I had similar problems.
And I had a problem with C ++ There must be both x64 and x86 versions. Otherwise it falls

!!! Visual C++ Redistributable for Visual Studio 2012  !!!


Reinstall, but need to have x86 !

While it's x64 system

You have in the system one GPU ?
Other gpu for example, the motherboard or CPU

 

ethminer --list-devices

Send screen :

ethminer -M -G

Sorry previous them for AMD


This is ok for NVidia >

@echo off
setx GPU_MAX_ALLOC_PERCENT 95
setx GPU_USE_SYNC_OBJECTS 1
ethminer -F http://80-eth.suprnova.cc:80/username/password -G --cuda-grid-size 8192 --cuda-block-size 128 --cuda-schedule auto


 --- Ethminer 0.9.41 ---

And how much system RAM MEMORY ?

Try this ...

@echo off
setx GPU_MAX_ALLOC_PERCENT 95
setx GPU_USE_SYNC_OBJECTS 1
ethminer -F http://80-eth.suprnova.cc:80/username/password-G --opencl-platform 0 --no-precompute --cl-global-work 16384

What is your GPU - more precise parameters How old are you + system memory

My goodness what it is big and what it has weight.
When installing the crane will be needed.

But otherwise Spondoolies nicely surprised.
Please Take home something for mining as SP40.
 

Please create a new topic for companies that no one heard, and no real sale. Just waiting for the people to pay them ahead for a product that does not yet exist.


This is a forum where the most people intelligently

Or am I wrong .....

Topic of existing hardware instead of mythical devices for the dumb

Yes -t X
X: number of GPU used for mining

Unless graphic card is at least 2 gigabytes , is do not start.
Ram GPU  is used least 1,090 megabytes
And also need to be 64bit operating with at least 4GB of RAM.

ethminer -G -t 7 

And each graphic must have the output DVI adapter Dummy.
Without it remains off

How does it look from any other events that supplies hardware SP20?
They still produce or plan new hardware ...
Maybe there's someone asked, but I found the answer ...

Sendig from ?

look out for products Spondoolies-Tech and Bitmaintech ...

I know you do not sell any new minery

Could you advise seller Bitcoin Hardware in EU ...
only verified

I know that there is a section selling hardware but almost everything is outside the EU.

Thank you for the tips


 

Right move people need to know all of this information 

So today I got a replacement for my defective miner.
And I can confirm that I have received operational.

But one big minus. Write to websites that sell used stuff !!!
This mineral should have been driven for at least 1/2 of the year. So it is not a new device ....

But the conclusions for the money I got what I asked for
