Voltage (Overclock)

[IMadeYouReadThis]

I am new to overclocking but I just learned if you increase your voltage you can go higher on the GPU Clock. Mine is currently at +150 and it goes to about 1550 MHz when playing. However I can't go more than +150 or my driver will stop responding. I heard if you increase voltage you can make it go higher? Should I do it? If so, how much Mv should I put?

You can raise the voltage slider as high as it will go, and then try and see how high you can get the clock speed (and then try and lower the voltage until you find the lowest voltage that will still be stable).

Is that safe? So I just put it at max and lower it until I find one thats good?

Yes, it's safe so long as your temps remain acceptable (anything under 85c is fine). Afterburner/Precision X don't allow you to go further than what's 'safe'. 

 

Put the voltage to max (make sure the temps at max are fine, if they're not then lower it until temps are acceptable) and then find the highest stable clock speed. Once you found the highest stable clock speed then try and see how low you can get the voltage and still have it remain stable.

Try adding 5 on volts and 10 on MHz, if you still crash, try 10 on volts, then 15, then 20, while keeping the MHz the same.

If you still crash after that, so wont it clock any higher.

Another thing to add onto these words is to try and keep it colder.

 

GPU's tend to have a few sweet spots in temps, where they'll overclock an extra 20 or so mhz without extra voltage, due to being colder.

When you try to overclock so will you ether be limited by temprature or by voltage.

I like to figure out which my card is limited by first, then dialing in a stable overclock with acceptable tempratures.

What I meant was:  Your GPU may overclock to 1400 mhz for instance, but not be stable at 70c, but may be stable at 60c.  That's part of the reason people get better OC's on watercooling and other methods, even with the EXACT same voltage. 

 

My 980 Classified likes to do this, 1582 mhz is stable at 1.3v on air as long as the temp doesn't go over 52c, yet it's stable at 1.212volts on water at 1595 mhz.
