I am using a nvidia Kepler card quadro k420 which should be natively supported.

mount efi driver and delete EFI folder in this driver and replace with attack efi folder below. i hope it can work for you.

thanks for the folder.

I tried with it, it got the error just like with my own configuration "AMF: Only 248/256 slide values are usable! Valid slides: 8-255
+++++++++++++++++++++++"

I googled the error, someone said it is a new issue in Catalina of Clover, people suggested to use OpenCore instead of Clover, not sure if that really the case.

sory i don't know but it work fire for my previous of quadro M4000. now i uppload worked EFI for AMD graphcis boot with some change boot parameter for nividia. if you can install success contact to me. i can folow you for nividia install drive.

thanks again for the help @khoaha19 , this time the installer was able to boot the machine correctly. but i found it can't format the SATA SSD in the installer Disk Utility which is pretty weird. the error of that is
"unable to write to the last block of the device"

I swapped to other SSD and also tried other SATA port, still same..

first time you cannot erase one partition. backup your data and erase whole disk by disk utility and repartiotion.

Yes is normal as 3200mhz

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

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 should not do anything in 10.15.3, it's probably just nullcpupowermanagement.kext that makes it work. Can you disable the xcpm patches and see if you still get boosting to 3.8ghz? If so and still works after sleep, I might upgrade my z440 to a e5-1660 v4 so I can stop worrying about kernel patches.

thanks

Yes you are right. don't need any kernel patches. you can use below option for power manager!
1. not use acpi ssdt pm + faceCPUID(0x0306F2 on config.list) + nullcpupowermanagement.kext
All work with sleep but CPU Freq max is 3200Hz
2. use acpi ssdt pm + do not use fafceCPUID + nullcpupowermanagement.kext
All work with sleep and CPU Freq max is 3800Hz
I have try all from 10.15.2, 10.15.3, 10.15.4 beta.
Below the picture is cpu pm after sleep on 10.15.4 beta.

I will attact final my EFI(with acpi ssdt pm patched). All work fine with my Z440. use it you can stop worrying about kernel patches.

Note: do not install 10.15.4 beta now. prefer HDR do not working true.(it proplem from apple not on hackintosh so you can wait for apple fix it on new version).
