Nvidia uses ECC RAM on their GPU compute cards, an important consideration for serious HPC computing.

No, they don't. They implement ECC by re-purposing some of the existing RAM to hold the parity data. Enabling ECC reduces the usable amount of memory, and also can hurt performance. It offers some improved reliability, but it's nothing like a real server-grade memory system.
