Anybody out there have a working EFI for an MSI X399 Carbon with a 2990X threadripper? I can get the 2970 to work but the 2990 freezes and reboots at the login screen when using the same efi. The only difference is the adjusted core count in the kernel patches. Using OC 0.8.3.

Have you checked if you have a SSDT-CPUR.aml installed? The values in there may also need adjusting to 64 threads since you have 32 cores.

Try to disable SMT in bios
Ok, no success so far. I upgraded to OC 0.8.4 and have tried to boot Ventura with the attached EFI. I have an MSI Carbon X399 board with an 2990WX cpu. I've tried iMacPro1,1 and MacPro7,1. The computer boots to the login screen then freezes and reboots. I have another computer exactly the same with a 2970WX and it boots Ventura no problem using the same EFI (adjusted the core count). I'm stumped.

Have you added AppleMCEReportDisabler.kext to your build? This is an important kext for AMD Ryzen users on Monterey.

Yes. This EFI will boot Monterey but not Ventura.
Okay. To boot Ventura you'll need to use these settings:

1) -lilubetaall -no_compat_check in NVRAM boot-args

2) Enable these in Booter > Quirks
SetupVirtualMap
EnableSafeModeSlide
SyncRuntimePermissions
ProvideCustomSlide
RebuildAppleMemoryMap

3) Enable these in Kernel > Quirks
PanicNoKextDump
DisableLinkedItJettison
PowerTimeoutKernelPanic
ProvideCurrentCPUInfo

4) Enable
Lilu.kext
Whatevergreen.kext
AppleALC.kext
VirtualSMC.kext
AppleMCEReporterDisabler.kext

ALSO:

You need to change/add MaxKernel to 22.99.99 on most of the Kernel > Patch settings

No need for this with new versions of your Kexts and a MacPro7,1/iMacPro1,1 SMBIOS.

2) Enable these in Booter > Quirks
SetupVirtualMap
EnableSafeModeSlide
SyncRuntimePermissions
ProvideCustomSlide
RebuildAppleMemoryMap
If Monterey was booted, these values are most likely already set correctly to their hardware. Some systems need SetupVirtualMap disabled.

3) Enable these in Kernel > Quirks
PanicNoKextDump
DisableLinkedItJettison
PowerTimeoutKernelPanic
ProvideCurrentCPUInfo

4) Enable
Lilu.kext
Whatevergreen.kext
AppleALC.kext
VirtualSMC.kext
AppleMCEReporterDisabler.kext

Not if their AMD Kernel Patches are up to date (which they are in their EFI).

Did you clean install or upgrade to Ventura? Try clean installing. I would also suggest making your own EFI with the Dortania guide.
