Edit: AMD 14.6beta is behaving strangely with me after I tested for hours, it is the issue:
Whatever I tried to change the GPU/Memory frequencies, it is still the default (factory) values, whether I tried it via MSI after burner or via the miner's conf. file, though GPU-Z shows that the frequencies had been modified, but in fact the REAL ACTIVE values are the factory's one, and the hashrate had not been changed what so ever.
I dont' know is it me or is it the driver.
I downloaded AMD14.4 driver, tested it. I confirm it is working perfectly, the performance is the same of 14.6beta PLUS you can play with the frequencies.
This issue lies with MSI afterburner...
(actually I had that problem since some time and it isn't limited at all to 14.6 and was stuck for some time at 1080 which isn't my factory clock).
No get past that, you need to kill msi ab and restart it (or restart the computer before)
Considering the speed increase, you lose it if you don't use 14.6 (although, there were some report it was possible to use bin file generated in 14.6 in older version of the driver.
Thank a lot djm34, I will give it a try too.
It was weird for me cause this is the first time ever facing such thing.
btw, as long as you are the creator of this new miner, would you like me to lock the thread and divert the readers to your topic now as long as this thread's reason (alerting as many users as possible about the the miner had been fixed) had been fulfilled?
