Z690 Hero cycling through Q-codes while in OS, and it's not temperature

Level 7


I've been using a Z690 Hero for 2 months and everything is still running fine, except that the Q-codes now shows weird behavior since few days. It is running fine until end of boot, then it displays the CPU temperature as expected, and then few minutes after, with no apparent reason, it starts to cycle through few error codes : 01-14-(sometimes 00 which is apparently not used according to the manual).. Each code staying 1-3 minutes every times. One time I also saw 27-28 cycling more rapidly, which are also not used according to the manual. I've already verified that the bios is correctly set up for the Qcodes screen to display CPU temps.

Is it something I should be worried about ? Otherwise my computer appears to run fine as usual.

Thanks for helping !

Hi @alchemino 

Can you confirm if this happens if the Q-CODE display is at default (to display Q-CODE) and not temperature? It's not something I've come across before.

Thanks for answering. The issue is for some reason not always present, so it is kind of difficult to reproduce. I have just set the display at default and for the moment it appears to run fine but I will update if it goes wrong again.
