Level1 DRAM Temperature Threshold Value
Set the boundary separating Level1 Values and Level2 Values. When DRAM
Temperature is below or equal to this value, then Level1 Values get written. If above
but below Level2 Threshold Value, then Level2 Values get written. Temperature is
in degrees Celsius and at a measurement point close to the center of the DRAM.
Recommend Level1 Threshold value is 45.
Configuration options: [0] - [99]
Level2 DRAM Temperature Threshold Value
Set the boundary separating Level2 Values and Level3 Values. When DRAM
Temperature is below or equal to this value, then Level2 Values get written. If
above then Level3 Values get written. Temperature is in degrees Celsius and at a
measurement point close to the center of the DRAM. Recommend Level1 Threshold
value is 55.
Configuration options: [1] - [100]
