Difference is whether memory is retrained or not. For dran related items it is retrained. For other it is not.I have found some settings that are pretty stable on my rig.
Days of testing (memtest, ram test, cinebench, aida), gaming, programming with IDEs, code compiling.
1.360V VDD/VDDQ/TX VDDQ
I can't crush my PC with that settings...
But I don't understand why these settings are so difficult to boot.
Once the PC is able to boot with these settings is super stable, I can reboot it without problems and live with these settings.
But as soon as I change something in BIOS, even to simply loose a timing from C36 to C40, the PC hangs on "DETECT MEMORY" error code 28.
After various try and retry, like setting C38, then C40, then C36, after a lot of try I can boot with the stable settings.
this does not happen if with the same settings, I select 5.0GHz and 5.2GHz.
5.0 and 5.2GHz are less stable than 4.8GHz during testing but much easyer to boot with.
How this is possible?
I'm not an expert but this seems something that should be fixed by Asus.
PS: Using 0070 and 9901 BIOS
