Topic: Ebit e9 miner with 6.8Th/s from Ebang company a new rival for existing producers - page 27. (Read 80702 times)

Was gonna say wth myself but resisted. So much for that idea...

Ya. 'Switch-mode' refers to how the power is controlled. It is chopped on-off very fast and the average on-time determines power out. Very efficient. Often used for DC regulators but also applies to AC systems eg a dimmer switch.

The other way to to it is using Linear control. Very clean output but bulky and not efficient as the voltage difference between the DC feed supply and output is directly impressed across power transistors and dissipated as heat.

You're terminology is incorrect, what you're asking about is Voltage auto sensing, not switchmode.

Are they swtichmode powersupplies? As in do they provide 240V and 110V or just 110V?

My order experience from start to finish:

Paid $1334 via PayPal for 2x Ebit 6.3Th miners on 4/16/17 around 9:30pm CST.  After payment I forwarded the paypal confirmation to [email protected] (per their instructions).  I had not received a response after 24 hours so I sent another email on 4/17/17 asking if I needed to initiate a chargeback through paypal and I got a response back from Lynn Xie on 4/18/17 asking for more information for shipping.  I provided that and then I was asked for my fedex shipping account info because the $1334 did not include shipping.  I told them I wanted to know the shipping cost because if it was too much I would just cancel.  She replied back with a quote of $100.  I then added her on my Skype (username was in her email from her email) and used that as my mode of communication from then on.  I replied back saying send me a paypal invoice and I'll send payment right away.  Since it was the weekend for them (april 22 and 23) I got an invoice late on the Sunday 4/23 evening (Mon 4/24 for them) which I paid promptly.  I emailed the paypal confirmation per her request and provided her with more shipping verification (address, company name, etc).  on Mon 4/24 I received a skype message asking if I could pay $50 more for shipping, to which I replied I pay less than $100 for 2x Antminers from Bitmain and receive them within 3 days of shipping.  She checked the shipping price again and then notified me they had shipped (received that notice around 3am CST Tues 4/26).  I was provided with a tracking number and they were shipped international economy, which apparently takes 4-5 business days to get to Louisiana.

The miners look to be made well and the current one I have is hashing at almost 6.5Th.  The fact that these can be used on 110v power since they only use 900 watts or so is a bonus.  power requirements are 6x 6-pin PCIe power connectors (3 for each board) and my killawatt shows around 1000 watts, but you cant use my numbers as they only way I could power this with 110v (in order to use my killawatt) was to use 2 power supplies (1 for each hashing board).  So true power usage with 1 power supply should be closer to the 900 watts.

Overall not a bad experience with a company that I had never ordered from, allowed payment using paypal, different language, and a 13 hr time difference.  While the price per terrahash and the power efficiency is not as good as an Antminer S9 or T9, the fact that you can use 110v and get a 6.3Th miner for $717 seems to be a good deal ($717 cause that's half of $1434 total cost).

I received 1 of my 2 Ebang e9 miners today (along with 2x Antminer T9's).  This was not Ebang's fault, it was FedEx fault.  Still waiting to receive the other one, but this one is working great.  I plugged it up, it received an IP address from my router, I browsed to it through a web browser and logged in with the default login (admin/admin).  I was expecting a Chinese interface but to my surprise it was english based.  So right off the bat I was getting more than I expected.  I easily browsed to the cgminer configuration page and entered my 3x pool info (miner address, worker, password) and saved it and it rebooted.  A minute or 2 later it was mining on my primary pool and has been running great ever since.  I will post pictures and my order experience from start to finish very soon.  I have to get some other work done today as well!

Waiting news from you, in the mean time how much did you pay including shipping ?

according to the fedex tracking I should get my 2 units by Monday 5/1/17.

It's different companies. And different equipment. A4 is for LTC by Innosilicon.
As for the Ebit or Avalon so far we hear positive reviews although the Ebit sample is small.

I saw them.  I wanted to see if the different batches were consistent.  With the A4's the first batch was perfect, and the second batch didn't run right.

received my tracking number, and fedex tracking shows it did ship on 4/25/17 and is currently in transit.

The first page of this thread has the pictures I took including one showing how they hash.

They average about 6.4th/s when working. I have a number of machines that have broken 30 days uptime already. As long as they work out of the box they require very little maintenance so far.

will do.  received and paid an invoice for the $100 shipping yesterday and have received communication from them.  I'll post here when I receive shipping info

If you wouldn't mind, when the units arrive would you take photos and let us know how they hash?  Thanks.

wow havent posted in a while.  ignore my previous signature!

I live in Louisiana, USA and have placed an order for 2 of these units from their website.  was able to order using paypal so I figured worst case I would just reverse the charge on my CC.  I received and email after placing my order that shipping price was not included and is an extra $100 for the 2 units.  I will be paying an additional $100 paypal invoice that they will send to me Monday (monday in china so Sunday in USA).  I will let everyone know how quickly I receive these units.

Here is a nice tutorial someone wrote up to navigate the chinese firmware

i want to buy some..
any way to get interface Language in english???
i will try to find customer support on skype to ask better...
but until now, i get no info..

I have 5 of these. They seem to hash about as advertised on average. 6.4 th/s @ 882W. Not quite as efficient as the S9. As for noise, they are about the same. They don't use cgminer. If you are using remote monitoring software like awesome miner, they aren't supported as yet. The interface is kinda interesting. You can change the frequency from 400M-715M, and fan speed - Low, Medium, High. But since it's all in Chinese, it's way more cumbersome to work with.

is it better to buy than than the S9 or T9?

Already have a few 741's. if the E9 is for real, it's a bit better on power and cost so wanted to try one but looking for some trusted reviews first.
