New ASRock B450M-Pro4 does not keep time

[Frandesktop]

Hello,

I bought an ASRock B450M-Pro4 to pair with a 2200g and the time does not keep itself. I changed in UEFI twice and it keeps losing it.. Is it a defective motherboard?

Change the CMOS battery, the coin cell between the 2 PCIe slots

You mean it doesn't save the overclock or any settings you set in the bios?

I didn't try to overclock, could the problem be caused by me unplugging the PSU and pressing on on button to discharge the electricity then plugging it back in? (I needed to open the case to insert a cable there)

But it's a new mobo.. or it was old sitting for a long time in the warehouse?

I would describe what you mean when you say the board doesn't keep.

I will give it another chance because perhaps it happened after I unplugged the PSU

The CMOS battery is dead, when you unplug the motherboard the CMOS is the only thing powering it to maintain the clock/BIOS settings.

 

That is why when you really want to clear every single setting in BIOS, you remove the CMOS battery.

Bios will tell you battery voltage. Should be 3.3v. Under 3v replace it.

 

Windows syncs time with bios. Set your time in windows to correct region and double check in bios after a restart.
