"Sorry to inform you that we don't have spare chip to sell. Please kindly consider the miners directly."
- Bitmain

"I do not want the miners Bitmain is currently offering for sale. I'm working on a design for a miner which meets needs your machines do not. One of the businesses I am working with is currently using S3 and S5 boards on C1 waterblocks for both residential and industrial heating applications and would like to continue using these installations with upgraded electronics, but your new S7 does not meet the mechanical specs (in addition to other system requirements) to be used. The board I am designing will do the job. I would like to use your BM1385 chips, as I had a fair amount of success working with the BM1384 chips I purchased earlier this year. Your chips are good and I was very glad to see the design improvements from the previous generation, both in efficiency and ease of interfacing. If I can't purchase sample chips from you, which will lead to a final design and likely mean factory batch orders of chips purchased from you in the next several months, well I'll have to buy someone else's chips instead.

Would Bitmain rather have me and the groups I'm working with as customers, or would they rather see us purchase from Bitmain's competitors?

I am right now designing around the BM1384 and intend to retool the final design when new chips are available (from Bitmain or someone else). Having chips in the near future would be nice, but I could wait about four weeks (when your S7 is supposed to start shipping) without causing any real delays. I would be willing to pay up to US$200 for fifty BM1385 shipped to my shop in the US. This is less than one S7 board worth of chips."

It's probably some CSR whose primary job is to make sales. Even when I was asking about BM1384 the first half-dozen emails they tried to sell me S5 instead. They've been trying to sell me S7 since before the S7 existed - I think in May I was told instead of buying more BM1384 I should just wait until the S7 comes out in several months. That's the job, sell the product not the parts. They get more money that way. I want to convince them that I would be servicing customers who either would not or could not buy their products, so by selling me the parts they get a piece of the pie instead of no pie at all.

I'd say it's more like like trying to sell me the full V8 when I want to build a 4-cylinder and all I need are the pistons.

well that sucks.

maybe I can send a s-7 board when they come.

lowers my machine from 1200 to 800 watts and gives you chips.

Just a thought.

Someone else has already offered to do that. I'd rather not, and certainly not if Bitmain isn't willing to sell batches even if I get a final working design with used chips.

I was very interested in the s7 but at that price its not possible for me and even if I had the funds I'm sure I wouldn't be a 100% on it anyways. The efficiency is nice but not worth the premium on this big of a unit considering the difficulty will increase and the halving is around the corner. I guess I am just going to continue to mine on my s3s and s5 till they die, or if someone else comes out with a equal or better product and they start a price war with bitmain. I would still be interested in 1384 upgrade boards for the s1 s3 s5 style heat sinks, all I care about is my total wattage used on my electric bill because I will continue to mine with what ever gear I have even it it isn't making a profit upfront (sub 1w/1ghs). the s7 was one of the reasons I haven't purchased some of your sticks because I don't have much btc, hell I have 30 1384 chips that I took off a bad s5 board to mess with when I have time.

I very likely won't make a 1385 stick, unless I get demand for at least about 500 of them upfront and then it'd pretty much be a straight modification of the Compac. I'd rather focus on 4-chip-pod dev because that'll lead into 30-chip TypeZero dev pretty directly. I got so hung up making the stickminer into a viable and functional product that I ended up losing a lot of time. If I'd skipped it and gone right into large board dev I'd probably have had a working BM1384 S1-sized board two months ago. Course in a way I'm glad I didn't, since it would have been a half-size board instead of full-size. Full-size board I think is becoming a better plan given that's what dimensions we're leaning toward for the standard rack case blade. The S1 and rack were originally going to be two different products.

If not from Bitmain, maybe Canaan-Creative or InnoSilicon. Someone's gotta take care of the 99%, right?

You know, when I was asking about 1384 they asked me if I'd rather not buy a bunch of discounted U3 and take chips off them instead - until I reminded them that the U3 had 1382 on it and that wouldn't do me any good.

I meant like a few one off prototypes aside from the boards (if you had a few odd chips out after the boards) if you were even gonna toy with the idea of 1385 but I don't blame you for not wanting to take a board apart to make a design in case they never sell the chips then its just wasted time and materials because you would be forced to use another chip which means a ground up design.

Omg! That's so dumbass of them, they didn't even know their product!

I think Bitmain has a King-of-the-hill syndrome atm, here hoping they get their ground shaken by someone of the likes of LKETC (did i spell it right?) or SP-tech.

If I can get access to a full batch of chips (you know, something like 100K) I'd probably go ahead and make a couple hundred new-version Compacs just for kicks. Make a nice round number of full-size boards and then stickminer the odds-and-ends chips. Could be fun.

We need the idea of By Miners For the Miners....... they make a ton off their hosting, their miners, selling coin when the price goes up....ect. Its like the gold rush, the people selling the shovels and pick axes made out where as a few of the miners actually got rich off the gold. In this case its worse because they mine for themselves, host for other people (they make out in the end anyways), and selling their gear.

This is also the first odd chip, so it makes me think there was a 1381 and1383 as well. So maybe the gear pricing offsets their failed attempts or they had more in house gear than they let to light or sold to private ventures.

I believe they will sell this 1385 to sidehack but not until the s-7 has shipped.

Look at it from their viewpoint if they sell it now and sidehack can get gear out to the public it would hurt their bottom line.  They want more lead time.

  So if they tell sidehack today yes we wiil sell them to you  on OCT 1.  It will hurt s-7 sales. I do not think they will offer the chips until OCT and I do not think they will answer yes until very late Sept.

Business wise it makes more sense for them to do it that way.

If sidehack and novac keep sending emails to them along with miners like myself they will sell him some.

I purchased 2 s-7's today to show bitmaintech that
 A) I will support them
 B) I can donate a board to side hack
C) 10 people can donate a board to sidehack
D) 1000 people can send  an S-7 board to sidehack for mod's and or reworking.

I know the s-7 is too loud for a home miner.  But a 2 board s-7 with fan mods should be okay.

A reworked S-7 board in bulk could be viable.

Not the same as a universal rack/miner but flexible thinking can work.

How about I send a working s-7 to sidehack and have  it put in a better casing. same boards but cooled better and spread into a 4u rack. Possible down clock and under volt   and the rebuilt piece does 4000 gh at 800 watts.

or 3800 gh at 750 watts 6 fans  with better heat sinks .   3 boards turned 90 degrees better heatsinks on each side.  much better power efficiency .

what would that mod cost?

Well, you could buy 20 odd A3222's (the 25GH/s 0.4-0.6J/Gh things) off avalon themselves for 0.72btc. now, unless they are lying about having 9 stacks of 20 chips for sale at their store..
unless you're waiting for their new-bute hot out of the silicon oven chips (which i haven kept up with whats in r&d since the a3222 release earlier this year)?

as for InnoSilicon, isn't the A1, A2 and the upcoming A3 all S-crypt? what is this "A1 CoinCraft"? am i missing something?

little googling found out the Coincraft A1/A1 Booster is bitmines re-branded chip from innosilicon, but going by their site, A1 is a S-Crypt ASIC. so what is the A3 going to cover?

I think it's fantastic that people are making offers like this to move the project along, however IMHO unless sidehack can get chips in volume the project will go nowhere. Any mods and improvements based round an S7 hash board will fall far short of what he can make with a bespoke design and the Home Miner as the target user.

The single most important, nay essential feature being easy software controlled voltage adjustment so that after BTC halving people can match voltage to frequency and remain profitable. With the S7 board this will only be possible by reducing the supply voltage with all the problems that brings.

In the short term / if chips are never made available I still think the best solution is for people to make 3 two board miners from 2 S7, then use an S5 controller board on the 3rd unit. That combined with some good ideas / breakthroughs on how to adjust some models of server PSU down to 9V.

What about making a mod of the S7 that uses just one board and comes with a new "case" and Pi controller? I bet that would sell.

Edit, I think Rich was talking about the same thing sort of.
