Size:
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.

Reserved
DRAM Throttle Lock (DTLOCK):
This bit secures the DRAM throttling control registers
DT*EW and DTC. Once a 1 is written to this bit, all of
these configuration register bits become read-only.
Throttle Test Mode Enable (TTME):
This bit is used to shorten the time window over which
the filter averages.
Reserved
DRAM Bandwidth Based Throttling Enable
(DBBTE):
0: Bandwidth Threshold (WAB) is not used for throttling.
1: Bandwidth Threshold (WAB) is used for throttling. If
both Bandwidth based and thermal sensor based
throttling modes are on and the thermal sensor trips,
weighted average WAT is used for throttling.
DRAM Thermal Sensor Trip Enable (DTSTE):
0: Memory controller throttling is not initiated when the
thermal sensor trips.
1: Memory controller throttling is initiated when the
thermal sensor trips and the Filter output is equal to or
exceeds thermal threshold WAT.
