for those who installed this driver, did you see any movement / decrease from your hashrate?...
Been running this driver for last 4 days. Works like a charm.
1- At time of driver change, had an extra 7% average boost on hashing speed. Didn't have any change in power consumption like some are claiming (tested at the wall).
2- I'm almost entirely working with RX580 and some 570. So I can't claim it works well for the 4xx series.
3- Last DAG epoch did NOT change anything on hashing speed.
Overall I'm really glad this fix has been provided here. 7% gain is huge not to mention it would have been worst on each epoch. Unless a new official AMD driver is released and provide another increase in overall MH, I will probably stay with those for a while.

Tried to to my first rig.. mixed 570 and 580 AMD Cards.. looks like robinhood is correct at this point.. still observing my hashrate & effective rate at ethermine.
