i7 860 safe to run at 1.4vcore and 1.4 vtt 24/7?

post #1 of 12
Thread Starter 
Is this safe? I think this is the only way I'll get 4.2ghz unless there's some stability options I can set and it will help me lower voltages?

It will be perfectly fine so long as you can keep the temps in check. Around under 80c core temp is what I would shoot for. I've seen people run up to 1.45v 24/7 for years without issue. Your VTT is also at perfectly acceptable levels. I try and stay under 1.45v for that one.

Damn, got an error at 4.2 with 1.4 for both, is it too risky to keep trying to raise the clock? or should I lower my goal to a more realistic 4ghz? redface.gif

if you have a good cooler, like an H80 or something, push it as far as 1.42 and no more on the VCore, but in this case, 4.2 @ 1.4V pretty much is the makings of an average chip, at 1.42V is should be rock stable @ 4GHz, but i would try raising CPU PLL

How much should I raise cpu ppl?
post #6 of 12
You can try raising the QPI PLL VCore or IOH Vcore as they tend to help stabilise a higher BCLK.

bump it up by say... 0.05V more than the current voltage

I don't have anything on my mobo that says IOH v core and the only opi I see is qpi frequency I selected the lowest one.

I have cpu pwm frequency which says lower for cooler mosfets higher for extreme overclock.


Edit - I have a noctua cooler don't know which one.

Ah ok, I'm not all that familiar with the board redface.gif I gained stability by dropping the CPU PLL down, but it just seems your chip might not have 4.2 in it. Is all the ram running at it's rated specs? Timings and voltage wise.
