ECC RAM won't help your video encodes.

Probably not. You’re overthinking this.

ECC (Error-Correcting Code) RAM catches and fixes single-bit memory errors. Those errors are incredibly rare on modern consumer hardware—like a few per year under normal use. Video encoding is mostly a sequential, compute-heavy task where the occasional flipped bit in a frame might cause a single corrupted pixel or a brief artifact. It’s not going to crash your workstation or corrupt your entire project.

The bigger risk to 24/7 stability is heat, power fluctuations, and bad drivers. A $40 air cooler and a clean Windows install will do more for uptime than swapping to ECC memory. Plus, ECC typically requires a workstation motherboard and a server-class CPU (like Intel Xeon or AMD Ryzen Pro), which costs more and might even reduce performance for encoding tasks because of lower clock speeds.

Unless you’re running a render farm where a single corrupted frame costs thousands of dollars or you’re processing financial data that needs absolute correctness, you’re better off with fast, reliable non-ECC RAM and a good overclock that stays within voltage limits.

Spend the money on a better CPU cooler instead.
