Hi , i have a problem with new one Vega 64 rig ( 6 x Vega 64 ) , when using official AMD driver 17.9.1 there are no problems , everything is working as is should , i can get 38mhs eth stable and 44 exp stable with core 900 / 1100 memory on 875mv both using OverdriveNTool . Try to test xmr with this setup and geting about 650 per card , which is expectable , try to set on HBCC on every card , but cannot success , I can enable it only on 4 of 6 cards , other 2 set it on , apply , drivers resets itself and stay off , tryed anything and on card 2 and 3 cannot enable it ? Any ideas ?
And another question I try 23 Aug Blockchain driver , clean install , ddu , driver installs OK , but machine stuck with artefacats/grey lines/ grey screen seconds after start miner no matter eth or xmr , stuck on default settings , stuck on downclock/downvolt settings too, so I returned to 17.9.1 , any ideas what can I do/try to make blockchain driver to work ?

edit: Rig is with 8 gigs of ram, intel celeron 1151, 6x vega 64 , I have HBCC slider on all 6 cards , but only on 4 I can enable it and move the slider , virtual memory is set to 32gb ?  Maybe this is the problem 4 x 8gb = 32 , will try with 64gb virtual memory whats gonna happen ?
