(SOLVED) CPU PLL voltage, decreasing safe even below 1.7v?

post #1 of 2
Thread Starter 
This question has been answered by my own testing, no need to reply, moderator may close this thread.

Hi,
After trying to use the 'search this forum' function three times, and ending up with a white page after 25-30 seconds, I thought I'd open a thread.

Basically it's one simple question, I have an i7 2600K and was wondering, when I start decreasing the CPU PLL voltage and stability testing, then vcore, is it safe to go below 1.7v on the CPU PLL voltage if the system is still stable?

I've heard decreasing the CPU PLL voltage helps gain a slightly lower vcore setting on some processors, more so on D2 stepping.

Even though the absolute minimum rating on the PLL voltage for all i7s (first and second gen) is ~1.7, I've never seen any evidence or heard any reports that lower PLL will damage anything.

Indeed, I've been running 1.3v CPU PLL (down from 1.8 stock) on my i7 970 for upwards of 6 months with no issues.
