Hello José,
i Hope u’ll read my message
I found better oc settings
GPU 0 maximum memory is 2300 and hashrate highly decrease when i set to 2400
Others GPU are fine at 2400 and maybe i can increase ( might be the “lottery” )
I stick with this settings 1 day or 2 to see the stability
You can improve those settings by increasing memory clock +100 each time and see what happened
Hope this will help
Regards
Lee
