Is PLL Overvoltage needed for 3770k @ 4.5GHz?

post #1 of 3
Thread Starter 
What exactly is PLL overvoltage? I have it enabled and I have my CPU PLL at 1.7v. I have my vcore at 1.25V and I fail prime95 at 8hrs and 30mins. Its weird because the other day when I had PLL overvoltage off, CPU PLL at 1.7V, and vcore at 1.26 I failed prime quicker at 3hrs instead of 8hrs. What do you guys think I should change to get stable?

Lower PLL voltage to 1.5v, and simply use your voltage offset and set it to around 1.27v. The offset will prevent your CPU from hitting auto setting voltages, and 1.27v will only be needed at 100% full load (which almost never happens in the real world), so you should still stay at decent temps.

What CPU cooler od you have?

Do I leave PLL overvoltage on or off?
