ECC is overkill for compiling on a 5700G.

No. For compiling code, you won’t see any practical benefit from ECC memory on a Ryzen 7 5700G.

The 5700G supports ECC only with a Pro or certain non‑consumer motherboards, and even then the odds of a single‑bit error corrupting your build are astronomically low. Compiling is CPU‑bound, not memory‑integrity bound. Your time is better spent on a fast NVMe drive or more cores.

If you’re running a file server, a database, or a machine that does months of non‑stop calculations, sure, consider ECC. For a home office compile box, it’s a solution in search of a problem.

Save the money and put it toward a better cooler or a second monitor. Future you will thank you.
