Yes, if you're going for a nice big OC, set that thing to +20%.

It's basically one of those "I rather have it and not need it, than need it and not have it".

I would keep it at +20% if I were you.

In theory this feature only works for multi card set ups so it probably wouldn't help in that situation...saying that it wouldn't cause any harm to disable it to see if it helps as you can always enable it again afterwards by reversing the process if you didn't notice an improvement.

Not even battlefield 3.. Crysis 1 or 2 can detect the minimal of bad overclocks that only need a little bump on the vcore or a few clocks down to get fixed..
Reduce temps? Drop the vcore and clocks... 95c your vram probably would be like 20c higher "yikes"...

I will drop those temps..
Look at my crysis 2 gains and decide best case scenario... Specially you that are on CF...
I wouild sacrifice a few mhz for better temps thats for sure...

95C is not safe. I suggest you look at more intake case fans to blow air onto the cards and outlet case fans to exhaust heat out of the cabinet. If you don't have any more fan provisions then look to lower down the clocks to 1100 Mhz and try to get the temps to below 85C.. you don't want to risk your cards in the long term. so play safe. thumb.gif
also make sure your cables are tied up and managed in such a way that they don't obstruct cool intake air flow to the graphics cards..

Welcome to my situation. Can't do more than 1220MHz with these Lightnings because temps get too high (can really only do one loop of Heaven at that clock before temps get to 90C). Only solution I've found is going full water...
