Right, exactly. TCP protects us from data-corruption in network streams, and ECC protects us from data-corruption in RAM. I doubt any sort of software solution

Right, exactly. TCP protects us from data-corruption in network streams, and ECC protects us from data-corruption in RAM. I doubt any sort of software solution could practically compete against hardware ECC, even if it could be done it would presumably be disastrous for performance.
- knorker 6y agoThe best integrity checking is "end to end". The problem with non-ECC is that there are no "ends" that are trustworthy. I guess in theory some software could produce signed data in CPU cache, and "commit" it to RAM as a verified block. But the overhead would be enormous. Would you slow down your CPU by half in order to not pay 12.5% more for RAM? Hmm, I wonder what SGX and similar do about this.
