Thank you! I just tried the last EFI it works but monitor is not waking up when it enters saving mode.The intel HD 530 still showing 1536mb and the weird ram amplified size :lol:. What is the advantage of setting the DVMT prealloc in this machine? There is no option in this desktop's bios to adjust that.

Is the RAM showing and working correctly in Windows or Linux?

There's nothing in the config.plist that would screw with the RAM.

On many OEM systems, the DVMT prealloc settings are hidden and need to be configured in Grub shell. In my experience, setting DVMT prealloc is more stable than using workarounds in config.plist. It may even get your wake from sleep working.

Ram is accurate in Linux. Will dig in the DVMT if that is the only way to fix the waking. Thank you!

ZIP.... it was easy:banghead:
Thank you so much - after SO LONG - I finally found an EFI to boot up my 7040 SFF (yours) -- as is into Catalina - I'm finding the bluetooth/usb buggy but I think I read something about that earlier in this feed - this was so awesome to experience after almost giving up - thank you again !
