LLC (load line calibration). Is this setting okay?

[Ace McPlane]

So, I reduced the LLC with my asus maximus vii hero and i7 4790k to level 2 in order to reduce temps.

I'm not noticing any vdroop. The voltages aren't dropping under load and I'm maintaining my CPU frequency no problem.

Am I losing anything else by having a low LLC setting?

Will I maybe only notice vdroop under a light load instead of a heavy one?

I'd like to understand this better if anyone has any info.

Turning it down low makes a substantial difference in temps so unless there's some reason I should keep it on auto, I'm going to keep it this way.

With my 4770k llc didn't do anything at all vcore was solid even at 4.8ghz

so dint worry

if u don't need it at all that's perfect

You'd need a heavy load to see if you have vdroop.

 

LLC is to prevent vdroop while under load. The main issue would be random blue screens or just powering off.

 

I use LLC, but I have an R7 1700x at 3.9 and dual GPU. I would occasionally have vdroop when the GPU's ramp up from idle.

 

Otherwise, you'll be fine.

 

What is your cooling system?

LLC is only needed when you turn off C-states and dont want the CPU get too much voltage at idle. That's it

Cool, congrats on getting to 4.8.

Fractal Design s36. A 360 AIO.

 

Okay, since it passed a 24 hour AIDA64 test while maintaining it's frequency, I guess I'm fine to leave it off then.

LLC seems to add voltage under load. The lower the setting, the less voltage it adds. That's my experience. I'm not sure about the idle end of it.

When LLC isnt used and C-state is turned off, the voltage under load will be too low while being safe at idle. When it is used, it helps increase voltage under load without getting unsafe voltage at idle.

Well, I've got C-states, turbo and all of that turned on, but the LLC on a level 2.

My voltage actually doesn't decrease at all at idle right now.

I'm still getting used to this complicated bios and haven't found the setting to fix that yet so I guess I won't know if I have a problem until I do
