yes you need to get the pcr file for the kt133 or kt133 they are both the same then set register 52 to a value of EB that will set the chipset to allow the hlt instuction and you will see the temps go down I am running a duron 700 o/c to 945 105 x 9 on a msi pro 2 a board my temp before at idle were about 100 f now it drops down to the mid 80 s at idle and never goes above 111 f at full load
