, and RAM requirements. Litecoin BAMT 1.3 runs on less than 1 GB of RAM mining 5 GPUs using cgminer, and it loads on a USB flash drive as well, saving you the cost of a hard drive or SSD.
