X570M Pro4 Deep Sleep

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello,

since weeks (or months), I got the problem of resetting BIOS from time to time and finally was able to figure out the reason. As soon as I enable Deep Sleep S4+S5 to have my LEDs turned off while the PC is turned off, after some time, the BIOS will reset. Usually over night, when PC was turned off for some hours.
I am now noticing it, when the PC "double-starts" like press on, loading, going off, going on, Windows starting with reset BIOS.

That means, my RAM XMP Profile is resettet and all my fan tuning goes back to loudness war. Never had this kind of problem before with any other manufacturer. But also this is my first AMD since years, so...

Is this some kind of hardware defect and I have to send in the mainboard or did ASrock just  up the BIOS and I can't do anything against it? Sadly, the X570M Pro4 is the only useful mATX X570 Board on the market.
Latest BIOS (3.30) is flashed already.

	Dear John, Thank you for the posting. Regarding the problem of BIOS settling reset, we would suggest replacing a new CMOS battery to try. Thank you, Best wishes, ASRock TSD
