An information handling system includes a memory controller with an error logger, and a DIMM coupled to the memory controller via a memory channel. The DIMM includes a non-volatile memory device mapped to include event blocks that store error information associated with memory events occurring the memory controller, the DIMM, and the memory channel. Each event block includes a flag field and a data field. The error logger receives an indication that a memory event has occurred, reads first flag information from a flag field of an event block, determines whether the event block is locked based upon the first flag information, and if the event block is not locked, then writes second flag information to the flag field and writes event information to a data field of the event block. The event information describes the memory event.

System and method for targeted efficient logging of memory failures

A dual in-line memory module (DIMM) thermal control system for intelligent DIMM thermal controls for maximum uptime may include a memory subsystem. The memory subsystem may include a first DIMM and a first serial presence detect (SPD) module associated with the first DIMM. The DIMM thermal control system may also include a baseboard management controller (BMC). The BMC may, when a first DIMM failure of the first DIMM may be detected, record a first failure event in a first failure events log of the first SPD module. The first failure event may comprise the first DIMM failure and associated first thermal telemetry data of the first DIMM. The BMC may also adjust DIMM thermal control settings to reduce temperature of the first DIMM based on the first failure events log including at least the first failure event.
