DOK. my cards don't work well with the drivers 18.5.x and 18.6.1 (even in stock frequencies), stable work only with 18.3.4. with i 54, w 8, f 1, t 2.
rig 9xSapphire 580/8 special edition, HYNIX H5GQ8H24MJR
999000000000000022339D00CEDD6B4470551414B80D960B0040C400750314204A8900A00200000 018123745B92B3A16. (this timing is the best and stable for me) 1230-1250/2100-2150 (880mv) - 1135-1165h/s on the haven algo.
If i>54 and f>1 + 2 threads = crash cards. in 1 thread i can start miner with i=100 f<=16, but hashrate is low and only 8 cards and 1 card (random)need low settings (i 54, w 8, f 1, t 2) 9 cards = crash. any ideas?
