When you enable LLC, the voltage stays steady regardless of what you do --I think that's the whole point of LLC. If you don't have LLC enabled, the voltage can shift.

When I open up CPU-Z on startup, the initial load voltage appears --I think that's the maximum it will go up to. However, after the system is on a bit, the CPU voltage drops some, even if Prime95 is on and maxing all four cores.

I have taken VCore past what it would have been had LLC would have been if I'd stayed with startup VID as my VCore (I'm now at 1.225 in BIOS). It is stable so far. Despite that, temperatures seem to be a little lower (say 2C) than if I had LLC on and the lower startup voltage.

One other note: CPU-Z reports a lower voltage than what is set in BIOS for VCore. I may be set at 1.225v, but it is reporting 1.136 right now (the highest I've had is 1.168v at startup). When using LLC on stock VID (1.1875v) CPU-Z reported 1.152v.
Then I want to ask it another way:

To answer my question (and to reveal some useful information to yourself), start by reverting back to your old settings prior to disabling LLC. Run the Small FFTs test in Prime95 for about 30-60 seconds, and then make note of the steady voltage reported by CPU-Z.

After that, go to the newer settings where LLC is disabled. Run the Small FFTs test again for about 30-60 seconds and make note of the voltage that CPU-Z reports most of the time.

Now: were those 2 voltages the same?

I mean, I understand how LLC works, what it does, and what its purpose is. I'm just wondering what I asked above.

As for the BIOS reporting a lower voltage with LLC disabled: this is normal, and it's behaving the way Intel intended it to. The idle voltage is the result of vDrop, and the load voltage is the result of vDroop.


Note: the Small FFTs test will have the heaviest vDroop in Prime95. But it's possible to have even more vDroop with the Linpack test.

i used to tune with llc disabled all the time.. it has a massive inpact with temp @ linpack
for instance

id run 1.48750 llc disabled @ linx load vcore was 1.328 temps 68 - 71c
id run 1.38750 llc enabled @ linx load vcore was 1.328v temps 76- 80c

but then again when you are pushing past 4.3 you would need 1.5v+ without llc (depending on the vid) just my 2 cents

How safe is letting the idle voltage be that high tho. I look at it this way llc keeps idle and load voltages low but with it off your idle can be very high and that could kill the cpu over time to.

Having a SERIOUS issue guys

My computer refuses to go past POST.
I've unplugged all USB devices and still won't go. Reset CMOS and it won't go. I've changed SATA cables and it still doesn't go.
What is going on?!
I want my computer back

Unplug the PSU then press and hold the power button down for a minimum of 30 seconds. Now plug in the PSU and try it. If it still doesn't boot it's time to start checking the hardware. Remove the ram and try it with only one stick. You might need to try each one individually to see if either works. If that doesn't help remove the hard drives and optical drives and see if it will post to the bios. If not, try the good old DFI Long Bios Clear. You have to do each step exactly as stated and if you miss one you need to start over from step 1. I know that you stated that you already cleared the CMOS, but sometimes system like these that have a complicated bios full of overclocking settings get confused and it takes more than a normal clear cmos to reset them and get them back on track. It worked for a couple of others in this thread.
  1. Remove power from the rig by disconnecting the power cord from the wall outlet.
  2. Make sure the PC Speaker is plugged in.
  3. Remove the Battery.
  4. Move the CMOS jumper to CLEAR.
  5. Press the Start Button on the case or motherboard to drain the capacitors.
  6. You may leave the board in this condition for as long as it takes to clear the CMOS. If a short 30 second clear or a 15 minute clear doesn't work, try an 8 hour clear then a 24 hour clear.
  7. Plug in a PS2 Keyboard.
  8. Put one stick of RAM in the slot closest to the cpu.
  9. Replace the Battery.
  10. Move the CMOS jumper to Normal.
  11. Press and hold the Insert Key on the Keyboard.
  12. Apply power to the rig by plugging the power cord into the wall outlet.
  13. Press the Start Button to power the rig up while holding down the insert key.
  14. When you hear the BEEP, release the Insert Key and press the Delete Key on the Keyboard.
  15. Once you enter the BIOS set the DATE and TIME then Load Optimized Defaults.
  16. Save and Exit.
  17. Enter the BIOS again and set it up the way you want for your particular rig.
