Yes exactly. CSM off + Above4G on will only boot OpenCore 1 of 5 times randomly and with cold boot only.
So I use CSM off + Above4g off now and boots fine
Yes, I do have Windows in a separate disk.
Windows will not load with above4g enabled, CSM doesn't matter on or off
OK, finally working perfectly; sleep wake OK; I don't have anything to test TB3.
i5-9600K, RX 5700 XT Red Dragon w/SMBIOS 19,1, Apple M.2 WiFi card.
Here is my EFI OC 0.5.7 if anyone wants to use.
Only strange is the in BIOS. I can boot with CSM off + Above4g off OK;
CSM on + Above4g on OK ...
All the parts are new, memory is Crucial 2x16 3200.
PSU is Corsair SF750 (which is working because I used it in another system).
OK. I will try with an older set of memory to see if it's this.
Thanks
Hi,
I have the ASRock Z390 Phantom. It has an i5-9600K and Sapphire Vega 56.
I am trying to boot the UniBeast installer but no luck.
Maybe you can share a working EFI folder and BIOS config, BIOS is 4.2.
Thanks
Giannis
