ECC memory is fine for real-time audio

No, you will not notice the performance hit from ECC memory in real-time audio work.

The overhead from ECC is maybe 1-2% in memory bandwidth. Audio production rarely saturates memory bandwidth anyway — your bottleneck is usually the CPU trying to process plugins at low buffer sizes. That tiny latency hit from ECC is invisible compared to what your DAW is already doing.

What you will notice is the stability. Memory errors cause pops, clicks, or full crashes. In a long mix session or live performance, ECC catches those errors silently. Non-ECC memory just lets them through. I’ve had a RAM error corrupt a vocal take I was proud of. Never again.

If you’re building a workstation for audio and you can get ECC support (usually requires a server-class CPU and motherboard), do it. The “performance hit
