    [TOOL] Radeon RX 5700 (XT) PowerPlay Table Generator (OC, UV, Fan Curve)

    Yup, just set all ZeroRPM flags to 1 and ZeroRPMStartTemperature to 60, ZeroRPMStopTemperature to 50. Also undervolt your GPU. Start with 1050mV and test how much you can pull it down until it becomes unstable.

    It's normal for the backplate to get hot.

    [TOOL] Radeon RX 5700 (XT) PowerPlay Table Generator (OC, UV, Fan Curve)

    I wouldn't touch fan speed on macOS since there is no way to get detailed temperature readout. I recommend reducing the GPU voltage for less heat. Doing so fans will become quieter as well.

    [GUIDE] Injection of AMD Vega Power and Fan Control Properties

    Polaris cards don't support PowerPlay Tables. I tried it together with others who use a Polaris card. There is a PowerPlay Table inside the VBIOS but injecting a customized table does nothing. So the only way to customize Polaris cards on macOS is by editing their VBIOS. There are plenty of...

    [TOOL] Radeon RX 5700 (XT) PowerPlay Table Generator (OC, UV, Fan Curve)

    I am not sure. I bought the Gigabyte RX 5700 XT Gaming OC which has heavy coil whine in Windows but not under macOS even on stock settings. I can only tell you that undervolting massively reduces fan noise under full load. Just experiment with it and you surely will find the perfect settings for...

    Jeesh, what kind of config is this? I am surprised your machine works at all. Please attach the whole Clover folder and provide an ACPI dump as well as a IOJones dump.

    PPT is injected as a device property.

    Of course. Look at the power consumption drop. Also gives you better performance since the card can hold its boost frequency. Without undervolting it does thermal throttling which results in framerate dips below the 60fps range.

    And this is the difference between gaming with stock settings and undervolting using a PowerPlay Table:

    [TOOL] Radeon RX 5700 (XT) PowerPlay Table Generator (OC, UV, Fan Curve)

    I did it again! With the release of the Navi drivers for macOS by Apple I bought a card and ported my popular PowerPlay Table generators to the RX 5700 and RX 5700 XT. Some might know I already did the same for V56/64 and Radeon VII. This tool allows you to change GPU, SoC and Memory Clocks...

    [GUIDE] Injection of AMD Vega Power and Fan Control Properties

    You don't need any PowerPlay Table. Fan control works OOB with macOS starting from 10.14.5. If for whatever reason you wanna use a PowerPlay Table though, do not use VGTab. First and foremost: That Kext solution is dirty and not even update proof. You override the AMD10000Controller using that...
