Investigating a failure to read DIMM SPD data on Intel Xeon Scalable platforms

Memory DIMMs have a small flash memory chip (EEPROM) on them, containing an important descriptor table called the Serial Presence Detect (SPD). This data tells the system the size, speed, timings, operating voltage, manufacturer, part number, overclocking profiles, and all sorts of other information about each DIMM. The SPD chip is accessed using the SMBus… Read More Investigating a failure to read DIMM SPD data on Intel Xeon Scalable platforms
