Question Asus M5A97 Motherboard with FX 8300 Cpu and 24GB Memory taking a minute to power up

[thomastt371]

Ive recently purchased an asus M5A97 motherboard and cpu bundle (FX8300} which i have installed with 24GB memory..the Boot up time seems like an age after pressing power button even before the cpu fan starts!..None of my other systems which have asus boards and amd pcus all boot almost immediately.I have made sure fast boot is enabled and have disabled secure boot as i use Linux operating systems..could there be something seriously wrong with the motherboard memory or Pcu.I have an adequate PSU 500gb Can anyone shine some light on this problem any help appreciated Michael

Is this a new OS installation?

That's more typical of a DDR5 system auto training RAM on a brand new system.

24GB seems a slightly unusual amount. What do you have installed? 2 x 8GB + 2 x 4GB?

Are the DIMMs all the same speed? They probably have different timings and the BIOS is trying to sort things out. I hope at the very least they're matched pairs and not four random DIMMs.

Try removing the 2 x 4GB and see if it boots faster with 2 x 8GB.

You might have "odd" pairs installed, i.e. an 8GB in Channel A and a 4GB in Channel B. This would certainly cause the BIOS some headaches at startup. Some weird combination of Dual and Single Channel working.

Try the 8GB DIMMs in slots A2 and B2 on their own. Then add the 4GB DIMMs to slots A1 and B1.
