Well this thread has certainly become interesting....
I want to buy LA30M (30Mh/s) Miner.
The forum price lists $3500USD, the website lists $4000 USD. I've asked about shipping and the LA30M is supposed to ship 3 days after payment. So if I buy today, My unit should be shipped by the 11th of May. I'm willing to buy at $3500 with shipping in 3 days.
I understand the BTC payment address is: 1DEBCZxfb8JRSf9oFk26oTJhHExedZ52nh (taken from the first post of this thread)
@asiabtc OR lightningasic, please confirm the current amount of BTC to send (here in the thread) and I will send. I'll then post the TXid's of my payments so all can see.

@ BITMAIN.... Bring back the days of shipping early!!
|

I'm in for two of the batch 4 units... I'm hoping/praying/wishing for early shipment by Bitmain (remember the good old days?)
This is a little more pricey than the S1 solution, but the reduced equipment footprint and reduced power requirements were enough to sway me in my purchasing decision.
May 8th seems like an eternity from now, and the new S1 price looks good but May 4th is 1/2 of an eternity (and I just bought 18 of the S1's at .6something)
For current holders of the S2, how many PCI-e 6 or 8 pin connectors are required if a power supply change out is needed?

I received an e-mail stating item shipped and my order status on the website now shows fulfilled (but no tracking info). For those of you who received tracking numbers did it come from a separate e-mail?

Ordered one from the website... we'll see how this goes.

Been off of the grid for a few months...
My order #399 was cancelled and refunded. Glad to have gotten out when I did.

Ordered one of these 1/7, received today in good shape.
Funny to see on tracking it left Hong Kong at 9pm, arriving in USA 9am the same day.
No damage inside the unit, no loose cables, no broken caps, no bent corners. I took it apart to inspect it, there were no "fuse" labels silk screened on the ASIC boards, however there ARE 2 fuses in parallel at that location, they are marked P. A Google search shows that these are most likely 32volt 3amp fuses. There were some loose/cross-threaded screws holding the ASIC boards on the heatsinks and a loose wifi antenna to adjust and tighten. I added some cardboard and masking tape around the intake and exhaust fans to direct more air through the heatsinks, also taped the gap between the two heatsinks to make a sealed tunnel. Along the edge where the heatsinks are screwed to case I applied some thermal paste to try and increase heat dissipation. The fans start at full screaming loud speed at power up, but quickly quiet down to a normal "gaming computer with lots of fans" level. Reported temps stay in the mid 30s C. One of the fan cables connected to the TP-LINK board has had 12v and ground cut off at the connector, leaving the speed sense and PWM wires connected. The red and black fan power wires are soldered to the power board, presumably the TP-LINK cannot provide enough current to run 2 the large high speed fans. Both fans still slow to a lower noise level after booting up.
Btmine posted in an earlier post that the unit could run on a single power supply, this is not true. I tried with a single EVGA 1000watt 80+platinum power supply (12v 83amp single rail), with the 24 pin ATX motherboard connector in ATX_24P and nothing in the second ATX_24P_2 connector. The unit would power up but only use the 2nd blade, running at ~100GHS. Connecting a 2nd 750watt power supply to the ATX_24P_2 connector powered up both blades, it is now running at ~220GHS. If I were to splice up a 24 pin ATX motherboard power connector splitter and connect both connectors to a single power supply it would probably work, perhaps I will try it later.
1400Mhz seems to be the limit for these boards, at first they ran for a couple of hours at 1500Mhz but then became unstable, the unit seemed to be rebooting and spinning the fans up to full speed then back to normal over and over, speeds dropped to less than 150GHS. 1600Mhz was even worse, many of the match_work_count units on the api log page were hashing at very low levels. Everything was normal after switching back to 1400Mhz (~210-220GHS).
The way to run with one PSU is by someway getting a second 24pin connected to that PSU. That is what people keep asking. One would probably have to buy a 24pin splitter http://www.ebay.com/itm/NEW-EPS-24-PIN-OR-ATX-24-PIN-Y-SPLITTER-POWER-CABLE-10-MADE-IN-USA-/251052154981I tried single PSU as well and it didn't work. Why: The power cable going to the blades (the white and black wires) are all +12V, there is one single wire on the blade power plug which is red in color and provides +3.3V. Each EPS 24 connector provides the +3.3V to the red wire (one for each blade). Figure out a way to get 3.3V on the second red wire without the second EPS 24 connected (a jumper wire soldered between the two perhaps?) with sufficient amperage, and you're up and running on a single power supply. Obvious, but for clarity, (You'll still need to fill all the PCI-E and 8Pin CPU connectors for the other blade) |

I was the 2nd peson in this thread to make a purchase using BTC as a payment. After a slight mix-up, I was able to narrow down a shipping date of the 17th. It is now the 18th, and I have yet to hear from Bit-Tech on any shipping data.
I really hope this is a legitimate outfit, but the sparse communications and the mix-up I encountered has me wondering.
To others considering purchasing here. I would hold off until the earliest customers report receiving miners without issue.
If my situation changes, I will post here immediately. -- Be wary.

--avalon-options 115200:24:10:D:1500:55 from the command prompt.
These ship set to --avalon-options 115200:16:D:1400:55 (1400Mhz) if you set --avalon-options 115200:16:D:1500:55 (You're overclocking from stock by 100 Mhz) ****** The values are baud : miners : asic count : timeout : frequency : technology. ****** From the CGminer ASIC-Readme file. Baud: The device is pretty much hard coded to emulate 115200 baud so you shouldn't change this Miners: Most Avalons are 3 module devices, which come to 24 miners. 4 module devices would use 32 here. (Our devices are 2 module devices = 16 miners) Asic count: Virtually all have 10, so don't change this. Timeout: A value of 'd' means cgminer will calculate it for you based on the frequency and is highly recommended. Frequency: This is the clock speed of the devices. For Avalon 110nm devices, values from 256 upwards are valid with the default being 282 and the maximum practical being approximately 350. For 55nm devices values from 1000-2000 are valid with 1500 being the default. (Ours shipped @ 1400) Technology: What sized technology ASICs are in use in the avalon, choices are 55 or 110, corresponding to the nm technology chips in use. (we have 55nm chips) |

Thanks, I will try that. The fpga control board is version 1.6.1 and the light near the done marking is solid red. Red probably means bad but does anyone know specifically what it indicates?
According to Avalon wiki https://en.bitcoin.it/wiki/Avalon#V1.61Red light = PSU issue. |

@Profmac, these units are 55nm Avalon chips, not 110, normal frequency is 1300-1400Mhz
@MValley, have you opened the case? If so, you can try running the unit direct by connecting the controller board's usb connection to a host pc or laptop and running cgminer 3.9.0 or better with avalon-options 115200:16:10:D:1400:55 set in the cgminer script or batch file.

Beat me to it, but I was going to say check reply #101 in the referenced thread, apparently the factory invoices and GB coordinator has no control of price (and the most recent potential customer was invoiced over $2400) |

Wow they at least closed it.
Looks like these units are going for below 2 btc now with no PS.
Reference? |

Arrived and spent most of the evening trying to get it to work. One module is hashing away and the other is none responsive. Installed new PSUs 750w each. The non-responsive one does not seem to be turning on the second PSU at all. The good one draws 450w at the wall. I might try shorting the 4th and 5th plugs in the 24pin to see if that will get the second module working.
Overall, it was okay to setup, it's really compact. It reminds me more of one of those Avalon minis. I will post some pics tomorrow.
Edit: if anyone could use the 220v PSUs, let me know. I have no use for them at the present.
We saw the same thing.... one side not firing up.... if you open the case one power supply goes directly to the board which contains the USB connection to the TP-Link. Fire this side up first, once it is up and running (Fan spinning), start the other side with the slaved board. Check the ribbon cables for good connections beforehand. I intend to see if I can get the whole unit running off of a single 1350W power supply this weekend. |
