I5 3570K Cpu-pll Info Needed

post #1 of 4
Thread Starter 
I am tweaking the overclock of my I5 3670k and wonder how low can the cpu-pll be lowered. Is there anything wrong with lowering it, then testing with prime and if ok keep lowering it till prime makes the pc crash then upping pll till its stable. I am new to overclocking and wonder, what does cpu-pll volts regulate.

On Ivy's the cpu pll can be lowered to around 1.55-1.7 safely. I run mine at 1.7 for 4.5ghz overclock. Also for most overclcoks at 4.5+ you need to also enable internal pll voltage for increased stability.

I've been able to run 1.7v for pll all the way to 4.9GHz, Anything lower and my system will crash like crazy. I still have pll over voltage disabled even at 4.9GHz. Every cpu and MB will need different settings, So you really have to try for yourself and see what works thumb.gif

For what it's worth, I usually run mine at 1.6. For some reason I had reset it to stock (auto) and started experiencing odd problems, anything stressful would simply turn-off my computer and restart it (like a complete power-loss). No BSOD or errors anywhere.

Couldn't figure it out until I saw PLL was on auto, once I put it back down to 1.6 it hasn't happened again.
