I've tried out the new official beta drivers on a small test rig, there was no need to apply the 'atikmdag-patcher' patch.
With 17.7.1 drivers I get 59Mh/s with beta drivers I get 61Mh/s.

What are your cards?

Three cards in this rig RX580 , RX480 and a R9 270x. The RX580 & RX480 have modded BIOS.

Funny thing though, tried the new beta driver in one of my 6 card rigs, a mix of RX480's & RX580's with moded BIOS, after beta driver installation all but one card was seen by Catalyst/Claymore - running the 'atikmdag-patcher' made the 6th card visible, but there was absolutely no change in hashrate ?

Edit: Hashrate before beta drivers installed 156Mh/s, hashrate after beta drivers installed 156Mh/s.
