I already had a 4940mx official edition with liquid-cooling.And I can oc it to 4.3ghz stably.(+25mv) What i can do for oc my cpu more?I don't know how much the XTU safe current is. Because i always encounter current throttle if i oc more.I'm afraid my computer is damaged. Why 4930mx is a better choice when overclocking is used?And qs edition or official? I appreciate your reply.
