Yeah that is, ive seen plenty others needing to reach that 1.3v threshold, and the jump from 4.3ghz to 4.4ghz on mine was huge, i needed 1.34v for 4.4ghz.

Okay; try setting your offset to -0.020V and see what you get for idle and load Vcore.

Also check and see what your VCCIO and CPU PLL volts are, if your motherboard BIOS monitors them. You can also get something like CPUID HW Monitor or HWINFO64 to view them from the desktop.

Alright, I tihnk I lowered my CPU PLL from 1.800 to 1.750

Changing the offset from -0.045 to -0.020v causes the Vcore to go to 1.332 under load and 1.092v idle
PLL is at 1.75

Why...? I thought that you should focusing on getting Vcore where you'd like it first -- things like VCCIO and CPU PLL are later-on tweaks for when you're working on getting long term stability. I was just wondering where you had those at as an aside more than anything...

Wait -- did it drop in value on its own?

Try -0.025V next... that should put you below 1.3V at load and right around a volt for idle.

wouldnt that be higher then what i have now. I have it it -0.045v going to -0.020v brought me from 1.308 to 1.33 up so wouldnt -0.025 is still higher then my current voltqge

I put the pll back to normal. i just lowered it but ill put it back to auto

No, if you increase negative offset you're subtracting from Vcore -- it would shave off about 0.005V from both your minimum and maximum readings. That's the trick with negative offset: you're sliding the whole scale in the same direction, so your goal is to get the maximum Vcore where you want it without pushing the minimum down too low to keep the CPU stable at idle.

There's also positive offset, which more people here seem to be using, but I learned from the ROS Asus guide, where Raj used negative offset as an example, and I just stuck with it because it worked for me. There's apparently an argument to why positive is better than negative -- something about less stress on VRMs -- but negative been working flawlessly here otherwise, and I haven't been compelled to change the approach as I'm stable at 4.8 and I'd hate to wreck that and have to start all over. Mabye I will anyway at some point, once I understand the differences between the two better.

Here's the best and easiest to understand explanation anyone on Earth has ever given for it:

http://www.overclock.net/t/1353134/how-to-use-offset-voltage#post_19129654

That was why I suggested RealTemp, so you could also monitor VID.

This is why you start off with offset mode by having no actual offset -- you load the CPU to see what it runs Vcore to. If you feel it's too high, you offset in the opposite direction (-). I think that for positive offset you start at idle and add (+) for what you'll think you need at full load. I think. But the ultimate goal is to get Vcore to a value at load where it's enough to be stable but not too much that you're wasting energy and generating excessive heat, all the while having enough at idle to keep it stable there also.
