Hm, no fun so far, because first AVAST did not let me start the LLC.exe at all and now i managed to get it in the Autostart folder but it won´t execute by it self when the computer is starting....
What am I missing...?

Not sure but you are better off overshooting voltage with the mod to compensate for LLc rather than disabling LLC due to issues LLC has started causing recently thanks to ninjanupdates from nvidia.

Yeah, that's the only way I can avoid shut downs. I use 1350mV to get an effective 1320-1330mV or so under load...
post #23194 of 28136
Oh okay, that´s a good workaround.
Will do it that way.
Thank you guys.

I just set the LLC.exe on my Taskbar and fine.
Works for me smile.gif

Hey Cpt "Clueless" (its german for "Ahnungslos" right?) you don't look clueless to me! tongue.gif
Dont forget to reset LLC if you are having weird shutdowns or black screens and freezes! wink.gif

Hey, how do you know, that i had a black screen with a nice freeze?!?
Uhm, why, how and why should i reset the LLC?

And yes, I am "Ahnungslos", because I just mimic everything that seems interesting to me, without knowing what I am doing there... biggrin.gif

I have a sixth sense for these things! tongue.gif
It introduces those freezes due to some cards power section (VRM's) cannot withstand the sustained current that is set when the LLC is set to 100% (i know is says 0% but really is 100%) tongue.gif

Read my article of opinion about it:

"IMO, The way LLC works makes some cards crash because the VRM's cannot cope with the sustained power without variation as its harder for them to sustain it! the overshoot with LLC at 100% (ON technologies, makers of the NCP4206/8 voltage controller labeled it at 0% but its really 100%) is actually higher than with LLC at default!
Voltage is not to worry about but the amperage drawn by the voltage increase, you can limit the TDP at a "safe" level (depends on the card) with the AB slider (thus limiting the amperage), make the necessary calculations with my formula to find the maximum drawn wattage:

aW x b% = cW (a= bios base TDP, b= OSD TDP, c= aproximate power draw)

Then convert it to Amps:

The current I in amps (A) is equal to the power P in watts (W), divided by the voltage V in volts (V):

I(A) = P(W) / V(V)

Knowing that: 6 Phase VRM´s (CORE) 60A each = 360A

The only voltage you can control is the core, so:

DC-DC = I(A) × V(V) = P(W) =» 360A x 1.6v = 576W Theoretical MAX Wattage for the core

Lets think "safe" but at the same time not restraining the chip: 360A x 80% = 288A

Amps to Watts:

The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V):
I(A) × V(V) = P(W)

288A x 1,20V = 245.6W
288A x 1.30V = 374.4W
288A x 1.40V = 403.2W

You can go lower depending on the cards needs! As every card is different in power draw you have to fiddle with it to find your best "safe" limit! thumb.gif"


So, if enabling 100% LLC is giving you freezes, just delete the LLC.exe inside the startup folder and do a complete system shutdown (reboot wont work as the voltage controller will maintain its logic state and LLC will still be enabled) when you get back to windows after the shutdown the LLC level will be back default 56%! thumb.gif

The conceptual problem with LLC is that it is based on a sampled input, rather than a predictable, continuous function. Also, chips are designed with vdroop in mind.

What this means is that LLC will cause voltage spikes, both high and low. When load goes up, it will spike low. When load disappears it will spike high. Apart from the obvious likely repercussions (high spike burnout), noisy voltages tend to destabilise things, particularly if the LLC spikes interfere constructively with the ripple that inevitably always leaks in from the input power frequency.

In real, practical terms this means the benefits won't be universal (and probably not consistent in many cases).

True! chips are designed to "work better" with Vdroop, the 56% LLC default in GK110 is enough to prevent big voltage fluctuations and at the same time does not overshoot voltage too high, actually LLC at 100% will hamper OC´s in the majority of cases!
My advice is always to keep it default! smile.gif
