New RAM runs on values of my old one?

EDIT: Fixed! Thanks to u/NonXtreme, clearing cmos did the job. Also thanks to everyone else trying to help, it's really an awesome community.

​

Hey guys,

today I switched from my old 2x8gb 3000 dimms to 2x8gb 3600. The new RAM is validated with the motherboard via the QVL list, I enabled D.O.C.P (it shows 3600 and correct timings) in BIOS. Yet somehow if I check the numbers in BIOS or CPU-Z, my RAM is still running at 3000mhz 16.20.20.38 rather than 3600mhz 18-22-22-42. Any ideas?

Some info on the specific hardware:

Mainboard: ASUS TUF B450 Plus Gaming

CPU: Ryzen 5 3600

Old RAM: Corsair Vengeance LPX (CMK8GX4M1D3000C16)

New RAM: Corsair Vengeance RGB Pro (CMW16GX4M2Z3600C18)

Any help is greatly appreciated.

Is DOCP set to run at 3600MHz? I would verify that.

It is, also edited the OP to make it more clear.

Manually set all the timings and speed

Seems like it doesn't work for me, but I'm new to this stuff. Whenever I set timings and speed manually in BIOS to 3600 18-22-22-42, it still runs at 3000 16-20-20-38. Do you know the ASUS UEFI BIOS by chance and can give me a quick instruction on the steps?

i do know the bios, something to check first is the ram voltage, is it running at at 1.2 or 1.35 volts?
