Hi,

I've an 8 x Rx580 rig. I'm on the lastest drivers (18.3.4 drivers only, no CCC /AMD settings).

On 11.6, I was getting a lot of crashshes, freezes, reboots. Until I've realized that it was because I had -cclock 1150 configured. I've reverted to normal clocks, and reduced them indirectly, through power limit. So this stopped the crashes.
I've also tried OverdriveNTool, seems to behave similarly (unstable miner) if i downclock

On 11.7, I've tried to set the -cclock 1150 again. Now it seems that the miner no longer freezes. But the setting just doesn't work now, clock are easily in 1250 Mhz range.


How are you applying your downlcloaks? I wouldn't like flashing  them in BIOSes, because it's inflexible. Best results were for me achieved with Radeon Settings app (+5% better hashrate than what I'm at now, while also shaving almost 10% power consumed ) . But AMD settings reset themselves from time to time, which is hugely frustrating
