1st Try at GPU mining ETH, I think I owe !

[HashZilla]

Hello;

I wonder if someone could help understand my results.

Background( Windows 7, Sapphire Nitro RX 470 8GB, OpenCL installed, eth installed.)

My first attempt at mining does not look successful, as eth doesn't seem to recognize the GPU. 


I used the following command....

c:\Program Files\cpp-ethereum>eth -v 1 -a (my address) --client-name HashZilla -x 50 -m on -G


I got the following result....

cpp-ethereum, a C++ Ethereum client
No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G argument


So I set the OpenCL parameters and tried again....

c:\Program Files\cpp-ethereum>setx GPU_FORCE_64BIT_PTR 0

SUCCESS: Specified value was saved.

c:\Program Files\cpp-ethereum>setx GPU_MAX_HEAP_SIZE 100

SUCCESS: Specified value was saved.

c:\Program Files\cpp-ethereum>setx GPU_USE_SYNC_OBJECTS 1

SUCCESS: Specified value was saved.


c:\Program Files\cpp-ethereum>eth -v 1 -a 0x7643715CF78eB75ee857f7203B3365741205
6655 --client-name HashZilla -x 50 -m on -G

No GPU device with sufficient memory was found. Can't GPU mine. Remove the -G ar
gument


I checked the device list....

c:\Program Files\cpp-ethereum>ethminer --list-devices

Listing OpenCL devices.
FORMAT: [deviceID] deviceName
 

•   Ellesmere

        CL_DEVICE_TYPE: GPU
        CL_DEVICE_GLOBAL_MEM_SIZE: 8589934592
        CL_DEVICE_MAX_MEM_ALLOC_SIZE: 4244635648
        CL_DEVICE_MAX_WORK_GROUP_SIZE: 256



I also specified the GPU device with the following command....

c:\Program Files\cpp-ethereum>eth -v 1 -a 0x7643715CF78eB75ee857f7203B3365741205
6655 --client-name HashZilla -x 50 -m on -G --opencl-device 0

Is this the correct device information for the RX 470 ?


Thanks

Use claymore dual miner.

Load Amd 16.9.1 drivers

[HashZilla]

I loaded the 16.9.1 hotfix which provides identical results with the eth package.

Are you suggesting my efforts should have worked, and probably would with Claymore?

thanks

[HashZilla]

16.9.1 + Claymore works!

thanks
