How much memory is lost when you enable ECC? That's why consumers will disable it.
- adrian_b 3y agoNo memory capacity or memory throughput is lost in consumer motherboards when enabling ECC. You just need to buy ECC UDIMM modules, which, especially for DDR5, are more expensive, up to 50% more expensive for DDR5, even if this price difference is not justified. Moreover, the ECC modules are never factory overclocked, like most non-ECC modules, therefore ECC UDIMM modules faster than DDR5-4800 are hard to find. Nevertheless, that has not stopped some users to overclock them manually. There are some embedded computers for industrial applications, with certain models of Intel Atom or Core CPUs, which support the so-called in-band ECC, which can be used with non-ECC memory, like LPDDR5. Only on those computers enabling ECC reduces both the available memory and the performance.
