ethminer.exe --farm-recheck 3000 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22  --cuda-devices 0 1

Wait for the dag file to be created.

So it's              --cuda-devices 0 1

Yes.........    thank you sp
A working bat file for windows 8.1 with 2 cards.

ethminer.exe --farm-recheck 3000 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22  --cuda-devices 0 1

--cuda-devices 0 1

or

--cuda-device 0 1

I don't remember the exact syntax.

how to mine with two card on ethereum? -d 0 1 not working, -t not working either

Open it in the command line window. What is the error message?

You can try:

ethminer.exe --farm-recheck 3000 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22  --cuda-devices 0 1

the batfile must be in the same folder as the ethminer.exe file.

Giving it a try  thank you sp

EDIT: doesn't work opens then closes instantly.
This works for one card....... but adding --opencl-device 1 to that won't work either.
ethminer.exe --farm-recheck 3000 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22   --opencl-device 0

ethminer.exe --farm-recheck 3000 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22  --cuda-device 0 1

or --cuda-devices don't remember the exact syntax, but you need to seperate the devices with a blank and not a comma.

Thank you
That didn't work either.

Could someone please show me their bat file for 2 cards on one rig with windows 8.1 please.

Thx

Do you mean  -d 0,1 is wrong? ...... so should be  -d 0 -d 1      ?

This doesn't work either     --opencl-device 0  --opencl-device 1 doesn't work either.

Could you please show me you bat file for 2 cards on one rig with windows 8.1 please.

you need to remove the "," to make this work, apparently it was removed in the last version?

For reference, by 390X ($369 at my local retailer) is doing a average of 34MH.
The only changes in my run line are -
--cl-local-work 256 --farm-recheck 200

How do I get ethereum miner to recognize 2 cards on the same computer ?... it only mines one of 2 cards .nvidia 980ti at 22 mh/s.
It should have  -d 0,1 but doesn't work..like cuda should.
Thx

EDIT: This my bat file that doesn't work      

ethminer.exe  --farm-recheck 3000  -o http://eth-us.suprnova.cc:3001/razorsedge.eth1/22

On the donation bat file I get 1 card 980ti that gives 22 mh/s...but this bat file above doesn't work.
Please help.
thx

EDIT: I have
ethminer.exe --farm-recheck 3000 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22  --opencl-platform 1
Working with one card.
I have 2 750ti too on the rig.

Still won't mine with the other 980ti card......

EDIT: I got it
On cuda devices are called out with the -d argument ...but he changed that.
So ethminer -G --opencl-device 0     ethminer -G --opencl-device 2       =    -d 0,2    ect.

A working bat file for windows 8.1 with 2 cards.

ethminer.exe --farm-recheck 300 -U -F http://eth-us.suprnova.cc:3001/razorsedge.eth1/22  --cuda-devices 0 1

Or in my case  --cuda-devices 0 2  because  device 1 is a 750ti not a 980ti.
The 750ti is useless on this algo.
EDIT: change --farm-recheck 3000 to 300.

But for now it should be working?
After driver crashes I get this error:
`CUDA error in func 'ethash_cuda_miner::search' at line 288 : unknown error.`

as per i know 2gb card will not work in future. mining performance will reduce with increasing dag size and difficulties for all cards.

Any idea why 750ti is not working with latest 1.0.4b3 on windows 7? (Tried 1.0.3 and some ethminer from suprnova pool as well)
Getting 0kh for few seconds and then driver crashes.

Using 361.75.
Am I missing some requirement?

isn't 970 better cheaper and the ratio is the same or in favor of a 970, maybe you are referring to the density per rig?

I think I compiled it correctly. Any way to see if I am using the new Ethminer versus the old one? Anyway to see the version? like Ethminer --version ?

EDIT, it says

ethminer version 1.2.0



And I used git clone https://github.com/Genoil/cpp-ethereum/

Thanks Red

Stop using 750ti for etherium, it is useless. Better mine decret or neocrypt with it.
Second, consider moving to win7 with 980 mining eth...
Third, use mining options recomended by Genoil

I am mining etherium with a gtx980 and a 750ti on windows 10 i cant seem to get the speed i should be getting, any help would be appreciated
my rates look like this.
