If you had damaged the ME firmware, you would not reach coreboot or any other firmware - the blob is signed
If you had damaged the NIC firmware, ethernet would probably be broken, so that's clearly defined.

refining the wiki would be a good thing to do

That's RAM _clock_ not data rate which is double the clock rate (-> DDR) - you're not any worse off than with the original firmware.
