Memory Combined Rd/Wr Thermal Weight Hot-4
Threshold (MemCRWTWHotM4Th)
The Hot-4 thermal weight threshold used for memory
combined Rd/Wr thermal weight tracking. This 16-bit value
is compared to the MSB (i.e., [38:23]) of the thermal weight
counter value, to determine whether the HOT-4 thermal
weight threshold is reached or not.
This threshold level should be set lower than the Hot to Hot-
3 threshold, but higher than the Hot-5 to Hot-7 threshold
levels. Since there are 8 NearHot-to-Hot levels defined, the
minimum that this field should be set to is 0004h, to avoid
overlapping levels if all 8 NearHot-to-Hot thresholds are to
be used. Similarly, the maximum that this field can be set to
is FFFBh, if all 8 NearHot-to-Hot thresholds are to be used.
Overlapping levels can certainly be set when less than 8
thresholds are to be used. To use 1 threshold setting only,
effectively disabling adaptive throttling, all 8 thresholds can
be set to the same value.
Memory Combined Rd/Wr Thermal Weight Hot-5
Threshold (MemCRWTWHotM5Th)
The Hot-5 thermal weight threshold used for memory
combined Rd/wr thermal weight tracking. This 16-bit value is
compared to the MSB (i.e., [38:23]) of the thermal weight
counter value, to determine whether the HOT-5 thermal
weight threshold is reached or not.
This threshold level should be set lower than the Hot to Hot-
4 threshold, but higher than the Hot-6 to Hot-7 threshold
levels. Since there are 8 NearHot-to-Hot levels defined, the
minimum that this field should be set to is 0003h, to avoid
overlapping levels if all 8 NearHot-to-Hot thresholds are to
be used. Similarly, the maximum that this field can be set to
is FFFAh, if all 8 NearHot-to-Hot thresholds are to be used.
Overlapping levels can certainly be set when less than 8
thresholds are to be used. To use 1 threshold setting only,
effectively disabling adaptive throttling, all 8 thresholds can
be set to the same value.
