Programmable Event weights are input into the averaging filter. Each Event weight is an
normalized 8 bit value that the BIOS must program. The BIOS must account for burst
length and 1N/2N rule considerations. It is also possible for BIOS to take into account
loading variations of memory caused as a function of memory types and population of
ranks.

Memory Controller Throttle Lock (GTLOCK):
This bit secures the IMC throttling control registers
C0GTEW and C0GTC. This bit defaults to 0. Once a 1 is
written to this bit, all of the configuration register bits
are read-only.

Throttle Test Mode Enable (TTME):
This bit is used to shorten the time window over which
the filter makes its calculations.

Memory Controller Bandwidth Based Throttling
Enable (GBBTE):

throttling. If both Bandwidth based and thermal sensor
based throttling modes are on and the thermal sensor
trips, weighted average - Thermal (WAT) is used for
throttling.
Memory Controller Thermal Sensor Trip Enable
(GTSTE):
the IMC thermal sensor trips.
Memory Controller thermal sensor trips. WAT is used to
control the bandwidth. Thermal sensor trip overrides
counter based throttling.
