Your OC config is incorrect in several instances:

  1. you opted for XCPM on this Ivy Bridge laptop and that no longer works (well) afaik:
    • Remove the AppleXcpmCgfLock quirk from the Kernel section only to keep the AppleCpuPmCfgLock quirk
    • Remove the SSDT-PLUG.aml table from your OpenCore EFI/ACPI folder and replace it by your CPU-specific power management SSDT table (that you can rename SSDT-PM if you wish) generated with good old generator script from Pike R Alpha. It's the best solution for Sandy and Ivy Bridge laptops. Then, in your config's ACPI section, replace the defunct reference to SSDT-PLUG by the name of your generated CPU PM SSDT.
  2. In your OC config's Device Properties section, you need to add the following properties against your iGPU to reduce framebuffer memory size from 16MB to 8MB (or you'll get glitches):
    • framebuffer-patch-enable    1           NUMBER
      framebuffer-fbmem           00008000    DATA


  3. Not sure you need SSDT-HPET table.
  4. Not sure you need -wegnoegpu boot arg in NVRAM settings. Does your E5430 have a dGPU that needs disabling?
  5. alcid=1 seems incorrect to me if, as I suspect, your E5430 is fitted with same IDT audio codec as the E6x30, in which case the correct layout id is 12 (0x0C).
  6. you did not say which macOS (or OS X) version you're trying to install but you've set csr-active-config NVRAM parameter to 3. This was fine for older OS versions but more recent versions would typically require different values. It really depends on what you want to disable in SIP

Check the OC pack I had posted in my E6230 Big Sur guide and build from it.
