Well i have found 907 to be the best one yet, i could not get stable on 400 fsb no matter what votages i used before, now i can get stable on 412x9 with only around 1.47 vcore and it just want to keep going, but my idle temps are around 35c and 52c after playing games, which means that the cores are at aroung 71-72 degress which im a bit worried about, i think im gonna lap the proccessor to see if it makes a difference
