True that...almost 5 years for the Anand article. Can you explain to me the difference then? I currently understand LLC like this:
It stops vDroop and on new boards can be activated at different levels. The result is that the cpu reaches a higher voltage under load which is good for stability. It has two side effects. One is that voltage spikes will rise above your set voltage (simply because this is what Vdroop prevents). This isn't so bad as long as you realize that they would not go above what your voltage had been set to had you not gone with LLC. The second is that the faster voltage regulation and higher volts put out cause more strain on the power delivery components creating more heat. The nice thing about it is that you can run your cpu idle
voltage lower because it won't fall as low under load.
So the question is whether the you want lower idle voltages or if the extra load on the power supplying components is worse (higher temp). If you are at load quit often like me (BOINC) then probably it is not worth it. If you're not then it probably is good although then you might want to consider using offset voltage instead of manual settings.
Feel free to correct me...this is only from some online reading over the last few days.
Some questions I still have are..
how is it that a really high LLC can cause you to increase your voltage above your set point? If I am right (which might not be the case
), then cancelling out vDroop should only at most bring you up to your set voltage at load (no vdroop), but I have had a higher load voltage than set voltage with high enough vDroop.
Can LLC cause a voltage spike beyond what would have been set without it?
