 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
