Load-line Calibration

Zensou · 2009-11-27

AKA. Vdroop on/off. I read that it should be disabled when doing higher overclocks and enabled when doing lower overclocks, that it also can cause voltage spikes. On my motherboard it is called load-line calibration and I can choose to set it to enabled, disabled, or auto. Is it the same thing as "Vdroop on/off/auto" on other motherboards or are they different settings. For a 4ghz OC should I leave it at enabled, disabled, or auto? Example: During CPU load the voltage stays at 1.29v and during idle it stays at 1.29v, is this the effect of LLC? Even with LLC there is some undervolting in effect. In BIOS my voltage is set to 1.3125v, yet CPUZ always shows 1.29v. Is there a way to fix this or is it just a faulty motherboard? Thanks for reading.

If you can leave it disabled and be stable, then sure. At 4GHz you might have to enable it.

This is indeed LLC working.

This is normal voltage drop and nothing to worry about.

Don't use LLC.

LLC is perfectly fine to use. I use it all the way up to about 1.40 because Intel specs for safe voltage for my chip is 1.45 which is the highest LLC will spike. When doing very high benching I don't use it. But about 40 other people I know with this board use it and its fine.

One could also read that to mean "don't overclock."
