Hey paparotto, cheers for the tip on the BIOS update I'll have a closer look.
I did create my own amd-usb.kext but ended up disabling all the ports on XCH0 to do so. I might have another look in the future but otherwise it's okay for now.
The kext I used was killXHC0.kext, I got it from here...
Hey, I believe this is a reporting problem - I have 2933MHz ram and have 1467MHz reported in OSX. The number seems to show up as half what you see in the BIOS.
Having said that I am actually not sure - the BIOS reports correctly (I'm using XMP) and the machine works pretty fast.
Disabling all XHC0 ports seems to have fixed the issue, my computer now sleeps and wakes!
Only caveat is that it takes 20 seconds or so for the sleep to kick in (at which point the fans/lights shutdown)
Bit of an update, I haven't got sleep working yet but have tried the following:
- Mapping out ports for XHC0 controller
-Using trulyspinach's AMD CPU Power Management
- Disabling wake on USB
I haven't been able to map out my other USB controller PTXH, will try this next..
I've got a mostly successful build now, the specs are:
Ryzen 5 1600 cpu
MSI B350m gaming pro motherboard
RX 5700XT gpu
16gb Corsair 3200mhz ram
500gb samsung 860 evo ssd
The main thing I haven't been able to get working is sleep/wake, does anyone know how to...
