Hi all,

I am deseperate with this config...

Supermicro X10DRH-CLN4 (C612 Chipset)
2x Xeon E5-2680V3
64Gb DDR4 2133 (4x16Gb)
GTX680
MacOs Catalina 10.15.4 + Clover UEFI

the system boot ok and all is work, but the cpu frequency get stuck at 2.5Ghz.

I have no turbo and power management at all...

I have generate a ssdt with ssdtPrGen command -> ./ssdtPRGen.sh -cpus 2 -target 2 -d 3 -l 48 -x 1 -c 1 (-c 2 and -c 3 tested also)

tested with multiples smbios MacPro6,1 7,1 iMacPro1,1 iMac14,2 Macmini7,1.... (system boot ok at all theses SMbios without ssdt.aml file)
tested with and without kernel patch here : https://www.insanelymac.com/forum/topic/335650-kernelandkextpatches-1013x1014x1015x-x99x299/
with and without -xcpm and -xcpm_ipi boot flag

I get kernel panic with all this methods

Without ssdt i have to enable generate Pstates and Cstates at clover to boot sucessfully.

I'm little lost with this problem..

can u help me?

Thanks.
