This is weird, I had it at 140X15 and ran 3d mark, no crashes, played other games, no crashes.. But when i play Unrealtournment2k3 my system restarts. So I go back to default speeds and im fine again. Before i had this chip i had the 2100+ prcoessor with the fsb at 140 for 2 months without a single crash... Can anyone help me with this, would raising the voltage help me???? My temps are 32c normal, full load 37c ...
