Load Line Calibration and CPU Voltage???

~~scurvy~~ · Feb 3, 2009, 08:46 PM

Iam trying to OC my E6750 and I've noticed in CPU-Z that when my OC'd CPU is at idle its drawing 1.36V and when running Prime95 it goes down to 1.33v and stays there.

I read that its an example of Vdroop or whateva, but my concern is since this CPU is supposed to run at a max voltage of 1.35 (accordin to the box) will this idle voltage of 1.36 damage it in any way?

I also read that by enabling Load Line Calibration this Vdroop can be minimised, and thus my second question is if its OK to enable LLC and leave the CPU Voltage at 'Auto' instead of a specific number.

Thanks,
Scurv

Loadline Calibration can help with stabilizing Vcore but experimenting with it here I haven't achieved any drastic improvements overclocking with it on or off. On 1.36V shouldn't bother it google the min and max voltages for your CPU you might be surprised.

Vdroop isn't always a bad characteristic.

As for setting Vcore I would do so manually. I ran into a situation where "Auto" on a Gigabyte board forced the Vcore from 1.35V to 1.42V when this increase wasn't needed .... 1.35V ran the same O/C stable.
