Do you remember which version of setup_var you used?...
I can confirm 0x5C1 for Z390 Aorus Xtreme on BIOS Version F5, too. Nice that you made a tutorial, a little late for me, but I appreciate someone helping the newer generations. We have to apply that trick on every BIOS-Update, I suppose (unless settings are not reset, but I suppose that almost never happens).
The third version (setup_var_3) handles this issue by ignoring the variable that returns fewer bytes, and applies the change to the larger Setup variable.
That's what the AptioMemoryFix README promises.For me both options work fine (and have worked fine even before CFG-Unlock), so I dumped the other memory fix quite early and turned to AptioMemoryFix. But without EmuVariableUefi sleep and shutdown get...let's say funny
Even on the Designare Z390, AptioMemoryFix tends to work until we install a PCIe card other than the GPU. For example, as soon as the Fenvi FV-T919 WiFi/BT card is installed, AptioMemoryFix fails, but OsxAptioFix2Drv-free2000 continues to work.
Do you have a WiFi/BT PCIe card installed in your system?
