Sin, can you do me a very urgent favor?

Find a safe and lower overclock so you won't damage your chip, and can you run a TEMP comparison with LLC1 and LLC2, with the "Target HARDWARE" (DMM) voltage for LLC2, to match the target hardware voltage for LLC1, and then compare the cpu temps at load? (Use Prime blend so the temps are easily maintained).

Good Example:
Use 4.5 ghz.
Set vcore to 1.45v bios, LLC1, and compare the temps after a few minutes of Prime small FFT (small FFT will get the temps higher faster than blend does).

Then, set the vcore to 1.30v (correction) bios LLC2, 4.5 ghz, and do the same thing.

If you're worried about chip damage, you can try 4.0 ghz LLC1 1.40v, and LLC2 1.25v (correction again).

*also, please use REALTEMP 3.67 while you're doing this, and check the power draw shown at the top right clickable tab*

^^^ THANK YOU SO MUCH, SIN !!!!!

The temps AND the power draw should be the same at load for both settings, if the DMM readout is the actual CPU voltage going into the chip, and if the chip is actually using that voltage.

I'm only asking, because I saw a very bizarre post:

I think i understand what you're saying, basiclly, lower the voltage and enable LLC level 2 so the load voltage gets what it needs, and idle droops since it doesn't require as much voltage, i did some testing and here is what iv'e learned about my rig.

It seems like it doesn't matter what Level LLC is on, as long as the BIOS has x.xx amount of voltage for that particular clock, it will stay as stable as it can/should be. For example:

5.0ghz
LLC Level 1 @ (BIOS-1.38v) Load: 1.35v - Crash
LLC Level 1 @ (BIOS-1.41v) Load: 1.38v - Crash
LLC Level 1 @ (BIOS-1.43v) Load: 1.408v - Crash
LLC Level 1 @ (BIOS-1.45v) Load: 1.41v - Passes many tests

On the other hand:
5.0ghz
LLC Level 2 @ (BIOS-1.38v) Load: 1.41v - Crash
LLC Level 2 @ (BIOS-1.41v) Load: 1.43v - Some errors and hangs, no crash
LLC Level 2 @ (BIOS-1.43v) Load: 1.45v - Some errors and hangs, no crash
LLC Level 2 @ (BIOS-1.45v) Load: 1.48v - Passed some tests but doesn't "feel" stable
LLC Level 2 @ (BIOS-1.48v) Load: 1.512v - Ran this for a long time with no errors or crashes.

So you can see the trend almost immediatly, It seems like it will crash if the "BIOS Votlage" is below a certain threshold, regaurdless of any other settings, and in some cases the LLC Level 2 is more unstable, I have 2 other settings for LLC, [Auto] which i haven't tried, and Standard, i skipped standard because it said "Intel's Standard Load line cal. and i'm going to be money it sucks for anything over 1.4v.

This is on a UD5. Which should have the same LLC as UD7.
