3 Things to Know About ECC RAM Latency

The performance difference is tiny At the same frequency and timings, ECC RAM adds only 1–3 nanoseconds of latency. That translates to a 1–2% real-world performance hit.

You won’t notice it in everyday use In games, rendering, or heavy multitasking, the latency is imperceptible. For basically everyone outside a lab, it’s a non-issue.

Don’t let latency stop you from using ECC If you need ECC for stability in servers or workstations, the latency trade-off is negligible. Just avoid mixing ECC and non-ECC on the same motherboard.
