Loadline Calibration????

1128 Views 21 Replies 9 Participants Last post by  da tick 07
Okay so i just finished with my friends build and i raised the vcore of the core i5 750 to 1.20 and disabled load line calibration. His motherboard is the asus p7p55D deluxe and after we left hte bios we ran OCCT and his voltage was 1.29 at idle then during OCCT it dropped to 1.14 to 1.152. How do i stop it from dropping that much?

wait it should be enabled? i thought it was another thing for voltage droop and it should be disabled?

That would be C1E and SpeedStep.

ohh yeah i disabled though. what exactly is loadline calibration?

Either way during hte stress test it passed 1 hour at 1.14v when it dropped

its like a vdroop mod built into the board. It decreases the amount of voltage is dropped upon load.

ohh okay sweet thanks ill enable it for him when he comes over again next week with the dark night he ordered today so we can start overclocking.

That's nice
.

It's a feature to reduce vDorop as said before
. Some say it's dangerous due to an Anandtech article, but I've been using it for 9 months now w/ out problems

We actually have a forum member who is doing tests to see if in fact it is dangerous to use LLC on 45nm chips.

hmmm... how would it be dangerous?

Supposedly, LLC causes spikes in the voltage going to the CPU.

Instead of the voltage decreasing under load, it actually increases during load.

Over what the set limit/loadline is which is a spike. These spikes sometimes go wayyyy over and causes short but sometimes dangerous overloads to the CPU.

Vdroop is a design feature. LLC disables it, causing higher voltage spikes when the processor utilization drops. I would rather just raise the voltage higher and deal with the vdroop than disable a safety feature.

thats what i was kind of thinking

I tried it once and it actually dropped worse than with it disabled and failed a stress test.

it can get confusing between vdroop and vdrop but i use LLC without any problems. actually i couldnt get my cpu stable at 1.45 volts without it and with it im under 1.425 volts

What did you use to measure the voltage, and how do you know it's accurate? You may be surprised if you take a reading directly from the motherboard with a voltmeter.
