Remove OsxAptioFix2Drv-64.efi, you already have AptioMemoryFix.efi ( they are mutually exclusive) in /EFI/Clover/drivers64UEFI.
Seems all the drivers have different dates. Why not just install latest Clover v4844
That's normal in Hackintosh for those brief seconds. Lilu.kext + Whatevergreen will remove some but not 100%.
If you boot with verbose mode, you won't see it, so take your pick.
Lots of patches are now included in latest Clover so no, no need to patch DSDT.
You'll need to remove NullCPUPowerManagement.kext and enable AppleIntelCPUPM in Config.plist
Add Whatevergreen.kext <- for graphics
and ACPIBatteryManager.kext <- for Battery status
Not sure you'll get HDMI / HDMI Audio working with VoodooHDA
Replace it with AppleALC.kext and use layout-id 12
Might need to add FB patch for HDMI video as well
