After few days of mining I am unable to unlock account using gmail, no mails received, kinda sucks....
With me coinking emails came into the 'advertisement' section, so spam. Add the email address to your contacts and retry it again, then the email will come in your regular inbox. |

Just put GD900 thermal grease between the silicone sheet and the heat sinks, as well as on the chips. One chip had so little thermal grease on it that the scorch marks could be seen on the silicone..... Seems to have better cooling resulting in a 1-2 degree lower average. When the small heat sinks for the voltage regulator arrive I will put those on as well  |

Guys, the new A2MINI is from a new factory, the previous seriously fucked up and pissed off not only you guys but us as resellers and innosilicon themselves .
Innosilicon was pursuing for compensation from that factory, but was not successful.
But what is important is that you guys get the shinny new A2MINI now, enjoy.
It seems the power usage between the two factories is a lot different, do you (MinerEU) know where that comes from? Is it the PSU, controller, etc? Are the blades exactly the same in both? Please provide more info. |

Right, well I have it now. It's certainly not the same A2 as the first one. Differences noted so far:
Black Case
Nice chrome handle on the top
Real 400W ATX PSU
Access slot for SD card in top
A nice layer of dust on the fan, and all the internals
Brown PCBs that seem thinner
Edit - And even louder than the first one
At least you know it works... |

My A2's won't take 100 days to ROI, but even if they do, it'll all be profit after that.
I've got a 24V Meanwell running one of my constant current LED circuits at home, been rock solid for the three years it's been running. Have to see if I can get hold of one
I'd love to know what you're mining and your calculations. +1 |

I have connected everything directly to 12 volts of a ATX PSU, but be aware because in my case the + and - of the connectors on the blade are reversed from the ones from my PSU.

As I can't reach warranty@minereu.com (overzealous antispam filter that bounces my emails), here is the message I sent 2 days ago to warranty@minereu.com, posted on the Google group used for support and retried sending to warranty@minereu.com a couple of minutes ago (with another bounce) : Hi,
out of the 3 miners in order #1664, one just died.
The Raspberry is still working fine, but it can't reach the 2 blades at all.
The main fan isn't spinning on startup either. I opened the top panel of
the a2mini to check for any obvious problem but couldn't find any (no
burn trace or physical damage visible).
It seems the problem comes from the controller board : the main fan and
the 2 blades are connected to it and stopped working at the same time
while the Raspberry is working fine.
Is it possible to get a replacement for the controller board ? Better :
can I purchase an additional one on top of the replacement one to avoid
too much downtime in the future if it happens again ?
Best regards,
(sig removed to avoid privacy problems)
How can I proceed to reach minereu.com support and deal with this problem? You could get the blades working in the mean time by plugging them in (including the fan) the controller of one of your other working miners. It should work then, you then just have a 60 MH/s miner. Than you know for sure as well it is the controller. How to contact them otherwise then mail or PM I don't know |

Crap ass chinese PSU! My A2 just broke down  well the psu! That in two weeks The LED on the blades.. what color were they ? Mine are green, but what difference does this make? There is a little LED on the chinese PSU, if its green its working of its off its broken. Yes but JPS2K5 was talking about the LED on the Blades not on the PSU. |

Crap ass chinese PSU! My A2 just broke down well the psu! That in two weeks Mine is still running, and I have a spare one when it breaks. I don't understand why they use a PSU with too small capacity. There is also a 40A version, will cost maybe a few $ extra. They want to grab as much $ from your pocket as they can. Mine is running very well on a BeQuite 420 Watts  For people who are waiting on theirs to arrive could rent mine in the mean time : https://www.miningrigrentals.com/rigs/3166 |

I made my pricing a lot more competitive, check it out using the link in the first post.

You can calculate the profitability of various coins on various websites. www.coinwarz.com is one of them. The link is already set so you can see the profitability of my A2, noting that these are no sure things, coin difficulty varies and sell prices vary. You can of course mine a scrypt coin that you believe will rise in value. multipools are an option as well. Multiply the daily BTC per MHs with 28 to get to the BTC estimate of my miner. Again this is an estimate, profitabilities cannot be predicted. Hope this helps. More questions just ask. EDIT: to answer you question, yes 24hr is .084 BTC, but you will receive an extra 2hr bonus for that. (which will make .0775 BTC for 24 hr) |

It is an A2Mini with a modified casing to improve cooling and reduce noise, with a BeQuiet PSU, running stable at 1280Mhz.
More improvements coming, when cooling paste and heat sinks come in.

Almost done with my custom casing. Just needs some finishing touches. Overview:  The fans:  The A2's:  And some lights to find it in the dark  :  Seems to hold the same temperatures, and a slightly lower Hash speed (I think that is due to a different coin mined on the multipool, clevermining) What do you guys think of the setup? Any improvements?? |

Hello! Is there any warranty for miners? Kindly, Muhammed Zakhir the Q&A on the website says this: 14 day to return to UK(shipping paid by customer ), 30 days return to China(shipping paid by customer) |

I wouldn't use that thermal paste if I were you unless you are very careful applying it. It is electrically conductive. I used Artic MX2 (about £10 for 30g), yes more expensive, but it is non-conductive.
Heatsinks look OK though.
I'm convinced though that better airflow across the units is the solution to the heat. Really need to check out reconfiguring the blade positions properly
I will take that into consideration thanks! edit: I haven't taken them apart yet but I can at least put it between the conductive sheet and the heat sink, no risk of shorting anything there. |

And now on the website we have:
"As of last week, manufacture has swithed factory and the new batch we received on Monday(9th June) had some issue with misplaced resistors , Manufacture decided to callback this batch, the shipped items are called back and requires some modifications on the miner. we will start shipping around next Tuesday (17th June)
This only affect the batch on 9th June, and A2BOX is manufactured in a different factory therefore not affected. "
Still no email from MinerEU.....
My email was replied within ours explaining my A2MINI was not among the 'defective' ones. But I am always very nice in my E-mails |
