I have just oc'ed my first comp. But I don't know why I can't get over 118 bus. It is stable at 118 then somewhat stable at 119 ( it rebooted after about 10min into a stability test), but it will not even post at 120! I'm begining to think it is the shuttle board and the via chipset, but I'm not sure. My temps are 29 idle and 47 load. 2 512MB ram chips with hsf, and hsf on chipset,and geforce gpu. 4 80mm case fans 2 in 2 out, but I don't think that heat is my problem. The case temp at load is 37. The vcore says 1.69, although I have never made any adjustments on it (not available in the bios). Anyone have any ideas?
