Things like LLC. Should i keep it on/off when trying to OC? Any other options in the bios that i should turn on/off when trying to OC a 2500k? He has an asrock p67 extreme 4 mobo.
LLC is Load Line Calibration. It basically prevents the voltage in the OS from going below what you set it to in the BIOS after Vdrop. Vdrop is an automatic difference between BIOS and OS. (Vdrop and Vdroop are different things)
Normally voltage won't go above what you set because of a safety feature called Vdroop. The higher the load, the more the voltage would "droop" or dip down. As such, you need a higher voltage in BIOS with LLC off than when on to compensate for the droop under load and maintain stability.
With LLC on, the voltage will actually go up slightly under load instead of drooping down.
It's personal preference really, but LLC can be useful if going for a really high OC so your voltage isn't sky high when idle. Despite what some may say, LLC has been shown to be pretty safe based on the multitude of OCers here on OCN. I leave it off though.Edited by Kaldari - 6/18/11 at 1:54am
