1- you need the latest kernel patches from here, not tested on 10.15.7, so may or may not work https://www.insanelymac.com/forum/topic/335650-kernelandkextpatches-1013x1014x1015x-x99x299/ 2- not sure,but usb should work. Make sure you update clover, as well as update to latest kexts. Also make...

Attached is one for 10.15.5, you might need to generate a new serial number. And you'll need change the video card id for your card as I have a Tonga card. Also you have a different CPU, so it may not work for you.

I have upgraded successfully to 10.15.5 using the same configuration with the latest clover and kext versions

I haven't tried with the raid, but I'm not surprised it isn't working. You'll probably have to do some searching to see if it's possible to get the drivers for it under OSX. I have usb 3 hubs in the systems properties and get about 50 -60 Mb/s to an external WD Elements SE drive. I don't...

This EFI enables XCPM in 10.15.4 with my xeon e5-1620v3.

How did you fix it? It’s possible That config file I posted for 10.14.6 may not work with latest clover and kexts as it’s quite old. I would use the EFI folders I posted for a matching 10.15 version install instead as there shouldn’t be any version issues. Have you got the latest bios firmware...

try 10.15.3 with the last EFI I posted or see here for some others that might work with your cpu https://www.tonymacx86.com/threads/x99-macos-catalina-10-15-2-kernel-patches.288451/page-3#post-2072410 . You will need to change the ati device id the match your graphics card, you’ll need to search...

Clover is working without the need for xcpm kernel patches in 10.15.2, 10.15.3 and 10.15.4 beta see here: https://www.tonymacx86.com/threads/success-catalina-10-15-3-hp-z440-workstations-e5-1660-v4-sapphire-nitro-rx-5700-xt.290401/page-3#post-2071066

Here is the latest EFI working in 10.15.2 and 10.15.3. Note that the xcpm kernel patches are no longer needed to enable xcpm, so hopefully this will work in newer versions of macOS as well. All that was needed for my Haswell Xeon E5-1620 V3 was to enable plugintype in clover!

I was able to remove nullcpupowermanagement.kext and turn off kernelPM, KernelXCPM and it's still working with full turbo boost for me after sleep, without any kernel patches. I think the ssdt pm and plugintype are enough for my Haswell Xeon. I've attached my clover EFI.

It now works on mine in 10.15.3! Thanks!! Did you make the ssdt pm?

That's good and you seem to have turbo boost to 3.8Ghz too. Does it keep working after going to sleep? I checked the EFI you posted, and you have both xcpm kernel patches for 10.15.2 and nullcpupowermanagement.kext. I don't think the kernel patches are needed for your processor, because they...

nothing yet. Are you going full turbo boost under high loads?

You still have the xcpm patches ("Add 5 patches from the author), so that's no different than how we do it in clover now (mine has working xcpm in clover already), but you will still need new patches for 10.15.3? After v5.4 opencore is supposed to be able to without any patches, but it seems...

Does your xcpm work? You need to use Intel Power Gadget to check.

New patches are needed for 10.15.3, I've attached the kernel if anyone knows how to do it. Opencore is supposed to make the patchers obsolete, but I can't get xcpm even in 10.15.2. I've attached my opencore EFI if you want to try that, although it's likely you'll need to make your own SSDTs.

I’ve been unable to get cpu power management working using opencore 5.5 in 10.15.2 without patches? Works fine using your patches in clover. Is there something specific we need to do to get XCPM in opencore?

Make sure you use the initial config file I posted from Mojave. The one in the EFI folder I uploaded is for Catalina. My bios is the latest version and using default settings

I now have my HP z440 Running Catalina 10.15 and works perfect including speedstep and turbo Updated EFI folder attached
