For what you deem it worth: There is no need to re-enable logging.  The logging is reset every time the system is rebooted, and once the number of correctable errors reaches a certain threshold, whether that takes seconds or weeks, it disables the logging and stops counting for that boot, suggesting the DIMM be replaced.
PowerEdge 2800, Windows SBS 2003 Open Manage identified a bad memory module and after multiple "ECC Error Correction Detected" warnings it coughed up a "correctable memory error logging disabled" error. The bad memory module was replace and the system restarted and the red X next to memory in Open manage is gone. I am wondering if I need to do anything to enable the error logging again or if the system automatically starts it up each time the system is booted so only issues an alert when it has been disabled.  There is noting in the help file about enabling memory error logging that I could find. Thank you.
