I recently put a machine on ETC and updated the drivers to the blockchain drivers, so the machine mines faster now, but is more unstable, even when I shut off dual mining. Can anyone share with me their run parameters for a Sapphire rx nitro (non-plus) 480 8g card? I am running windows 10 with v 10.2 with the August 23rd blockchain drivers. Would love a suggestion on how to get this to run stable and not have cards tripping out. I have tried raising and lowering voltages, lowering ethi to 1, and turning off dual mode, but not really found a stable set up. Appreciate any thoughts.
Thanks
I'm using this config.
-epool eu1.ethermine.org:4444
-ewal xxxxx
#-eworker
-epsw x
-esm 0
-allpools 1
-mode 1
-estale 1
-ethi 16
-gser 2
-wd 1
-r 0
-dbg -1
-tt 75
-ttdcr 80
-ttli 85
-tstop 90
-cclock 900
-cvddc 800
-mclock 1750
-mvddc 800
-powlim -10
Works like a charm on my 6x480 rig

If you are on Linux OS, may I suggest you do a simple test: stop miner, edit config.txt by adding comment (add #) on those 2 lines (# -cclock 900 and # -mclock 1750). Then restart the miner. Did you see any difference in the GPU´s hashrate?
