1.6v limit, dont they realize 4 way boards need more volts than that.... sheesh......

I'll take a wild guess that lately most system component manufacturers (i.e., MB's/GPU's/CPU's) are putting more "restrictions" in/on their products to keep us Crazy OC'ers from Melting them!

Very likely, but shows how well they know us REAL clockers... we won't melt it, we are getting it colder!

Restrictions? That board will do like 1.8V

A Little Help Please if you will, johnksss
 
Can You tell me what I need to do, I've tried everything I thought would work to get past 1.6v Vcore in the UEFI BIOS Overclocking with a 3960X CPU.

First page mid way down you will see a setting called extreme OV. Set that to enabled.
That will unlocked 1.7V. And in the os you can get another .640V using AIS 3, but you would more than likely need ln2 for that. You should be able to use up to like 1.65V or so.

Thanks for the Info, I had already enabled the extreme OV, But that still didn't allow over 1.6v without boot errors (i.e., CPU voltage too high or Overclocking Failed press F1 to reboot).
Also there were times trying to get past 1.6v that when it actually Did try booting up, 3/4 of the way into the Windows 8.1 Desktop, the Whole System would just Completely Shut Down, which made me think it possibly had something to do with the VRM Protection enabled setting in the BIOS, But disabling that setting made no difference and since I have Chilled Water Cooling on the MB I didn't think it was an Overheating problem anyway.
 
This 3960X was loaned to me by doorules that he had running at 5.4GHz at 1.64v on his ASUS RIVE on Chilled Water Cooling, But on this RIV BE I haven't found out why there is this vcore limit yet.
It is Not a PSU issue because I swapped out my Thermaltake Toughpower 1200W with a Third New Rosewill Hercules 1600W/110A single-rail PSU dedicated once again only to the MB with exactly the same results.
 
As you have stated, I Should be able to get up to at least 1.65v or so with this MB, But I still haven't come up with any reason other than possibly hitting the OC ceiling for this 3960X even with temps of -40C at the SS Evap Head and a reported temp (ASUS OC Panel) on the CPU of -10C to -12C while under Benching Loads.
 
I have PM'd raja at the ASUS Forums who said it Could be the phase unit is falling over when the CPU pulls current and the temps are soaring and that 1.60V is a lot for a single stage phase unit when the OS loads and the processor goes into full load.
 
Maybe there is some Merit in that explanation, But I have even tried setting the vcore past 1.6v at the Default 3.3GHz CPU speed where you would think the temps are out of the equation, But No Such Luck Again.........Still can't go above 1.6v without having the same problems.
 
 

Did you turn off the cpu voltage monitor?

Did you turn off the cpu voltage monitor?
 

Yes, And although that did allow me to raise the Vcore at the Defauilt CPU 3.3GHz to as High as 1.8v, I still could not get higher than 1.6v when trying to go over 5.4GHz without getting the same error messages as before.
 
However, I happen to notice a Program similar to EVGA E-LEET that was in my RIV BE software package called ASUS TurboV Core that allows multiplier and voltage adjustments while in the Windows 8.1 Desktop and found I could go past the BIOS setting of 1.6v to 1.8v.
 
While using this software I have reached 5.425GHz at 1.648v as shown in the Pics, CPU-Z and HWMonitor,, But I believe I'm at the Limit that my SS Phase Change will allow this 3960X to OC, So Yes, I have solved the Vcore Problem, But unfortunately any further Vcore Increase will not help OC any higher without errors.
 

 

 
 

That is AI3
I thought this is what you were using. This is an Asus board not an EVGA board.
And once you hit you last wall. You will in fact need to run LN2. The Chip has like a temp stage. Best way to describe it. And if you are not below it your chip will not clock any higher. Example. That temp could be -80C.
