I was wandering what good overvolt is for the PNY GTX 770. With afterburner and percision i noticed that the voltage is locked sort of. You can with percision you can up the voltage a tiny bit. It is like they are locking the card at 75% power
I am running ASUS GTX 770 SLI with max votage 1.210v of both card @ Core speed 1275MHz and memery @8010MHz, with all 5 x 140mm chassis fan full speed running, when with both card full load, the temp @ max 79 C.

Not all cards are the same. Some like the Asus have great VRM's and cooling which can handle more overclocking.
I don't know how the PNY you own is constructed.
If you want to overclock:
a) read about GPU BOOST and understand it well
b) overclock/volt until your system crashes/freezes then back off (I prefer to be at least 50MHz below crash territory).
In general, you should possibly just increase the frequency though I do have to go back and look at GPU BOOST 2 to give better advice as I have a 680.
It appears you overclock using the EVGA software like this:
a) drag power/temp bar
b) raise base frequency
So how well this works depends on your graphics card components. Again, though if you don't have these features then adjust what you do have in small increments then back off when/if you crash.

I tried overclocking raising about 10mhz on the core and about 50mhz on the memory using the heaven benchmark I did this till i got like 100mhz core and 400mhz memory it ran fine on heaven but when i played far cry 3 it crashed after 15 minutes. And you can only adjust the voltage 12mv the bar goes almost to the top but when i look at gpu-z it actually lowers the vddc. wierd
The small bump that MSI Afterburner provides to the power isn't really overvolting the card as much as it's unlocking the power fed to the card (if you're talking about the Power Limit slider bar) so don't worry about cranking it up to help with your overclock. Just make sure you keep an eye on the temps.
