Hi everyone first time using this miner and I'm trying to find the best settings for my cards to run nice and stable yes efficiently

I have the rx480  8gb sapphire cards
I have the rx470  4gb sapphire cards
I have the Vega 64 Red Devil cards

What are the best settings to use when mining HEAVY (ALLOY)

As in Clock settings / power settings / and miner settings
Thanks in advance
