r/ASUS on Reddit: Can anyone point me towards a list of Q-codes?
April 21, 2024 -
I recently completed a new computer with a StrixX670E-E and, after a short time, it failed to boot and showed a memory error code.
I contacted support, sent it back, and they sent a replacement.
I reassembled my PC and, while it starts, it shows a series of Q-Codes (most appear around memory again) and I am hoping to try and figure out what is going on and, if possible, fix it before it breaks again.
However, I am unable to find a comprehensive list of codes and can only find people talking about them in various forums with generalized and surmised meanings. It would be really nice to have something more official (and which I could use to try and figure out how to diagnose the underlying issue and try and solve it).
Can anyone help me find one?
