It you have non-ecc ram, then the error would have to be an ecc corrected bit error/warning inside the cpu. If it is not crashing the machine then it was corrected. If you have normal non-ECC desktop ram it cannot be detecting an ECC error in ram since there is NO ecc bits in the ram. If it is just finding a single bit error every few weeks I would not be worried about it. When you have real issues the rate is often errors per second and/or multiple bit errors that crash the machine.
