This will give you a better OC, depending on how much your voltage drops..
Mine will drop from 1.325~ to 1.26 under very high loads, less so with less taxing games.
In a specific case, NS2 i have voltages dropping down to 1.25~ and it stays around there, max GPU clocks at that voltage is 1254~, with a constant 1.325 with LLC at 0% max stable clock rises to 1346.
So yes, enabling llc to default will lower overclock.
ii) for me i have to considerably lower core clock in games that LLC causes crashing.. You will know when its LLC. Find your stable clock with voltage of 1.25-1.3 with LLC at default, then set LLC to 0%.. Try games and other benches and see if you are unstable.
i) That is what I knew about 0% LLC as well. But the contradiction is my experience when after doing volt mod, setting LLC to 0% and updating driver to 332.21, my previously stable OC of 1202/1752 @1.212v in BF4 crashed.
But can't the voltage also go up by a certain amount when LLC is enabled? Is it possible that (before disabling LLC) when I set the voltage to 1.212v, it was going up by 0.025v to allow those speeds to be stable? (I'm thinking no, since the volt mod wasn't enabled and the limit on voltage was 1.212v).
And why would voltage drop by that much, especially since LLC is disabled?
ii) Isn't the whole purpose of disabling LLC to increase overclock? So isn't it kind of deleterious that it is forcing you to lower your core clock?
That is exactly what I did. BF4 ran fine at 1202/1752 @1.212v with no volt mod, default LLC settings and 331.93 BETA drivers. Then I did the volt mod, disabled LLC and updated to 332.21 WHQL and the same speeds at the same voltage crashed. What do you suggest I do now?
I apologize for the long post.
And btw, kudos on that overclock. I wish I could run that kind of speeds on my Titan.
