B450M Pro4 Build issues

   You'll need at least one stick of memory in the machine to get to the BIOS.

I don't recall hearing beeps at startup.  I'm not close to the machine at the moment, unfortunately.

	Success I removed the battery and re-installed it. Add x1 stick of ram, and away it started. System up and running now.

	Hello kschendel, I initially had x2 sticks of Kingston HyperX Predator (16 Gb) on the board, but when it didn't start I removed them both and started the board with only the items I listed. Should I hear any beeps?

	What memory? sounds like a memory training loop to me. Try individual sticks in all the slots to see if there's a stick/slot combo that works. You might also try complete BIOS reset, that's what it took to make my Pro4 M behave itself.

	Hello, I recently purchased an Asrock B450M Pro4 and am having an issue with the build. When I push the start button, the CPU fan starts up for about 20 - 30 seconds then stops, and after 2 seconds it restarts and continues this loop. I have tried - x2 550W power supplies which have been connected to the motherboard. (x1 is brand new and the other from an older working computer), - x2 new Ryzen CPU's (Ryzen 3600 & Ryzen 2200G), CPU fan connected - Speaker connected to speaker header - Power switch connected to system panel header - Motherboard is on anti static bag No beeps are emitted from speakers Is there anything else I can look at before I return the motherboard to supplier to check or replace?
