Ryzen 5 two beeps at startup but boots fine

There are a number of reasons a system might beep more than once but still complete
POST and boot normally. In every instance it is some part of the POST process that
took longer than the system expected. Basically, the system begins to beep a POST
code, then that code clears and POST continues.

Typically it's either a display taking a bit too long to reply to the system, this
can cause more than 2 beeps depending on the length of the delay, or an XMP/EXPO
profile that takes longer than it should to pass POST testing. Another thing I
have seen cause multiple beeps is an old, dying or slow mechanical HDD though
this is rare these days.

In all cases it is only a problem if it starts happening out of nowhere where
previously it did not. By out of nowhere I mean no changes to the system, including
displays, display cables, BIOS updates etc. In cases where the issue existed from
the first power on there isn't any cause for concern. It just means POST was going
too fast for one of your components.

In other words, it's only cause for concern if it is a new symptom.

As I said, unless it's something new that popped up it isn't cause for concern.
So long as the system boots reliably and there is no instability I wouldn't worry
about it.

DDR5 is still fairly new, DDR4 was way more problematic at a comparative phase.

Enjoy your build, no doubt a BIOS update will clear up the extra beep at some point
