CPU N/B Load Line Calibration?

post #1 of 7
Thread Starter 
Could turning on CPU N/B Load Line Calibration help with NB Overclocks? The reason why I'm asking is because I've been trying to attempt 3000mhz NB but so far 2800mhz is all I can get at 1.259volts_ 3000mhz is no go even if I boost voltages up to 1.5volts which is scary(Damn red numbers scares me lol)

What is up with CPU N/B Load Line Calibration option in my bios? Is it even necessary? Whats the purpose behind this setting? Just thought I would throw those few questions out there considering I can understand what CPU LLC does, but CPU N/B LLC thats an option I've never notice til today lol

higher...1.35 volts to 1.4volts would be good for the cpu-nb overclock of 3000ghz depending on your cooler and from cpu to cpu. uusually LLC will raise it by .03 to .05bvoltage for teh cpu-nb if anything.

Your BIOS may limit your CPU/NB overclock. That happened with my old CH III & 955 combo. Its funny, but if i remember correctly, an older BIOS let me OC my CPU/NB @ 3000, but but once i updated it, max was @ 28xx.

On CH IV & 955 combo I was able to hit 3000 for CPU/NB

Thank you for that information, I am gonna try a few older bios and see what it'll allow me to push_

Forget 3000MHz on NB. 2800MHz is pretty much max for 955(depending on board). Maybe a tad over. If the NB is unstable it would hurt your overclock. Get the overclock as high as you can and use 2800MHz or so. It depends on the board if you can get 3000. Hope you do and hope this helps.

first of all nice car xD
second some people have their CPU/NB @ 3GHz @ 1.39V
as for me i could only get my CPU/NB stable @ 1.50V @ 3GHz, and don't worry nothing will happen to your CPU/NB if you raise the voltage to 1.5V as long as the temps are down.
it all depend on your CPU chip
