Post codes

I just installed a b550 aorus master and keep getting post codes 40, A0 and (F8 when running ryzen master) the post codes change every once and a while.

Is the thing misbehaving in some way?  Sometimes post codes are just reporting normal operation.  I don’t know what those codes mean but a code isn’t automatically bad

A0 : IDE initialization is started. (aka hard drive reading/activated)

40 : Doesnt exist? (cant find it on your motherboards manual: could possibly be CPU temp depending on Bios Settings)

FB/F8 : Reserved (system should be running fine just a status during boot i believe.

Ahh, odd it just didn't say it on the online manual for some reason. Maybe I was just blind. *although that is a normal code then, nothing alarming.

The dont list all codes sometimes. Not sure why though. 

 

Some codes will just kinda "be there" more for information than diagnostics.

 

When you start the system, all the codes are flashing away on the reader is just the board going through boot process. If the PC hangs on one of the codes, it doesnt mean that specific code is actually a problem, it's just where the pc stopped the boot sequence.
