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.

thanks for the info. this is exactly what I am doing. it does provide extra peace in mind knowing that my odds of having silent corruption is further reduced by doing such monitoring.
