Increasing voltage

[Mitrailleuse]

I want to overclock my GTX 660 even further,

so i want to ask if i should increase my voltage by 112 to achieve better clocks?

and how much time would it take from my GPU life?

Not much at all if you keep the whole card cool. 

 

Want more performance? You'll need an upgrade.  :(

 

 

 

If you're benching, use all of the volts B). Only if you feel comfortable though. Don't go pumping more voltage if you don't have the cooling headroom. You can change the thermal paste AND ramp up fan speeds of your card if temps are an issue. 

 

 

 

 

 

 

I guess you mean mV when you say 112. that's quite a jump in voltage.. baby steps.

I'm actually planning on getting another card and putting them in SLI,im a little bit short money wise.

i maxed the mV only because i want to see how much can i push the card first,i can manage the temps.

and i've set a curve for the fan so when im at load it will maximize the fan speed,since im wearing headphones and i can't hear anything around me anyway :P

my only concern is the life expectancy of the card,im not sure how would it affect it.

I guess It'll last about as long as the capacitors will..last. Not sure what else will fail besides the fans.

 

Like electrolytic caps, polymer (aka solid) caps do die quicker (but at a much slower rate than electrolytic) the warmer they are. Again, keep the whole card as cool as possible when under load. It'll last a long time. 

 

 

Also, keep in mind that overclocking video card only really benefits benchmarks. It does improve fps in games. But not by a lot... By all means overclock. It's enjoyment.

Overclocking isn't as dangerous as some people make it out to be, as long as the card stays nice and cool there is nothing to worry about.
I kept my HD 4870 overclocked and over-volted for five years and the card is still going as strong as it once did.

That being said, the GTX 660 and the 600 series in general doesn't overclock very well do the voltage cap enforced by Nvidia's green light program.
So overclocking won't improve performance significantly to make it worth while.

Don't overvolt, those PCB's are not designed for higher voltages (especially in low to mid-range segment). You might not notice adverse effect, but sure it will be there (I'm not talking about life of the card).

 

It really isn't worth.
