You are kidding right?

No, not at all. I have been working in Semiconductor fabs for 20 years. But it depends on how they designed the chips. If you shrink the geometries inside a chip, you do save on power consumption and gain speed. This means you can also fit more transistors inside the same size packaged chip. So the question left is if Ebang/Samsung used the same amount of transistors to shrink the package size of the chips, or did they increase the amount of transistors inside each chip? It is also possible that they increased the clock speed (frequency) of the chips as well. Where smaller geometries produce less heat, you could increase the clock speed to obtain higher hash processing speeds. Either way, putting more chips on the board will require more wattage and so will increasing the clock speed.

Haha, that makes sense. If you read your previous msg you can see how it can be misinterpreted Smiley

I was there at the e10 presentation in HangZhou, China.

The chip was produced by Samsung, the design of it and the PCB by Ebang.

There were 4 teams of non Chinese people at the event, 3 from Russia and 1 from Serbia. Every team was a large account to Ebang.

When they announced pricing, everyone was kind of a stunt. Everyone came optimistic to buy a whole lot, like 1000 machines. On that day they offered e10 for $5500, and no one bought anything. Smiley

Next day they lowered the price to $4900, and I still think that no one bought anything.

First batch delivery is set to 20.1.2018

Machine is real, I have seen it working, but just a bit expensive.



Did you think it was weird that they and Canaan did their events at the same time?  That obviously wasn't an accident, but I can't figure out which one was trying to steal the thunder. My guess is it was ebang messing with Canaan. They just seem way more.... Chinese.

Yes this was disappointing. At $4400 each it would take an $88,000 investment to get them. Unless your BTC rich. It’s not gonna happen. I’d like to try one. At 18Th/s you could still roi in 90 days. I’d take that over an S9 at the prices they sell for.

It sucks because I am setup for 20 miners at my house. That’s  all I have power and plugs for. It sucks thinking about them roi in 90 days and the kind of monthly income that would come after that. I would have to borrow the 88k to buy them and then they would all have to work. Too risky. No can do, but dam I dream.

Do you have a normal power source? How can your network support 20 miners at same time?

most newer single family homes in the US over 1200sqft are going to have 200amp service which is 48,000 watts, if your running 1600w miners that's about 30 miners, run 20 and you have plenty of power left over for your actual home. 200 amp service entrance is quite common.
YOu can request up to 400amp residential service with no special requirements needed on the homeowners part except of course a 400 amp service entrance. Also, you can have as many meters as you want (pending local codes, some urban municipalities ban this), lots of people have a separate service entrance for their house and say a barn/outbuilding, so you can have 400amps on your house and another 400amp service on your barn, no problem.

Yes 200 amp service at my house. 20 miners at 1600w is maxed out for me. All my appliances run on gas so all I need electricity for is lights and my fridge and freezer.

Let me back up a little here. I have the ability to run 20 miners but I dont have 20 miners. I add one or two here and there. As things like noise and heat become an issue. They will be addressed. I have a room in my basement for them. It stays cooler down there all year long and the heat can be evacuated through the window. This is all temporary since I have a 3600Sq/f building being built on the other side of my property. It has its own 200 amp service and 16 foot ceilings to get heat up and out. I just dont want to wait for it to be done to start mining. That's why I threw that sub panel in the basement. I may never have 20 miners down there but it will be easy for me to unscrew it from the wall and move it all out to the building once its done.

Is there any real user's feedback ?    Ebang’s Ebit miners are mostly popular in Asian countries, though they are trying to get to a wider market and their latest announcement of a 10 nm ASIC miner – the E10 made some waves.  It is however an expensive device and still hard to get with a minimum purchase quantity of 20 units and all batches already sold through the end of March.

I've seen absolutely no news about the E10 yet, but from what I can tell from their website the first few E10s will come out at the end of this month.

Miner reliability and customer support is something else you missed with the cons of the Ebit miners. This post and the quote within it should be enough to keep you well away from Ebang as a whole. Pricing on these things is a joke, and you're much better off even just getting an S9.

That's right. Ebang's customer service suck so hard, I can retire my vacuum cleaner.

Wouldn't buy anything from EBang in my life again.

As far as I know, Ebang has already started shipping the March batch of E10. Probably not all the miners are shipped (yet), but I already see offers from Chinese resellers to ship E10 within 1-3 business days. I didn't see any end-user feedback yet, though.

what do you need to hear guys as feedback?
about e10.1
1. the software is as crappy as previous e9+. still no root from manufacturer (but it can be hacked)
2. hashrate is as described, power cunsumption is like 2.2-2.4kWt
3. psu is integrated, it works
4. main board is connected directly in the blades - so no more wires except fan wires

but overall - it works

upd - didn't measure power using some special stuff. please check msg below with more info

say thanks:

Wow, so the power consumption is much more than was originally advertised.

I guess we know now why Ebang doesn't want to show the power consumption number at the website anymore.  Grin

So they lied about the power specs?? Are they refunding for the difference vs what was promised?? What makes these worth $5500 for 18th/s vs antminer s9 that is 14th/s at $1400 (less with coupons)?? Idk how they managed to make a 10nm miner (i think thats what i read if not sorry) but uses A LOT more power than a miner that is over a year old and counting. Not only that they set the price super high for some odd reason...seems like they got too greedy.

I heard they were selling them in Feb almost twice cheaper than $5800. May be now they can sell it for 15 hundreds lol

Regarding consumption - I'm sorry, let me be more specific
I didn't have opportunity to measure it using some special equipment, but I had power strip designed for max load 2kWt - it was good with 1.8kWt and 1.6kWt loads previously, and it didn't withstand this unit (powered off after ~30min)
So I concluded it's a little bit more that 2kWt (but definitely more than 1.8kWt)


update: 680pll, 19Th, consumption between 2.1 and 2.15kW

Hi All,

Today I experimented with different PLL settings on E10, measuring power consumption along the way. My power meter isn't fancy - just a cheap device bought on Ebay. Though, based on my experience in the past, I find it to be quite precise for my use.

So, the device is Ebit E10:
Systems software version: v8.0.0.38
Hardware version: EBAZ5506-02-QB_v1.0
FPGA software version: Fpga v1.0.2

The E10 is set up to work on Kano Pool. The only thing I changed is the PLL. I waited for at least 20 minutes after each PLL change, so that the miner would speed up and reach the expected performance.

The results are:


Notes:
I was unable to set PLL = 700. The value returned back to 680 after a reboot. I didn't try any values above that.
I didn't try any PLL values below 450 (is there a point to check these?!).
PLL = 601 is how it was reported in the Miner UI when I set it to 600. Looks like a rounding issue somewhere in the software.
PLL 500 seems to be LESS efficient than PLL 550 and 600. This is not a measurement error - I rechecked that several times, and always got about the same result.

Hope this helps...

P.S. I also tried the "Systems software version v8.0.0.58", but it doesn't let me set PLL to 680 (looks like 660 is its maximum). Therefore, I made all the tests with v8.0.0.38 and that's the version I'm running on my production machines.

Yesterday Ebit published an upgrade for E10 containing BOOT5506_0B.bin and top_ctrl16_0B.bit files.

Quote
This firmware is for hardware upgrade and reinforcement, which can optimize the hash rate and make the machine stable.

The upgrade procedure involves Ebit's MinerMini utility to upload the new firmware. It also insists to have SW v8.0.0.45 installed prior to the upgrade (included in the package).

I successfully did the upgrade, but didn't notice any significant changes. The only visual change is the hardware version field changed from EBAZ5506-02-QB_v1.0 to EBAZ5506-0b-QB_v1.0

I stayed with the SW v8.0.0.45 after the upgrade. This version allows PLL to be set up to 680 (inclusive), and seem to work fine so far.
