Overclock a RX570 on Hackintosh?

[StefanIsBuilding]

How is that possible? I want to overclock my GPU for some test, but I could not found an easy way to do this. Is the only way to tweak the parameters in Windows and and load the parameters into the BIOS of the GPU with POLARIS?

Is there any chance to tweak the GPU from MacOS?

No, not by Tools - on the fly - running Mac OS. Other than VEGA or V II where you can use some Mac Tools to generate OC/Undervolting and inject those by Clover into the AMD Driver table.
BUT you can OC/ Untervolt (at least little UV is recommended to avoid to hot gpu ? trottles = slower!) by edit the Video Bioas unter Win and reflash that BIOS with your OC/UV values.
SBR Polaris Bios Editor (WIN)
You also need: https://www.techpowerup.com/download/ati-atiflash/
and perhaps GPU-Z to check changes (and save orig. BIOS before edit!!)
I did that with my RX 460 (including unlocking shaders )and it worked.

You may need (after flash new BIOS) https://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher If WINDOWS AMD drivers won't load ( Code 43 )after a bios flash, use this tool-
HINT: With AMD win tools (Wattman etc.) you can check / change OC Values / UV before you flash them-
