Alright actual question here. Might be worth another thread.
I restarted my rig. 4/6 Vega 64's are hashing at 1900+ still. 2 are not. No matter what I do with the HBCC slider for those cards, enable, disable, I cannot get the hash rate back. The card is otherwise clocked correctly, I get the same ETH hash rate as I would expect.
Any tips? Full clean re-install of AMD drivers? What I wouldn't do for some non-flashy software that would let you control these settings.
I confirm this problem. No matter what you do HBCC will enable only 4 first cards.
I think it drivers problem that does not support > 4 VGA yet
Well ... I have strange idea but I think it worth to try.
You know that running 8 gpu nvidia rigs with ccminer can be not very good as you will see ~50% cpu usage with weak cpus like celeron g3900.
And now we have problems with 6 Vega rigs.
So I think it is good to mix 4 nvidia (gtx1080 for example that are best in performance/hashrate ratio on zec and other non-memory algos) and 4 Vega cards in one intel based 8 gpu rig (or even 9 gpu rig (5+4) or more if you have such mb)
