Never used LLC before, can you explain it?

post #1 of 5
Thread Starter 
So I've always overclocked without it, and I know my board came with it but I thought it was just something automatic, just saw I can actually use these settings. I'm on my 965BE until I get something better in a month or so and 4.0ghz is all I can squeeze out of this thing and 4.1-4.2 is possible but not with the amount of voltages I need to get it.

So what is LLC, what do the different levels mean and how does it benefit overclocking, and in what scenerio would I use it?

It basically allows you to overclock higher or lower (depending on board manufacturer). It automatically downvolts itself based on the level you have it set to and what voltage you set manually. Used as a throttle.

Other members will have better answers, but that's laments terms. Hope that helps redface.gif

Intel added a special circuit to cause something called vdroop (different from vdrop). It slightly lowers voltage when heavy loads are on the CPU to help decrease temps. When overclocking, the default vdroop is typically too powerful and undervolts the CPU too much, causing a crash. Increasing LLC (load line calibration) decreases the effect of vdroop. Generally you want to increase LLC until you a little vdroop. Some people set it so there's almost none. Usually vrise is a bad thing, it'll unnecessarily raise temps. If it's set too high you'll get a vrise. Also when it comes off the load that rise will go back down, which could potentially cause a crash.
