Loadline Calibration (in BIOS), to enable, or diasble?

[LOUISSSSS]

options: Auto, Enable, Disable

i'm aware that this has something to do with vdroop and that it should be disabled for the 45nm CPU's, but what about for my 65nm Q6600 G0?

curently i have it on Auto with Bios vCore of 1.30v. in cpu-z i get an idle reading of 1.280v, and a load reading of 1.264v

AT ventured to look at the feature here

I would be leaving it disabled.

Usually Enable means the board will try to compensate the vDroop but the term can be different per BIOS. (In my DFI X48 it's the opposite.. )

I enable it (meaning less vDroop) against very knowledgeable folks' opinion. However I would make sure the board is well-built and has good quality components. There are trade-off's in that:

1. If you enable it, you have a chance of vCore overshoot beyond the allowable margin.
2. If you disable it, your CPU will need higher idle vCore to maintain the same overclock. (Like having to give 1.50V idle in order to maintain 1.40V under load)

Note that Intel's specs are never based on overclocking. So when overclocking comes into the equation, we need to consider situations like above. Personally, I'd rather have a solid 1.40V that might overshoot to 1.42V once in a blue moon than constant 1.50V that drops to 1.40V under load.

^^ good point, i have mine disbled right now for stability testing on my system. i'll look into some loadline calibration testing after i get my ramz stable

Loadline Calibration is the software equivalent of the pencil mod. It's designed to reduce vdroop which is why I linked to the vdroop topic so people can read more about it.
