ECC hardware vs software error correction: Software can't fix what hardware doesn't support

Software checksums or CRC can detect memory corruption after it happens, but they can’t correct it without redundant storage—duplicating every read kills performance and complexity. Without ECC hardware, errors are silent and unrecoverable. For critical work, get a board with ECC support like Rockchip RK3568 or x86 mini PCs; the RK3588 lacks it, and no software patch will fix that.
