Hi everyone,
I have started overclocking my CPU, first ever, and found a bunch of reference materials.
The materials I'm referencing are:

Off the same thread above:

So if I understand correctly.
- Need to find the correct Vcore for the multiplier
- However before that Need to first find the correct LCC setting to minimize Vdroop (spikes) as much as possible.
- However need to know what your Vcore is under load - assuming it's the multiplier you wanted to find in the first place
- Then you need to increment your Vcore slightly until it's passing Prime85
- Then thereafter need to bring down the PLL voltage once becoming closer to stable.
So it all seems circular.
- How do I know what my multiplier will be when I'm trying to ramp up my Vcore based on it?
- Do I set my Vcore to 1.45, my PLL voltage to 1.7, the other parameters based on the P67 OC link from HR, and then keep increasing the multiplier until I see temp / stability concerns?
What I have done:
- Followed the guidelined in the first link for 4000MHz, and bios would flash and reboot again into window repair. So i kept raising my Vcore incrementally. After 4 increments, just tried 1.35v, and it finally booted.
- Tried 4500MHz, Ran Prime95, and although CPUZ confirmed that it hit 4500, it would soon step down the multiplier. I raised the Vcore to 1.4, and it still did the same?
- Reset all settings back to default, and tried the mobo presetting for 4400MHz, and everything ran fine. CPUZ was pegged to 4400 the whole time Prime95 was testing. Used the 4600 OC preset, also worked. Ran Prime95 running blend for 3 hours (short I know). My Vcore is 1.360 and my VID is 1.406 under load and my max temps have hit 73C after 1 hour into the test.
- Got help on other forums to set the max overclock (or something like that) from 150 to 250, when in manual OC settings, but still have the multi step down problem. Then read more about this Vdroop, PLL voltage to 1.7v, etc...
So I'm stuck.
If my manual setting does not peg the turbo to it's max, does that mean need to play with PLL? Vcore? Up/down? Something else?
Do I go to the 4800MHz presetting to see the voltages and then try to step it down from there?
Do i know my OC limits yet?
Frustrating point is that I'm traveling away this weekend, and wont be in front of the machine until Sunday night my time. So doing this from memory. :-/
Anyway appreciate some guideance on some sound steps to take...when to worry about PLL voltage, the VID to Vcore delta, etc.
