    Nope.

    Example:

    A 333FSB CPU with a 10* multi, stock 3333MHZ.

    Setting 400*10 for 4GHz may require 1.35V, but 500*8 for 4ghz may need 1.3625V.

    Give it a bit more Vcore if you think it needs it, dialling some more in and testing will see if it helps.

    Anyways, low Vcore is over rated. Got a E7400 delivered today, and it's currently running @3.8GHz, 4 hours stable so far, with 1.392V in CPU-Z, 1.41875V in the BIOS with LLC, and it's ice cool at 60c.

    That's what I thought, which still leaves me wondering about how some people can hit 500x9 or higher with my chip but do it at substantially lower vCores than I can. I mean I had one brief success at 1.4vCore whereas I have read posts from other users that state that they had success at 1.36vCore. I understand that no 2 chips are perfectly identical, but that seems to be a big difference to me. Or are they lucky to have booted, BUT ARE not running stable?

    Anyway, I have reverted back to 333x9 for the time being. I read some stuff yesterday about electromigration and decided that I don't have the $$ to replace my CPU at this present time... haha.

    Are you using LLC (Load Line Calibration)? That could explain why you see people running lower voltages than you.

    No, I am not, I read somewhere that you shouldn't use it when overclocking a 45nm chip. Then I asked you and Lsdmeasap about it and don't remember the answer, haha. Should I be?

    And if I turn it on, will I then have to re-tweak my existing profiles to accomodate it?

    IMO, don't use LLC until you can't make just over 1.3625V stable. If that's the case, try LLC and exactly 1.3625V to see if you can progress. DO use it if you have to to get the clock speed you want. It won't break a 45nm chip.

    I do get irritated however when people use it so they can claim stupidly low voltages at modest to good overclocks. Something like "I have an E8600, E0 at 1.230V, LLC on running 3.7GHz". that's all well and good, but you're not actually running a straight 1.230V. LLC disables the safety measures that ensure your Vcore never goes above what you set in the BIOS. I wouldn't be surprised if at times, with LLC on that persons Vcore doesn't spike to 1.3V or more fairly regularly.

    Use it if you need it, but don't use it unless you have to. Using LLC is running your CPU out of spec, just as much as exceeding 1.3625V is. Know what LLC does, decide if you want to use it, and do so carefully. Just as carefully as you'd treat going over spec on anything else.

    Obey the one and only rule without question when you overclock.... don't cause a fire. Fires are hot and burny... not good. Other than that, have limits but be flexable with those limits. Electron migration is interesting but don't let it stop you overclocking. I bet my bottom dollar you won't have the same machine in 3 years time. It will outlive its usefulness long before you kill it.

    Good luck. I tried briefly to get a 500 FSB on the E7400. No luck regardless of multiplier.

    That will be a sweet overclock if stable.

    Regardless of stability would you be able to post a screen of SuperPI run to 1M decimal places? I'm curious as to how fast it'll calculate given the monster FSB. My guess is about 10.5-11.5 seconds. Possibly faster, never run 500 FSB before.

    Psycho,

    when I had it at 4.5GHz, very briefly last week, I got one run of SuperPi 1M in before it crashed.... 10.5s

    After the Prime is done (in 9 more hours) I will do it and post screens @ 4.25 GHz.

    A guy I met at another forum has the same set up as me (EP45-UD3P / E8400) and he has managed 4.5, 4.6, and 4.8GHz runs, albeit he knows they aren't stable and has no desire to stress them... only doing it to do Pi benches, not for 24/7 set ups. He said that he raised his vCore to 1.47 to hit 4.8GHz... I don't know if that is at a 9 multi or lower though, he didn't say. However, i think he said that his 4.6 build was.
