Hey guys,

I just wanted to try out this miner because ethminer and qtminer doesn't work right here...

I have got Windows 7 64 bit.
Catalyst 14.4 (becuase a lot of people told me this is the only driver that would work for ETH with my cards)
2 HD 6970 and 2 HD 6990

I can start the miner and it seems like it could mine (on 5 of the 6 cards) - but not for a long time.

I start it with this commands:

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

EthDcrMiner64.exe -epool eu1.ethpool.org:3333 -ewal 0xD5B1C0b4a418F512D37645F57c0Cba6D44bAdaA0 -epsw x

Could someone please help me?

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

http://www2.pic-upload.de/img/30637114/Unbenannt.png

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.

That's would fit to my problem that it does only show 13 Mh.
I think it does only use one of the 6 cards.
But gpuz shows 100% load for all cards... I have no clue


I just tried the claymore dual miner. It is rocking at an increadable fast speed.
It could create the DAG on only 5 of the 6 cards but still has got over 50 MH/s.

That would mean if I get it running on all cards I get like 60 MH/s - and I haven't really overclocked yet.

This is a special unofficial forked version by Genoil which splits the DAG in several parts.

The start.bat was already provided... I did only change the wallet adress and my pool url. You need to ask Genoil if this is right or why the pool is lited twice.

I don't know why the 6900 series shouldn't work for ETH. They have 2 GB of ram and the DAG is like 1,45 GB...

But yes - in fact it doesn't really work.

It shows some mining but nothing that reaches the pool so far.

But there must be some more problems... I did list devices and got this:




BTW: I deleted the second poolurl and now it works. Thanks to Unacceptable


This is the starting screen of the miner - I don't know how it should look like - but the warnings at the end looking strange..



And if you ask me it's only using one card and not all 6.

 6 cards - right so far... but only 2 are cayman the other 4 should be antilles.

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

It works without the -M 12345. But I still have got 2 questions.

It only shows 12-16 MH for 6 6970 chips... that's like 2,5 MH per card which should be possible to pull 8-10 MH each...

My pool doesn't show any shares... do I need to edit anything else?
ethminer.exe --cl-local-work 128 --cl-global-work 8192 -S eu1.ethpool.org:3333 -FS eu1.ethpool.org:3333 --farm-retries 0 -O 0xD5B1C0b4a418F512D37645F57c0Cba6D44bAdaA0.home -G --opencl-platform 1 -E bench -R C:\Ethereum\DAG --farm-recheck 2000


This is shit.. it's fucking slow and doesn't work right...

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

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

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

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

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.

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?

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"

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..

No it doesn't.
I started qtminer and it told me that it can't find a card with enough memory and closes the miner imediately.

@Genoil your miner doesn't work I think.

I just started it but it doe not start to create the DAG file.

Hey guys, could someone please take a look at my problem here?

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?

I just installed 14.4 and now try qtminer with max alloc 100%.

I will overclock my cards. I think I can get like 9-10 MH. And I have got 6 Chips so 6 x 10. With a bit luck that's 60 MH which isn't that bad I think.
