This motherboard has no onboard speaker. There is a 4-pin speaker header for user to add additional speaker. There is no beep sound from the additional speaker when the system boots well, if the memory module, CPU, graphics card etc be installed not well, there is some beep sound from the additional speaker to remind user to re-install these devices.
