ECC overhead is negligible for rendering.

No, you won’t see a meaningful speed drop from the error correction overhead.

ECC memory does add a small latency penalty—usually 1-3% in synthetic bandwidth tests. But for heavy 3D rendering, the bottleneck is almost always crunching through the scene, not memory latency. You’re waiting on the GPU or CPU cores, not the RAM’s error-checking logic.

What you will notice is having double the RAM. 16GB is tight for complex renders—swap thrashing kills performance way more than ECC ever could. Dropping in 32GB ECC means fewer memory bottlenecks, less swapping, and far fewer crashes from silent data corruption during long renders.

The stability win alone is worth it. A single flipped bit in a 12-hour render is a nightmare. ECC catches that.

Stick with ECC. Future-you will thank present-you when that render finishes on time and uncorrupted.
