R9 270 only 3000 nonces/min on windows 10
I am plotting on my old R9 270 GPU. My first 20tb I plottet on windows 7. Using the exact same GPU.
On windows 7 I was able to plot with ~15k nonces/min.
Now I have upgraded to win 10 and my plotting speed is only 3k nonces/min.
My devices config loogs like this: 1 0 1024 128 8192
And this is what list all devices says:
 Intel(R) OpenCL (OpenCL 1.2 )
 Intel(R) HD Graphics 4400 (OpenCL 1.2 )
 Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz (OpenCL 1.2 (Build 10094))
 AMD Accelerated Parallel Processing (OpenCL 2.0 AMD-APP (2348.3))
 Pitcairn (OpenCL 1.2 AMD-APP (2348.3))
 Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz (OpenCL 1.2 AMD-APP (2348.3))
The HDD is a USB 3-0 external with 4tb. Coyping already plottet files to that HDD is running at around 140 MB/s. So connection can not be the bottleneck.
Do you have anny sugestions what might be the problem?
- try insall http://developer.amd.com/tools-and-sdks/opencl-zone/amd-accelerated-parallel-processing-app-sdk/
- try to downgrade your GPU's drivers
any driver recomondations? I dont really know where to find old drivers.
@Maverick1290 i'm used http://support.amd.com/en-us/kb-articles/Pages/AMDCatalyst15-7-1WINReleaseNotes.aspx (sorry, i'm sold my R9 270x 1 year ago)
