Hey guys,

I have just set up my miner for ethereum on windows 7.

I use catalyst 14.4 and qtminer.

qtminer started and successfully created the DAG files - now it seems like it is mining - but GPU-Z shows me 0 % GPU load for every card.
And the miningpool also shows no shares.

What's going wrong here?

What is your hardware ?

I already solved the problem.

When I started it it told me that it can't find a gpu with enough memory.
I deleted the -G argument... that's why it used my CPU and not the GPU's.

Usually it should work... I don't know what's the problem anymore.

I use 2 HD 6970 and 2 HD 6990.

And I set max alloc to 100% ... and still can't create the DAG..

I use
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1

but  u can try also
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

Do you use QtMiner or Ethminer?

I inserted all the arguments that you mentioned and still get " No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument"

Ethminer

Maybe I'll try Ethminer. But I don't know how to start it. What do I need?
The ethminer.exe and do I need a proxy or something?

If it doesn't help
As I see first u have to create dag file ?
Next step u have to check other drivers for example
http://www.guru3d.com/files-details/amd-catalyst-14-7-rc3-%2814-200-1004-august-11%29-download.html (http://www.guru3d.com/files-details/amd-catalyst-14-7-rc3-%2814-200-1004-august-11%29-download.html)

proxy depend on pool you are mining now id doesn't matter

Several people told me 14.4 is the only driver that works for my cards.

I have the ethminer.exe now. But how to start it? with a Batch or with commandline?
I mine on http://ethpool.org/ which requires a proxy - but I don't know how to set it up.

U can try http://nanopool.org/help

"To start mining with stratum, you must download, configure and run eth-proxy."

I don't use proxy  ;D
Just run  
ethminer
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
ethminer.exe -F http://us-east1.nanopool.org:8888/0x72_YOUR ADDRESS -G -t 4


or
setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
ethminer.exe -F http://us-east1.nanopool.org:8888/0x72_YOUR ADDRESS -G -t 4

Json RPC error. Couldn't connect....

It could take up to 1-2 minutes to establish connection between the pool and the miner (DDOS-protection).

During this period you can get JSON-RPC problem messages in the console. It`s OK.

or try EU pool

ethminer.exe -F http://eu1.nanopool.org:8888/0x72_YOUR ADDRESS -G -t 4

Same problem here - and even after more than 2 minutes nothing chages.

Not sure where you get ethminer from
I have from here
https://build.ethdev.com/builds/Windows%20C%2B%2B%20develop%20branch/Ethereum-win64-latest.exe (https://build.ethdev.com/builds/Windows%20C%2B%2B%20develop%20branch/Ethereum-win64-latest.exe)
Just install in some folder on deskop
Inside u will find ethminer

edit
When u start install just mark "Add Ethereum to the system PATH for all users"

I installed everything... But I can't see anything.. nothing was created.

C'mon just use search option in windows
Offcourse u are on 64bit
edit
I told you "Just install in some folder on deskop"
if not check C:\Program Files\Ethereum 0.9.41

I installed the official ethminer now and started it with your data - but it can't connect to the server.. don't ask me why. I tried both. The us and the eu one.

ethminer
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_HEAP_SIZE 100
ethminer.exe -F http://eu1.nanopool.org:8888/0x72_0xD5B1C0b4a418F512D37645F57c0Cba6D44bAdaA0 -G -t 4

0x72_0xD5B1C0b4a418F512D37645F57c0Cba6D44bAdaA0 isn't your adress, it's 0xD5B1C0b4a418F512D37645F57c0Cba6D44bAdaA0. So just remove the red part and it should be working...

try dwarf as a pool, for the dag try to delete the old dag and restart the system, and see if the cpu usage is at 100%

I paste  ithat example maybe to fast  ;D

lol :)
He should have seen it... :)

Wouldn't be the first time people just copy&paste without looking at what they are copying ;)

why u dont try the claymore miner?

https://bitcointalk.org/index.php?topic=1433925.0

ethminer doesn't run even if I delete the adresspart. It can't connect. json rpc error.

The claymore miner reqires 7XXX or 2XX or 3XX cards. And catalyst 15.12.

I tried claymore now (ETH only) - it got very good speed of over 50 MH/s ... but not long..

Hey guys,

here is a step-by-step tutorial for solo-mining with ethminer: http://etherbasics.com/tutorials/ethereum-mining-solo-tutorial.html (http://etherbasics.com/tutorials/ethereum-mining-solo-tutorial.html)

and a step-by-step tutorial for pool-mining with stratum proxy: http://etherbasics.com/tutorials/ethereum-mining-pool-tutorial.html (http://etherbasics.com/tutorials/ethereum-mining-pool-tutorial.html)
 

I used this - but it still doesn't work.

I get the exact same error as I get all the time.

Not long because some cards don't work and therefore watchdog stops the miner. Add "-wd 0" to your command line to ignore failed cards as I told you already:
https://bitcointalk.org/index.php?topic=1433925.msg14837013#msg14837013 (https://bitcointalk.org/index.php?topic=1433925.msg14837013#msg14837013)
Then when you confirm that it works, use "-di" option to select working cards and you can use non-working cards to mine something else if you cannot make all cards work.
Have you tried it? It seems no, instead you created several threads to discuss your problem.

I love you :D

Sorry for not following your instructions earlier.

It seems like it is working like that with -wd 0.

As far as I can see GPU #2 does not work.

Do I need to do anything else or can I just run it like this?

EDIT:

GPU #2 just started to mine.
So all 6 GPU's running like that :)
