Memory Combined Rd/Wr Thermal Weight Hot-2
Threshold (MemCRWTWHotM2Th)
The Hot-2 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-2 thermal weight threshold is reached or not.
This threshold level should be set lower than the Hot to
Hot-1 threshold, but higher than the Hot-3 to Hot-7
threshold levels. Since there are 8 NearHot-to-Hot levels
defined, the minimum that this field should be set to is
0006h, 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 FFFDh, 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-3
Threshold (MemCRWTWHotM3Th)
The Hot-3 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-3 thermal weight threshold is reached or not.
This threshold level should be set lower than the Hot to
Hot-2 threshold, but higher than the Hot-4 to Hot-7
threshold levels. Since there are 8 NearHot-to-Hot levels
defined, the minimum that this field should be set to is
0005h, 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 FFFCh, 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.
