3930k+Sabertoth Vcore concerns.

hey guys,

I have a daily OC of 4.4ghz@1.35V (which i know alot of you will say is high) 100% stable never misses a trick. Under full load i do get a touch of voltage drop but still stays stable and the package maintains reasonable temps.

But now I've found myself wanting to find the true limitations of my current setup. I turned up the multiplier a touch to 46 changing the Vcore slightly to 1.38V. Booted fine. Went to start Prime....Crash.

So went back into the bios and boosted a few things to hopefully gain stability. Which it did. But i noticed something which has me a little concerned as seen in the first pic i bumped a few things ups.

But as you'll see the Vcore exceeds the setting that i have set.

This is what we are seeing under load initially (after 2min).

Underload after 6min when i decided to stop the test due to the obvious.

Obviously my initial concern is the fact that the Vcore decides to well exceed what i have set manually.

Is anyone able to explain why this could be happening? or point me in the direction of where i can find out? (if you require more info let me know)

I realize it may just be the Silicon lottery but.....

Is there any other possible reason as to why its requiring such a huge voltage jump to get such a small increase? And is there a setting i can tweak to bring my Vcore back down yet keep stability?

any help would be appreciated, extremely curious to see what the max stable is without killing my CPU..... I dont intend on using above 4.4ghz at all its just a one off :-)
 
What do you have your load line calibration set to? That could be the reason the vcore is showing higher then what you have set in the bios.

For 4.6ghz I am running 1.35v in bios with llc set to high and in cpuz it runs at 1.336v. You should be able to get similar but it would depend on your chip.

1.4v should be your limit for 24/7 use and 1.4+ is very high volts.
