can we get clarification on whether these will have the PCIe connector for power?(new version units) ... or still just the old version where we gotta hack PSU cables? TY

they hosted by an rpi? if so... mine do that every once in a while, usually within 3 hours of fresh power up... if its gonna even happen. I find just moving USB cables around, fixes the problem more often then not ...
theres reports rpi cant handle many USB devices well...

what psu are you guys using?
so far i killed 2 psu any ideas what is going on?
You want to make sure that you arent using 2 PCIe connectors on a single cable, that is easily overload for just a single cable. I tried that for a few mins to see how hot those cables get w/ a 400w load and it was HOT! =P |

I wonder if these will be the newer ones w/ the PCIE connector directly on the blades or not..... hrm.... that would be nice =)

Thanks for making me feel bad.
Ha, all that really matters is they are hashing right? =) |

Just sent payment for 1 unit =) , no errors in order process, waiting for payment to confirm!

I think the advantage of the BTmine box is the fact it has a CASE.
Yeah, a case is nice, my avy B2 has sat out in the garage w/ windows open and rain has been flying all over the room due to wind... my avy is ... unaffected since july =) |

Well I have one box they said will ship out tomorrow - crossing my fingers!
When I get it I can provide pictures of it vs ANTMINER. Antminers are only about the dimensions of two power supplies and draw ~410W from the wall for 200GH. From the pics it is obvious BTMine's box is going to be massive in comparison. The power supplies included seem to be 600W and rather cheap (dual rail? ugh)... So that is why I figured any quality >50A supply would do (I've been buying Corsair 650W off eBay for $40 as I alluded to earlier) I also have a wattmeter and plan to get actual draw of the BTMine box as soon as it arrives...
Yeah, I want an antminer or 2 ... really bad, they look awesome but at 3btc ... cant justify the price vs these rigs unfortunately =/ Only benefit of antminer would be for people that pay tons in power costs I guess... |

This is absolutely fantastic! Meanwhile, anyone know how the ATM in VC is doing?
Noones stated anything after its first month worth of exchanges... Im interested in seeing how long term these projects are panning out... I mention this because same is my concern for retail places like overstock.com =)
I hope a decent steady stream of business is seen and not just a huge hype splash then nothing =/

just a heads up, I paid yesterday and via email hes claiming I paid today and that it will take 3-4 days before it will ship out. Disappointed I am.... since OP states 2 days shipping and stating I sent my payment today .. blatant lies.
Consider the time difference before you dismiss his statement about when you payed. Granted, it seems like they are struggling to make there shipments, but still. I doubt they are setting out to lie. Well, either way, expect 8 day delivery time frame now.... Id guesstimate. Ah, I see he updated the OP to reflect the delay... Price should be lowered a bit considering the delay. |

I added a bit of cooling to the side of each chili, so it blows air across the VRMs on top and bottom of board, I also have the exhaust from the heatsink deflected down onto the VRM section, using cardboard. I think the side cooling(implimented last night) has allowed a tad more speed, I really want to try heatsinks on bottom of board. Im waiting to see if I ever get them from the guy I bought this miner from...lol!  All but 1 of them run 37+GH @ an avg of about 55-60C... one of them is an oddball, 35.6GH @ 65C (tried reseating heatsink several times w/ no improvement) 3 of them run 38GH+ and one of them has been up to 40GH+ several times....wish I could stabilize it that high, but it clocks down. |

UPDATE: did get a response from seller, thank god! =) ... yay thanks man!

What temp is being pulled per device as the "lower temperature" in bfgminer? When I go to manage devices, it shows 2 temps, one obviously the highest temp chip, the other is lower, usually in the 30's
Also, Im wondering, when I stopped a device(one of my better ones that usually hashes at 38gh+, using the mining application) .. let it sit for a few minutes, then reenable it..
It slowly climbs up to its normal 38GH, then I saw it go over 40GH as the voltage climbed to 1.15v+ ... then it slowly started going down(both voltage and hashrate) .. back to is normal 38GH range, is this a temp threshold on the power circuitry being hit or OCP or something?
Im wondering if adding cooling to the power area would help it go higher than 38GH =P
Right now it is the general board temperature. That will be changed in the next FW revision to the temperature from the sensor right near the mosfets. It might, although some of that could also be due to a bunch of effects. When you first start things up the temps are lower. The chips draw less current when the temperature is lower, but as it starts heating up the current goes up. Not only that, but the traces on the substrate and in the chip itself get hotter and their resistance goes up, so your voltage drop increases for two reasons and the actual voltage you see on the silicon is lower. Since the frequency (and hashing speed) of the BFL chips is voltage dependent, all things being equal they will slow down as they heat up. Well whats interesting is its one of the cooler chilis I have yet hashes the fastest. At 40+ GH its only reaching 61C @ 1.15v+ ... when voltage comes down to 1.112v @ 38.4GH its right around 54C ...lol .. I would like to see it try to stay higher. |

no word from seller, where did he go? hes usually on this time of day .... argh, of course shit gets weird when I place an order...

Did you try using the PSU it came with? Someone said it worked with a standard PC power cord.
I just don't want my house burning down over some crypto lol
Take pics when you swap bc I didn't get the PSU lol
The ones that come w/ it are rated for 170-264v ... they probably wont work in a 110v socket =P |

have any USA orders arrived yet? Im considering buying one and want to verify seller reliability =) on another note: These are great miners, but Sushi please try to get the price down closer to 2.2-2.3btc. There are a number of Avalon sellers that are pricing 240Gh/s machines at 2.25 to 2.4 btc, or roughly $7.75/GH/s at current rates. At 3btc, the AntMiner is $12/GH/s overclocked, which is priced more than 50% above the competition.
Granted these AntMiner are more compact, quieter and more power efficient, but anything north of 2.3 btc would be a premium that is tough to justify. Not to mention the massive difficulty spike that is coming...
I wholeheartedly agree =) ... 2.5 would even be nice! |

Im confused, thread says "closed" ... but your website says you still have antminers in stock? What happens if I order one on the website? .. do you have them? When will it ship?
