Unbuffered ECC RAM on non ECC Intel board

Hello guys,

I want to upgrade my girlfriends PC, I want to get her a "ASUS PRIME B660M-A D4-CSM -mATX Mainboard -DDR4 -Sockel 1700" and still have 32GB unbuffered ECC DDR4 RAM laying around.

Can some tell me if Intel is going to make problems here? I heared that some boards have problems with it.

Thanks in advance.
