Looking for B8 Coupon if anyone still has

I have 2 batch 8 arriving on Monday. You may recall that the controller died on my batch 1. That was 3 weeks ago. Teh replacemnt should  arrive by the end of next week.

I got some long data cables from Finsky. So, I can run both batch 8s off one controller.


Here's a dumb question:

Would it be safe to take a controller off a batch 8 and put on my batch 1...if i set the frequency back to 600?

different software and different design...might be incompatible.

+1. Thought so too...always good to get a 2nd opinion. Smiley



I test today B8 firmware on B5 antminer and works, but 3.3 thash @ 700mhz. I down Speed to 600mhz and still works 3.3 thash. You can use B8 controller with B3 or B5 software and with B3 or B5 hashing boards without problems. I guarantee.

BUT today i test 2 antminers batch 5 conected on the same controller, and flash with B8 firmware for test and only show 3 of 6 hashing boards (6 hashing boards detected with B3 & B5 firmware around 9.7 thash).

I don't know if batch 8 can be dual Mode like my B3 and B5...

Batch 8 at fixed price
3.1 BTC with shipping from stock
Finally a good deal
Ordering 4 of these beauties

I noticed.  I was probably the first one to buy.  I've been refreshing the webpage every 2 to 5 minutes since they were down.  The moment it came on line, I bought 23 of them.  I wish my other BTC was available on CoinBase so I could have bought more.  Oh well...

EDIT:  9 x S7's will have to sit on the sidelines until I get my power upgraded within the next two weeks.  That's if they arrive before my power is upgraded.

judging by the gigantic difficulty jump, they produced a lot of them and are unlikely to run out soon.


Anybody got a coupon they don't plan to use? Let me know.

The S3+ went into the "teens" in number of batches.  I first started mining at batch 8 of the S3+.  I first began research into whether I wanted to start mining at batch 2 of the S3.  The S3 went to at least batch 15 if I'm not mistaken.  Then the S4's came out.

Love my remaining batch 2 S3. It's pounded away at 440- 500 GHS since July 2014. I overclock it to the max in the winter. Smiley

LKTec announced a 5 THS rig at 1000 watts.  Last I heard, it won't be available until late Q1.

I haven't seen anything about it lately. Maybe they scrapped the plan?  0.2 w/ghs in Q1 might be too little too late?

If you have 5c electricity even with a doubling of the Difficulty & the Halving a S7 will still be making Money. Beyond that there is still plenty of scope for a better Miner. I think a full custom 14nm ASIC would after the halving put profitability back where it is now. The bigger issue / unknown is I think the exchange rate staying where it is / improving further?



I really hope your right. I pray and expect to keep mining at a profit because I genuinely enjoy mining coins over buying them.

When it comes to 14nm and other advances upping profitability I think its a race to the bottom but one thing is for sure, well see soon enough.

I do hope manufactures like Bitmain and Avalon (Is there anyone else for home miners?) stop selling at some point soon to keep these 15%-20% jumps from happening. If I see too many more I'm selling all my gear and shutting down for good. I bet you will too.

However,

One, they never really went above this many batches of a given generation right? They always take a long(~6 month) break.

I  think the number of batches we have had is a special case and a direct consequence of the problems they had with the first batches of S7 which required  a 12V + supply voltage. I think they were selecting BM1385 / Hash Boards and Batching them up to keep things going while they iterated the design, reduced the string length and added what I still assume to be a Buck Converter.

Two, won't it just ruin the market for good. I'd think that they may want to do what they did last time and cut us off now while the mining ecosystem was still in good shape, so they will still have an eager market the next go around. Why kill the golden goose now. I'd say a strong new release just before the halving with a break from massive diff increases Jan-June is just what miners need to stay interested in mining whatsoever.

I think we are  beyond Bitmain having that sort of control on the Marketplace, installed base and other suppliers are now just too large. I think they will sell as many as they can make.

Otherwise I just don't see mining being even slightly profitable again. And without profits, miners won't be able or be interested to buy new gear in 6 months, or ever again for that matter.

I would expect there to be plenty more until the next Miner is ready?


Now that I re-read that I think you may be right, they never state that this is the last BATCH.

If this really is the last batch and they limit it to a reasonable number of units I think these will hold up ok honestly.


Not quite sure why you think this might be the last batch? If you are referring to.

4.73th/s is the final version of S7 which is more stable

Then it could mean final batch but I read it as meaning they have stopped messing with the design and have stabilised on the 135 Chip 700MHz, 4.73TH/s version? I would expect there to be plenty more until the next Miner is ready?

Funny to see bitmain swap the price again from USD to BTC moments before the BTC price starts dropping...... Cheesy Cheesy

If not then mining is done, ruined, for good possibly. A few more 15-20% raises and NOBODY will be making money mining anymore. Good for the coin price, end of the road for miners. We all will be mining at cost just trying to recoup the investment within a year and that means a lot more bag holders for sure.

I think honestly this is what some of the big boys want. If mining becomes this expensive it will drive the value of their extensive coin holdings up and up. Despite the fact that they might even be mining at a loss they will be driving up the price of their tens of thousands of coins. There is some really complex economics behind this and I tried to make some formulas to encompass it all but there are too many variables.

Oh and I forgot that Avalon is the wild card here because all they have to do is over-manufacture a few tens of thousands of units and everything goes to hell anyways. They can sell them for dirt cheap, or just mine in their giant farms. If either Bitmain or Avalon manufacture too many units its disaster for whoever is reading this right now.  Tongue

'The right to privacy matters'
Anyone have a coupon for s-7's  my bitmaintech name is philipma1957 same as here.

It is a bit frustrating that I was never compensated for a slow 4500gh batch 1 machine   and a slow delivery of my batch 2 machine.

I purchased 5 S-7's from bitmaintech and 1 from lee to be hosted in china

of the 5 direct from bitmaintech  4 hash well 1 hashes poorly 1 was delivered late.

A coupon would be the correct  thing for them to do, but nothing.

If anyone has a coupon for me you can pm.  thanks phil

Hello, today bitmaintech release a new firmwwre.

I test on a B3 and B5 solo and 0 errors for 2 hours mining.

But test in duo Mode (2x B3 and 2 B5 in one controller) and don't recognize more than 3 hashing boards.

Algo test some overclock and stable without HW error @ 650 mhz but maximun 5 thash Speed.

Thanks for the info.  I won't be upgrading.  What's the date on the firmware?

EDIT:  Never mind... I see it's December 11
