Claim 15:
16. A method comprising:
storing, via a basic input/output system (BIOS) of an information handling system, a plurality of derating values in a derating table of the BIOS, wherein each of the derating values corresponds to a respective decision feedback equalization tap value at a respective temperature;
during a power on self test of an information handling system:
performing, via a basic input/output system of the information handling system, a first training of a memory subsystem of the information handling system; and
storing tap values; and

during a runtime of the information handling system, if a temperature of the information handling system has changed by a predetermined amount, then
automatically updating the tap values based on derating values in a derating table, wherein each of the derating values corresponds to a respective tap value at a respective temperature.
