Dear: Mitch,
>>
>> After further analysis, we just found out that when temp increase
>> to 100 degree, ( PROCHOTB# will assert from high to low ) That tell
>> us the TM3 function have been active, It will drop to 95 degree,
>> and the PROCHOTB# will back to high,
>> The Vcore still remain 0.796 during TM3 active, after confirm with
>> VIA , it is because the CPU LFM Voltage was 0.796 , so it will
>> never change during speedstep “ Enhanced PowerSaver” or TM3,
>> We still have CPU C status function can reduce the Vcore voltage ,
>> Did you wish to trun on CPU C status for further testing ?
>>
>> Sincerely yours
>> Gary Chiang
