If you demand your refund per their online sales agreement, and they dont refund you within 30 days, simply sue them.

It is a case won almost 100% guaranteed and they will face additional legal costs.

I now have the 1th/s unit running at 1th/s and have been assured, by bitmine, that the HCP Platinum 1000w can produce 1500w of power if needed however i cannot find any documentation from Antec that verifys this. I dont know if turbo mode is useable.

I have the same 1000W Antec PSU delivered yesterday. On full populated CoinDesk I can run only normal mode with it. Turbo light dies after some time (couple of hours), turbo moderate dies after a few seconds.

So that PSU seems do not able to deliver enough power at all.....

Support said that I'm the first one of all customers whose CoinDesk doesn't run with that PSU ;-)

Today I attach a second PSU and try the turbo moderate....that should work hopefully.

I ve called also today and spoke to mr. vogel. after a short wait loop he was able to tell me that i ll recieve the refund till end of this week.
Refund is 6 days overdue. I asked how serious is his statement. He answered: I hope so.

[SwissMiner]

.. and have been assured by bitmine ...

.. of course .. you can trust them .. for sure

anybody who run with the bitmine miner in p2p pool ?

1th/s desk in turbo moderate with 1000w PSU (theirs).

cant get above 1.2 TH/s. this would be ok if my CCP unit wasnt fucked. but $6 per gh/s is excessive now. That was ok in Jan or Feb.

edit: turbo moderate crashes after 20mins and gives HUGE HW errors.

are you running nominal mode? and what does the pool shows for the speed?

Does anyone know if and what is the difference between a green and a red module?
Opening my CoinDesk yesterday I realized that my compensation module has another color. The Hashrate is the same as the other modules.

Put a second PSU (now 2 * 1000W) to my full populated CoinDesk, set turbo to ultra and it hashes stable at 1.2 THs, consuming lots of power (1.5KW), low hardware errors. Everything seems ok so far.

So it is clear, the delivered 1KW PSU will never supply enough power for the turbo mode ultra as bitmine told me.

GREEN = Germany PCB

I think it doens´t necessarily have to do with country of origin.

I own a China A1 unit (under 2,5$/GH) and it has golden / yellow pcbs.

It can be by different assembly houses though.

Also, my China A1 achieves 1W/GH with only 4 modules (8 chips per module) so why doesn´t bitmine have better efficiency with 40 chips total? Does their board design really suck that much?

I saw China units with 0,88W/GH with 5 modules (40 chips) at 1TH. Isn´t that atleast 12% better than what bitmine is getting?

anybody who run with the bitmine miner in p2p pool ?

i have actually on bitnode.io.
what information does you need?

it was running smoothly with my 600GH/s CPP.
Right now there are running 5 TH/s url]nyc.bitnode.io:9332[/url]

Got 3 bitmine 1 TH/s desk units. Cant run one of them in anything other than normal (hw errors >1%). One of them runs in power safe mode cuz it produced too many hardware errors in normal (about 5% or more). I have read the ratio accepted/hw error should be < 1%. Some advice?

my miner don't run good at p2p.... i lose more than 10 - 15 % hasing speed....

Did you update the firmware to latest version? http://bitmine.ch/support/firmware/
That should reduce your errors.

Check your PSU, if its only a 1000W PSU (like me) you will not be able to run any turbo mode stable, that's my experience. Attach a second PSU will hopefully help you running turbo modes stable.

1TH Miner consumes <1000W in nominal mode, turbo ultra consumes 1,5 KW currently.

Check your temperature, it should not be so high, what I have seen, the higher the temperature, the higher the errors.

It seems that Bitmine.ch like to play with the nerves of the customers.
No sign of refund + penalities for my order #3876 from December 4, 2013 , delivery February week 3 batch #2
No sign of delivery of the Coincraft Desk + CPP  ..
Or Bitmine.ch just stole  my money ?
Hei, Bitmine.ch are you in the "silenzio stampa" ?

[GodfatherBond]

Just wanted to say thank you for Bitmine tech support.

I had some problems with Desk started last week, friday got help through skype to analyze and on moday received spare part.
That was fast. Now I only wish to receive missing cpp unit.

and today i got my CCD

I advise everyone to open the case and check all connections before to power on the miner because some can be unpluged .
mine looks like got a hit from fedex guys and one conector from display was broken but was easy to fix and move on.
in turbo mode works till 740-745Gh but i tried only 30 minutes.

where did you look at? poolhashrate or cgminer?

booth...
turbo light -> display -> around 900 GH
