Disable or decrease VTT or PLL?

[grandpatzer]

46 x 100 = 4.6Ghz.
Vcore +180mv
CPU VTT 1.20v (Default 1.10v),
PLL Overvoltage Enabled.
CLL 75% (I think have nasty Vdroop).
My reported vcore is 1.392v - 1.424v during Linpack, mostly it is at 1.4v

Can I decrease or disable CPU VTT or PLL Overvoltage?

Trying Offset +160mv gave fast BSOD in Linpack

PLL voltage is to give you more stability on your OC, for sure leave that on.

VTT I dont have much experience with. But you can leave that default,, whatever the default is.

on what system ? eg. cpu, mb, bios version,psu

My Asrock/2550k likes a slight bump in what Asrock calls VTT. My 2550k needs PLL over voltage enabled at 5ghz or higher.

I only use offset vcore while overclocking and liitle LLC as I can get away with. I only disable C3/C6 because it causes random bsods under light loads using offset vcore at times.

The only fun these days with overclocking is finding stability

Your gonna have to play around and see what yours requires.

1.42v's under heavy load gets me 5ghz. I think LLC is on 50%
