Announcement: Bitmain launches AntMiner solution, 0.68 J/GH on chip

[reactor]

So we've got folks on board for running EU, AU, and US group buys to ease shipping on Bitmain - all we need is a U1.

Heeeeeeey Bitmain, any updates on the status of the hardware?  Figure out those problems yet?

We have produced a small batch of U1, and it can work now.
However the yield is not so good, and we are solving this problem.
Please wait several days again.
Thanks very much.

Since you appear to be posting for Bitmain...

Any chance they're going to discuss resale/group buy/respond to PM's/etc. any time soon?  Thanks for the update on the hardware, much appreciated, but some of us forum folks like to line our horses up so once the cart is ready we're set to go.

anyone have immersion cooling experience? Looking at the success of asicminer's efforts, it seems as though immersion cooling of antminer boards would not be difficult. A 12"x12"x10" tank could easily house 8-12 boards.

I will try the update. as of 14.5hrs operation for both units (Unit 1 has a v1 board and the v2 replacement board, unit 2 is v2) shows:

stat                 unit 1                     unit 2
GH/s avg           199                        204
rejected            218                         13
HW                   68,500                     10,800
DiffR                 28,000                     1,700

the rest of the stats were similar enough to be omitted. It seems fairly clear from the results at 14.5hrs of operation that there is roughly a 5GH/s difference in the units, probably a result of the different firmware. Temps on unit 2 are 49/50 while unit 1 is 51/54 - I will update the firmware shortly and may try pushing unit 2 to 425MHz

I updated the firmware, and there is no change to the hardware error rate. (Bitmain, is there a way to see which board or chip(s) are producing errors?)

stat                 unit 1                     unit 2
GH/s avg           200                        204
rejected            7                            8
HW                   23,500                    3,800
DiffR                 896                        1,024

also, i tried the 425Mhz code, and hashrate seemed to drop to around 187GH with more errors, so i guess temperature is a factor

Does anybody know where is temp sensor on the board?

Aw, come on. Can't they put a couple 6-pin pcie power sockets in place of the terminals?

Im split on the issue. most MOBOs that are ideal (cheap 600w, preferably modular) only have 2 pci connectors, usually running on the same 6 wires. this isnt enough for the sytem, meaning you still need either a higher-priced PSU or to chop up the ATX cable.
simplicity = cost

I have found that the BEST PSU for this is a corair 600M. Its modular and has pci cables (but the 2-on-1 type i just mentioned). But more importantly, it is single-rail offering over 550W on 12V. Even better, the 8-pin (2x4pin) AXT plug is a thick guage and easily cut up and split for use. I run 2x12V and 2xGND to each board, and the wires barely get warm. That means the only wiremess i have is 8 power wires that come from the PSU in 2x4wire ribbons, and the 24PIN ATX cable which is ziptied to a small bundle. The 4/8 pin ATX connectors seem to be a very reliable source of power and thick cables that dont heat up

Thanks klondike_bar!  I was just wondering which PSU I should be picking up for my miner!

Yes, the newer unit has a much lower number of stales. But HW of these two version are same.
If you care about the stale number of the old version, please try to update the firmware.
Download: https://github.com/AntMiner/AntGen1/tree/master/firmware

After upgrading the firmware of my both AntMiners from the older version to Nov 29 version and running a 12 hours+ mining test on the new firmware, there is a significant amount of stales less:

I would say it is getting better and better!

This is what I'm thinking....

This would have been really suck, if AntMiner sat in the lab during this whole time, trying to perfect every aspect of it while it has ability to mine

these minor issues can be dealt with while we have our miners in hand, working for us!

For the miner, PLEASE DO NOT go for the cheap PSU!!!

You will end up spending more $$$

Where do I buy those ANTMINER ASICs?

Is there a website or an auction?

Look in the Group Buy section... there is one going on right now

Bitmain just refunded my RMA costs. This is by far the best service i could have ever imagined in the bitcoin world. -Thanks BITMAIN

That's excellent to hear. Kudos to Bitmain!

I'd definitely buy some more units myself if a) there would be any for sale with the 'vouchers' due to participating in the very first two auctions and/or b) they'd come up with a "next generation" higher GH/s performing product. To tackle b) I could of course get multiple units more.. hmmm..

Warranty seems to be pretty good, too!  My Group Buy member was sent the replacement PCB via UPS

No Fuss about it.

Bitmain Likes to Thank the Early Product Supporters! Givingaway 1 AntMiner to a Lucky Buyer!!!

* 1 AntMiner purchase will enter you 1 ticket in to the total of 300 drawing pool.  After the final miner ships, the winner will be announced by Bitmain.

This was from Bitmain to the buyers in my Round 2 Group Buy...
