Hi, unfortunately this is known issue for Vega gpu's(something to do with broken OpenCL compiler in drivers, and this need some tricks in code to make drivers provide correct binary). So far only kernel 1 works fine, but with lower hashrate. And this issue in my TODO list.
Thanks for the information.
This bug, known behaviour makes you not want to use the particular algorithm on this GPU. [RX VEGA 64]
To large a loss of hashrate.
_____________________________
I've noted another oddity when exiting and running WildRig application, the hashrate decreases if you exit WildRig and run another application.
You need a system reboot to restore performance after having had WildRig running.
Seems to lower gpu performance if you exit and want to run another application.
Noticed when I ran another mining software when I wasn't getting the usual hashrate and investigated.
If I don't run WildRig performance is normal, but as soon as I've had it run, performance is lowered afterwards. Can't find the cause other than the application doesn't exit/close properly? Keeps hogging system resources?
Known issue?
For example
ethash has a decrease from
43mh/s down to
36mh/s after using WildRig. Doesn't occur if I don't run the application. (system reboot restores performance)
Any suggestions, comments on this behaviour?
WildRig itself also has decreasing performance for each exit/close and new start. But not as noticeable at first, until you only run it once per system start where you get the best performance. If you close the application it's for me recommended to restart the system if I want to run another algorithm, otherwise I can't get the best results from it.
