Q-Code 23 on Maximus VI Hero - Republic of Gamers Forum - 406454
I've got a Crosshair VII wifi, have had it for a few years now. Always worked fine.
Last week i upgraded from a 3700X to a 5800X3D (i flashed the most recent bios, 5102, a few weeks before that), which worked fine for about a week. Suddenly, this morning, the system wouldn't boot, giving me code 23 on the Q-led.
I took off the power, let it drain, then turned it back on and worked again.
However, the bios did complain about not being able to apply OC settings (despite me only having set a -0.1v offset undervolt, which worked fine for a week), so i set it to -0.075 just to be safe.
I'm finding conflicting messages about what the actual meaning of code 23 is, and no official documentation. Most worryingly i find a few comments about it meaning possible cpu damage (pins), but that doesn't really make sense as the system is otherwise perfectly stable under any load (though that's me also being hopeful).
Does anyone know what code 23 means, or has access to the full documentation about q-codes? I have no idea where to start troubleshooting this.
EDIT: I've received a response from ASUS support.
Q-code 23 means 'general error', usually pertaining to an electrical contact. Reseating (and checking) RAM or the CPU may be necessary, but it can also be a BIOS error or an overclock/undervolt problem necessitating a BIOS reset. Sadly there's no way to specify it further according to them.
