Initially, yes. A panic move when AMD brought out their 40 MHz 386. It worked, got popular and later on the 486SX was manufactured separately with a smaller die and no floating point. As for the ECC support in Ryzen CPUs, as I understand it it's a bit of a mess. Sure the CPUs support it but if it's not validated by motherboard manufacturers, how do you know it actually works reliably?
