As always excellent review. I will note the same as MrPark. The company should be avoided. Their hardware is deceptively advertised at rates higher than the hardware actually goes. The webUI reports inaccurately 1.27 all the time regardless of the pool rate despite the other numbers being refreshed. Leads me to think its a false hashrate. I don't see this with any other miner product. It's just another case of smoke and mirrors with Joshua Zipkin deceiving people. Also should be noted that ssh access is possible BUT sadly they don't provide that info or they lie about the logins. It required some hacking the image to actually get SSH working properly in my case.
FYI the SAME model is reported on their site as 1.3Ths. So again more lies from this company. AVOID!! Oh and according to them, I am their official support contact. I am not. They passed the buck off to me. And I am trying to get Joshua Zipkin arrested for putting my family in danger. That should speak volumes about the company itself. Considering he thought it was a terrible idea to send a review unit initially to dogie, find it hilarious he took my idea and ran with it. I will post the chat log later where that comes up
Agree 100% with Opieum and Mr. Park: Avoid AMTproducts/services!!
I too finally got my miner. Despite assurances from Joshua Zipkin in
MY Skype chat room (I'm customer2 there) that mine was one of ones shipping *with* a psu, it of course arrived without one...
On mine all 3 fans had their wires cut leaving about a 1" stub from the fans. Long 3-wire cables were connected to the stubs and ran to the controller board, plugged in there and hot glued as well. Those turbine fans are definite pulls from salvaged servers.
Mine as well was filthy and obviously ran for more than 'a few days and the rooms are really dusty' as Josh replied when I pressed him about it. Josh, remember that I build industrial equipment? I have gear in places from clean rooms to absolutely horrid metal foundry conditions. I know dirt buildup rates. Not only the fans and insides of the case covered in fine dust but even on the ends of the heatsinks in back where vortexes form had long term build up. As in growths about 2mm thick...
Since my miner arrived without a psu I had time to kill until one arrived (a week later - I got Lucky!) so cleaned it up and replaced all 3 fans with ones from Bgear. Also added a cover directly over the top of the row of hash board heat sinks to channel all airflow from the fans through/over the heatsinks. Works quite well.
I will say kudos on the heatsinks: Both the main bottom ones and the top sinks are 1st rate and well done, even have tapered fins with further tiny fins on them for great efficiency. Beats the hell out of the massive bulk-extruded ones from the 1st try versions.. Then again, Innosilicon had plenty of time to observe the screwups from Bitmine.ch/AMT and a couple other companies betting on the A1 chip as they floundered with a horrible thermal and PD layout. Inno saw the obvious flaws with the original thermal and power layouts and Got It Right. Yes, they then released the new and IMHO far superior board design for folks to make boards and miner using their chips.
My miner album warts and all:
http://imgur.com/a/DmzAvHashrate reported on the web gui is always 1.2th. Never ever changes like my Ants do. However - again I got Lucky: My pool consistently reports 980ghs-1.2ths as the swing and pretty much a solid hair over 1th as average.
Damn - should have gone to the Casino that week... Actually finally got a miner from AMT (6 months late), actually got a psu from them for it, it runs per-spec speed and, after cleaning out the dirt it looks pretty rad with the Bgear fans...
