How to quiet spammy ECC disabled logs [SOLVED]

My boot logs keep getting spammed by this message.

EDAC amd64: Node 0: DRAM ECC disabled.
EDAC amd64: ECC disabled in the BIOS or no ECC capability, module will not load.
 Either enable ECC checking or force module loading by setting 'ecc_enable_override'.
 (Note that use of the override may cause unknown side effects.)

I don't have ECC RAM. Who do I have to tell so they don't try to load the ECC module?

I already tried setting ecc_enable_override=0 in my kernel params, but it didn't do anything.

It will be removed with linux 5.5 https://git.kernel.org/pub/scm/linux/ke … 0f11f6314b

Don't know if this will work for you in the interim, try blacklisting via modprobe add

blacklist amd64_edac_mod

to /etc/modprobe.d/modprobe.conf

EDIT: kernel 5.5 doesn't stop the messages but reduces the information:

(this an older machine Asus M5A88-M; AMD-FX8350), restore blacklisting removes the boot message.
