received mine but im kind of upset about the lack of development haven't figured out how to mine bitcoin on it just litecoin with cpuminer on windows
Is anyone else mining bitcoins with these? I think only people with controllers are doing that. That's a real downer. Will this be fixed soon? I hope so. |

BTW, one of the cards is in a PC since I was only able to put three cards on one of the boards.

OK.... Bare with me here, this is my first time selling on this forum. I have NO BOXES OR ORIGINAL PACKAGING for any of the items for sale but I will package them very well so they dont get damaged. Most of the video cards are R9 270's, some of them are 270x's, there are also 4 7970's (2 of them are Diamond and the other two are XFX) and 2 HD6870's with VF3000 heat sinks and fans on them. The power supplies are: 2x 1300 watt EVGA1x 1200 watt cooler master gold1x 1000 watt EVGA Platinum 1x Corsair AX1200iThe R9's are as follows. 2x His H270QM2G2M 4x Gigabyte Windforce (with 3 fans)2x MSI Gaming Series4x Gigabyte Windforce (with 2 fans)2x Diamond R9270XD52GThe tech benches are all BTC XL-ATX from www.highspeedpc.com Tech benches no longer for saleI'm not looking to get rich, just looking to get rid of all the heat and noise!!! I took pics and planned on coming home to get screenshots of hash rates on the various rigs but the PC that I VNC into at the office is not letting me in (it was locking up like mad today). I do have pics of the rigs with all the cards (not with my stupid user name though, DOH!). If I can figure out how to post pics here I will. Reasonable offers will be accepted. I'd like BTC/LTC for the cards. Escrow is fine but your going to need to find that agent and pay the fees. Buyer to pay shipping upfront. ESPECIALLY if I have to ship over seas. Shipping from Dallas-ish Texas. Obviously if theres no interest in the cards selling the power supplies and tech benches wont happen. Like I said, bare with me here. Not sure exactly how this is going to go.... Hopefully smooth!  |

I found an old 1 amp 12V power cord - does anyone know if 1 amp is enough for scrypt only mode?
Scrypt only would be fine so long as they do in fact hash at 7 watts as advertised. As a single miner without a controller you can not disable dual mode so that 1Amp supply will not work. |

Still no trust ratings on the OP. Without reading for 7 pages, can someone tell me if this thing is legit? If it is, I will buy some.
If it's up in the air, I'll buy some using escrow.
Check out my ebay and amazon ratings. Also, I think many people have already received an asic from me  I'm one of those people. I received 11 miners from Zoom. Ordered on Saturday and had them in my hands by the end of the day on Monday. Will leave positive for him right now. |

Zoom, keep me posted. Thanks!

Have you thought about buying a Raspberry Pi?
I have but at last I read the code wasnt freely out there to upload to the Pi. Plus I know diddly (less then diddly actually) about using them and how to upload stuff to them. I suppose I just need to be patient as Zoom has promised to take care of me but I just want these damn things to work as advertised. |

Will these be able to adapt in the future and keep up with changing software?
In the opinion of those who bought some, should I just buy GPUs? Is it worth it? I can get 350-400 khash/s out of a GPU for half the cost.
I love the idea but think maybe I should wait for better revisions and/or competition to hit the market.
I'm trying to lower my power footprint which is why I'm buying these things. But, if your strictly asking about ease of use/price, I'd go with GPU's. In order for me to get these miners to work I have to have them spread amongst three computers and have separate instances of CPUminer open. Talk about a big PITA.... Zoom.... I REALLY need that controller.... I want to buy more but I'm not going to unless I get a controller.... |

Yo Zoom, any new news on the controller that I'm supposed to get?
|
|
|
|
I've got an Avalon 60ghs on fleabay right now. |

Assuming that the controller fixes these things I was thinking about making a piece of wall art out of them to hang over my desk. |

The PCI-e cables can also be used.
That was my original plan but Fry's didnt have ANY PCIe extension cables. I wonder how that place stays afloat sometimes. I cant tell you how many times I've been there looking for something fairly common only to not find it. Ugh... I ended up using the 4 pin drive connectors and the miners all seem to be fine. I'm sure they will be even better in single mode when I get my controller. Speaking of the controller, anyone know where I can buy JUST the controller in case the supplier doesnt come through? |

We are getting a new update for the controllers that should solve most of these issues. Will let you know!
That would be great. I'd like to see these issues resolved as I plan on ordering more of them when they are. |

Miner 1 added 55 watts to the total load, miner 2 added 60 and so on and so on.... They are all getting very warm but none of them have crashed. I have them all powered by a single 850 watt Corsair gold rated supply.
Would you mind elaborating on this -- using a single 850 watt corsair PSU? 1. Are you doing both BTC & LTC mining with this PSU? 2. Can you tell me how you wired this up? Sure. I'm trying to mine LTC only but as I found out without the controller the miners come up in dual mode even though I only have an LTC pool in my .bat file that starts each miner. Since the miners are supposed to only draw 7-8 watts in single mode only my 850 watt supply is more than enough to power them. As it stands the draw on the supply is close to its limit which is why I only have 9 miners connected to it right now. I powered the miners by getting 5.5mm x 2.1mm (YES, 2.1) barrel power connectors (not sure what the technical name for them is) and a bunch of 4 pin molex 12" Y adapters. My plan was to power the fans on each unit via +5 from the molex but after I discovered that they are running in dual mode I abandoned that idea (the one miner I modified was getting way to hot with the fan supplied by +5). I cut off the male end of the Y adapters, removed the +5 wires from the connectors (since I'm not going to use them) and soldered the ground and +12 wires to the barrel connectors. A little heat shrink tubing and were off to the races. If you want me to I can take some pics of the power adapters I made and post them. I just read that some one modified bfgminer to support these things.... Going to try it later. I really need a damn controller to get these things to run in single mode. Kinda not happy with them right now. |

Is the Gridseed controller required to run these units or can I run 10 of them from a PC using USB hubs?
You can connect these to a windows PC and run the custom version of cpuminer so no you don't need the controller, but for the extra $ it's worth it considering how many watts a PC uses...that and you'd have to run like 10-MS DOS windows of cpuminer which is just a clutter on your desktop if you're actually also using the computer for non-mining stuff. My understanding, too, is that if you mine with your PC using the custom cpuminer, the bitcoin cores will stay active and draw power...so if you only want to mine Scrypt coins with them, you'll be paying more in power to run them that way. I can confirm this. I ordered 11 miners and didnt get a controller (it wasnt shipped with them). I've had to connect them to a hub then to a PC (a few actually, CPUminer doesnt like double digit com port numbers) and run separate instances of CPU miner to get them working. Clocked at 800 MHz they are just now starting to break 300khs (some of them have been up for almost 12 hours). But, all of them are running in dual mode. How do I know?? I put a Kill-a-Watt on the computers supply before I started any of them. Miner 1 added 55 watts to the total load, miner 2 added 60 and so on and so on.... They are all getting very warm but none of them have crashed. I have them all powered by a single 850 watt Corsair gold rated supply. From the sounds of this thread the only way to turn off dual mode is to use the controller they were supposed to come with. It also sounds like the controller connected miners crash or restart quite often.... Gota love the Q/A on these things. Really hoping to get this worked out. The whole point to buying these things was to reduce my power footprint. Yeah, its lower then the equivalent GPU rig but its still not as low as I would like it to be. |

right now I have 10 miners doing 2.06 Khs.... Ugh...

Question for those of you that have a controller for these things.... Have you verified power usage when running in single mode? I've got 6 of these in an enclosure running CPUminer to mine and they all went into an over heat/shut down while mining LTC ONLY. Thats kinda lame. The other three are out on a workbench and they seem to be OK. Only three of them have reached over 300khs and this is clocked at 800 mghz. I'm sure the controller is the "missing link" here but I'd really like it if they worked better without a controller. Oh well, price one pays for getting in on new tech. You might want to disassemble the overheating units to verify that the thermal pad is making contact with the chips. Someone reported that the fan wires managed to get wedged between the chip and pad. The other thing to keep in mind is that the units won't be necessarily stable at 800 MHz. I've made it a habit to take EVERYTHING I get for mining apart to inspect it before I power it up. All the Avalons I bought had loose screws, all the Antminers I bought had loose screws and even these Gridseeds had loose screws. I did make sure that fan wires were not pinched and that the thermal pads all look like they are where they should be. Only one of them was obviously out of place and I found that before I powered it up. My problem with not running these at 800 MHz is that this is the ONLY way I've been able to get a few of them to reach above 300khs's. One of them is sitting at under 100 right now. Piss poor.... I'm curious to know if people with controllers are getting different results. |

at this point a controller would be REAL nice. I had to spread these miners amongst three computers since I only had a few lower COM ports available on each. |
