> do they consider the memory is faulty when there are correctable errors? It depends on the frequency. Occasional CEs are somewhat expected (on a large enough scale) and one can live with them, after all that's what ECC is for. When CEs start happening frequently on one machine, most likely a DIMM is going bad and will worsen over time, so one should replace it.
