I don't think the battery is flat. When booting into the BIOS after all the restarts the XMP Profile is still enabled.

Oh sorry forgot to mention. BIOS is also at the current available version.

Hi, So I build a PC for a good friend of mine some while back. Aorus X570 Elite, Ryzen 7 3800x and at the time 16GB TridentZ @ 3200Mhz. Now she does a lot of 3D modelling and simulation, for that we wanted to upgrade to more RAM but still be affordable. So we bought some "G.Skill DIMM 64 GB DDR4-3600 Quad-Kit - CL18-22-22-42" Enabling the XMP-Profile in the BIOS did nothing for us. Even writing the timings and frequency in manually did not help. Every time after saving in BIOS the PC posts 3x and after that in Windows itself the frequency falls back to 1066Mhz. Even the timings change to CAS 15. I tried raising the voltage to 1.4V but that did not help either. Also with the same timings and 1.4V @ 3200Mhz did not work. I am currently out of ideas. I hope someone can help me. If you need further information regarding the rig please ask! Thanks!
