Also, what would be absolute max voltage for GPU and memory, with the stock cooler, for daily use considering that on stock clocks and voltage the absolute max temp I'm seeing in DOOM with Vulkan is 72 ~ 73°C?
Well the ASIC quality it's just a reference of the pure quality of the GPU Chip sorry my english it's not good - But in basic when you have more ASIC quality you need less voltage, but it's more sensitive to voltage changes, so probably you can't rise too much the overclock to win stability, for example if you get at stock voltage 1350 Mhz, it's probably you not win stability rising the voltage to get more frequency, but with the stock voltage you will have more freq than lower ASIC cards, and by the way it's less hotter so, with air you can work fine.-
About the stock cooler, that video card have a good cooler, my recommendation it's use the "RX 480 unlocked bios" you can go to 1.40v - In my personal opinion the max voltage for air cooler its 1.25v ideal 1.20v the VRM will not be very hot, but with that asic may be you can get decent overclock with less voltage than 1.20v.-
You can put the unlocked bios, and just overclock using GPU Tweak II, to get the mem freq, core and voltages, the mem voltage left it original 1000 mv no difference in stability you can get 2150 / 2160 Mhz without memory errors (HWinfo will show you that) - When you finally have the freq of Core, Mem and voltages of core, you can set it in a custom bios.-
The problem about custom bios it's not signed, so you need to patch the driver and all that stuff, the "unlocked bios" it's signed by AMD, so you don't need to patch the driver, and you can overclock by software.-
The last thing you must check it's your stock voltage with original bios in stage 7, some GPU have 1100 mv and others have 1150 mv, check that, because usually the overclock software detects 1150mv and if your video card is 1100 mv you will thing you are getting 1200 and in fact you are in 1150 mv.-
But always check the Real voltage in load (games, benchmarks, etc) with GPU-Z.-
