Question 5 beeps from Gigabyte Aorus Pro Z390 - but it boots fine

[Horrgakx]

Sometimes, maybe 1 in 8 cold boots, I get 5 beeps (in less than 3 seconds) from the motherboard. It boots into Win10 fine and doesn't throw any error messages in Windows.

I've looked at some other posts on this forum but they don't seem to apply to this issue. Does anyone know what it is?
