So currently i have my E4400 running at 333 x 9 at 1.250v but just wondering what happen if i raise the multiplier to 10 will I need more voltage to run it?
5 minutes is good enough for a quick test i suppose, But if you want to be absolutely sure, i'd run her at least 12 hours if not more. I do 24Hour stress tests personally. Should be cake if everything is stable.
Raising the multiplier isn't a get out of Jail free card, It ups the stress on the CPU, and may require equaling out. I'd try it anyway though.
