A4 Dominator - Pre-Order Group Buy - 280mh, roughly 1000w, $1800 + shipping

[excelerator]

I just received an offer to purchase an A4 from a Inno reseller on Alibaba for shipment within 15-20 days. The price was $2400, including a power supply, and shipping was extra.  

That's an excellent development in that Inno now appears to be making promises to resellers of the A4 for availability.  The two resellers I've been in contact with previously would not take pre-order money for the A4.

It will be interesting to see what they provide in the form of bulk discounts for larger operations.

Looks like you can get them in quantity for $1990 with 3 day shipping after payment.

I just got a quote for 4.

Nice find! This reseller appears to accept Visa so further derisks the purchase.

 I'd be VERY worried about a reseller that has the R4 listed for sale at $1100, as that's a good bit less then BitMain's inflated pricing on those units.

 The pictures also don't match Innosilicon's stated dimensions for the unit, though they DO match up with some of the recent pictures that have been posted.

[Ilan123]

I have been speaking to Amanda Zheng on Alibaba.com she said that, Innosilicon is making the chip and they are making the hash board, main board and whole unit. She has said that there will be a max of 200 units dispatched in Batch 1 and their price to ship an individual unit on Oct 15th is $2100 + shipping. The Co name is Shenzhen bit-winkor Electronics.

She said that I would have to wait until Batch 2 ships in December to get the price of $1800 + Shipping. She has sent some more pictures.

So what kind of warranty, if any, are they offering? The seller shows to have an onsite assessment done but they haven't done many transactions on Alibaba in last 6 months.

I am not too sure about warranty I'll ask her and will report back

Anyone got them yet?

Ok, if these pics are real then I have some serious concerns about pumping 1100w through what appears to be 4 PCIE connectors!  That just is not going to work.

Also looks like they are getting 273mh from almost 1100w.  This means the Titans are clearly very competitive and the A4's will have nothing in this first batch on the Titans. 

I hope I am misreading the power and connector situation because those plugs are not designed to handle that kind of load.

Avalon 6 pushes 1100 watts on 4 PCIE connectors no problem.

[Longsnowsm]

I think the rated spec for those PCIE plugs is only like 200 watts if I recall correctly.  And with the power consumption coming in so high the A4 certainly isn't going to be "Dominating" the Titan's.  I have to admit I am a little disappointed and concerned here.

What I don't like is blowing all that heat directly on the power connectors.

Seems like there has to be a better way of designing that...

I think I've worked it out, or at least I hope I have. They're fully modular like the Farmboy with each unit only having 2 cards (40 A4 chips each) or 40 x 3.5 = 140 Mhs nominal output. It would be really hard to squeeze 4 cards into that 130mm square extrusion given the cooling required for 1100W. If you could, you'd need left-hand and right-hand cards to install them back to back. The good news is that it looks like they have heat sinks on both sides of the cards and a single fan per unit.

As in the earlier pictures each card has 2 x 6pin PCIe connectors for 300w max available per card. It looks like there's another set of 10 pin connectors between each card and the Raspberry Pi controller which is a standalone unit in the picture above. (it's definitely not connected to one of these A4 units).

My only concern now is the power supply for the raspberry Pi. I hope it's PCIe 6pin because I've already ordered my power supplies based on the specs we were given and assurances from Inno once I'd ordered that they would only need 8 x 6pin. I asked about 20+4 ATX and 4pin 12v but was assured 8 x 6pin PCIe was the only requirement. Thankfully I've got 1500w 10 x 6pin PSU's on the way so have 2 extra connectors I can mod if I need to.

Last thought. 200 Max in batch 1.
No chance. Keep in mind that they were looking for 5 investors with up to 1M each and were promising chips at $12ea initially.

More good news is that it looks like you can run 3 per Raspeberry pi. There's 6 10pin connectors and they quote 550w, 1100w, and 1650w configurations. Well that's what I think it says ;-)

They just came back to me on the Warranty she said it was for 1 year which is pretty good compared with Bitmain

the same seller is also offering a 300mh a4 for $1000 @ 800w
something is not right there

It's a picture of Baikal miner 900 MH/s)

Are there many people who ordered A4 miner?

Hmmm definitely something not right there as you say, very curious, perhaps they are a hoax seller trying to cash in on the back of it all?? Glad I didn't follow though with an order.

That is the intake side and the fan exhausts the heat out of the "front".

Ok, so maybe we are talking about 2 units to make up the 273mh 1100w miner... That would make sense in light of the first picture showing 1 miner on top and 550w, and the 2 miners/cubes on bottom at 1045w.  So possibly 2 cubes to make up the 4 blades we were quoted in the original description as it appears there are only 2 blades per cube.  So that would make sense if that is the case.

No this would be a HUGE deal killer if you needed 2 units because the price quoted is for one unit

Ok, So I received an update from Inno regarding the A4.  They are running a little behind schedule.  Here is what they sent me and we have some pictures if I can figure out how to post them here.  Overall this isn't too terribly unexpected, and I am asking for more details regarding the miner, the better than expected performance etc.  I will post more as soon as I hear more from Inno.

I have a good news and bad news about A4.
 
Good news is that the mass production of A4 wafers went smoothly and the performance is even better than we expected. Bad news is that the Assembly house was not prepared enough to meet our schedule, and the qualification took a little longer. Fortunately the issue was solved and the condition is still under control. Currently we have some sample miners ready. Attached are pictures of our sample miner.
 
The estimated shipping date is Oct 15th due to the National holiday from Oct 1st to 7th.
 
From a design of ASIC to a complete miner, there are many processes to go. Unexpected things may happen in each process and that's why we declared one month delay. For now most processes went well, and our sample miners’ performance is beyond our expectation. All we want is to select the most profitable yet reliable solution for our customers.
 
Really hope that you can understand and give us more patience.
