What were you told for Avalon pricing? I might be interested in their next chip in a few months, but the pricing versus performance on the 3222 isn't really gonna cut it. By the time we'd have miner to market the chip would be almost a year old and 1.5 generations behind.
I'm looking at getting a thousand of BM1384 at the start, and was told [redacted out of courtesy for Bitmain]. Bulk availability I'm told MOQ of 25 wafers, minimum two month lead time, wasn't given a price.

I have no problem teaming up on discounted chips, especially if the end result is home miners get two more decent machines on the market and the net cost to them is reduced.

I need to check on my hom desktop for the Price of A3222 I will pm you as soon as I have it. (around 5$ if my memory is good)
Its not awesome but I guess maybe we could get a better price if we buy bigger quantity. Janet also told me the same about MOQ.

We could check that via PM or skype.

Although this isn't a proven chip, apparently SFARDS (which used to be Gridseed) is launching a new miner that could be interesting.  They state they are planning to launch their miner in April, and chip specs sound promising.  Not sure if you saw this thread:

Might be worth looking into, but when I saw their tapeout announcement I wondered how likely it was they'd have chips in April, let alone a deliverable product. Also, we don't really care about scrypt at all.

as of now, 25 wafer can ship as in-stock without the 2-month lead time.  May be something was lost in the translation.

Janet told me that 1000 chips could ship from stock, but that in general all chips were set aside for miners under construction already. Yoshi did not say anything about wafer orders, just also that 1000 chips could ship from stock and to contact Janet for purchasing.

Every time I've asked for protocol details I was told to just look at the code for the U3 and such. Everything appears to be standard UART comms so it's probably all implemented in cgminer drivers anyway. I think the only real tricks would be fan speed and temp sensor interfacing, and core voltage adjustment. But code is Novak's job, so I can't really say anything for sure.

Sidehack,

Yoshi got your message about your specific order quantity and got you going with the order process moving with Janet with even a special discount on a smaller chip count. (The price you listed here is lower than what is on the price sheet  Wink )

if you need 25wafers, they can be shipped in 2 business days after the payment, however, price be different from in-stock shipping vs 2-month lead time version.  Wafer has to be ordered then they have to be packaged and it takes time.

And the new chips for the summer will be a fantastic one, but please wait for the official announcement regarding those items.

Righto. The price Janet gave me on 1000 was actually about 20% lower than what Yoshi said, which I'm certainly not going to complain about. What would pricing and availability be like for 10,000 chips? We're trying to figure out a good timeline for things. We're sending off for prototype breakout boards today, and later this week I'll be working on a stick miner design which we'll modify as necessary once we have breakout boards in hand to test chip functions. 1000 chips would be okay for a stick miner batch, but as the primary goal is a larger (18-chip) board which hopefully would be designed and prototyped within a few weeks after the breakout boards are here, it'd be nice to know if we could get a large batch of chips to run out a large batch of full boards within the next month or two.

If you need to message me and keep some of the numbers out of the public eye that's fine. I'd just like to get an idea of what's possible.

you may want to reach out to Yoshi and get the NDA signed for further pricing on more quantity and availability info

I've been talking to your people for a couple weeks and that's literally the first time anything NDA has been mentioned. I'll get back to him about that I reckon.

I'd like to go ahead and say thanks to bitmain for their support of this project; between Janet, Yoshi, and Bitmain Warranty, we've had three separate people from bitmain making sure that we had the info we needed on chip availability/prices.   It's pretty encouraging to see that kind of support for this project.

Just to chime in, your stance about this is getting you +1s everywhere Smiley

Really, Bitmain, you're rocking the shit out of every other manufacturer.

So because we're cheapskates and buying 10 half-sized one-chip breakout board prototypes is a fair bit cheaper than five two-chip breakout board prototypes, it looks like we're buying 10 half-sized one-chip breakout board prototypes.



Novak's trying to push the order through right now. I'm gonna start on a bit of actual stickminer design tonight since I have other things to do that'll take a lot longer than one hour but quitting time is in one hour. I'm really looking forward to getting this thing moving and playing with some chips.

Sorry if i misunderstood... but is still the plan to sell breakout boards with the chip, or will they come bare without compos?

None of the above. We're not selling breakout boards, nor have we ever stated an intent to do so. We're making them for in-house use for testing and prototyping. If enough folks are interested in playing with BM1384 themselves, and if the boards work as intended, I can release the design files so folks can make their own.

We will not be selling breakout boards. We will not be selling chips. We will be selling complete miners only. I'm just keeping people updated on progress, since this is a project discussion thread.

It's quitting time now, but I was just looking at ~8A buck chips for those crazy people that want to crank their stickminers up to 5W output (or more). We sent off for the breakout board PCBs and I expect to have them in hand hopefully end of next week; I want to have an initial stickminer PCB already done by then. I probably won't get any work done on this tomorrow on account of I'm way behind on a router setup I owe a guy, and maintenance on our own hosting network.

Also, tentative stickminer model names are Compac (single chip) and Amita (two-chip). Likely we'll shoot for a green heatsink, top-mounted if possible.
