How to get max OC on GTX 680

[Jayzied]

Hello guys,

I'm trying to OC my EVGA GTX 680 (reference) into its maximum freqs. However, I can't reach any more than +140mhz on core clock and +550mhz on memory clock. I haven't touched anything about power limit nor voltage.

What can I do to speed up it a little more?

My specs are:
CPU: i5 3330
MB: Gigabyte B75M-DH3
RAM: 16GB DDR3 1600Mhz
PSU: Tacens Radix 750W

Thanks for advance!

You can crank up the core voltage and memory voltage, but why would you want to? That runs the risk of damaging your card. For stock voltages, that's a pretty good overclock as it is.

I just want to increase a little bit the OC because I've seen the same model can reach more freqs (in non-reference cards) and I want to have more perfomance on gaming. Until I'll be able to change my mobo and processor (the next year, I hope, with Broadwell), I though it could be a good idea maximize the GPU power in order to compensate the lack's processor.

EDIT: So, the question is: what's the safest mode to increase the power limit and/or the voltage? Because I've never touched any of them.
