Unfortunately I am not familiar with the exacts on overclocking on Nvidia cards, but what I have picked up is that generally, you dont need to worry about your card spontaneously combusting or anything. Watch your temperatures, the more volts you apply, the hotter it will get, keep it in reasonable range (rule of thumb is below 80 degrees Celsius), and you will be find to play with speeds as much as you like.
Increase your speeds by 25 or 50 mhz at a time, test stability with something like 3Dmark or Heaven:
3Dmark Site: Futuremark - world's most popular benchmarks and PC performance tests
Heaven Site: Heaven DX11 Benchmark | Unigine: real-time 3D engine (game, simulation, visualization and VR)
If you get artifacts, i.e. colourful lines, flickers, dots, etc, button back.
If the overclock crashes, button back. You can recognize this several ways, the whole OS may crash, your screen may go black, your video drivers may stop responding, all signs the overclock is unstable. Generally you aim for the highest possible stable overclock.
On the topic of highest possible stable overclock, I applied more volts in a more direct way to my card via MSI afterburner (I believe this can be used with nVidia cards Fsufan0025), and I have it running stable at 1100mhz core, 1575mhz mem, peaking around 64 degrees Celsius, and I am gonna try push 1200mhz now .
OK that's cool !! ANYBODY ??? I have no clue where to start. In thr BIOS, there's nothing to adjust, that I can see !! What am I missing ??
You use software, not BIOS for graphics cards. I don't know if Nvidia has any native support or anything, try MSI afterburner?

That's all I can offer for Nvidia cards though.
To be clear, a graphics card has it's own BIOS. Software such as EVGA Precision will allow you to overclock your graphics card from a software level, and has the option to apply whatever settings you choose each start up.
Once you find a decent overclock that runs stable and doesn't cause heat issues, you can edit the GPU BIOS and enter those speeds/voltages as it's defaults if you feel the need. This would keep that overclock even if moved to a new PC.
I'd recommend you get EVGA Precision to test different levels of overclocking, and ATI Tool to test for graphic glitches while you play with settings. Once you've got a decent OC, then you can start looking at more permanent measures if you really want to.
I was just about to say Evga precision tool, but ZaLiTH beat me to it, anyway I have that tool and it is a very strait forward tool and guides you well along the ways over overclocking, basically just watch the temps and never increse to much at one time,keep the numbers low and close to each other, and remember that the idle temps may not differ too much while your oc'ing,but your full run temps will be allot different,so check that while your tuning.
