Same issues. Mine is not even working with AntPool. Showing not hash speed.

Miner arrived today.... i have BIG problem with configuration... seems working only with antpool.... the miner is alive but in my antpool configuration my worker is offline... Nicehash dead Suprnova Dead dwarfpool dead...  someone have got a good configuration? what is wrong??
Thank you very much.

check this video... this dude has it setup. You'll have to pause the video where he shows his config screen

Can someone share their configs for their E3 for antpool or nanopool (or both)?

How quiet is this thing compared to the S9?  The youtube video seems not as loud once it past the boot sequence.

Impressive. RX 460/560 or GTX 1050ti's can match it in terms of electrical efficiency, Regular old RX 570's would better them in component efficiency but nothing matches it in price (atleast for the batch 1).
I honestly believed they would be using off the shelf GPU's and have a product similar to the original MXM GPU based Pandaminer ... I am surprised they designed their own chip entirely - would be interesting to know if it was made by TSMC at 14nm.

I see that there are three boards with 6 GPU-like cards on each for a total of 18 cards each having its own 4GB DDR3 bank.
Thats a staggering 72GB DDR3 just like the rumors stated - 7 RX 570's can manage the same hashrate with 28GB memory.

What I find curious is that even though there are 18 boards, the UI shows 9 Chains each doing 22-25mh - so 2 of the GPU-like cards are somehow being shows as a single unit and individually are doing ~12Mh which puts them squarely in RX 550 ballpark.

Looking forward to posts/pics/videos of teardowns from owners.

For anyone interested in how Bitmain achieved this here is a look at the specs/hardware.

There are essentially 18 RX 550's crammed into this thing, and they achieved ~102 GB/s bandwidth using DDR3 which is pretty impressive.

Looks like each ASIC is simply a 4 bank 128 bit wide memory controller with a small number of cores to take care of the hash function. Each bank is controlling the 8 16bit memory modules running at 1600 Gb/s = 8*16*1600/8 = 25.6 GB/s per bank, so 4 banks = 102.4 GB/s of total theoretical bandwidth which equals about 12.8 MH/s of theoretical eth hashrate. (note this hardware WILL be obsolete past 4GB DAG size).

Looks like each card is doing ~11 MH/s so they got within 90% of theoretical bandwidth.

This hardware just shows how hard it is to scale ETHASH even with and ASIC. Unless they beat the memory manufactures with some crazy new variant of memory chips, they will still be close to GPU speeds.

Now the interesting part gets when you evaluate this architecture with them mostly likely running these currently with GDDR5 modules. Power will remain the same or close to it, but now you have a crazy 1,024 bit wide bus running faster GDDR5 which is around 28 GB/s for EACH module, so you'd have ~900 GB/S of memory bandwidth...using the same 90% efficiency wed have about 100MH/S per ASIC...

Pretty sure they are already running this unit in their farms, probably looking at 1.8 GH/s ~ 1000 watts.

Of course the huge difference will be in price...they went with DDR3 to build the lowest cost/bandwith possible...each module of DDR3 probably cost them ~1-2 dollars per IC. Which makes sense. Each Batch 1 unit costs 800, and has about 800 dollars worth of DDR3....so they probably dumped all the units they were secretly mining for a year or two at cost, and are now building new units with a 1k profit margin.

Now GDDR5 is a bit different since the smallest module size I could find is 2Gb (but I'm sure with their volume they could contract hynix/micron to make cheap 1Gb modules for them). Either way they would probably go for 2Gb module on  a new machine to have 8 GB of RAM per ASIC and future proof it. An 8Gb module goes for about ~8 dollars, so we can assume this would cost them at LEAST $2 per module. So were looking at ~$1200 in GDDR5 cost per unit, and maybe a total of 1500 build cost for Bitmain.

If they are running these which they most likely are, they are recouping the cost within 1 month, and could probably easily sell these for 5k+ if they wanted.

That wont do anything, they are running at 1.6 GHZ stock so they have hardwired clocks inside the miner. Looks like they learned from Zcash miner and are now locking down all their miners.

Either way based on the memory specs these wouldn't go much higher anyway.

If you create a backup of the config you can open the bnminer conf file and potentially edit these:

"bitmain-freq" : "350",
"bitmain-voltage" : "0706",

Seal it up and upload it back to the unit. Now, I have no idea what the appropriate values are So do that at your own risk.

Received mine right now!

My one unit (batch1, bought at 800 USD per piece) is shipped, it will be interesting to have a look and test this miner.

I have a 9 card RX550 4GB rig that does 128MH/s at 410 watts. Extrapolating that to 200 MH/s that would be 640 watts.

My 12*1050ti rig gives 191h/s at less than 700W.

I've tried but its very very difficult or you need some extra high ASIC quality GPU to get it to consume only 110W from the wall, even with a Gold PSU.

You might be able to get like 120-125W per GPU but it won't be hashing at 29H/s more like 27/28MH/s or so.

If you set the voltages that low you will keep getting random freezing that will cause you to lose even more profit.

I don't see an option to change clock speed or mem settings in E3.
I was unable to setup using antpool. I added new worker, add the same worker in E3, waited for :15min. nothing got updated in Dashboard except one E3 worker is connected with 0 h/s. Hardware as also showing 0h/s.
I am using eth address and atleast it is showing around 190h/s. Anyone knows whats the payment threshold when using eth address as worker.

7 x RX570/RX580 at 29 H/s = 203 and power consumption is 110-115w x 7 + 35w on CPU = 805w-840w from wall.

Probably not. That's efficiency level could difficult to beat. Even if lets say some we have an rx 580 (which seems to be extremely efficient at mining ETH) doing 31 MH at only 110 watts (very low voltage), you would get 186 MH/s for 810w (660w+150w because you add the power consumption of mobo, cpu, other components).

Like many have mentioned before, the E3 is still more efficient than GPUs and would have been a solid buy at $800 (first batch price).

some quick maths, feel free to correct.

spec sheet seems to indicate that each module is 8M x 16bit x 8 banks

(8x 16bit)/8 = 16 bytes
8million x 16bytes = 128MB per chip
32 chips per package = 4GB per package
6 packages per board = 24GB
3 boards per E3 = 72GB DDR3 total.

if i recall correctly that's exactly what one of the early rumors said.

but it looks like since its made up of 18 smaller units, it might only last until the dag exceeds 4GB, but i'm not sure if they are pairing 2 boards together or not and sharing the memory resources, so it might act as 9 different 8GB units, the screenshots of the miner page seems to show 9 units with 2 chips each.

760w at 200-205mhs on youtube. Can any rigs get that or better?

found this video on youtube (its not mine) : https://www.youtube.com/watch?v=ew6mL5BjpdI

it is using ESMT M15T1G1664A DDR3 memory modules.

guess the rumors about DDR3 were correct. and its using a Bitmain BM1790 chip.
