The rated speeds are not as high, but ECC memory can be overclocked just as non-ECC; memory overclock support is mostly up to the motherboard. I have some DDR4-2666 ECC overclocked to 3200 MHz with slightly tighter timings on TRX40.

Good point. I guess what I meant to say is that ECC memory is not marketed for greater than JEDEC speeds.
