Mojave 10.14.6 – RAM Upgrade from 32GB to 64GB -> Bootloop

No it is not possible to downgrade from the F12 bios. The new bios contains some fundamental fixes, which Gigabyte have set so they can't be unfixed.

No I don't know where the items would be in the F12 bios. Did you try using the F2 key and accessing the bios in Classic mode?

Hi All,

Recently i discovered, that my hackintosh-motherboard (Z390 Aorus Pro Wifi (rev 1.0)) supports a total of 128GB RAM instead of 64GB.
Therefore i bought 2x32GB Corsair DDR4 3200MHz RAM-Moduls to upgrade. At the moment i have installed 2x32GB Corsair 3200MHz + 2x16GB Corsair 3000MHz.

After installing all the modules my computer seems to get stuck at the bootloader and heads back to rebooting.

I've upgraded the BIOs of Z390 Aorus Pro Wifi to the latest Verision "F12", but couldnt figure out what setting i messed up. here is what i changed from Load optimized defaults:

Windows 8/10 Features: Windows 8/10 -> Other OS
XHCI Hand-off: Disabled -> Enabled
Internal Graphics: Auto -> Disabled
RC6(Ender Standby): Enabled -> Disabled
CPU Fan Control Mode: Auto -> PWM
Extreme Memory Profil (X.M.P): Disabled -> Profil1
System Memory Multiplier: Auto -> DDR4300

Attached you'll also find my EFI-Folder as .zip. Maybe the bug is in there.

As always thank you for your support!

Best, othernoise

Did you ever figure it out? I'm having a similar issue.

Best solution is to not mix RAM modules of different speeds. Use matched pairs/sets when possible.
