Why 25%, shouldn't it be 12.5%? 8 ECC bits for every 64 bits. | ||

DDR5 ECC RDIMMs (R=registered) have 16 extra bits. From the specifications for Kingston's KSM64R52BS8-16MD [1]: > x80 ECC (x40, 2 independent I/O sub channels) On the other hand ECC UDIMMs (U=unbuffered) have only 8. From the specifications for Kingston's KSM56E46BS8KM-16HA [2]: > x72 ECC (x36, 2 independent I/O sub channels) Though if I remember correctly, the specifications for the older DDR4 ECC RDIMMs mention only 72 bits.
