After bios mod with Polaris Pro, how can I find best OC?
because today I mod my Sapphire RX470 Nitro+ 4GB Elpida and I set Memory Clock 2050 and Core Clock 1180 showed me 30Mh/s but afater while showed gpu overclock problem!

I would like to know what's the best OC for AMD cards?
Because I have different GPUs
