Sorry Geeky, an error that shows up in any module is an excellent predictor for a cascading error that will spread to other parts of the memory in due time and contribute to the instability of a computer in the mean time. An error indicates something electronically wrong with the module; be it accessing with CAS/RAS, switching memory banks, or starting on a new thread, electricity is going places it shouldn't go. When that happens, the problem is bound to compound itself. You have one error, you will have more.
